Arrgh. Still grinding my teeth. What I am trying to do is get the GUID of a COM object so I can explore it programatically. So I make the WMI call to read the Registry for it, but there is no value name. So my code is still exploding.

#include registry.h
Local cRetVal as String
Clear
oRegRead = GetObject("winmgmts:{impersonationLevel=impersonate}!\\.\root\default:StdRegProv")
cKeyPath = "dataproc.processor\CLSID"
iErrNo = oRegRead.GetStringValue( HKEY_CLASSES_ROOT, cKeyPath , , @cRetVal )
? cKeyPath
? cRetVal
? iErrNo

It explodes I think on the value between cKeyPath and @cRetVal. I have tried putting in .Null. , Chr(0) , "" , " ", and ,, and it always blows up. How to address that?

Thanks.
