ReadDirectory function crashes

Hi, i am trying to download the contents of n FTP folder using your library components. Everything works fine until the folder reaches a particular size, then it crashes on the ReadDirectory call.

My folder size is 1.25GB, one of the files is 658MB and then the largest file is 121MB. From here all other files are between 2MB and 25MB.

Can you please inform me when s fix will be out?

Cheers

Hello ..

Can you reproduce the problem with the SmartFTP FTP client? If yes, can you post or email the raw directory listing of the directory where it crashes?

Thanks
-Mat

Yes the problem does occur with the client as well as the library, how do i send you a raw listing?? I am not sure how to do this or what it is.

Is it the listing of all the files and the size of each one??

Cheers

The directory is actually a virtual directory and cannot be seen unless you type a command into your FTP client, so i had to do the DIR command from the command prompt.

Volume in drive D is Data
Volume Serial Number is 922C-7B84

If you cannot see the directory within SmartFTP, but still access it, you can toggle the command line pane (Shift-F5) and enter CWD <dir_name> there. Then SmartFTP will change into the directory and will display it in the tree view. Then you can select to show the Raw Listing from the directory context menu.

My main concern is your library modules as i have wrote a simple program using your library that downloads all these files to our office. Once the readDirectory command has been done, it takes a very long time to read, then as soon as it starts to download the first file, it seems to lose the connection and attempts to reconnect.

If you would like the code that i have wrote please ask.

Hello ..

The raw listing you sent doesn't look complete because your data tranfser got aborted. Please send the complete listing. Please provide all information we requested. And this listing should crash the SmartFTP client?

Thanks
-Mat

Here is the listing again. It will read ok in the client, but not in the library version. But if you try to download all the files then it will crash both.

Thanks.

The FTP client uses the FTP Library. Thus my guess is that the data transfer of the directory listing is unsuccessful and therefore the actual data (listing) never gets parsed. Try to set the correct data connection settings (Passive, DataConnectionType, DataConnectionMode, DataProtection, etc). You can also get a logfile from the FTP Library and you will see what doesn't work.

Regarding the crash. Your statement that SmartFTP is crashing when downloading the files is not very helpful. And secondly, you say the FTP Library cannot parse the directory listing but it's crashing when downloading the files inside this directory. Hmm
If you can provide crash dumps which are automatically created we can try to look at it. Use the latest SmartFTP version before you produce the crash:

Mat,

Basically when i run the custom code i have to download all the files in that directory, the code seems to read the directory, which it takes a while doing, and then as soon as it starts to try to download the first file, it says the connection has been lost and attempts to reconnect again.

Would you like the code??

Will this exe file, that you have sent me a link to, include a newer version of the library??

I am not really using the client, as i have wrote the code so it downloads automatically, but i will try it if you want??

Mat,

I have added the following and it appears to work.

FTP.DataProtection = sfFTPLib.enumDataProtection.ftpDataProtectionPrivate
FTP.DataTransferMode = sfFTPLib.enumDataTransferMode.ftpDataTransferModeStream
FTP.DataTransferType = sfFTPLib.enumDataTransferType.ftpDataTransferTypeASCII

Can you confirm that these are the correct settings that i should be using for what i am trying to achieve?

Hello ..

What you are requesting goes beyond pre-sales support. Please purchase a license and things may look a little bit different.

Thank you.

Mat,

can you answer this question the for me.

The backup software only downloads the first 42 files, is this a part of the evaluation library and i need a license for it to download all the files?

Darren

Mat,

I have just purchased a license from you. The company is Building Software Limited.

Can you now answer my questions?

Hello ..

Thank you. I've replied in the other thread. We need more information as requested before.
