[SOLVED] _FTP_FilePut error / strange behaviour

Recommended Posts

Posted (edited)

The following function successfully connects to and uploads a local text file named user.dat

I have checked the data being written to the text file when it is created locally using a MsgBox and it appears exactly how it should be written to the file. If I comment out the FileDelete and go and open the file locally it is as expected.

However when I download the file from the FTP server and open it up the text that should be at the end of the file is missing. With each subsequent run more characters are missing.

I added the Sleep(5000) in case the function was closing the FTP connection too quickly before the file could be fully written but it makes no difference. The user.dat file is (should be) approximately 100 bytes so it is tiny.

Any idea why this is happening?

Func UpdateUserData() ; Upload the modified user.dat file
    Local $hOpen = _FTP_Open("myftp")
    Local $hConn = _FTP_Connect($hOpen, "my.ftp.server", "user", "pass", 1, 0, 1, 2)
    If @error Then
        MsgBox(16, "Error", "Connection failed" & @CRLF & @CRLF & "Please contact support")
        _FTP_Close($hConn)
        _FTP_Close($hOpen)
        Exit
    EndIf
    _FTP_FilePut($hConn, @TempDir & "\user.dat", "user.dat") ; Upload the new user.dat file
    Sleep(5000)
    If @error <> 0 Then
        MsgBox(16, "Error", "Couldn't transmit data" & @CRLF & @CRLF & "Please contact support")
        _FTP_Close($hConn)
        _FTP_Close($hOpen)
        Exit
    EndIf
    _FTP_Close($hConn)
    _FTP_Close($hOpen)
    FileDelete(@TempDir & "\user.dat")
EndFunc

Solved. Thanks to Dent for working on this so diligently. Turns out if I _FTP_FileDelete the file first then the newly uploaded one is fine. I may well have discovered an FTPEx.au3

      Hello,
      This is my first post. So I’ve worked on a script for a while and I’m planning to publish it but the problem is that it connects to an FTP server at some point, and as you probably know FTP credentials are easily captured by a MITM attack or Wireshark (not sure if Wireshark does). So I thought if i can detect data capturing in the user’s network the script would stop. Any idea?.
      If there’s another workaround I’m happy to hear it.

      Hello,
      I am attempting to pull a list of the directory structure from a public FTP where no username or password is required i.e:
      ftp://ftp.adobe.com/pub/adobe/
      Now I have looked all over the place and have failed find anything to accomplish, and if I found some, and the documentation is rather bleak for example;
      it does show something I am looking for, but there is no ftp.au3, and the usage and examples of what i want to do seems to elude me on this and it may not even apply to what I am trying to accomplish?
      I want to avoid using things with Internet explorer , and I have done some google searches. However nothing seems to help
      the documentation surrounding : _FTP_DirGetCurrent  references _FTP_Connect , and then references _FTP_Open , and regardless what I try I cannot get it to pull a list of directorys of files as a list.
       
      Any help is appreciated

      Hi,
      Ones(some times twice) a month I get an e-mail with zip file, which has price updates from a supplier.
      I have to upload the file to an FTP to get it processed.
      When uploading the file, it will get "timestamped" with the time and date at which time the file was uploaded.
      Normally this is fine, because I mostly upload the file the same day.
      Sometimes it may take 1 or 2 days before I can upload the file.
      For historical purpose, I would like to have the file timestamped with the original date.
      I have tried using:  _FTP_Command ( $hFTPSession, "MFCT YYYYMMDDHHMMSS path") 
      however this command does not work or change the timestamp as I expected.
      Does anyone now a way how I can change the timestamp of a FTP-file?

      Hello,
      i need help in deleting files from a server. The function "_FTP_DirDelete" only deletes a directory when its empty. I need to delete a non empty directory. I also can not delete the files in this directory first, because the files are PAG and DIR files in a .DAV directory and FTPEx.au3 doesnt like a directory starting with a ".".
      Any ideas?
      Thx, Sally

      Hi,
       
      I have written a small script to read a file from an FTP server and check its contents. This can be re-run by the press of a button, however, if the file is deleted from the ftp server between runs (with the .exe still live), the file is still "read" and written locally, which then passes the check.
       
      If I run it initially without the file, it correctly fails and pops up my error message, but if the file is then added, it then seemingly gets cached (or similar) so that the app then always reports a success.
       
      The below code snippet is just the function run when the "test" button is pressed. It includes a load of debug message boxes, and from that I think I've gathered a few (possibly) interesting/relevant things:
      $Open and $Conn are 8 byte values, which increments (not by 1) when the FTP connection is not closed, but if the connection is closed, they stick at the value (presumably windows can re-use that session id if it's been closed e.g:
      1st run (file not present) $Open -> 0x00CC0004 $Conn -> 0x00CC0008
      2nd run (file not present) $Open -> 0x00CC0010 $Conn -> 0x00CC0014
      3rd run (file now present) $Open -> 0x00CC001C $Conn -> 0x00CC0020
      4th run (file still present) $Open -> 0x00CC001C $Conn -> 0x00CC0020
      $Ftp = _FTP_FileGet.... returns a 1 when file not present (in a run after it was present) and "test_transfer.txt" does get created and does contain the correct string This is the key bit I dont understand, I dont know how/where it is getting the data to write this file when it literally no longer exists on the target FTP server...
      resetting every variable used in the function each time it's run does work (in that they become 0), but it doesn't affect the putcome I had thought perhaps some key values were being stored in the variables, but this doesn't seem to be the case
       
       
      Is there any concept of clearing a cache when closing an ftp session? Or deleting any unknown temporary files windows might make?
       
      Thanks all
