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.
|
