<b>肯定一个利用程序能否没有呼应</b>[VC/C++编程]

本日在MSN的核心谈论组上看到两篇文章.谈论的乃是利用程序能否没有呼应.原文以下:

> 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

>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,乃是其他的办理筹划,NT和9X有个USER32.DLL的函数,IsHungAppWindow(NT)和IsHungThread(9X).利用起来简便非常.下面给出原型.

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,连注释都不需求,好得不的了.:)不过调用时需求GetProcAddress.库里没有该函数.
