How do I sustain a variable outside of a "While"?

[390390390 0]

I have a folder that will contain one unique filename, always ending in the extension .4@Y. I'm using the following code to give my script the file name:

;Get the filename
$search = FileFindFirstFile("C:\*.4@Y)

While 1
    $filename = FileFindNextFile($search)
    If @error Then ExitLoop
Wend

FileClose($search)

Now if I insert my message box-- MsgBox(0,"File Name", "This is your file: " & $filename) before the "Wend" it works like a charm. If I put it at the end the variable is lost.

Is there a way to keep the $filename variable outside of the While statement? I suspect I should use a Dim, but I really don't know. Can anyone help?

GIVE ME THE "d"

GIVE ME THE "I"

GIVE ME THE "m" ...

WHAT DOES IT SAY ?????? ....

DIM .. DIM ... DIM .... DONG !!! ... yes you are right I think there´s a DIM missing at the top of the program !!!

#include <Array.au3>
Local $FoundFiles

;Get the filename
$search = FileFindFirstFile("C:\*.4@Y")

While 1
    $filename = FileFindNextFile($search)
    If @error Then ExitLoop
    $FoundFiles &= $filename & '|'
Wend
FileClose($search)
$FoundFiles = StringTrimRight($FoundFiles, 1)
$FoundFiles = StringSplit($FoundFiles, '|')
_ArrayDisplay($FoundFiles)

If you are attempting to run the code you gave inside a function and read the value outside of that function then it would account for this problem. That can be solved like this.

;
Global $FileName
Func _FindMyFile()
;Get the filename
Local $search = FileFindFirstFile("C:\*.4@Y)
While 1
    Local $filename = FileFindNextFile($search)
    If @error Then ExitLoop
Wend
FileClose($search)
EndFunc
MsgBox(0,"File Name", "This is your file: " & $filename)
;

OR

;
$Filename = _FindMyFile()
MsgBox(0,"File Name", "This is your file: " & $Filename)
Func _FindMyFile()
;Get the filename
Local $search = FileFindFirstFile("C:\*.4@Y)
While 1
    Local $filename = FileFindNextFile($search)
    If @error Then ExitLoop
Wend
FileClose($search)
Return $Filename
EndFunc
;

Just remember that, if there is more than 1 matching file, only the last match will be returned.

Global is preferable to DIM but it makes for a bad cheer.
