Hi Vsevolod,


Gah!  Good grief.  Thanks for seeing what I missed.


###
def queryForValue(reg, name, defaultValue=""):
    try:
        values = QueryValueEx(reg, name)
        return values[0]
    except WindowsError:
        print "Error:", name, "string missing from registry:",
        print "creating default value:", defaultValue
        nothing = SetValueEx(reg, name, 0, REG_SZ, defaultValue)
        return defaultValue

Thank you again; good catch.  Why is programming so hard?  *grin*
