如何让窗口停放在桌面的右下角

MoveToBottom()
{

CRect rcDesktop,rcWin,rc;

SystemParametersInfo(SPI_GETWORKAREA,0,&rcDesktop,0);	//获取桌面大小

GetWindowRect(rcWin);				//获得自身大小
CPoint lefttop,rightbottom;

lefttop.SetPoint(rcDesktop.Width() - rcWin.Width(),rcDesktop.Height() - rcWin.Height());
rightbottom.SetPoint(rcDesktop.BottomRight().x,rcDesktop.BottomRight().y);
rc.SetRect(lefttop,rightbottom);

MoveWindow(&rc );

}
