window SDK 在按钮控件 BUTTON 上使用图片

        BS_hwnd = CreateWindow ( TEXT("BUTTON"), 
            L"bitmap1",
            WS_CHILD | WS_VISIBLE | BS_BITMAP,//须设为BS_BITMAP
            10, 10,
            120,40,
            hwnd, (HMENU) 1,
            ((LPCREATESTRUCT) lParam)->hInstance, NULL) ;
        SendMessage(BS_hwnd,   
            BM_SETIMAGE, //须设为BM_SETIMAGE
            (WPARAM) 0, 
            (LPARAM) LoadImage ( 0,  L"C:\\1.bmp", IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE )//须将图片句柄转为(LPARAM)
            );
