can you put a pointer or anything into a window handle, or have something sent to the messageproc? i'm writing a wrapper over the window functions and i just want the message proc to be able to get a pointer to the wrapper class... any suggestions? Thanks, Axi.

Yes you can. The usual way is to use GetWindowLong()/GetWindowLongPtr() with the GWL_USERDATA flag. Generally you set the data in the WM_NCCREATE handler for the class using SetWindowLong()/SetWindowLongPtr() using the LPCREATESTRUCT data.
