今天在MSN的核心讨论组上看到两篇文章.讨论的乃是应用程序是否没有响应.原文如下:
How is it possible to determine a process is "not responding" like NT Task
Manager do？
The heuristic works only for GUI processes, and consists of calling
SendMessageTimeOut() with SMTO_ABORTIFHUNG.
There is any API call to do the job, or this status is simply a deduction
（本文来源于图老师网站，更多请访问http://www.tulaoshi.com/bianchengyuyan/）based on process counters, like that returned from call to GetProcessTimes
API function？
Use SendMessageTimeout with a value of WM_NULL. That's all Task
Manager does to determine this AFAIK.

有理有理.当然,我这里还有一个UNDOCUMENTED函数,乃是其他的解决方案,NT和9X有个USER32.DLL的函数,IsHungAppWindow(NT)和IsHungThread(9X).使用起来简便无比.下面给出原型.
（本文来源于图老师网站，更多请访问http://www.tulaoshi.com/bianchengyuyan/）BOOL IsHungAppWindow (
HWND hWnd, // handle to main app's window
);
BOOL IsHungThread (
DWORD dwThreadId, // The thread's identifier of the main app's window
);
有了原型,连解释都不需要,好得不的了.:)不过调用时需要GetProcAddress.库里没有该函数.
