Detecting and Killing a process in Windows

[McV]

I have looked at the utilities posted in Winevent.llb (from lvwinutil.zip in a previous discussion thread from way back in LabView 4!)

The TaskList function works fine, but there is a missing .vi "PostMessage Master.vi" in "Quit Application.vi"

Does anyone know where this is hiding?

Alternatively, is there another (better?) way of achieving this?

I need to detect the presence of a task and terminate it if found........

If the method will work on Windows 2000 AND XP, so much the better.

Ta....

I have lvwutil library (though I don't use it), so I can verify that VI is in the WINUTIL.llb file. You may want to download the lvwutil library again from NI.

Thanks - found it.

I am also trying SystemExec.vi and calling the taskkill.exe directly -seems I can make it work both ways.

Now comes the trick - make it robust! - Cheers........

I don't know how much more (or less) robust this would be, but you could also utilize the call library function node.  With Kernel32.dll, using the "TerminateProcess" function.

I don't know the 'find all processes' function offhand but I know it's in there.

Just an idea!

Surprise, surprise, I'd recommend using .NET - much easier to work with in LabVIEW than Win32 - as long as you have LabVIEW 7.1 or later.

If you don't have it already, install .NET 2.0 or .NET 3.0 (just released).

Go to examples\comm\dotnet\SimpleTaskMonitor.llb and take a look. It's a large example, so don't get overwhelmed - but you should be able to pull out the basics on how to get the list of running processes via .NET. Then the Process object has a Kill() method you can use.
