errors in the inherited form design view

[David]

Using VS.NET 1.0, I encountered this error message when attempting to open
the design view of an inherited form.

************************************************
An error occurred while loading the document. Fix the error, and then try
loading the document again. The error message follows:

Value cannot be null.
Parameter name: path
************************************************

After frustrating hours of tracking down the problem, I upgraded to VS.NET
2003 and presto, the inherited form no longer shows that error message in
the design view.

Then about an hour later, the same error message shows up.

I have no clue as to why it is doing that. I don't have a parameter named
"path." Does anybody have any ideas?

Just an FYI, not that this will fix your problem, but we just got this
exact message today, albeit a different parameter name. Someone was doing
a Boolean.Parse(null) which threw this error. Basically they were trying
to parse a null value by mistake.

Now since you don't know what path is, that's the tricky part....have you
stepped through debug when it starts erroring out? What's the stack trace?
