HBITMAP savewintodc(hwnd)

holdbmp = selectobject(hmemdc,hmembmp)
bitblt(hmemdc,...hwindc..)
selectobject(hmemdc,holdbmp)
return hmembmp;
}

HBITMAP Get(HWND hWnd)

HBITMAP hbm;
BITMAP bm;
RECT rect;
HDC memdc;

GetClientRect(hWnd, &rect);

hbm = CreateCompatibleBitmap(GetDC(hWnd), rect.right-rect.left, rect.bottom-rect.top);
memdc = CreateCompatibleDC(GetDC(hWnd));

HBITMAP h = (HBITMAP)SelectObject(memdc, hbm);

GetObject(hbm, sizeof(bm), &bm);
BitBlt(memdc, 0, 0, bm.bmWidth, bm.bmHeight, GetDC(hWnd), 0, 0, SRCCOPY);

SelectObject(memdc, h);

DelectDC(memdc);
}
