String problem How to delete and replace line

[Tom]

Could someone please point me to an example of how to delete
and replace a specific line in a text file? I use several colums that store
settings
and everything works fine except I can't figure out how to delete a specific
line
and replace it. I can keep adding settings but can't delete and replace.
Everything I try results in either adding a new line or just deleting a line
or a currupted file.

Thanks
Tom

Try this:

Find and Replace Multiple Values from a Text File

Use the Configuration File VIs to read/write settings to file; much easier.
