>This is good but how do I get the cpu usage value?

Ah, I thought you wanted to know the process that were running. Wait me a second.

[Update]
Oops! Doh, now I understand the question, you want the CPU usage for each of the processes... I need to think that one

[Update 2]

Well, I can not continue looking for this, it seems as if I can get the Percentaje of CPU at a given time but not the actual value, I think you should use the Performance classes of WMI for this, but I never used them other that to see them, never looked into them, see if this helps

lparameters tcComputer, tcProcess
local lcComputer, loWMI, loProcess, loProcesses, lcProcess

lcComputer			= Iif(Vartype(tcComputer) = 'C' and not Empty(tcComputer), tcComputer, '.')
lcProcess			= Iif(Vartype(tcProcess) = 'C', tcProcess, '')
loLocator			= CREATEOBJECT('WBEMScripting.SWBEMLocator')
loWMI				= loLocator.ConnectServer(lcComputer)
loPerfDataCol			= loWMI.ExecQuery('Select * from Win32_PerfFormattedData_PerfProc_Process')
for each loPerfData in loPerfDataCol
	with loPerfData
			? .Caption, .CreatingProcessID, .Description, .PercentProcessorTime, .ElapsedTime, .Name
	endwith
endfor

To see more properties for this class go to http://msdn2.microsoft.com/en-us/library/aa394277.aspx

Also take a look at all the Win32_PerfFormatted* and Win32_PerfRaw* classes, you might find there what you need, it might even be that I am completely off mark
