Just a short, simple blog for Bob to share his thoughts.
30 January 2014 • by Bob • IIS, Scripting, IIS Express, PHP
Whenever I am delivering a presentation where I need to use PHP, I typically use a batch file that I wrote in order to rapidly deploy PHP on the system that I am using for my demos. The batch file usually takes less than a second to run, which always seems to amaze people in the audience. As a result, I usually have several people ask me for my batch file after each presentation, so I thought that it would make a good subject for today's blog.
I should mention that I have used this batch file in order to demonstrate PHP with IIS in a variety of scenarios, and one of my favorite demos is when I would borrow someone's laptop and plug in a flash drive where I had IIS Express pre-installed, and then I would run the batch file in this blog to deploy PHP. Next I would launch IIS Express, open a web browser on their system, and then browse to http://localhost/ in order to show that IIS Express was working correctly. Lastly I would write a simple PHP "Hello World" page to show that PHP was up-and-running on their system in a matter of seconds.
That being said, I have to point out that there is a very important prerequisite that you must have in order to follow the steps in the blog: you need to start with a known-good installation of PHP from one of your systems, and I'll explain what I mean by that.
My batch file expects to find a folder containing ready-to-run files for PHP in order to deploy PHP on a new system. I originally obtained my PHP files by using the Web Platform Installer (WebPI) to install PHP, and then I copied the files to my flash drive or some other repository. (Note that WebPI usually installs PHP in the "%ProgramFiles(x86)%\PHP" folder.) If you don't want to use WebPI, you can also download PHP from http://windows.php.net/, but you're on your own for configuration.
Once I have the files from a known-good installation of PHP, I create the following folder structure in the location where I will be storing the files that I use to deploy PHP on other systems:
One thing to note is that the PHP.INI file you use may contain paths which refer to specific directories on the system from which you are copying your PHP files, so you need to make sure that those paths will exist on the system where you deploy PHP.
Here is an example: when I used WebPI to install PHP 5.5 on a system with IIS, it installed PHP into my "%ProgramFiles(x86)%\PHP\v5.5" folder. During the installation process, WebPI updated the PHP file to reflect any paths that need to be defined. At the time that I put together my notes for this blog, those updates mainly applied to the path where PHP expects to find it's extensions:
extension_dir="C:\Program Files (x86)\PHP\v5.5\ext\"
What this means is - if you want to deploy PHP to some other path on subsequent systems, you will need to update at least that line in the PHP.INI file that you are using to deploy PHP. In my particular case, I prefer to deploy PHP to the "%SystemDrive%\PHP" path, but it can be anywhere as long as you update everything accordingly.
The following batch file will deploy the PHP files in the "%SystemDrive%\PHP" folder on your system, and then it will update IIS with the necessary settings for this PHP deployment to work:
@echo off REM Change to the installation folder pushd "%~dp0" REM Cheap test to see if IIS is installed if exist "%SystemRoot%\System32\inetsrv" ( REM Check for the PHP installation files in a subfolder if exist "%~dp0PHP" ( REM Check for an existing installation of PHP if not exist "%SystemDrive%\PHP" ( REM Create the folder for PHP md "%SystemDrive%\PHP" REM Deploy the PHP files xcopy /erhky "%~dp0PHP\*" "%SystemDrive%\PHP" ) pushd "%SystemRoot%\System32\inetsrv" REM Configure the IIS settings for PHP appcmd.exe set config -section:system.webServer/fastCgi /+"[fullPath='%SystemDrive%\PHP\php-cgi.exe',monitorChangesTo='php.ini',activityTimeout='600',requestTimeout='600',instanceMaxRequests='10000']" /commit:apphost appcmd.exe set config -section:system.webServer/fastCgi /+"[fullPath='%SystemDrive%\PHP\php-cgi.exe',monitorChangesTo='php.ini',activityTimeout='600',requestTimeout='600',instanceMaxRequests='10000'].environmentVariables.[name='PHP_FCGI_MAX_REQUESTS',value='10000']" /commit:apphost appcmd.exe set config -section:system.webServer/fastCgi /+"[fullPath='%SystemDrive%\PHP\php-cgi.exe',monitorChangesTo='php.ini',activityTimeout='600',requestTimeout='600',instanceMaxRequests='10000'].environmentVariables.[name='PHPRC',value='%SystemDrive%\PHP']" /commit:apphost appcmd.exe set config -section:system.webServer/handlers /+"[name='PHP_via_FastCGI',path='*.php',verb='GET,HEAD,POST',modules='FastCgiModule',scriptProcessor='%SystemDrive%\PHP\php-cgi.exe',resourceType='Either']" /commit:apphost popd ) ) popd
Once you have all of that in place, it usually takes less than a second to deploy PHP, which is why so many people seem interested during my presentations.
Note that you can deploy PHP for IIS Express just as easily by updating the "%SystemRoot%\System32\inetsrv" paths in the batch file to "%ProgramFiles%\IIS Express" or "%ProgramFiles(x86)%\IIS Express" paths. You can also use this batch file as part of a deployment process for PHP within a web farm; in which case, you will need to pay attention to the paths inside your PHP.INI file which I mentioned earlier.

20 September 2013 • by Bob • IIS, Scripting, WebDAV
A couple of years ago I wrote a blog that was titled "How to create an HTML Application to configure your WebDAV Redirector settings", where I showed how to use HTMLA to create a simple editor for most of the WebDAV Redirector settings. These settings have no other user interface, so prior to my blog post users had to manually edit the registry in order to modify their WebDAV Redirector settings.

In the past two years since I wrote that blog, I have found myself using that simple application so often that I now keep it in my personal utilities folder on my SkyDrive so I can have it with me no matter where I am travelling. But that being said, I ran into an interesting situation the other day that made me want to update the application, so I thought that it was time to write a new blog with the updated changes.
Here's what happened - I had opened my application for modifying my WebDAV Redirector settings, but then something happened which distracted me, and then I headed off to lunch before I committed my changes to the registry. When I came back to my office, I noticed that my WebDAV Redirector settings application was still open and I clicked the Exit Application button. The application popped up a dialog which informed me that I had changes that hadn't been saved to the registry, but I forgot what they were. This put me in a quandary - I could simply click Yes and hope for the best, or I could click No and lose whatever changes that I had made and re-open the application to start over.
It was at that time that I thought to myself, "If only I had a Reset Values button..."
By now you can probably see where this blog is going, and here's what the new application looks like - it's pretty much the same as the last application, with the additional button that allows you to reset your values without exiting the application. (Note - the application will prompt you for confirmation if you attempt to reset the values and you have unsaved changes.)

To create this HTML Application, you need to use the same steps as my last blog: save the following HTMLA code as "WebDAV Redirector Settings.hta" to your computer, and then double-click its icon to run the application.

28 June 2013 • by Bob • Scripting, WebMatrix
I recently had the opportunity to take a day-long class about jQuery from the good folks at Wintellect. The class went great, and I wrote all of my code for the class in WebMatrix. You might recall from my previous blogs that I am a big fan of WebMatrix, but at first there was one thing that was missing from WebMatrix's arsenal of cool features; in order for WebMatrix to really be useful as an editor for jQuery, I really wanted to have IntelliSense support for jQuery. Thankfully, even though IntelliSense support for jQuery is not built-in, adding IntelliSense for jQuery is extremely easy, and I thought that would make a great subject for today's blog.
To start things off, let's take a look at a jQuery sample that is little more than a Hello World sample:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8" /> <title>jQuery Test Page</title> </head> <body> <script src="http://ajax.microsoft.com/ajax/jQuery/jquery-2.0.0.min.js" type="text/javascript"></script> <script> $(function() { $("#bar").text($("#foo").text()); $("#foo").text("This is some custom text"); });
</script> <h1 id="foo">This is the first line</h1> <h2 id="bar">This is the second line</h2> </body> </html>
This example does very little: it loads the jQuery library from Microsoft's AJAX Content Delivery Network (CDN), and it uses jQuery to replace the text in a couple of HTML tags. (The example isn't really important - getting IntelliSense to work is the topic du jour.) This sample would look like the following illustration if you opened it in WebMatrix 3:
When you are using a JavaScript library for which there is no built-in support, Microsoft's developer tools allow you to add IntelliSense support by adding Reference Directives to your page, and the files that you would use for your reference directives are available at the same Microsoft CDN where you can get the jQuery library:
http://www.asp.net/ajaxlibrary/cdn.ashx
In order to use IntelliSense for jQuery, you need to download the appropriate jquery-n.n.n-vsdoc.js file for the version of jQuery that you are using and store that in your website. For example, if you are using jQuery version 2.0.0, you would add a script reference to the CDN path for http://ajax.aspnetcdn.com/ajax/jQuery/jquery-2.0.0.min.js, and you would download the http://ajax.aspnetcdn.com/ajax/jQuery/jquery-2.0.0-vsdoc.js file for your website.
Like many developers, I usually add a folder named scripts in the root of my website, and this is where I will typically store the jquery-n.n.n-vsdoc.js file that I am using. Once you have added the appropriate jquery-n.n.n-vsdoc.js file to your website, all that you need to do is add the appropriate reference directive to your script, as I demonstrate in the highlighted section of the following code sample:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8" /> <title>jQuery Test Page</title> </head> <body> <script src="http://ajax.microsoft.com/ajax/jQuery/jquery-2.0.0.min.js" type="text/javascript"></script> <script> /// <reference path="scripts/jquery-2.0.0-vsdoc.js" /> $(function() { $("#bar").text($("#foo").text()); $("#foo").text("This is some custom text"); });
</script> <h1 id="foo">This is the first line</h1> <h2 id="bar">This is the second line</h2> </body> </html>
Once you have added the reference directive for your jquery-n.n.n-vsdoc.js file, IntelliSense will begin working for jQuery in WebMatrix, as shown in the following illustration:
One last thing that I would like to mention is that is always a good idea to load JavaScript libraries like jQuery from a CDN, and there are lots of CDNs to choose from. There are some additional steps that you can take to ensure that your website works with jQuery even if the CDN is down, but that subject is outside the scope of this blog. ;-]

28 March 2013 • by Bob • IIS, Scripting, FTP
A customer asked me a question a little while ago that provided me the opportunity to recycle some code that I had written many years ago. In so doing, I also made a bunch of updates to the code to make it considerably more useful, and I thought that it would make a great blog.
Here's the scenario: a customer had hundreds of user accounts created, and he wanted to use the FTP service's User Isolation features to restrict each user to a specific folder on his FTP site. Since it would take a long time to manually create a folder for each user account, the customer wanted to know if there was a way to automate the process. As it turns out, I had posted a very simple script in the IIS.net forums several years ago that did something like what he wanted; and that script was based off an earlier script that I had written for someone else back in the IIS 6.0 days.
One quick reminder - FTP User Isolation uses a specific set of folders for user accounts, which are listed in the table below.
User Account Types | Home Directory Syntax |
---|---|
Anonymous users | %FtpRoot%\LocalUser\Public |
Local Windows user accounts
(Requires Basic authentication.) |
%FtpRoot%\LocalUser\%UserName% |
Windows domain accounts
(Requires Basic authentication.) |
%FtpRoot%\%UserDomain%\%UserName% |
Note: %FtpRoot% is the root directory for your FTP site: for example, C:\Inetpub\Ftproot.
That being said, I'm a big believer in recycling code, so I found the last version of that script that I gave to someone and I made a bunch of changes to it so it would be more useful for the customer. What that in mind, here's the resulting script, and I'll explain a little more about what it does after the code sample.
Option Explicit ' Define the root path for the user isolation folders. ' This should be the root directory for your FTP site. Dim strRootPath : strRootPath = "C:\Inetpub\wwwroot\" ' Define the name of the domain or the computer to use. ' Leave this blank for the local computer. Dim strComputerOrDomain : strComputerOrDomain = "" ' Define the remaining script variables. Dim objFSO, objCollection, objUser, objNetwork, strContainerName ' Create a network object; used to query the computer name. Set objNetwork = WScript.CreateObject("WScript.Network") ' Create a file system object; used to creat folders. Set objFSO = CreateObject("Scripting.FileSystemObject") ' Test if the computer name is null. If Len(strComputerOrDomain)=0 Or strComputerOrDomain="." Then ' If so, define the local computer name as the account repository. strComputerOrDomain = objNetwork.ComputerName End If ' Verify that the root path exists. If objFSO.FolderExists(strRootPath) Then ' Test if the script is using local users. If StrComp(strComputerOrDomain,objNetwork.ComputerName,vbTextCompare)=0 Then ' If so, define the local users container path. strContainerName = "LocalUser" ' And define the users collection as local. Set objCollection = GetObject("WinNT://.") Else ' Otherwise, use the source name as the path. strContainerName = strComputerOrDomain ' And define the users collection as remote. Set objCollection = GetObject("WinNT://" & strComputerOrDomain & "") End If ' Append trailing backslash if necessary. If Right(strRootPath,1)<>"\" Then strRootPath = strRootPath & "\" ' Define the adjusted root path for the container folder. strRootPath = strRootPath & strContainerName & "\" ' Test if the container folder already exists. If objFSO.FolderExists(strRootPath)=False Then ' Create the container folder if necessary. objFSO.CreateFolder(strRootPath) End If ' Specify the collection filter for user objects only. objCollection.Filter = Array("user") ' Loop through the users collection. For Each objUser In objCollection ' Test if the user's account is enabled. If objUser.AccountDisabled = False Then ' Test if the user's folder already exists. If objFSO.FolderExists(strRootPath & "\" & objUser.Name)=False Then ' Create the user's folder if necessary. objFSO.CreateFolder(strRootPath & "\" & objUser.Name) End If End If Next End If
I documented this script in great detail, so it should be self-explanatory for the most part. But just to be on the safe side, here's an explanation of what this script is doing when you run it on your FTP server:
That's all for now. ;-]

28 February 2013 • by Bob • LogParser, Scripting, XML
In Part 6 of this series, I showed how to create a very basic COM-based input format provider for Log Parser. I wrote that blog post as a follow-up to an earlier blog post where I had written a more complex COM-based input format provider for Log Parser that worked with FTP RSCA events. My original blog post had resulted in several requests for me to write some easier examples about how to get started writing COM-based input format providers for Log Parser, and those appeals led me to write my last blog post:
Advanced Log Parser Part 6 - Creating a Simple Custom Input Format Plug-In
The example in that blog post simply returns static data, which was the easiest example that I could demonstrate.
For this follow-up blog post, I will illustrate how to create a simple COM-based input format plug-in for Log Parser that you can use as a generic provider for consuming data in text-based log files. Please bear in mind that this is just an example to help developers get started writing their own COM-based input format providers; you might be able to accomplish some of what I will demonstrate in this blog post by using the built-in Log Parser functionality. That being said, this still seems like the best example to help developers get started because consuming data in text-based log files was the most-often-requested example that I received.
In my earlier blog posts, I mentioned that a COM plug-in has to support several public methods. You can look at those blog posts when you get the chance, but it is a worthwhile endeavor for me to copy the following information from those blog posts since it is essential to understanding how the code sample in this blog post is supposed to work.
Method Name | Description |
---|---|
OpenInput | Opens your data source and sets up any initial environment settings. |
GetFieldCount | Returns the number of fields that your plug-in will provide. |
GetFieldName | Returns the name of a specified field. |
GetFieldType | Returns the datatype of a specified field. |
GetValue | Returns the value of a specified field. |
ReadRecord | Reads the next record from your data source. |
CloseInput | Closes your data source and cleans up any environment settings. |
Once you have created and registered a COM-based input format plug-in, you call it from Log Parser by using something like the following syntax:
logparser.exe "SELECT * FROM FOO" -i:COM -iProgID:BAR
In the preceding example, FOO is a data source that makes sense to your plug-in, and BAR is the COM class name for your plug-in.
As I have done in my previous two blog posts about creating COM-based input format plug-ins, I'm going to demonstrate how to create a COM component by using a scriptlet since no compilation is required. This generic plug-in will parse any text-based log files where records are delimited by CRLF sequences and fields/columns are delimited by a separator that is defined as a constant in the code sample.
To create the sample COM plug-in, copy the following code into a text file, and save that file as "Generic.LogParser.Scriptlet.sct" to your computer. (Note: The *.SCT file extension tells Windows that this is a scriptlet file.)
<SCRIPTLET> <registration Description="Simple Log Parser Scriptlet" Progid="Generic.LogParser.Scriptlet" Classid="{4e616d65-6f6e-6d65-6973-526f62657274}" Version="1.00" Remotable="False" /> <comment> EXAMPLE: logparser "SELECT * FROM 'C:\foo\bar.log'" -i:COM -iProgID:Generic.LogParser.Scriptlet </comment> <implements id="Automation" type="Automation"> <method name="OpenInput"> <parameter name="strFileName"/> </method> <method name="GetFieldCount" /> <method name="GetFieldName"> <parameter name="intFieldIndex"/> </method> <method name="GetFieldType"> <parameter name="intFieldIndex"/> </method> <method name="ReadRecord" /> <method name="GetValue"> <parameter name="intFieldIndex"/> </method> <method name="CloseInput"> <parameter name="blnAbort"/> </method> </implements> <SCRIPT LANGUAGE="VBScript"> Option Explicit ' Define the column separator in the log file.

ReadRecord = True End If End If End Function </SCRIPT> </SCRIPTLET>
After you have saved the scriptlet code to your computer, you register it by using the following syntax:
regsvr32 Generic.LogParser.Scriptlet.sct
At the very minimum, you can now use the COM plug-in with Log Parser by using syntax like the following:
logparser "SELECT * FROM 'C:\Foo\Bar.log'" -i:COM -iProgID:Generic.LogParser.Scriptlet
Next, let's analyze what this sample does.
Here are the different parts of the scriptlet and what they do:
Next, let's look at how to use the sample.
As a sample log file for this blog, I'm going to use the data in the Sample XML File (books.xml) from MSDN. By running a quick Log Parser query that I will show later, I was able to export data from the XML file into text file named "books.log" that represents an example of a simple log file format that I have had to work with in the past:

In this example, the data is pretty easy to understand - the first row contains the list of field/column names, and the fields/columns are separated by the pipe ("|") character throughout the log file. That being said, you could easily change my sample code to use a different delimiter that your custom log files use.
With that in mind, let's look at some Log Parser examples.
The first thing that you should try is to simply retrieve data from your custom plug-in, and the following query should serve as an example:
logparser "SELECT * FROM 'C:\sample\books.log'" -i:COM -iProgID:Generic.LogParser.Scriptlet
The above query will return results like the following:

While the above example works a good proof-of-concept for functionality, it's not overly useful, so let's look at additional examples.
Once you have established that you can retrieve data from your custom plug-in, you can start taking advantage of Log Parser's features to process your log file data. In this example, I will use several of the built-in functions to reformat the data:
logparser "SELECT id AS ID, TO_DATE(publish_date) AS Date, author AS Author, SUBSTR(title,0,20) AS Title, STRCAT(TO_STRING(TO_INT(FLOOR(price))),SUBSTR(TO_STRING(price),INDEX_OF(TO_STRING(price),'.'),3)) AS Price FROM 'C:\sample\books.log'" -i:COM -iProgID:Generic.LogParser.Scriptlet
The above query will return results like the following:
ID | Date | Author | Title | Price | ||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|

This example reformats the dates and prices a little nicer, and it truncates the book titles at 20 characters so they fit a little better on some screens.
In addition to simply reformatting your data, you can use Log Parser to group, sort, count, total, etc., your data. The following example illustrates how to use Log Parser to count the number of books by author in the log file:
logparser "SELECT author AS Author, COUNT(Title) AS Books FROM 'C:\sample\books.log' GROUP BY Author ORDER BY Author" -i:COM -iProgID:Generic.LogParser.Scriptlet
The above query will return results like the following:
Author | Books | ||||||||||

The results are pretty straight-forward: Log Parser parses the data and presents you with a list of alphabetized authors and the total number of books that were written by each author.
You can also use data from your custom log file to create charts through Log Parser. If I modify the above example, all that I need to do is add a few parameters to create a chart:
logparser "SELECT author AS Author, COUNT(Title) AS Books INTO Authors.gif FROM 'C:\sample\books.log' GROUP BY Author ORDER BY Author" -i:COM -iProgID:Generic.LogParser.Scriptlet -fileType:GIF -groupSize:800x600 -chartType:Pie -categories:OFF -values:ON -legend:ON
The above query will create a chart like the following:
I admit that it's not a very pretty-looking chart - you can look at the other posts in my Log Parser series for some examples about making Log Parser charts more interesting.
In this blog post and my last post, I have illustrated a few examples that should help developers get started writing their own custom input format plug-ins for Log Parser. As I mentioned in each of the blog posts where I have used scriptlets for the COM objects, I would typically use C# or C++ to create a COM component, but using a scriptlet is much easier for demos because it doesn't require installing Visual Studio and compiling a DLL.
There is one last thing that I would like to mention before I finish this blog; I mentioned earlier that I had used Log Parser to reformat the sample Books.xml file into a generic log file that I could use for the examples in this blog. Since Log Parser supports XML as an input format and it allows you to customize your output, I wrote the following simple Log Parser query to reformat the XML data into a format that I had often seen used for text-based log files:
logparser.exe "SELECT id,publish_date,author,title,price INTO books.log FROM books.xml" -i:xml -o:tsv -headers:ON -oSeparator:"|"
Actually, this ability to change data formats is one of the hidden gems of Log Parser; I have often used Log Parser to change the data from one type of log file to another - usually so that a different program can access the data. For example, if you were given the log file with a pipe ("|") delimiter like I used as an example, you could easily use Log Parser to convert that data into the CSV format so you could open it in Excel:
logparser.exe "SELECT id,publish_date,author,title,price INTO books.csv FROM books.log" -i:tsv -o:csv -headers:ON -iSeparator:"|" -oDQuotes:on
I hope these past few blog posts help you to get started writing your own custom input format plug-ins for Log Parser.
That's all for now. ;-)

In Part 4 of this series, I illustrated how to create a new COM-based input provider for Log Parser from a custom input format:
Advanced Log Parser Charts Part 4 - Adding Custom Input Formats
For the sample that I published in that blog, I wrote a plug-in that consumed FTP RSCA events, which is highly structured data, and it added a lot of complexity to my example. In the past ten months or so since I published my original blog, I've had several requests for additional information about how to get started writing COM-based input formats for Log Parser, so it occurred to me that perhaps I could have shown a simpler example to get people started instead of diving straight into parsing RSCA data. ;-)
With that in mind, I thought that I would write a couple of blog posts with simpler examples to help anyone who wants to get started writing custom input formats for Log Parser.
For this blog post, I will show you how to create a very basic COM-based input format provider for Log Parser that simply returns static data; you could use this sample as a template to quickly get up-and-running with the basic concepts. (I promise to follow this blog with another real-world example that is still easier-to-use than my RSCA example.)
In the blog that I referred to earlier, I mentioned that a COM plug-in has to support the following public methods:
Method Name | Description |
---|---|
OpenInput |
Opens your data source and sets up any initial environment settings. |
GetFieldCount |
Returns the number of fields that your plug-in will provide. |
GetFieldName |
Returns the name of a specified field. |
GetFieldType |
Returns the datatype of a specified field. |
GetValue |
Returns the value of a specified field. |
ReadRecord |
Reads the next record from your data source. |
CloseInput |
Closes your data source and cleans up any environment settings. |
Once you have created and registered a COM plug-in, you call it by using something like the following syntax:
logparser.exe "SELECT * FROM FOO" -i:COM -iProgID:BAR
In the preceding example, FOO is a data source that makes sense to your plug-in, and BAR is the COM class name for your plug-in.
Once again, I'm going to demonstrate how to create a COM component by using a scriptlet, which I like to use for demos because they are quick to design, they're easily portable, and updates take place immediately since no compilation is required. (All of that being said, if I were writing a real COM plug-in for Log Parser, I would use C# or C++.)
To create the sample COM plug-in, copy the following code into a text file, and save that file as "Simple.LogParser.Scriptlet.sct" to your computer. (Note: The *.SCT file extension tells Windows that this is a scriptlet file.)
<SCRIPTLET> <registration Description="Simple Log Parser Scriptlet" Progid="Simple.LogParser.Scriptlet" Classid="{4e616d65-6f6e-6d65-6973-526f62657274}" Version="1.00" Remotable="False" /> <comment> EXAMPLE: logparser "SELECT * FROM FOOBAR" -i:COM -iProgID:Simple.LogParser.Scriptlet </comment> <implements id="Automation" type="Automation"> <method name="OpenInput"> <parameter name="strValue"/> </method> <method name="GetFieldCount" /> <method name="GetFieldName"> <parameter name="intFieldIndex"/> </method> <method name="GetFieldType"> <parameter name="intFieldIndex"/> </method> <method name="ReadRecord" /> <method name="GetValue"> <parameter name="intFieldIndex"/> </method> <method name="CloseInput"> <parameter name="blnAbort"/> </method> </implements> <SCRIPT LANGUAGE="VBScript"> Option Explicit Const MAX_RECORDS = 5 Dim intRecordCount ' -------------------------------------------------------------------------------- ' Open the input session.

After you have saved the scriptlet code to your computer, you register it by using the following syntax:
regsvr32 Simple.LogParser.Scriptlet.sct
At the very minimum, you can now use the COM plug-in with Log Parser by using syntax like the following:
logparser "SELECT * FROM FOOBAR" -i:COM -iProgID:Simple.LogParser.Scriptlet
This will return results like the following:
INTEGER | REAL | STRING | TIMESTAMP | NULL |
---|---|---|---|---|

Next, let's analyze what this sample does.
Here are the different parts of the scriptlet and what they do:
OpenInput()
method opens your data source, although in this example it only initializes the record count. (Note that the value that is passed to the method will be ignored in this example.)CloseInput()
method would normally clean up your session, (e.g. close a data file or database, etc.), but it doesn't do anything in this example.GetFieldCount()
method returns the number of data fields in each record of your data, which is static in this example.GetFieldName()
method returns the name of a field that is passed to the method as a number; the names are static in this example.GetFieldType()
method returns the data type of a field that is passed to the method as a number, which are statically-defined in this example. As a reminder, Log Parser supports the following five data types for COM plug-ins: TYPE_INTEGER
, TYPE_REAL
, TYPE_STRING
, TYPE_TIMESTAMP
, and TYPE_NULL
.GetValue()
method returns the data value of a field that is passed to the method as a number. Once again, the data values are statically-defined in this example.ReadRecord()
method moves to the next record in your data set; this method returns True if there is data to read, or False when the end of data is reached. In this example, the method increments the record counter and sets the status based on whether the maximum number of records has been reached.That wraps up the simplest example that I could put together of a COM-based input provider for Log Parser. In my next blog, I'll show how to create a generic COM-based input provider for Log Parser that you can use to parse text-based log files.

31 January 2013 • by Bob • Scripting, FTP, Extensibility
I was recently creating a new authentication provider using FTP extensibility, and I ran into a weird behavior that I had seen before. With that in mind, I thought my situation would make a great blog subject because someone else may run into it.
Here are the details of the situation: let's say that you are developing a new FTP provider for IIS, and your code changes never seem to take effect. Your provider appears to be working, it's just that any new functionality is not reflected in your provider's behavior. You restart the FTP service as a troubleshooting step, but that does not appear to make any difference.
I'll bypass mentioning any other troubleshooting tasks and cut to the chase - if you read my Changing the Identity of the FTP 7 Extensibility Process blog post a year ago, you will recall that I mentioned that all custom FTP extensibility providers are executed through COM+ in a DLLHOST.exe process. When you restart the FTP service, that should clean up the DLLHOST.EXE process that is being used for FTP extensibility. However, if you are developing custom FTP providers and the DLLHOST.EXE process is not terminated by the FTP service, you may find yourself in a situation where you have a DLLHOST.EXE process in memory that contains an older copy of your provider, which will not be removed from memory until the DLLHOST.EXE process for FTP extensibility has been forcibly terminated.
If you have read some of my earlier blog posts or walkthroughs on IIS.NET, you may have noticed that I generally like to use a few pre-build and post-build commands in my FTP projects; usually I add these commands in order to to automatically register/unregister my FTP providers in the Global Assembly Cache (GAC).
With a little modification and some command-line wizardry, you can automate the termination of any orphaned DLLHOST.EXE processes that are being used for FTP extensibility. With that in mind, here are some example pre-build/post-build commands that will unregister/reregister your provider in the GAC, restart the FTP service, and terminate any orphaned FTP extensibility DLLHOST.EXE processes.
Note: The following syntax was written using Visual Studio 2010; you would need to change "%VS100COMNTOOLS%" to "%VS90COMNTOOLS%" for Visual Studio 2008 or "%VS110COMNTOOLS%" for Visual Studio 2012.
Pre-build Commands:
net stop ftpsvc
call "%VS100COMNTOOLS%\vsvars32.bat">nul
cd /d "$(TargetDir)"
gacutil.exe /uf "$(TargetName)"
for /f "usebackq tokens=1,2* delims=," %%a in (`tasklist /fi "MODULES eq Microsoft.Web.FtpServer.*" /fi "IMAGENAME eq DLLHOST.EXE" /fo csv ^| find /i "dllhost.exe"`) do taskkill /f /pid %%b
Post-build Commands:
call "%VS100COMNTOOLS%\vsvars32.bat">nul
gacutil.exe /if "$(TargetPath)"
net start ftpsvc
The syntax is a little tricky for the FOR statement, so be carefully when typing or copying/pasting that into your projects. For example, you need to make sure that all of the code from the FOR statement through the TASKKILL command are on the same line in your project's properties.
When you compile your provider, Visual Studio should display something like the following:
------ Rebuild All started: Project: FtpBlogEngineNetAuthentication, Configuration: Release Any CPU ------
The Microsoft FTP Service service is stopping.
The Microsoft FTP Service service was stopped successfully.

The Microsoft FTP Service service is starting.
The Microsoft FTP Service service was started successfully.
========== Rebuild All: 1 succeeded, 0 failed, 0 skipped ==========
If you analyze the output from the build process, you will see that the commands in my earlier samples stopped the FTP service, removed the existing assembly from the GAC, terminated any orphaned DLLHOST.EXE processes, registered the newly-built DLL in the GAC, and then restarted the FTP service.
By utilizing these pre-build/post-build commands, I have been able to work around situations where a DLLHOST.EXE process is being orphaned and caching old assemblies in memory.

03 October 2012 • by Bob • IIS, Scripting, FTP, Extensibility, IIS, Scripting, FTP, Extensibility
I was recently contacted by someone who was trying to use Windows Management Instrumentation (WMI) code to stop and restart FTP websites by using code that he had written for IIS 6.0; his code was something similar to the following:
Option Explicit On Error Resume Next Dim objWMIService, colItems, objItem ' Attach to the IIS service. Set objWMIService = GetObject("winmgmts:\root\microsoftiisv2") ' Retrieve the collection of FTP sites. Set colItems = objWMIService.ExecQuery("Select * from IIsFtpServer") ' Loop through the sites collection. For Each objItem in colItems ' Restart one single website. If (objItem.Name = "MSFTPSVC/1") Then Err.Clear objItem.Stop If (Err.Number <> 0) Then WScript.Echo Err.Number objItem.Start If (Err.Number <> 0) Then WScript.Echo Err.Number End If Next
The problem that the customer was seeing is that this query did not return the list of FTP-based websites for IIS 7.0 or IIS 7.5 (called IIS7 henceforth), although changing the class in the query from IIsFtpServer to IIsWebServer would make the script work with HTTP-based websites those versions of IIS7.
The problem with the customer's code was that he is using WMI to manage IIS7; this relies on our old management APIs that have been deprecated, although part of that model is partially available through the metabase compatibility feature in IIS7. Here's what I mean by "partially": only a portion of the old ADSI/WMI objects are available, and unfortunately FTP is not part of the objects that can be scripted through the metabase compatibility feature in IIS7.
That being said, what the customer wants to do is still possible through scripting in both IIS7 and IIS8, and the following sample shows how to loop through all of the sites, determine which sites have FTP bindings, and then stop/start FTP for each site. To use this script, copy the code into a text editor like Windows Notepad and save it with a name like "RestartAllFtpSites.vbs" to your system, then double-click the file to run it.
' Temporarily disable breaking on runtime errors. On Error Resume Next ' Create an Admin Manager object. Set adminManager = CreateObject("Microsoft.ApplicationHost.AdminManager") adminManager.CommitPath = "MACHINE/WEBROOT/APPHOST" ' Test for commit path support. If Err.Number <> 0 Then Err.Clear ' Create a Writable Admin Manager object. Set adminManager = CreateObject("Microsoft.ApplicationHost.WritableAdminManager") adminManager.CommitPath = "MACHINE/WEBROOT/APPHOST" If Err.Number <> 0 Then WScript.Quit End If ' Resume breaking on runtime errors. On Error Goto 0 ' Retrieve the sites collection. Set sitesSection = adminManager.GetAdminSection("system.applicationHost/sites", "MACHINE/WEBROOT/APPHOST") Set sitesCollection = sitesSection.Collection ' Loop through the sites collection. For siteCount = 0 To CInt(sitesCollection.Count)-1 isFtpSite = False ' Determine if the current site is an FTP site by checking the bindings. Set siteElement = sitesCollection(siteCount) Set bindingsCollection = siteElement.ChildElements.Item("bindings").Collection For bindingsCount = 0 To CInt(bindingsCollection.Count)-1 Set bindingElement = bindingsCollection(bindingsCount) If StrComp(CStr(bindingElement.Properties.Item("protocol").Value),"ftp",vbTextCompare)=0 Then isFtpSite = True Exit For End If Next ' If it's an FTP site, start and stop the site. If isFtpSite = True Then Set ftpServerElement = siteElement.ChildElements.Item("ftpServer") ' Create an instance of the Stop method. Set stopFtpSite = ftpServerElement.Methods.Item("Stop").CreateInstance() ' Execute the method to stop the FTP site. stopFtpSite.Execute() ' Create an instance of the Start method. Set startFtpSite = ftpServerElement.Methods.Item("Start").CreateInstance() ' Execute the method to start the FTP site. startFtpSite.Execute() End If Next
And the following code sample shows how to stop/start a single FTP site. To use this script, copy the code into a text editor like Windows Notepad, rename the site name appropriately for one of your FTP sites, save it with a name like "RestartContosoFtpSite.vbs" to your system, then double-click the file to run it.
' Temporarily disable breaking on runtime errors. On Error Resume Next ' Create an Admin Manager object. Set adminManager = CreateObject("Microsoft.ApplicationHost.AdminManager") adminManager.CommitPath = "MACHINE/WEBROOT/APPHOST" ' Test for commit path support. If Err.Number <> 0 Then Err.Clear ' Create a Writable Admin Manager object. Set adminManager = CreateObject("Microsoft.ApplicationHost.WritableAdminManager") adminManager.CommitPath = "MACHINE/WEBROOT/APPHOST" If Err.Number <> 0 Then WScript.Quit End If ' Resume breaking on runtime errors. On Error Goto 0 ' Retrieve the sites collection. Set sitesSection = adminManager.GetAdminSection("system.applicationHost/sites", "MACHINE/WEBROOT/APPHOST") Set sitesCollection = sitesSection.Collection ' Locate a specific site. siteElementPos = FindElement(sitesCollection, "site", Array("name", "ftp.contoso.com")) If siteElementPos = -1 Then WScript.Echo "Site was not found!" WScript.Quit End If ' Determine if the selected site is an FTP site by checking the bindings. Set siteElement = sitesCollection(siteElementPos) Set bindingsCollection = siteElement.ChildElements.Item("bindings").Collection For bindingsCount = 0 To CInt(bindingsCollection.Count)-1 Set bindingElement = bindingsCollection(bindingsCount) If StrComp(CStr(bindingElement.Properties.Item("protocol").Value),"ftp",vbTextCompare)=0 Then isFtpSite = True Exit For End If Next ' If it's an FTP site, start and stop the site. If isFtpSite = True Then Set ftpServerElement = siteElement.ChildElements.Item("ftpServer") ' Create an instance of the Stop method. Set stopFtpSite = ftpServerElement.Methods.Item("Stop").CreateInstance() ' Execute the method to stop the FTP site. stopFtpSite.Execute() ' Create an instance of the Start method. Set startFtpSite = ftpServerElement.Methods.Item("Start").CreateInstance() ' Execute the method to start the FTP site. startFtpSite.Execute() End If ' Locate and return the index for a specific element in a collection. Function FindElement(collection, elementTagName, valuesToMatch) For i = 0 To CInt(collection.Count) - 1 Set elem = collection.Item(i) If elem.Name = elementTagName Then matches = True For iVal = 0 To UBound(valuesToMatch) Step 2 Set prop = elem.GetPropertyByName(valuesToMatch(iVal)) value = prop.Value If Not IsNull(value) Then value = CStr(value) End If If Not value = CStr(valuesToMatch(iVal + 1)) Then matches = False Exit For End If Next If matches Then Exit For End If End If Next If matches Then FindElement = i Else FindElement = -1 End If End Function
I hope this helps!

25 August 2012 • by Bob • LogParser, Scripting
In Part 5 of this series, I'll show you how to create a generic script that you can use to add some color to your Log Parser charts. As I mentioned in Part 1 of this series, the default colors for Log parser charts are really dull and boring. For example, if I parse one month's worth of log files from one of my low-volume websites with the following query:
logparser.exe "SELECT date,COUNT(*) AS Hits INTO HITS.gif FROM *.log GROUP BY date ORDER BY date" -i:w3c -o:CHART -chartType:ColumnClustered -chartTitle:"" -q:ON
Log Parser will create the following ugly daily hits chart:
Here's the background story for this blog: I have a collection of scripts that I use to format my charts, several of which have faithfully served as the fodder for this blog series. With that in mind, I had a situation recently where I was querying logs with a series of data just like this, and of course the resulting charts were kind of hideous to look at. In one of the scripts that I often use, I create an array of colors to use, and then I apply the various colors to the individual data points in the series.
In the past I have always hard-coded the length for the array of colors based on the data that I am working with, but in this situation I had no idea how many data points I would have, so I decided to put together a quick script with an array that would work with a series of any size.
Here's the resulting script:
// Set a default color for the chart's data. chart.SeriesCollection(0).Interior.Color = "#ffcccc"; // Define a short array of colors. var colors = [ "#ffff99", "#ff99ff", "#ff9999", "#99ffff", "#99ff99", "#9999ff", "#ffffcc", "#ffccff", "#ffcccc", "#ccffff", "#ccffcc", "#ccccff" ]; // Loop through the data points in the series. for (x=0;x<chart.SeriesCollection(0).Points.Count;++x) { // Set the color for the data point based on modulo division of the array length. chart.SeriesCollection(0).Points(x).Interior.Color = colors[x % colors.length ]; }
That's all that there is to the script - it's pretty simple. If I take the above script and save it as "FormatChart.js", I can use that script with my Log Parser query from earlier by adding an extra parameter to the command:
logparser.exe "SELECT date,COUNT(*) AS Hits INTO HITS.gif FROM *.log GROUP BY date ORDER BY date" -i:w3c -o:CHART -chartType:ColumnClustered -chartTitle:"" -q:ON -config:FormatChart.js
Now Log Parser will create the following daily hits chart with a great deal more color to it:
Okay - perhaps that's not the best color palette, but you get the idea. It looks even better when I change the query to use 3D charts:
logparser.exe "SELECT date,COUNT(*) AS Hits INTO HITS.gif FROM *.log GROUP BY date ORDER BY date" -i:w3c -o:CHART -chartType:Column3D -chartTitle:"" -q:ON -config:FormatChart.js
The above query creates the following chart:
I'd like to make a quick change to the script in order to make it work a little better with a pie chart:
// Set a default color for the chart's data. chart.SeriesCollection(0).Interior.Color = "#cccccc"; // Define a short array of colors. var colors = [ "#cc3333", "#3333cc", "#33cc33", "#33cccc", "#cccc33", "#cc33cc" ]; // Loop through the data points in the series. for (x=0;x<chart.SeriesCollection(0).Points.Count;++x) { // Set the color for the data point based on modulo division of the array length. chart.SeriesCollection(0).Points(x).Interior.Color = colors[x % colors.length ]; } // Rotate the chart 180 degrees - just so it looks a little better. chartSpace.Charts(0).PlotArea.RotateClockwise(); chartSpace.Charts(0).PlotArea.RotateClockwise();
For this query I'd like to see a break down by HTTP status, and this necessitates some small change to the Log parser query:
logparser.exe "SELECT sc-status AS Status,COUNT(*) AS Hits INTO HITS.gif FROM *.log GROUP BY Status ORDER BY Status" -i:w3c -o:CHART -chartType:PieExploded3D -chartTitle:"" -q:ON -config:FormatChart.js
The above query creates the following chart:
That wraps it up for this blog - I hope that I've given you some ideas for ways that you can easily add some colors to some dull-looking Log Parser charts.

06 July 2012 • by Bob • Scripting, XML
I was working with an application recently that stored all of its settings in a large XML file, however, when I opened the XML in Windows Notepad, all I saw was a large blob of tags and text - there was no structured formatting to the XML, and that made it very difficult to change some of settings by hand. (Okay - I realize that some of you are probably thinking to yourselves, maybe I wasn't supposed to be editing those settings by hand - but that's just the way I do things around here... if I can't customize every setting to my heart's content, then it's just not worth using.)
In any event, I'll give you an example of what I mean by using the example XML database that's provided on MSDN at the following URL:
http://msdn.microsoft.com/en-us/library/windows/desktop/ms762271.aspx
Note - the entire XML file would be too long to repost here, so I'll just include an unstructured except from that file that resembles what my other XML looked like when I opened the file in Windows Notepad:
<?xml version="1.0"?><catalog><book id="bk101"><author>Gambardella, Matthew</author><title>XML Developer's Guide</title><genre>Computer</genre><price>44.95</price><publish_date>2000-10-01</publish_date><description>An in-depth look at creating applications with XML.</description></book><book id="bk102"><author>Ralls, Kim</author><title>Midnight Rain</title><genre>Fantasy</genre><price>5.95</price><publish_date>2000-12-16</publish_date><description>A former architect battles corporate zombies, an evil sorceress, and her own childhood to become queen of the world.</description></book><book id="bk103"><author>Corets, Eva</author><title>Maeve Ascendant</title><genre>Fantasy</genre><price>5.95</price><publish_date>2000-11-17</publish_date><description>After the collapse of a nanotechnology society in England, the young survivors lay the foundation for a new society.</description></book></catalog>
This is obviously difficult to read, and even more so when you are dealing with hundreds or thousands of lines of XML code. What would be considerably easier to read and edit would be something more like the following example:
<?xml version="1.0"?>

I had written a "Pretty XML" script sometime around ten years ago that read an XML file, collapsed all of the whitespace between tags, and then inserted CRLF sequences and TAB characters in order to reformat the file. This script worked great for many years, but I decided that it would be more advantageous to use XSL to transform the XML. (e.g. "Why continue to do things the hard way when you really don't need to?");-]
With that in mind, I rewrote my old script as the following example:
' ****************************************
' MAKE PRETTY XML
' ****************************************
Option Explicit
Const strInputFile = "InputFile.xml"
Const strOutputFile = "OutputFile.xml"
' ****************************************
Dim objInputFile, objOutputFile, strXML
Dim objFSO : Set objFSO = WScript.CreateObject("Scripting.FileSystemObject")
Dim objXML : Set objXML = WScript.CreateObject("Msxml2.DOMDocument")
Dim objXSL : Set objXSL = WScript.CreateObject("Msxml2.DOMDocument")
' ****************************************
' Put whitespace between tags. (Required for XSL transformation.)
' ****************************************
Set objInputFile = objFSO.OpenTextFile(strInputFile,1,False,-2)
Set objOutputFile = objFSO.CreateTextFile(strOutputFile,True,False)
strXML = objInputFile.ReadAll
strXML = Replace(strXML,"><",">" & vbCrLf & "<")
objOutputFile.Write strXML
objInputFile.Close
objOutputFile.Close
' ****************************************
' Create an XSL stylesheet for transformation.
' ****************************************
Dim strStylesheet : strStylesheet = _
"<xsl:stylesheet version=""1.0"" xmlns:xsl=""http://www.w3.org/1999/XSL/Transform"">" & _
"<xsl:output method=""xml"" indent=""yes""/>" & _
"<xsl:template match=""/"">" & _
"<xsl:copy-of select="".""/>" & _
"</xsl:template>" & _
"</xsl:stylesheet>"
' ****************************************
' Transform the XML.
' ****************************************
objXSL.loadXML strStylesheet
objXML.load strOutputFile
objXML.transformNode objXSL
objXML.save strOutputFile
WScript.Quit
This script is really straightforward in what it does:
That's all that there is to it.
Note: For more information about the XSL stylesheet that I used, see http://www.w3.org/TR/xslt.
