Writing to a txt file

[mavrick]

Hi

I need to write to a txt file, but I don’t want to replace the whole file, only certain text in the file.
Can this be done?
Using ASP.

Thanks

This is a bit crude, but it should do the job...

* Read File in to a string (Using the FileSystemObject)

* Do a Replace() or a RegEx Replace on the string

* Save String to File (Using the FileSystemObject)

Shout if you need anything explaining.

Hopefully someone else will come along with something more elegant!

HI

Got the first part done...

Not sure about
"Do a Replace() or a RegEx Replace on the string"

thanks

Am I missing something?

Wordpad will call up .txt files of most any size.
Just suck the file in and edit your changes at will.
Be sure to rename and save both old and new files in case of errors.
Done. -Larry

do you know the text that you want to replace?

if you know the text you want to replace it is simple...

newversion=replace(oldversion,'old text string','replacement text string')

[topr8]

you can also use regex to do the replace, to replace against a list of words or everything between a predefined start and stop word or any other normal regex match.

you need to set a regex object to do this.

>>Am I missing something?

you are right larry but i think this needs to be done server side not locally.

Once you understand the basis, you can visit [regexlib.com...] for usage.

regex (short for regular expressions) is straightforward - it is basically a way of matching strings.

the way you can implement regex in asp is not great, there is a built in object RegExp that you can use, a search for that should give you some tutorials.
