Showing a form in a COM visible DLL

From unmanaged VC++ 6.0 I'm calling a COM visible .NET DLL. From this DLL, I want to show a dialog. I can get the DLL to register properly and work if the methods don't call However, if the methods DO call form show, I cannot instantiate the DLL (I get 'class not registered error").

Anybody know what I need to do?

Pretty unclear, you'd have to create the COM object instance antes you could call the Show() method. Threading issues are associated with "class not registered" errors, make sure you C++ thread is STA. -

Assuming that's a Windows Forms Form.Show(), I think you'll need a Windows Forms Application.Run() in your process somewhere.
