<br>内容：&nbsp;&nbsp;SaveDC Saves the current state of the device context by copying state information (such as clipping region, selected objects, and mapping mode) to a context stack maintained by Windows.<BR>&nbsp;&nbsp;The saved device context can later be restored by using RestoreDC.<BR><BR><BR><BR>
