The OffsetWindowOrgEx function modifies the window origin for a device context using the specified horizontal and vertical offsets.
BOOL OffsetWindowOrgEx(
| HDC hdc, | // handle to device context | 
| int nXOffset, | // horizontal offset | 
| int nYOffset, | // vertical offset | 
| LPPOINT lpPoint | // pointer to structure receiving the original origin | 
| ); | 
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.
