If you used it, you would of atleast found out how to open & write to a file...

do 4 backspaces?

means "delete 4 characters"?

So your script would consist of

fileread (reads file into a single variable)

delete characters

filewrite (writes file from a single variable)

[idenniske]

$file = FileOpen("C:\xampp\htdocs\test\kennislong.txt", 0)

If $file = -1 Then

MsgBox(0, "Error", "Unable to open file.")

Exit

EndIf

FileClose($file)

It won't open my file

[FinalVersion]

$file = FileOpen("C:\xampp\htdocs\test\kennislong.txt", 0)

If $file = -1 Then

MsgBox(0, "Error", "Unable to open file.")

Exit

EndIf

FileClose($file)

It won't open my file

• Can you open it with notepad?

Your code can't work. FileOpen opens the file to use with FileRead and FileWrite. You can't switch to Notepad because Notepad hasn't been started yet.

You're mixing to Autoit "concepts".

Concept 1: Read a file, change and write it with pure autoit

Concept 2: Open the file with another program (notepad) and do all the work using the GUI of the program.

So first you should decide how to do the job.

To get you started:

• How large is your file?
• Where are the characters you want to delete (the first 4 characters, the last, somewhere in the middle)?

oops my bad sorry

[idenniske]

oops my bad sorry

Don't you guys have a example that works so i can test it?

[picaxe]

$trimchar = 4
$eol = @CRLF

$file1 = "$$$test.txt"
$file2 = "$$$test trimmed " & $trimchar & " chars.txt"

If FileExists($file1) Then FileDelete($file1)
If FileExists($file2) Then FileDelete($file2)

$j = ""
For $i = 1 To 10000
    $j &= "This is line " & $i & " This is line " & $i & " This is line " & $i & " This is line " & $i & $eol
Next
FileWrite($file1, StringTrimRight($j, 2))
$start1 = TimerInit()
$text = FileRead($file1)
$readtime = Round(TimerDiff($start1)/1000, 3)
ConsoleWrite("file read time: " & $readtime & "sec" & @LF)

$start2 = TimerInit()
FileWrite($file2, StringTrimRight($text, $trimchar))
ConsoleWrite("create file " & $file2 & " with " & $trimchar & " chars removed from end, time: " & Round(TimerDiff($start2)/1000, 3) & @LF)

is it posible to open the notepad so i can see what happens.

right now i have this:

$fileVariableName = FileOpen("input.txt", 0)

If $fileVariableName = -1 Then

MsgBox(0,Failure,Failed to open file)

Exit

EndIf

While 1

With a error called : parse error.

I'm hopeless

Usually it is more error prone to do something using the GUI. Couldn't you use picaxe's code and test if it does what you need? The stripped down code would look like:

$trimchar = 4

$inFile  = "C:\xampp\htdocs\test\kennislong.txt"
$outFile = "C:\xampp\htdocs\test\kennislong_trimmed.txt"

If FileExists($outFile) Then FileDelete($outFile)
$text = FileRead($inFile)
If $text = -1 Then
    MsgBox(0, "Error", "Unable to open file.")
    Exit
EndIf
FileWrite($outFile, StringTrimRight($text, $trimchar))

Thanks guys this works.

i do have one more question.

It seems that i have a lot of white spaces, so the trimmed chars are spaces. Is it posible to pick out the last four chars ),(, ?
