Module Name:
DisableW2KOwnerDrawButtonStates.cpp
Abstract:
Hooks all application-defined window procedures and filters out new owner-draw buttons states (introduced in Win2000).
Notes:
This shim can be reused for other shims that require WindowProc hooking. Copy all APIHook_* functions and simply replace the code in WindowProcHook and DialogProcHook.
History:
11/01/1999 markder Created 02/15/1999 markder Reworked WndProc hooking mechanism so that it generically hooks all WndProcs for the process. 11/29/2000 andyseti Converted into GeneralPurpose shim.
