请问SDK编程怎样使用BS_ICON,BS_IMAGE来设置按钮？

Question

本人初学《windows程序设计》，里面关于这方面蜻蜓点水，希望高手指教！

Answer 1

只知道这两个是CreateWindow()的参数，但是具体的使用就不知道了

Answer 2

hwndButton = CreateWindow(
                  "BUTTON",   // predefined class
                  "OK",       // button text
                  WS_VISIBLE | WS_CHILD | BS_DEFPUSHBUTTON|BS_ICON,//styles
               // Size and position values are given explicitly, because
               // the CW_USEDEFAULT constant gives zero values for buttons.                   5, // starting x position
                   5, // starting y position
                  30, // button width
                  18, // button height
                  hWnd,   // parent window
                  NULL,   // No menu
                  (HINSTANCE) GetWindowLong(hWnd,GWL_HINSTANCE),
                  NULL);      // pointer not needed // load the icon, NOTE: you should delete it after assigning it.
 hIcon = LoadIcon(hInst,MAKEINTRESOURCE(IDI_ICON1));
 // associate the icon with the button.
 SendMessage(hwndButton,BM_SETIMAGE,(WPARAM)IMAGE_ICON,
            (LPARAM)(HANDLE)hIcon);
