Abstract:
|
|
|
|
On Win9x, paint messages did not always cause WM_ERASEBKGND messages. This
|
|
is for applications that paint themselves before the WM_PAINT message and
|
|
then pass WM_PAINT onto the default handler.
|
|
|
|
Notes:
|
|
|
|
This is a general purpose shim, but should not be in a layer.
