Hi,

I have hooked another application using a DLL. My application then
sends user defined messages to the target application which get caught
by the DLL which is loaded in the target applications address space.
I communicate the arguments that belong to a specific message
via shared memory.

F.e.:
My application sends a message to the hook DLL to return the value
of a specific cell in a TDBGrid in the target application. The argument
passed via shared memory is the handle of the TDBGrid.

Question:
How can the hook DLL get a pointer to the TDBGrid instance given
the window handle?

thanks for any idea,
Nick
