В былые времена помогли этому классу я использую файлы INI с моими программами VB6:
VERSION 1.0 CLASS
BEGIN
MultiUse = -1 'True

Attribute VB_Name = "cInifile"

' Class: cIniFile
' Author: Steve McMahon
' Date : 21 Feb 1997
'
' A nice class wrapper around the INIFile functions
' Allows searching,deletion,modification and addition
' of Keys or Values.
'
' Updated 10 May 1998 for VB5.
' * Added EnumerateAllSections method
' * Added Load and Save form position methods
