Using vmware-cmd for scripting on Windows hosts: what does it return?

Hello,

I'm trying to write an easy to use script for the backup purposes; I use WSH for it. I'd like to use the vmware-cmd for getting the state of my VMs, therefore I would like to know, what does the vmware-cmd return...

The following does not work:

Set wshshell = CreateObject("Wscript.Shell")

comstring = "vmware-cmd " & myVM_vmxFile & " getheartbeat"

result = wshshell.run(comstring,0)

msgBox result

/code

The msgBox shows always a null; it doesn't matter which heartbeat the VM currently has...

What I'm missing?
