Hi I'm a C# .NET newbie doing a minor school project but I'm getting a
strange error message.
'System.NullRef erenceException ' occurred in system.windows. forms.dll
Additional information: Object reference not set to an instance of an
object."
As my references look I seem to be using the old framework(1.0.3 705) for
this, but re-referencing to the newer framework(1.1.4 322) dll's produces the
same error. This happens under all circumstances when I'm trying to compile
a fully managed project. Even from scratch when trying to just compile the
empty form this happens.
If you read the old thread I've included you can see that he changed his
sourcepath for the whole project to something that is not put in the
MyDocuments folders. I did exactly the same thing and it worked, the
question from me is WHY? All other apps (so far) compiles flawless, it's
only these C# Windows Applications Projects that fail.

Andreas Wirén
