Form to control .ini or .dat file

I am going to create a .dat file or .ini file to hold information such as...
Line  cmdName    Caption     Password      Visible       Pwd

Line will be the line number
cmd Name will be the name of the command button
Caption will be a user definable caption for the command button
Password will be the password to access the shelled program
Visible will be a flag to determine if this button is visible or not.
Pwd will be a flag telling whether this button is password protected or not.

Now to keep the user from having to go in and modify the .dat file I want to create a form that the user can modify (only) these items in the columns and rows.
What is my best way of doing this task?

PS..Using VB4 16 bit

You should use INI file and do the structure as follow :
[Line] = Section
cmdName=...
Caption=...    
Password=...      
Visible=...      
Pwd=...

It sill easier for you to handle it.

To finish, if you need sources to read INI filer under 16 bits, I will send them to you.

By the way, here is the code to read under 32 bits, you could convert the API to 16 bits using your API viewer :
Option Explicit

I really don't want to use an .ini file. There is over 100 entries with a Line, cmdName, Caption, Password ,Visible and Pwd
section for each. I also would not prefer creating a grid and populate it an .ini file. What I really want is almost a spreadsheet style .dat file that I can read the Row (or Line) numbers. But how do I read the line and column?
I am only familiar with using GetSetting & SaveSetting.
