dwError = ::GetLastError()
hBitmap = ::LoadBitmap( g_hInstance, MAKEINTRESOURCE( IDB_BITMAP1 ))
dwError = ::GetLastError()
hPrevObj = ::SelectObject( hDCMem, hBitmap )
dwError = ::GetLastError()
hPrevObj1 = ::SelectObject( hDCMem, g_hPen )
dwError = ::GetLastError()
BOOL bStat = MoveToEx( hDCMem, g_X, g_Y,&g_Point )
bStat = ::LineTo( hDCMem, g_X, g_Y+1 )
dwError = ::GetLastError()
bStat = ::BitBlt( hDC, 0,0, 240,82,hDCMem, 0,0, SRCCOPY )
