>That does help. I modified my code by using your information and it is returning a 0. But how do I get to the key value?

If the function is returning a zero, then it means that it succeeded. Here's a code snippet retrieves the resolution width option from the VFP options

SET CLASSLIB TO REGISTRY.VCX ADDITIVE
oReg = CREATEOBJECT('Registry')
RELEASE CLASSLIB REGISTRY
lnvalue = 0
lcentry = "ResWidth"
lcpath = "Software\Microsoft\VisualFoxPro\6.0\Options"
IF oReg.GetKeyValue(lcentry, @lnvalue, lcpath, HKEY_CURRENT_USER) = 0
  ? lnvalue
ELSE
  * Error
ENDIF

Note the ampersand. That passes the variable by reference.
