How To End Process Tree

[SVogt83]

Is there a way in VB.NET to mimic the "End Process Tree" option found
in the task manager? I have searched the process class and can not
find any way to determine a relationship between any two processes.
Is it possible to stop a process and all its "children" in VB.NET?

Incase anyone else has his problem, i have finaly found code to solve
it for my purposes. If you have a process already handled in your
program, and have its ID, then you can loop though all processes using
the process class and send the ID ov each process to
GetParentProcessID. If the ID of your process matches the returned ID
then you can kill it. If anyone happens to read this and spots a
problem please let me know. Thanks
