The ValidateRect function validates the client area within a rectangle by removing the rectangle from the update region of the specified window.
BOOL ValidateRect(
HWND hWnd, |
// handle of window |
CONST RECT *lpRect |
// address of validation rectangle coordinates |
); |
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
The BeginPaint function automatically validates the entire client area. Neither the ValidateRect nor ValidateRgn function should be called if a portion of the update region must be validated before the next WM_PAINT message is generated.
Windows continues to generate WM_PAINT messages until the current update region is validated.
