How to find and replace a string in a doc file?

[atari]

Hi all!

I'd like to ask for help, my problem is the following:
I have a doc or rtf file and I have to find a string in the file and replace it for another stirng automaticly without any editor.
For example by pressing a key....
How should I do this?
Any good idea I would appreciate!


Regards,
Atari

Attached is a raw sample written on the fly.
Textbox1.Text replaces the "RecordToBeDeleted" in the txt.txt file.
It's up to you to customize the sample....at least it works.

No doubt some grands here can suggest a better solution

If the file is not too large you can read it to a string with FileReadToEnd, replace the string with StrReplace and save it by overwriting the file.

For large files it is better to read the file one row at a time, update it if necessary and write it to a new file.

But then you need to know if the string to be replaced could span more than one line...

In that case you should try to read the whole string, update it and save it to a file.
