I have got an Interface method that takes a void*. Dot Net interprets it as a
System.IntPtr structure. I now want to pass a COM interface reference through
the IntPtr type. How can i achieve this???

If you are trying to pass a interface reference that lies witihn an object,
you can try this, i use this:

//This class implements the interface
MyServerObject SO = new MyServerObject ();

//Get the pointer to our class
IntPtr ObjectPtr = Marshal.GetIUnknownForObject(SO);

Then you can return the ObjectPtr.
