Hi iceman, Do you have a C/C++ related question? I fail to see how your question applies to the board topic. Best Wishes, -David Delaune

No. The process will not get any clue when it is terminated from the taskmanager.

Hi Naveen, Are you sure about that? The task manager uses two methods of terminating an application depending on which tab is selected. One of them can be ignored by an application. Best Wishes, -David Delaune

Hi David, I mean the "EndProcess" option in the "Process" tab of the task manager( I guess it uses TerminateProcess()). It is the "End task" option in the "Application" tab that can be igonred( which sends a WM_CLOSE message ). right? Please correct me if I am wrong.

Yes, the 'End Task' button on the 'Application' tab simply sends a WM_CLOSE message. You can see this with the Spy++ utility. An application or malware could potentially ignore this message. Best Wishes, -David Delaune

I believe so - I think the window gets a WM_CLOSE or WM_QUIT first (can't remember which) and if it doesn't die pretty quickly, it then gets terminated with TerminateProcess. I think that's how it works, anyway.

Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p

Simply see the Taskmgr.exe source code (C, Win32 group[^])
