_FTP_FileRead problem

17 posts in this topic

Hy all! Sorry of my bad english, but I have a problem.

This part of code must read the file on FTP (that was previous connected) and return what chars are in the file

$CHR = '/,^'

all is going good but when I press sumbit button ($SUMBIT) again, it return the same that the first time (even if needed file was changed)

please help me with this=)))

Case $SUMBIT
        GUICtrlSetData($STATUS, 'Stand by...')
        GUICtrlSetColor($STATUS, 0x0000FF)
        $CHR = GUICtrlRead($CHR)
        $FILE = GUICtrlRead($FILE)
        $FILEOPEN = _FTP_FileOpen($hConnect, $FILE)
        $FILEREAD = _FTP_FileRead($FILEOPEN, 100000)
        $STR = BinaryToString($FILEREAD)
        $a = StringSplit($CHR, ',')
        For $i = 1 To $a[0]
            If StringInStr($STR, $a[$i]) Then $LOG &= $a[$i] & ' found!' & @CRLF
        Next    
        GUICtrlSetData($STATUS, 'Connected')
        GUICtrlSetColor($STATUS, 0x00FF00)
        TrayTip('', $LOG, 30)
        _FTP_FileClose($FILEOPEN)

Not seeing much, but I observe you don't check error condition anywhere. Could be simply that the second open doesn't work for some reason and $str gets self-identical.

You were right! when I set error after reading file error has been occured...

but I dont understand why... :(

$FILEOPEN = _FTP_FileOpen($hConnect, $FILE)
        $FILEREAD = _FTP_FileRead($FILEOPEN, 100000)
        If @error Then MsgBox(16, 'error', 'error reading file')

Perhaps because the _FTP_FileOpen fails? Error checking really should be done after every call where an error can possibly occur. FTP is blatantly error-prone, much more than GUI_CreateLabel. So while error-checking the latter is reasonably optional, doing sameafter the former is essentially obligatory.

Thanks for pointing out this truth with your example :(

I just want to remind you to be careful with that. Our rule on bumping is to wait 24 hours, ignore it too often and you will find yourself very unpopular. :)

That can't hurt and possibly catch error(s) occuring there.

$FILE = GUICtrlRead($FILE)

$FILEOPEN = _FTP_FileOpen($hConnect, $FILE)

If @error Then

MsgBox(16, 'Error', 'Error opening file!')

Exit

EndIf

$FILEREAD = _FTP_FileRead($FILEOPEN, 100000)

If @error Then

MsgBox(16, 'Error', 'Error reading file!')

Exit

EndIf

Posting will destroy formatting but you get the idea.

Sorry for hyper-elliptic english, I'm not native.

Can you FTP-read the file giving error with a known-working product (browser, Filezilla, ...)?

What is the @error returned by _FTP_FileRead and the returned size? What is the actual file size?

1) I just mean: can you check that it's possible to ftp-read the file using temporarily another product known to work. Then you'll see if there is some extra problem (access right or something).

2) ConsoleWrite("@error = " & @error & @LF) <-- insert right after _FTP_FileRead(...) or else @error will get overwritten by another function.

3) the return value of _FTP_FileRead(...) is the number of byte successfully downloaded.

4) check that something else (like anti-virus program) isn't blocking the download by detecting false or true positive on this particular file.

1.access rights is allright because I did that ok

2.@error = 0 ;first read

@error = 2 ;second read

3. I insert this 'MsgBox(0, '', $FILEREAD)' and $FILEREAD = 0

4.anti-virus is allright too

An error value of 2 doesn't seem to mean anything. I spent much time on MSDN o no avail.

Honest, I've no idea what happens. Normally, all FTP download forces reload even if the file is on cache (that's because the file could have changed in the meantime on the server). So it should work, but...

Is that a FTP server or HTTP or something else? If FTP, you could try _FTP_FileGet. Maybe that would work better
