>But, in VB.NET, this is a complete disaster. I ended with another discovered bug in production a few days ago from something that was all set for years. A few months ago, I changed a line way higher in the code, then, it decided to case sensitive thousands of lines below, those who contained quotes, and guess what, in those, I had javascript code. As you know. javascript code is case sensitive and that created a bug in production. We had horor stories like these at three more occasions. So, administration wants to shut down further development until we fix the problem or go back to previous setup, which will take me a lot of time. IAC, at one point or another, we would still to move forward. So, I need to fix this.

>Note also that this is just not about case sensitivity. It will auto format the rest of the code as it sees fit. So, I have seen space insertions in lines such as lcHtml = lcHtml + "Something" where the inside quote portion ended with HTML tags now containing a space after the opening tag character and this broke the HTML page. Select command also have been changed making SQL select queries to bug. But, all that, you cannot see it. You only discover that weeks and months later.

Did you make a MS Connect bug report when you discovered that problem? Can you provide a link to vote?

I don't use VB.NET so I can not test for you although I may ask your question at MSDN forum for VB.NET Users if you'd like.
