Are Word/Excel Running?

Can anybody please give me the code for the following;

I want to know if MS Word is running.
I want to know if MS Excel is running.

Thanks,

Graham.

Dim nHandle As Long

' If Excel is running this API call returns its handle.
nHandle = FindWindow("XLMAIN", 0) 'use "WINWORD" for Word

If nHandle = 0 Then ' 0 means Excel not running.
'do something here
End If

Thanks for the code but can I confirm..

Is 'FindWindow' a VB command or is it a C+ command as I am getting a Sub or Function not defined.

Thanks
Graham.

FindWindow is part of the Windows API:

Declare Function FindWindow Lib "user32" Alias _
"FindWindowA" (ByVal lpClassName As String, _
ByVal lpWindowName As Long) As Long
