SharePoint Thoughts

When I was running through the Office Communications Server: Speech Server tutorial, Creating a Speech Project [found here], I ran into the following error, which plagued me throughout the runthrough.

Well apparently when creating the project, you were given the option to create custom Lexicons for your Grammar file. If you clear out these files, the solution will build, and you can use the voice response debugging window.

This happens because the MIME Type is not registered for .lex files in IIS, seen in KB938284.

RESOLUTION

To resolve this issue, follow these steps:

This solution was found using the MSDN Forums, quite a useful resource.

Patrick Tisseghem over at U2U suddenly passed away, and is sorely missed in all corners in the world. He was one of the first blogs I read when I was getting started with SharePoint. Very thoughtful, and I had hoped to meet him some day. Best wishes.

A link I don’t want to forget. Steve Graegert has a great post outlining the use of SPPropertyBag to make custom application pages to look like SharePoint application pages.
