I have a large project where we have 2-3 dll projects that are converted from VB6 to VB.NET. We have fixed all the issues that caused compilation errors, and most of obvious issues in running, so now we have basically a program up and running. The exe is created from scratch in VB.NET, using a lot of functionality from the converted dll’s (including GUI forms).
OK, so far so good. What I wonder is when I run the program in debug mode, I get a bunch of warnings in the “Immediate Window” saying:
A first chance exception of type 'System.Exception' occurred in Microsoft.VisualBasic.dll
…and some of other type (but most of them in Microsoft.VisualBasic.dll).
I was wondering if this is common in projects converted from VB6, or if it is caused by bad design in our code…
It’s not limited to converted projects.
