>_<:This time we will study a new way to operate your picture.That is running your picture by give it a timer-message.

>_<:Firstly,you should use the function SetTimer(hWnd,1,50,NULL) to create and set a timer (here "1" means the timer is number 1,you can understand it as the timer's name; "50" means frequency)

>_<:Then only need to add timer-message listener in  WndProc(...) function:

 LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)

 {

     int i;

     switch (message)                   //判断消息类型

     {

         case WM_TIMER:                //时间消息

             MyPaint(hdc);

             break;

         case WM_DESTROY:              //处理窗口结束消息

             DeleteDC(mdc);

             ReleaseDC(hWnd,hdc);

             for(i=;i<;i++)

                 DeleteObject(girl[i]);

             KillTimer(hWnd,);

             PostQuitMessage();

             break;

         default:

             return DefWindowProc(hWnd, message, wParam, lParam);

    }

    return ;

 }

>_<:And now function MyPaint(...) will be carryed out at stated times.
