I've been developing an application for the past year and a half in VB.NET, i was close to finishing and I've run into this problem. First, the exception was triggered when i used dataset.tables(0).select("date=#2/1/04#", "date DESC")which was working fine before. I temporarily changed it to simply select() with no arguments and the code continnued to run and it got to another function and the same exception showed. Everything causes this exception. What does this mean??? How can I fix it, Other than this problem, I am ready to deploy the app so I really need to fix this.
