Although an ini file is just a plain text file ini files have a structure

[SectionName1]
Keyname1=abc
Keyname2=123

If your ini file is like this all you need to know is the section-name(s)
and key-name(s) you are concerned with (and of course the file-name & path).
APIs GetPrivateProfileString and WritePrivateProfileString to read/write the
values will do all the work for you. I'm sure if you search these terms
together with something like "modify ini file" you will find hundreds of
examples.

Hello,

When writing multiple values to a .ini file I'm familiar with the
following basic code:

Open "c:\my.ini" For Output As #1
Print #1, "1"
Print #1, "2"
Print #1, "3"
Close #1

Is there a way to modify/write values to specific lines only, for
example modifying the "2" value on line 2 to "5", without overwriting
the other lines with their unchanged values?

Thanks for any feedback!

Jim
