ComptonsBible.cpp

Abstract:
|
||
|
|
|
||
|
|
This shim checks to see if Compton's Interactive Bible is calling DdeClientTransaction to create
|
||
|
|
a program group in the Start Menu for America Online. If so, NULL is passed as pData to prevent
|
||
|
|
the application from doing anything with the program group, i.e. CreateGroup or ShowGroup.
|
||
|
|
|
||
|
|
Notes:
|
||
|
|
|
||
|
|
This is an app specific shim.
