Why am I getting this error? (Arrays)

[Aeterna]

==> Array variable has incorrect number of subscripts or subscript dimension range exceeded.:

CODE

Local $Follows[1000]

$FollowFile = "c:\follows.txt"

_FileReadToArray($FollowFile, $Follows)

$FollowNum = 0

$Follow = $Follows[$FollowNum]

func NextFollow()

$FollowNum = $FollowNum + 1

$PageNum = 1

$follow = $Follows[$FollowNum]

EndFunc

I'm getting this error when my program calls the NextFollow() function and it gets to the 3rd line of the function "$follow = $Follows[$FollowNum]"

Whats going on?

If $FollowNum > 999 ==> Array variable has incorrect number of subscripts or subscript dimension range exceeded.

If $FollowNum > 999 ==> Array variable has incorrect number of subscripts or subscript dimension range exceeded.

But this is happening when FollowNum is at like 2 or 3

You don't need to declare Follows as an array variable, it'll be an array when returning from _FileReadToArray function. The number of lines, which is also the upper bound of the array is stored into the first subscript. So if $Follows[0] = 50 then the highest valid subscript is $Follows[50].

Hmm, I'm not sure I understand.

Basically I have a list of names, 1 per line in a txt file which is being brought into an array

$FollowFile = "c:\follows.txt"

_FileReadToArray($FollowFile, $Follows)

$Follow = $Follows[$FollowNum]

$Follow is the name of the person I want to be using, called by the index $FollowNum which counts up so that after my code has ran, it switches to the next person.

func NextFollow()

$FollowNum = $FollowNum + 1

$follow = $Follows[$FollowNum]

EndFunc

Does that clarify what I'm doing? Or maybe you could rephrase your answer?

You need to check to make sure you don't go out of the array. Use UBound($Follows) to get the max that you can go to.

No idea what you are doing . . . .

Hope this helps

$FollowFile = "c:\follows.txt"
If Not _FileReadToArray($FollowFile, $Follows) Then
MsgBox(4096, "Error", " Error reading " & $FollowFile & " log to Array error:" & @error)
Exit
EndIf


For $i = 0 to UBound($Follows) -1
$Follow = $Follows[$i]
$PageNum = 1
Next

Actually $Follows[0] = the count not the first value, so the $i will need to start at 1 and go to the full without the -1 at the end.

If i remove:

Local $Follows[999]

Then I get the error:

==> Variable used without being declared.:

If Not _FileReadToArray($FollowFile, $Follows) Then

If Not _FileReadToArray($FollowFile, ^ ERROR

[Authenticity]

Dim $Follows

_FileReadToArray("C:\something.txt", $Follows)

Edit: Forgive me:

Local $Follows

_FileReadToArray("C:\something.txt", $Follows)

Always a good idea to declare all variables at the top

Dim . . .

Global . . .

Local . . .

Depending on your intended use.

keep the error code around the filereadtoarray . . . . it's good for letting you know what's going on. . . .

Thanks everybody, I got it working. There was some other ordering issues that was causing it to not function properly as well, but I couldn't have solved it without your advice! keep up the good work guys
