Here is a function I put together with LV and .net nodes it tool all of 2 minutes but still will list process handles and names of all processes on a system. I haven't had a chance to play with it but hope it helps. .Net allows some nice access to many of the stuff kernel and user32 used to do through dlls, but it is somewhat easier to find what you are looking for. I am still a newbie with the framework though. if you cant get the process ID's enumerated why don't you call kill process in a loop from 1 to 2^32 (This is not a serious suggestion).

You will need the .net 1.1 framework installed to run
code is in LV 7.0
