FileReadLine weirdness

3 posts in this topic

So this little piece of code opens a file and then reads it in line by line.

#include <File.au3>

$message = "Please select a file to convert"
$initialDir = "W:\Testing\Tools\Diehard"
$InputFile = FileOpenDialog($message, $initialDir & "\", "All (*.*)", 1 )

If @error Then
    MsgBox(4096,"","No File(s) chosen")
    exit
Else
    $InputFile = StringReplace($InputFile, "|", @CRLF)
EndIf

While 1
    $line = FileReadLine($InputFile)
    if @error = -1 then ExitLoop
    msgbox(0, "Line read: ",$line)
WEnd

Fileclose($InputFile)
FileClose($OutputFile)

Problem is, it just keeps displaying the first line of the file over and over again.

I've attached the file that it is reading in, in case it helps diagnose the issue.

TIA

FileOpen is missing.

I guess FileReadLine opens the file, reads a line and closes the file. And does this over and over again. You need something like:

$hFile = FileOpen($InputFile)
While 1
    $line = FileReadLine($hFile)
    if @error = -1 then ExitLoop
    msgbox(0, "Line read: ",$line) 
WEnd
FileClose($hFile)
