为什么我的程序运行一段时间就停止响应了

是用API编的类似按键精灵的东西！没多少数据的!

用什么api，win32的吗、
有没有用到多线程，发生了死锁现象。

TO： Mangkee(阿诺)
开始可以运行的，死锁的可能不大吧~TO：top1000(天天向上)
你所说的异常都包括什么呢！TO：njbaige(白鸽)
开始运行是都很正常，大概一个小时后就不会动了，去任务管理器看的时候，已经停止响应了！初次做东西，还请各位帮忙，赐教！谢了!

TO：njbaige(白鸽) 类似按健精灵的东西，在浩方发广告的！

}麻烦了~

初步看了你的程序，以前也没有怎么做到过这种类型的，
好像你是调用了user32.dll 中的函数，做底层的Win32 操作，在线程中调试错误不是很方便
（有错了也反映不出来），你可以先将线程取消调，直接通过一个方法，运行，那样出错在
什么地方，提示信息也会有的，在方法中调试OK 了，再放到线程中去关键是你的方法BackgroundProcess 中会出问题这个只是我的看法了，也帮不上多少忙，见凉～～

非得调用extern dll吗？我对vc不熟悉看不懂。
汗颜……
不过看你用到了线程，应该是这里出的问题。慢慢调试一下吧。
一部分一部分的调试。
不要整个程序调试。

调试易

为什么我的程序运行一段时间就停止响应了
