Module Name:

|
ForceApplicationFocus.cpp
|
|
|
|
Abstract:
|
|
|
|
This shim calls SetForegroundWindow after CreateWindowEx and ShowWindow
|
|
calls to fix focus problems that applications tend to have when they
|
|
create/destroy windows on startup and manage to lose the foreground focus.
|
|
|
|
Notes:
|
|
|
|
This is a general purpose shim.
