RemoveInvalidW2KWindowStyles.cpp
|
||
|
|
|
||
|
|
Abstract:
|
||
|
|
|
||
|
|
Windows 2000 deems certain previously supported Windows style bits as
|
||
|
|
"invalid". This shim removes the newly invalidated style bits from the mask
|
||
|
|
which will allow the CreateWindowEx call to succeed.
|
||
|
|
|
||
|
|
Notes:
|
||
|
|
|
||
|
|
This is a general purpose shim.
