Help with read/write arrays

[gazeranco 0]

Hey All,

I am still stuck with a problem here, the code I am using successfully writes a "3" to the last line in a file. The bit that is not working is the readto array and write from array. It doesn't give me an error when I run it but when I open the file. The contents of the text.txt file has not been written to the .spf file.

Can anyone see from the code why this isn't working??

Thanks,

#include <File.au3>
; Open the text file and read it ready for writing.

; Prompt the user to run the script - use a Yes/No prompt (4 - see help file)
Local $answer = MsgBox(4, "SPF-Editor", "Warning all SPF's in the .exe's directory will change, ok?")


; Check the user's answer to the prompt (see the help file for MsgBox return values)
; If "No" was clicked (7) then exit the script
If $answer = 7 Then
    Exit
    MsgBox(0, "SPF-Editor", "Buh Bye!")
EndIf

MsgBox(0, "Running", "The program will prompt you when it has finished!")

Local $filer = FileOpen("text.txt", 0)

; Check if file opened for reading OK
If $filer = -1 Then
    MsgBox(0, "Error", "Unable to open file!!")
    Exit
EndIf

; Start finding files for writing.
; Shows the filenames of all files in the current directory
Local $search = FileFindFirstFile("*.spf*")

; Check if the search was successful
If $search = -1 Then
    MsgBox(0, "Error", "Eeeeeroar!!")
    Exit
EndIf
Global $Text = "", $Array
$line = FileRead($filer) ; reads the entire file at one time

_FileReadToArray($filer, $Array)

While 1
    Local $file = FileFindNextFile($search)
    If @error Then ExitLoop

    Local $CountLines = _FileCountLines($file)
    _FileWriteToLine($file, ($CountLines), "3", 1)

    _FileWriteFromArray($file, $Array) ; writes $$Array to $File

WEnd
MsgBox(0, "Done", "The script has stopped and your files are edited!")

; Close the search handle mofo
FileClose($filer)

FileClose($search)

Specifically, this is the area where I think I am missing something...

Global $Text = "", $Array
$line = FileRead($filer) ; reads the entire file at one time

_FileReadToArray($filer, $Array)

While 1
    Local $file = FileFindNextFile($search)
    If @error Then ExitLoop

    Local $CountLines = _FileCountLines($file)
    _FileWriteToLine($file, ($CountLines), "3", 1)

    _FileWriteFromArray($file, $Array) ; writes $$Array to $File

WEnd

gazeranco,

Your problem is here:

$line = FileRead($filer) ; reads the entire file at one time

_FileReadToArray($filer, $Array)

Go and look at the parameters you nee to use for _FileReadToArray - you need the filename, not the file content.

And here:

_FileWriteToLine($file, ($CountLines), "3", 1)

_FileWriteFromArray($file, $Array) ; writes $$Array to $File

You are correctly changing the last tine with _FileWriteToLine, but then immediately overwriting it with the non-existent array.

And you are yet another one who uses the cumbersome FileFindFirst/NextFile pair when it is so much easier to use _FileListToArray to do all the work for you.

Try this script which works for me to convert all of the final lines of the *.spf* files to "3":

expandcollapse popup

#include <File.au3>

; Prompt the user to run the script - use a Yes/No prompt (4 - see help file)
Local $answer = MsgBox(4, "SPF-Editor", "Warning all SPF's in the .exe's directory will change, ok?")


; Check the user's answer to the prompt (see the help file for MsgBox return values)
; If "No" was clicked (7) then exit the script
If MsgBox(4, "SPF-Editor", "Warning all SPF's in the .exe's directory will change, ok?") = 7 Then
    MsgBox(0, "SPF-Editor", "Buh Bye!")
        Exit
EndIf

MsgBox(0, "Running", "The program will prompt you when it has finished!")

Local $filer = FileOpen("text.txt")

; Check if file opened for reading OK
If $filer = -1 Then
    MsgBox(0, "Error", "Unable to open file!!")
    Exit
EndIf

; Start finding files for writing.
; Shows the filenames of all files in the current directory
Local $aList = _FileListToArray(@ScriptDir, "*.spf*", 1)

; Check if the search was successful
If Not IsArray($aList) Then
    MsgBox(0, "Error", "Eeeeeroar!!")
    Exit
EndIf

; Now loop through the files
For $i = 1 To $aList[0]
    ; Get line count
    $iCount = _FileCountLines(@ScriptDir & "" & $aList[$i])
    ; And change the final line
    _FileWriteToLine(@ScriptDir & "" & $aList[$i], $iCount, "3", 1)
Next

; No idea why you opened it - but you need to close it sometime
FileClose($filer)

Please ask if you have any questions.

Hey,

That's a bit complex for me, I will try and understand it!!

It does what I want, it replaces the last line with "3" now I just need it to read from text.txt and write from text.txt to the current file. I don't understand the _writefromarray command though, it's a little confusing for me at least... text.txt currently just contains...

LINE1
LINE2
LINE3
LINE4
LINE5
-1

I will try and let you know how I get on. Thanks for the help!!

gazeranco,

I just need it to read from text.txt and write from text.txt to the current file

It is always better to explain exactly what you want in the beginning - saves a lot of time and wasted effort from those who try to help.

Are you saying that you want to add the contents of the .txt file to the end of each *.spf* file? If so then you can use FileWrite directly.

expandcollapse popup

#include <File.au3>

If MsgBox(4, "SPF-Editor", "Warning all SPF's in the .exe's directory will change, ok?") = 7 Then
    MsgBox(0, "SPF-Editor", "Buh Bye!")
        Exit
EndIf

MsgBox(0, "Running", "The program will prompt you when it has finished!")

; Read the text you want to add
Local $sText = FileRead("text.txt")

; Check if file opened for reading OK
If $sText = "" Then
    MsgBox(0, "Error", "Unable to open file!!")
    Exit
EndIf

; Start finding files for writing.
; List the filenames of all *.spf* files in the current directory
Local $aList = _FileListToArray(@ScriptDir, "*.spf*", 1)

; Check if the search was successful
If Not IsArray($aList) Then
    MsgBox(0, "Error", "Eeeeeroar!!")
    Exit
EndIf

; Now loop through the files
For $i = 1 To $aList[0]
    ; Open the .spf file for appending data - parameter = 1
    $hFile = FileOpen(@ScriptDir & "" & $aList[$i], 1)
    ; Add the data
    FileWrite($hFile, $sText)
    ; And close it
    FileClose($hFile)
Next

Again ask if you have any questions.

How is this thread any different from your You will need to include a copy of the .spf file so we can figure out EXACTLY what's in that file to replace.

Brewman,

different in that last time the loop confused me, then we digressed and you solved most of my problems.

But this time specifically, I didn't understand what I was doing with the readarray/writearray and couldn't get it working, as the last title was loop in a loop i decided a new post was appropriate.

Melba,

Thats excellent, seems to work perfectly for my files. I will try and understand it all and possibly fire a few questions at you if I don't understand anything!

Cheers,
