为什么不是间隔1S出来一张图片？怎么一下子全出来了？这是为什么呀？本人菜鸟，求指点！

case WM_PAINT:
        {
        hdc=BeginPaint(hwnd,&ps);
        Hdc=BeginPaint(hwnd,&ps);
        DrawIcon(hdc,people.x,people.y,Speople);
        DrawIcon(hdc,53,23,Apoint);
        DrawIcon(hdc,800,23,Bpoint);

        while (people.x<=800)
        {
        people.x=people.x+30;
        DrawIcon(hdc,people.x,people.y,Speople);
        SetTimer(hwnd,1,1000,NULL);
        }


你在这里已经是一次画出来了。你设置了定时器 ，不过你都没有用定时器，如果你要用定时器 就的响应WM_TIMER 消息。
启动计时器不应该WM_PAINT里面，在Create时候启动好点，如果在paint里面启动 ，最好就来个静态标记，启动一次吧。
,在比如,
 switch(uMsg)
    {
    case WM_CREATE:
       //SetTimer
    case WM_TIMER:
       //做你想做的事情， 比如更新界面的数据等。发送给跟新界面的消息就行了
    case WM_PAINT:
       //  更新界面
   

恩！多谢了！呵呵！刚学，还望多多照顾！
