HBITMAP hbm = (HBITMAP) LoadImage(NULL, "LePathDeTonImage", IMAGE_BITMAP, /*Sa Width*/, /*Sa Height*/, LR_LOADFROMFILE | LR_CREATEDIBSECTION);
HDC hdcImage = CreateCompatibleDC(NULL);
SelectObject(hdcImage, hbm);
StretchBlt(hdc, 0, 0, /*Sa Width*/, /*Sa Height*/, hdcImage, 0, 0, /*Sa Width*/, /*Sa Height*/, SRCCOPY);
