Support ends for Visual Basic 6

Posted by Vijay on April 29, 2008 Comments Off

Microsoft officially ended support for Visual Basic 6 this month.  This is a massive blow to any organisation still running their business using legacy applications.

Now might be a good time to start afresh, and replace those applications using Domain Driven Design and TrueView.
