convert class instance to IntPtr

[swartzbill2000@yahoo.com]

I want to PostMessage from a class instance to its containing form. I
want the WPARAM to point to the class instance. I am using the
declaration of PostMessage from www.pinvoke.net. WPARAM is an IntPtr.
VB2005 won't let me do this:
CType(Me, IntPtr)
How can I pass Me as the WPARAM arg?

Might be able to use System.Runtime. InteropServices .Marshal methods to get
the interface you need.

Maybe Marshal.GetIDis patchForObject?

I found GCHandle. It works.
