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

Recommended Posts

390390390

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?

#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.
