The UpdateWindow function updates the client area of the specified window by sending a WM_PAINT message to the window if the window's update region is not empty. The
function sends a WM_PAINT message directly to the window procedure of the specified
window, bypassing the application queue. If the update region is empty, no
message is sent.
BOOL UpdateWindow(
HWND hWnd
| // handle of window
| );
|
|
Parameters
hWnd
Identifies the window to be updated.
Return Values
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero.
