_FileListToArray problem

[fxdave]

Hi, I am David Biro, from Hungary.

I'm written a script:

#include <file.au3>
#include <array.au3>

Local $main_cats = _FileListToArray("system_cats/")
for $main_cat in $main_cats
   Local $cats = _FileListToArray("system_cats/" & $main_cat & "/")
   for $cat in $cats
     Local $programs = _FileListToArray("system_cats/" & $main_cat & "/" & $cat & "/")
     for $program in $programs
  
  
  
     Next
   Next
Next

And I got an error:

for $program in $programs

for $program in $programs^ ERROR

I think the code is correct.

It's bug?

fxdave,

Welcome to the AutoIt forum.

The is no bug.

You are asking _FileListToArray to return both files and folders - that is its default setting. So you might well then be asking the function to look for files and folders inside files - which means you do not get a array returned and so AutoIt announces an error. Try getting the function to return only folders - or check if the return is a folder - before getting it to look for files in the inner loop.

And in any case you need some errorchecking to cater for the event that the function does not return an array - and that the element is a valid path because the UDF returns a count in the [0] element.

Personally I would go for the other type of For and just loop through the arrays that way.

Typo

Do some error handling, to ensure the _FileListToArray returns an array (success)

If IsArray($programs) Then
...
EndIf
