Delete text from TXT file

[DaLiMan]

I have a textfile wich I read with a GUI script.

Now I like to have the ability to select and delete the item from the file.

File is like:

line1

line2

line3

Now I know how to select an item, but I can't figure out how to remove it from my textfile.

Please help me for I'm very very stuck on this one.....

Do you wanna delete the whole content of the file, a line or just a specific word?

[themax90]

A combination of _FileCountLines and deleting the file? Or opening the file in a write(overwrite existing contents) flag? Some kinda form of it?

@ Doxie

I only want to delete the line I have selected.

The rest must remain intact.

@ Agent Smith

I was also thinking about reading the whole file into the array, delete the line from the array and then paste it back.

But I how can I make the file empty?

I will make an example script for you that does that.

You should simply just read the file into an array, delete the value that you do not want, and then write over the entire file.

[Coffee]

FileOpen ( "filename", mode )

Parameters

filename Filename of the text file to open.

mode Mode (read or write) to open the file in.

0 = Read mode

1 = Write mode (append to end of file)

2 = Write mode (erase previous contents)

Both write modes will create the file if it does not already exist.

use sparringly though erases all content of .txt file

K FIRST you read it into an array, there's a UDF for that I think.

THEN you close that connection, open it again in the 2nd mode, write to it with the new values. Very simple I think.

Sorry, I've been busy. I thought I could make it in 5 minutes but something came up.

That's OK, thanks anyway.

I'm working on it right now and I think it will work with:

FileRead, StringReplace and _FileCreate.

P.S.: If someone is interested let me know, then I will C&P the code when it works.

P.S.(2):Thanx everybody for all the reply's.

They put me back on the right track.

I regularly add junk senders to my junk senders list in Outlook - a txt file and I used to go in each time to delete everything to the left of and including the '@' sign. I recently wrote this script to do it for me. It may be a useful start for you.

$file=FileOpen(@AppDatadir & "\Microsoft\Outlook\Junk Senders.txt",0)
$file2="C:\My Documents\Backup\Restore\Junk.txt"
While 1
$line=FileReadLine($file)
if @error = -1 then exitloop
$len = StringLen($line)
$pos = StringinStr($line,"@")
$line2 = StringRight($line,$len-$pos)
FileWriteLine($file2,$line2)
wend
FileClose($file)
FileMove(@AppDatadir & "\Microsoft\Outlook\Junk Senders.txt",@AppDatadir & "\Microsoft\Outlook\JunkOld.txt",1)
FileMove("C:\My Documents\Backup\Restore\Junk.txt",@AppDatadir & "\Microsoft\Outlook\Junk Senders.txt")

exit

All the best.
