WIN 2003对虚拟DOS的支持不够好。要跑DOS程序还得改一些地方，这个页面里有，你看看行不（里面介绍的是WIN 2000《我在Windows 2000下运行用NEO编译的DOS程序，但发现无法运行里面的实例，为什么？》）：

董哥 帮我写个WINDOWS下的动画程序呗！
我写这个不是即时的那种！

[CODE]#include <windows.h>
#include <math.h>
#define PI 3.14
int cxClient, cyClient ;
float i, j, x, y ;
LRESULT CALLBACK WndProc (HWND, UINT, WPARAM, LPARAM) ;

Timer方面的API不难，稍微查点资料就可以完成。
我现在在公司赶工~~~命苦哇

我就是用TIMER事件
但是没弄出来

关键是重画问题
我不知道用什么好办法记录已经画的图形

点少的话用数组，这个点这么多……
话说真的很漂亮！顶一下

五体投地

我滴神啊！
