i was thinking of making a program that coonects to a ftp server so people can d/l and upload programs. is there any examples around that i can look at?

i'am not sure how to make it so people can upload files and see the files on the server to d/l

i thought i read some where it depends on the ftp server s/w so there might be problems or something.....


thanks

You might have a look at one of the example scripts of the vdsipp.dll... there is a ftp-client example included

you can take a look at the ftp example that comes with VDS 5.

Depending on the type of ftp server the output of the file listing is different. Depending on the type of ftp server you will get multiple different formats returned to you. This is the reason many ftp programs like CuteFtp, WS Ftp, etc. allow you to choose from a list what type of Ftp server it is - so they can show you the file listings correctly.

The only proper way to account for this is to replicate what cuteftp, wsftp and others are doing by finding the appropriate file listing format and having your program deal with it.

Thankfully many ftp servers use a very similar format but there are a few ftp servers which like to use their own. For instance you may get one ftp server that lists the files like this:

FILE TYPE| FILE NAME | SIZE | PERMISSIONS | DATE

and another may list each file like:

FILE TYPE | FILE NAME | PEMISSIONS | SIZE | DATE

where it moves the field type around, some may start by giving the the permissions first and then the type of file, or some may not even tell you the type of file it is (directory, link, file).

You noted 'what you can do to fix the problem', it's not a really a problem but an issue that requires more work to account for the many file listing formats available.

ok i think i follow you but:

You can give the user the option to choose what type of filelisting it has. Take a look at your ftp program and you'll see they give you the option as well. No there are not just these 2 types, there are well over 30 different formats.

[tim6389]

i found where it lets you selected what type BUT i don't see what commands its using for the diff types...


if ya follow what i mean

[tim6389]

well i can connected to the ftp server BUT it don't show the files or folders in the "site" window

the example i'am using is vdsipp03 the ftp example.dsc

any tips would be great

thanks

Make sure the ftp server you are connecting to is FTP and not TFTP there is a difference. The list on the right after connecting should show something if the server/client logged in correctly. Make sure you are using the right user/pass and that you have permission to view directories. If you're logging in as anonymous it may not let you view files/dirs.

[tim6389]

yea i found the problem i did a type oooo


i think i got it working


thanks for your help

Permissions do not necessarily have to be numerical. They can also be listed like: rxwxxxr etc. Also most file sizes reported from ftp servers are in bytes thus no period will be in the file size.
