OpenNetCF - Killing Local Processes

Hi All

I've been looking at the OpenNetCF and it's Process Class - I see lots
of ways to start and control a process, but is there a way to kill a
process that was not started by you? By that, I mean that you don't
have a ProcessID, so GetProcessByID is out and there doesn't seemt to be
a way to get an ID from an application/window title.

Anyone have any suggestions?


Many thanks

You can enumerate all of the processes in the system with toolhelp
functions. I don't know what portion of those might be implemented in SDF,
but I think at least one or two were.

Don't forget that calling TerminateProcess is a very, very serious matter
and should be done only as a final resort, expecting the system to be left
in a semi-stable state.

My requirement is that I need to shut down another of my own
applications - there must not be any need for user intervention.
Basicly, I want to do programaticly the same as going into Running
Programs in Settings on a PPC.
Thanks for the info and I accept your warnings, but at present it's the
only way I can find to do what I need.


Many thanks

Just a thought. If it is one of your own, why not tell it (e.g. with a named
event) to shut down itself?

You can do that by having a know way of sending a message to that
application, in response to which it can just exit. Use
RegisterWindowMessage() with the same message name in both applications.
When the message arrives in the one to be exited, exit it! Send it using
SendMessage( HWND_BROADCAST, ... ) from the other one. There is
*absolutely, positively* no good reason why you should have to use
TerminateProcess on a program for which you have the source and know that
you'll need to cause an exit from.

Errr... sure... you can only utilize a method if you know about it and
I've not had a need to do anything like this before.

I now do but there's no need to give your self an ulcer over it - there
are far more important things in the world to do that.

Thanks for the heads up, I'll be looking into it Monday.

If you want to emulate the functionality of the running programs applet you
can send a WM_CLOSE message to your specific window (rather than
broadcasting a special message), you can use FindWindow to determine the
windowhandle of your application from its window caption. This is how the
control panel applet closes applications.

I'm not sure where you're coming from. All I did was give you a possible
solution and strongly discourage you from using TerminateProcess.
