Reading a file to an array and outputting it in a text file...

[BlueScreen]

Hi All,

I am trying to read a simple text file (small.txt) (attached) to an array and put all it's content in another text file (output.txt). File are not identical (I have compared them). Looks like that in the output.txt file, there is always an extra line?

Why?

Can it be do without this extra line???

Thanks,

#include <file.au3>

Dim $aRecords

If Not _FileReadToArray("c:\small.txt",$aRecords) Then

MsgBox(4096,"Error", " Error reading log to Array! error:" & @error)

Exit

EndIf

$x=Fileopen ("c:\output.txt",2)

For $i=1 to 3

If $i<>3 Then

Filewriteline ($x,$arecords[$i] & @LF)

Else

Filewriteline ($x,$arecords[$i] & @CR)

EndIf

Next

small.txt

follow the process that help gives you

#include <file.au3>
Dim $aRecords
If Not _FileReadToArray("error.log",$aRecords) Then
   MsgBox(4096,"Error", " Error reading log to Array     error:" & @error)
   Exit
EndIf
For $x = 1 to $aRecords[0]
    Msgbox(0,'Record:' & $x, $aRecords[$x])
Next

thus

#include <file.au3>
Dim $aRecords
If Not _FileReadToArray("error.log",$aRecords) Then
   MsgBox(4096,"Error", " Error reading log to Array     error:" & @error)
   Exit
EndIf

$i=Fileopen ("c:\output.txt",2)

For $x = 1 to $aRecords[0] -1
    Msgbox(0,'Record:' & $x, $aRecords[$x])
    Filewriteline ($i,$arecords[$x] & @CR) 
Next

Filewriteline ($i,$arecords[$x] )

oh yea and file close

Thanks, Valuater...

I have run your posted script, files small.txt and output.txt are not identical.

Try it...

[Valuater]

#include <file.au3>
Dim $aRecords
If Not _FileReadToArray("error.log",$aRecords) Then
   MsgBox(4096,"Error", " Error reading log to Array     error:" & @error)
   Exit
EndIf

$i=Fileopen ("c:\output.txt",2)

For $x = 1 to $aRecords[0] -1
    Msgbox(0,'Record:' & $x, $aRecords[$x])
    Filewriteline ($i,$arecords[$x] & @CRLF)
Next

Filewriteline ($i,$arecords[$x] )

this does it

Sorry, Valuater...

I have compared the files using Total commander. Files are NOT identical...

[Valuater]

ok...

this does the trick

$File_1 = "c:\small.txt"
$File_2 = "c:\output.txt"

$file_info = FileRead($File_1, FileGetSize($File_1))
FileWrite($File_2, $file_info)

The file "small.txt" is in c:\

This is (your) script I'm running( changed the line you mentioned)

#include <file.au3>

Dim $aRecords

If Not _FileReadToArray("c:\small.txt",$aRecords) Then

MsgBox(4096,"Error", " Error reading log to Array error:" & @error)

Exit

EndIf

$i=Fileopen ("c:\output.txt",2)

For $x = 1 to $aRecords[0] -1

Msgbox(0,'Record:' & $x, $aRecords[$x])

Filewriteline ($i,$arecords[$x] & @CRLF)

Next

Filewriteline ($i,$arecords[$x] )

Attached is a screenshot confirming that they are not identical and that there is an extra empty line at the end of output.txt. Looks like it was created when file was opened?

[Valuater]

re-posted script... try again

Thanks, man. It does the trick...

The issue is that I have a BIG text file to read and must use FileWriteLine to write in the output file, since I will not want to write the entire file (only sections of it depending of a condition) I will like to use the FileReadToArray... Possible?

[Valuater]

yes... lete me take another look at what i can do

Thanks!!!!! I will also post my entire script soon...

[Valuater]

this will do it..

$File_1 = "c:\small.txt"
$File_2 = "c:\output.txt"

#include <file.au3>
Dim $aRecords
If Not _FileReadToArray($File_1,$aRecords) Then
   MsgBox(4096,"Error", " Error reading log to Array     error:" & @error)
   Exit
EndIf

$i=Fileopen ($File_2,2)

For $x = 1 to $aRecords[0] -1
    Filewriteline ($i,$arecords[$x] & @CRLF)
Next

Filewrite ($i, ($arecords[$x]))

Thanks Valuater... This is close enough

On the posted script, if you open Notepad, files seems indentical, however, if you compare them using total commander, you will observe that there is an empty line (god knows from where it came) between each written line... I have overcome it by changing from Filewriteline ($i,$arecords[$x] & @CRLF) to Filewriteline ($i,$arecords[$x] & @LF)

Thanks, dude

Although it works, it strange since in the HELP file it is written: "If the line does NOT end in @CR or @LF then a DOS linefeed (@CRLF) will be automatically added.", so why in the last line of code posted there is no empty line as it should be (since there is no @CR ot @LF in the code line)

Hmmmm....
