ScreenToClient (Windows Embedded CE 6.0)
1/6/2010
This function converts the screen coordinates of a specified point on the screen to client coordinates.
Syntax
BOOL ScreenToClient(
HWND hWnd,
LPPOINT lpPoint
);
Parameters
- hWnd
Handle to the window whose client area will be used for the conversion.
- lpPoint
Long pointer to a POINT structure that contains the screen coordinates to be converted.
Return Value
Nonzero indicates success. Zero indicates failure.
To get extended error information, call GetLastError.
Remarks
The function uses the window identified by the hWnd parameter and the screen coordinates given in the POINT structure to compute client coordinates. It then replaces the screen coordinates with the client coordinates.
The ScreenToClient function assumes the specified point is in screen coordinates.
All coordinates are in device units.
Regardless of the screen's layout settings, ScreenToClient always interprets coordinates as if the screen layout is left-to-right. Do not use this function if your screen has a right-to-left layout. Instead, use MapWindowPoints.
