DragDrop registration failed

Hi there,

I tried to use Go Diagram using C++ .NET 2003.

I created a simple program to add GoView to main form.

When I ran the program an error message appear:

An unhandled exception of type ‘System.InvalidOperationException’ occurred in system.windows.forms.dll

Additional information: DragDrop registration failed.

FYI, applying the [STAThread] attribute to the main()

entry point in my managed C++ application does not

seem to have any effect.

any ideas?


No, I don’t. I know that I and various customers have gotten managed C++ applications to work, though, so it isn’t an inherent problem.
