find last file in a handle

Recommended Posts


hey guys, its been awhile since i posted here but i have a simple problem that i need some help with, i searched around here and could not come across anything that was really helpful. Im just trying to find the last filename in a handle returned from FileFindFirstFile(). i have a directory full of images in the form of image-date-num, and i need my script to find the last file in the directory and return it as a $file variable. so if my last file in the directory is image-10-10-2010-15.jpg i need that to end up in my $file variable. any ideas of a clean way of doing this?

thanks in advance.

#include <array.au3>
$Directory = FileSelectFolder("Select Folder","")
$search = FileFindFirstFile($Directory & '\image-*.jpg')
$sOutput = ''
While 1
    $curfile = FileFindNextFile($search)
    If @error Then ExitLoop
    $sOutput &= $curfile & @LF
$aFiles = StringSplit($sOutput,@LF,3)

that's a starter, but as for sorting, since you are using the MM-DD-YYYY format, it will kinda be difficult to create a reasonable sorting without stripping apart each filename to get it in order of date then last image of the last date, I am guessing that is what you are aiming for?



$file = 'image-00-00-0000-0.jpg'
For $i in $aFiles
    $aCurrent = StringRegExp($i,'(?i)image-(\d\d)-(\d\d)-(\d{4})-(\d+?).jpg',1 )
    $aOld = StringRegExp($file,'(?i)image-(\d\d)-(\d\d)-(\d{4})-(\d+?).jpg',1 )
    if $aCurrent[2] >= $aOld[2] Then
        if $aCurrent[0] >= $aOld[0] Then
            if $aCurrent[1] >= $aOld[1] Then
                if $aCurrent[3] > $aOld[3] Then
                    $file = $i

not tested (I don't have a directory full of properly named files) but this may be right. worth a try

If you just want the last file found by FileFindNextFile() then keep track in a separate variable:

Global $sSearchDir = "C:\Temp"
Global $hSearch, $sLastFound = "", $sFound = ""

$hSearch = FileFindFirstFile($sSearchDir & "\*.jpg")
If $hSearch = -1 Then
    MsgBox(16, "Error", "No files found in " & $sSearchDir)

While 1
    $sFound = FileFindNextFile($hSearch)
    If @error Then ExitLoop
    $sLastFound = $sFound

MsgBox(64, "Results", "Last file found = " & $sLastFound)

But your definition of "last file" might not be the same as search algorithm used by the function. In that case you have to add your logic as in mekkutta's example.
