个人改编自原书源代码，想做成“打地鼠”的游戏，各位编译下就知道了。运行就可以发现问题。麻烦各位了，谢谢！

单步调试，现在忙
晚上帮你看看

楼上的朋友，你的代码只加了一句：#include<time.h>吧，没有什么作用啊

[猪头小哥]

哥们，你工程没建错？win32项目（vs2010）我这有警告 但是没错误啊，运行的时候有个叉叉在动~~

还得改：
点“项目(V)”->最底下的那个“xxxxx 属性”
左边展开“配置属性”，点“常规”
把右边倒数第三个的“使用 Unicode 字符集”修改成“使用多字节字符集”，点确定
现在可以点上面的绿色三角形开始编译调试了，然后就运行起来产生一个窗口了。
注意一下，如果你把编译模式“Debug”改成“Release”，是还要设置一次字符集的，因为这两种编译模式的设置都是分开的。

TextOut(hdc,10,10,szBuffer,wsprintf(szBuffer,TEXT("hit is :%d"),nHit));
TCHAR szBuffer[59];
你都没看到我改了一些语句。

[Quote=引用 7 楼 的回复:]

TextOut(hdc,10,10,szBuffer,wsprintf(szBuffer,TEXT("hit is :%d"),nHit));
TCHAR szBuffer[59];
你都没看到我改了一些语句。
[/Quote]真是十分抱歉，的确没有看出你所做的修改，对不起。
但是，您所提供的代码经过编译后任然不能正常刷新，也就是说那个X仍旧会卡住。和我之前遇到的问题一样，不知道您是否自己编译运行过。
