Hello. I have problems with an applications consisting of mixed

The application runs fine in "Debug mode", however when I compile

exception:

Does the problem occur when a debugger is attached? The information
you gave is from the point that the .NET framework catches the
exception and pretty low quality. With a debugger attached, you'll
trap the first-chance exception, at the point where the AV actually
occurs.

I run the program from within Visual Studio 2008 by clicking on "Start
debug". Is this what you mean? Then I can step through the code. When
I press F11 (Step Into) on the following code line, the exception
saying access violation appears immediately in the output window of
Visual Studio:
MeasureDialog = gcnew GcpsDialog();

even if I set a breakpoint on the first line of the constructor of
GcpsDialog. (A strange thing is that GcpsDialog is actually a part of
the main application and not a part of GcpsDotNetApi.dll - but the
dialog contains member variables that references into the DLL file -
so I guess this is the line of code that triggers loading of
GcpsDotNetApi.dll)

Turn on mixed debugging, and goto Debug menu > Exceptions and make sure that
Win32 exception "Access violation" is set to break when thrown.
