[RESOLVED] Test if argument is part of enumaration

[penagate]

Thanks to both of you, I hoped there was an way to compare to them all at once. but that seems to be wishfull thinking.

Sure there is!

Public Enum EnumBaseKeys
    [_ENUMBASEKEYS_FIRST] = &H80000000
    HKEY_CLASSES_ROOT = &H80000000
    HKEY_CURRENT_USER = &H80000001
    HKEY_LOCAL_MACHINE = &H80000002
    HKEY_USERS = &H80000003
    [_ENUMBASEKEYS_LAST] = &H80000003
End Enum
 
' .......
 
Public Function Makekey(Optional Hkey As EnumBaseKeys, Optional Subkey As String) As Boolean
    If ((Hkey >= [_ENUMBASEKEYS_FIRST]) And (Hkey <= [_ENUMBASEKEYS_LAST]) Then
        ' ...
    End If
End Function

The brackets around the FIRST and LAST members hide them from the Intellisense menu, so you won't accidentally use them when assigning values
