Using graphical ActiveX (COM) controls in WinForms project

I have a collection (set) of ActiveX controls. I开发者_JAVA技巧 recieved them from our vendor company.

I created a wrappers for them using tlbimp.exe and aximp.exe.

All non-graphical controls work good.

All graphical controls don't react on some methods. When I call their methods I get:

TargetInvocativeException (InnerException is null). or Attempt to read/write protected memory.

Our vendor company assure that their graphical activex controls work good. But they don't provide support service, so I have to find solution of my problem alone.

And some more,

All graphical activex controls don't react on mouseclick or any other mouse manipulations. But documentation says: it must change the color on mouse click.

Maybe, someone have same symptoms and can help me ! I googled over that problem many pages but they don't help me.

Maybe it's some Visual Studio settings or compiler options ? I use VS 2005.


Does it work at all? Try ActiveX Control Test Container (tstcon32.exe) .
