VBScript to detect if there is a COM+ application instance running

I had to figure out how to query the COM Administration catalog to detect if there is a specified COM+ application running.
Here is the quickly written vbscript:

running = False
Dim oCatalog
Set oCatalog = CreateObject("COMAdmin.COMAdminCatalog")
sName = "Tridion Content Manager"
Dim result
set apps = oCatalog.GetCollection("Applications")
apps.Populate

For Each app In apps
  If app.Name = sName Then
    Set objAppInst = apps.GetCollection("ApplicationInstances",app.Key)
    objAppInst.Populate
    for each inst in objAppInst
      pId = inst.Value("ProcessID")
      running = not ( inst.Value("IsPaused") or inst.Value("HasRecycled"))
      if running then
        Exit For
      end if
      Set objAppInst = nothing
    Next
    Exit For
  End If
Next
set apps = Nothing
set oCatalog = nothing
MsgBox pid & " " & running
