Creating an HTML Application to Convert Text Files to Audio Files
27 May 2015 • by Bob • HTMLA, Scripting, VBScript
I'd like to take a brief departure from my normal collage of web-related and server-management examples and share a rather eclectic code sample.
Here's the scenario: I am presently working on another college degree, and I was recently taking a class which required a great deal of reading. These assignments were all in digital form: I was using PDF or Kindle-based versions of the textbooks, and the remaining reading consisted of online articles. However, I am also an avid bicyclist, and the voluminous amount of reading was preventing me from going on some of my normal weekly rides. This gave me an idea: if I could convert the digital text to audio, I could bring my assignments with me on my longer rides and have my MP3 player read my assignments to me as I pedaled my way around the Arizona deserts.
I had experimented with Microsoft's built-in text-to-speech features some years ago, so I thought that this would be the perfect opportunity to revisit some of those APIs and write a full application to do the conversions for me. That being said, I could have written this application by using C# (which is my preferred language), but I decided to create an HTML Application for two reasons: 1) it is easier for me to share HTMLA applications in a blog, and 2) I keep this application in my OneDrive, so it's easier for me to modify the source code on systems where I don't have Visual Studio installed.
With that in mind, here is the resulting script which will convert a Text File to a Wave (*.WAV) File.
Using the HTML Application
As with most of my HTML Applications, the user interface is pretty simple to use; when you double click the HTA file, it will present you with the following user interface:
Clicking the Browse button will obviously allow you to browse to a text file, clicking the Close button will close the application, and clicking the Write File button will create a Wave file that is in the same path as the source text file. For example, if you have a text file at "C:\Text\Test.txt", the script will create a Wave file at "C:\Text\Test.txt.wav".
That being said, there are a few options which you can set:
- Depending on your version of Windows and which languages you have installed, you will be presented with a list of available voices in the first drop-down menu; the following example is from a Windows 8 computer:
- The second drop-down menu allows you to vary the playback speed; sometimes I prefer the playback speed to be slighter faster than normal:
- The third drop-down menu allows you to alter the volume of the resulting Wave file:
Note: You can modify the script to alter the values that are used in the playback speed and volume drop-down menus, but the list of voices is obtained dynamically from your operating system.
Creating the HTML Application
To create this HTML Application, save the following HTMLA code as "Text to Wave File.hta" to your computer, and then double-click its icon to run the application. (Note that in a few places I added code comments which contain the MSDN URL for the APIs that I am using for this sample.)

Note that I intentionally chose to have this HTML Application convert the text to audio one line at a time; this slows the down the conversion process, but it allows the conversion to be cancelled if necessary. (My original version of this script would convert an entire text file at one time; since there was no way to cancel the operation, the script appeared to hang when converting larger text files.)
Additional Notes
Once you have created a Wave (*.WAV) file, you can optionally convert it to an MP3 file for use in an MP3 player or mobile phone. (Most devices should playback Wave files, but MP3 files are considerably smaller and more portable.) There are a variety of Wave-to-MP3 converters out there, but I prefer to use the LAME encoder, which is an open-source code project that is available on SourceForge. Once you have the LAME encoder project compiled, (or you have located and downloaded a pre-compiled version), you can use LAME.EXE from a command prompt to convert your Wave files into MP3 files.
That being said, I prefer to automate as much as possible, so I have written a batch file which converts all of the Wave files in a directory to MP3 files and renames the source Wave files with a "*.old" filename extension:
@echo off for /f "usebackq delims=|" %%a in (`dir /b *.wav`) do ( for %%b in (^"%%a^") do ( if not exist "%%~db%%~pb%%~nb.mp3" ( lame.exe -b 128 -m j "%%a" "%%~nb.mp3" ) if exist "%%~db%%~pb%%~nb.mp3" ( move "%%a" "%%a.old" ) ) )
Note that the above batch file was written for text-to-speech use, and as such it defines a bit rate of 128kbps, which would be pretty low for music files. If you want to repurpose this batch file for higher bitrates, modify the value of the "-b" parameter for the LAME.EXE command.
That wraps it up for today's post.

Updating my HTML Application for Configuring your WebDAV Redirector Settings
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.)

Additional Notes
As with the last version of this HTML Application, you will need to run this application as an administrator in order to save the settings to the registry and restart the WebDAV Redirector service.
Have fun! ;-]

How to create an HTML Application to configure your WebDAV Redirector settings
07 October 2011 • by Bob • IIS, Scripting, WebDAV
I've mentioned in previous blog posts that I use the Windows WebDAV Redirector a lot. (And believe me, I use it a lot.) Having said that, there are a lot of registry settings that control how the Windows WebDAV Redirector operates, and I tend to tweak those settings fairly often.
I documented all of those registry settings in my Using the WebDAV Redirector walkthrough, but unfortunately there isn't a built-in interface for managing the settings. With that in mind, I decided to write my own user interface.
I knew that it would be pretty simple to create a basic Windows Form application that does everything, but my trouble is that I would want to share the code in a blog, and the steps create a Windows application are probably more than I would want to write in such a short space. So I decided to reach into my scripting past and create an HTML Application for Windows that configures all of the Windows WebDAV Redirector settings.
It should be noted, like everything else these days, that this code is provided as-is. ;-]
Using the HTML Application
When you run the application, it will present you with the following user interface, which allows you to configure most of the useful Windows WebDAV Redirector settings:
Creating the HTML Application
To create this HTML Application, save the following HTMLA code as "WebDAV Redirector Settings.hta" to your computer, and then double-click its icon to run the application.

Additional Notes
You will need to run this HTML Application as an administrator in order to save the settings and restart the Windows WebDAV Redirector. (Which is listed as the "WebClient" service in your Administrative Tools.)
This HTML Application performs basic validation for the numeric fields, and it prevents you from exiting the application when you have unsaved changes, but apart from that there's not much functionality other than setting and retrieving the registry values. How else can you get away with posting an application in a blog with only 500 lines of code and no compilation required? ;-]
