_FileListToArray @error always "0"

[moorsey]

I have copied and changed slightly the _FileListToArray example from the AutoIt help file. The example has 2 error popups, if the folder path is wrong and if there are no files found at the target directory.

I also added some log writing to these.

But, instead of any of this happening when I simulated these errors, the script continues and errors out when the array is referenced and found to be empty

Here is my code

Local $FileList = _FileListToArray($spath,$sfilter)
_FileWriteLog($LogFile, "File list read into array") ; Write to the logfile passing the filehandle returned by FileOpen.
FileClose($LogFile) ; Close the filehandle to release the file.
MsgBox(0,"",@error)

If @error = 1 Then
    MsgBox(0, "", "No Folders Found.")
_FileWriteLog($LogFile, "Specified folder & $sPath & not found") ; Write to the logfile passing the filehandle returned by FileOpen.
FileClose($LogFile) ; Close the filehandle to release the file.
    Exit
EndIf

If @error = 4 Then
    MsgBox(0, "", "No Files Found.")
_FileWriteLog($LogFile, "No & $sFilter & files found in & $sPath") ; Write to the logfile passing the filehandle returned by FileOpen.
FileClose($LogFile) ; Close the filehandle to release the file.
    Exit
EndIf

I checked the error code by just putting a message box in to display the @error after the files had been read in.

Any ideas on this?

Many thanks

Did you check to make sure that you weren't getting errors 2 or 3?

moorsey,

Your error checking is a little off because your checking @error after FileClose which doesn't set @error. You need to check @error after _FileListToArray e.g.

#include <Array.au3>
#include <File.au3>

Local $aArray = _FileListToArray(@ScriptDir)
_ArrayDisplay($aArray, "_ArrayDisplay: " & @error)

ahh, of course, that solves the issue

very much appreciated for pointing out my error!
