>_<: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:
1 LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)
2 {
3 int i;
4
5 switch (message) //判断消息类型
6 {
7 case WM_TIMER: //时间消息
8 MyPaint(hdc);
9 break;
10 case WM_DESTROY: //处理窗口结束消息
11 DeleteDC(mdc);
12 ReleaseDC(hWnd,hdc);
13 for(i=0;i<12;i++)
14 DeleteObject(girl[i]);
15 KillTimer(hWnd,1);
16 PostQuitMessage(0);
17 break;
18 default:
19 return DefWindowProc(hWnd, message, wParam, lParam);
20 }
21 return 0;
22 }
>_<:And now function MyPaint(...) will be carryed out at
stated times.
