Killing a process!

[Shark]

Does anyone knows how to kill a process in the task manager?

'this code taken from a Q & A Experts
'written by someone called: AzraSound
'
'make a new project
'add 4 commandbuttons and a listbox
'
'list all items running in task
'kill a specified task
' notice the listing of all handles and names in a
' listbox, you could easily add this to a 2D array
' instead, do a search for the name and then kill
' that process accordingly.


'this goes in a bas module

Thanks HeSaidJoe. This is what I am looking for, but it is kind of an overkill.

Just want to let you know two things.

First, you have the first command button on the form but there is no codes for it.

Second, Ending the task is not the same way how you would end from the Task Manager window. I am trying to close a program that is residue in the Task Manager Process Tab. Closing it from the Task Manager does not give me any other dialog box. Closing with your codes still does.

I am going to play around with it more and update back to you.

Thanks again HeSaidJoe...
