How can I end a task that is currently running on my PC. For example when I press <Ctrl> + <Alt> + <Del> I see "winword.exe" in the Close Program dialog box. How can I end the task "winword.exe"?
Is there any function that takes the name of the task and then ends it?
There is a way but it's quite long and I don't have time to write it here:
every program has a HINSTANCE, this is a number that identifies the program; you find the proper HINSTANCE for the program you wanna close (that's the long part), and then use CloseHandle();

This works only if the window can be maximized/shown:
First, find the title of the window in the blue bar. Then, do this:
HWND find;
find = FindWindow(NULL, *Title of window here*);
SendMessage(find, WM_CLOSE, (LPARAM)0, (WPARAM)0);
Try that.
it would work, but what happens if the programmer meant to avoid this and handles the WM_CLOSE message?
Isn't there a function that finds the HINSTANCE out of a HWND?

Check out on MSDN a programme called TLIST !
It shows you the running tasks visible or invisible to ctrl+alt+del and shows you how to kill them !
It`s pretty simple but about 1000 lines of C code for functions on NT and 9.x !
I created a task manager and will soon be available on my website !
I`ll let you all know !
for the source code mail me ! and i`ll send it to you by mail !
tomkat rulez !:)
If you use spy to watch messages you'll see that when you use end task off of the taskmanager he sends a WM_CLOSE message when he shuts down an application.
After you wait some reasonable amount of time it the task is still running you can brut force it with TerminateProcess as a last resort.
