Parameter from C++ to C#

[yatingg]

I have a C++ application that calls a C# COM. If the C++ passes the a CWnd to the C#, what object type is it in C#?

C++ app:

CWnd* pParentWnd;
MyObject myobject;

myobject->MyMethod(pParentWnd);



C# interface:
public interface MyObject
{
void MyMethod(????????);
}

What goes in the ?'s?

Thanks in advance!
