_FTPEx _FTP_ListToArray problem (SOLVED)

[ozymandius257]

I have written a program to get files from a FTP site using _FTPEx.au3.

I'm using the _FTP_ListToArray function to get a list of the files, and everything seems OK on 64-bit OS, but it just hangs on a 32-bit OS.

Specifically, it is working on Windows 10 64-bit, and Windows 7 64-bit - but hanging on Windows 7 32-bit.

A snippet of the code I'm using is...

;read the list of files in the directory
    Write_To_Log("...getting the list of files on the FTP")
    Local $returnarray = _FTP_ListToArray($FTPConn, 2)
    If $returnarray[0] = 0 Then
        Write_To_Log("...error reading the list of files on the FTP - no files returned")
        Return False
    Else
        ;see if the file was found
        Local $filefound = False
        Local $i
        For $i = 1 To UBound($returnarray) - 1
            Write_To_Log("...found the file " & $returnarray[$i])
            If $returnarray[$i] = $FTPFileName Then
                $filefound = True
                Write_To_Log("...required file found")
            EndIf
        Next
    EndIf

Write_To_Log is a function that just writes out to a text file so I can see what's going on - it logs "...getting the list of files on the FTP" and then just hangs.

Anyone out there can help?

The functions are based on WinInet.dll, so you could try seeing what happens when you use this:

If DllOpen("wininet.dll") = -1 Then
    ConsoleWrite("! Error - Unable to open dll.")
Else
    ConsoleWrite("No issues finding Dll.")
EndIf

Thanks - tied up today, so I'll have a look tomorrow and get back to you.

@seadoggie01 - ran that - there were no issues finding the dll on win 7 32-bit.

Sorry, should've seen that. Sounds like you're getting stuck in the (internal) __FTP_ListToArray function... there's a do - while loop in there that is checking for another file. I read about the Dll calls it's making, but none seem to indicate anything different with 32/64 versions. You can try backing up FTPEx.au3 and editing it to try to find where it's erroring, but I don't see any issues 😐

@seadoggie01 - Durrr - of course - that should have occurred to me...

I'll get back to you....

It works fine on win7 32 bits for me.  Could you try another site ? I am using :

Local $sServer = 'speedtest.tele2.net'

@seadoggie01, @Nine - it's still not playing for me, so after lots of fiddling around with FTPEx, I found that it's hanging on the call to the function FtpFindFirstFileW - snippet from FTPEx.au3....

Local $aCallFindFirst = DllCall($__g_hWinInet_FTP, 'handle', 'FtpFindFirstFileW', 'handle', $hFTPSession, 'wstr', "", 'struct*', $tWIN32_FIND_DATA, 'dword', $iFlags, 'dword_ptr', $iContext)

It just hangs at that point.

@seadoggie01, @Nine - eventually I found out it's the windows firewall - on the 64 bit machines it was just allowing the connection through, but not on the 32-bit machine, even though port 21 was allowed - I had to turn on notifications on the 32-bit machine to get the program added to the firewall.
