Hi there: Well, let me start off by saying that I am a Visual Studio drag
and drop weenie, not a real programmer. So I tend to get confused when
things do not look like the instructions said they were going to look :) .
Here is my current dilemma:
I am having a strange problem with my ASP.NET application. I am building the
application using Visual Basic .Net in Visual Studio.NET 2003. Lately, I
have frequently been getting the following exception (see below) when I
debug the application. If I step through my code and determine what is
actually broken (the exception is not very informative), I find that the
error has nothing whatsoever to do with the exception that is thrown. The
really, really strange thing is this: When I get this error, the "real"
exception always seems to be thrown from my code contained in a .vb class
file. If I create a new .vb file, and cut-and-paste the code into the new
file, delete the old file, and then re-run the application (with no actual
changes to the code whatsoever), then I get the "real" exception instead of
the "value cannot be null" exception. I have dozens and dozens of .vb class
files.. so far have gone through this process on about 10 files. This is
getting annoying. Has anyone experienced anything like this? I searched
newsgroups and ms knowledgebase, but I did not find anything resembling my
problem.
