For starters, I will make a plugin command /xdmsend or something that opens a file open dialog and sends the file. After I have a working transfer I will, maybe, make it so that when u click on send file or when a file is sent is msn messenger you will get the custom download manager or something.

Well, good news! I figured out how to do file transfers and communicate between server/client sockets

Now, IMHO I should include some error-checking mechanism (CRC, MD5, SVF, or something else). Which one to use?

~Alex.

Again, which ever works best, although I think that CRC might be the easiest. Good job so far.

I just want to say that this sounds like an awesome plugin, and I will tell as many of my friends as possible about it when its done.
Im amazed over how far you have gotten in the making of this, alex.
You are, IMHO, a very talented programmer. I foresee your plugin(s ) and future projects will kick some good and fat ass.

I think I speak for just about everybody when I say "Good Luck!"

You don't speak for me! I say "Good job!" . Anyways, if you want I can test for you.

Thanks for the replies...

The plugin is not yet in a working stage. I need to implement a download manager dialog with the transfers...

Anyways I've got some help  from a friend on the net..

I have one more exam on Monday in Spanish, then I can work on this a lot more

For error-checking, I wil use zlib's error checking mechanism Adler32. CRC32 didn't work for some weird reason - crashed the whole thing so i dumped it. Works fine with Adler32. They are similar anyways...

EDIT: Also, CRC and Adler32 both generate 8-byte checksums, while MD5 generates 32-byte checksums. So, the "useless" data sent is kept to a minimum.

I will try to make the protocol AS SIMPLE as possible so that file transfers are AS FAST as possible. When I have a more detailed protocol description I will post it and request comments/improvements.

~Alex.

Development is going on nicely...

Working on the Server now. It will be a multi-threaded server (u want more than 1 file-transfer at one time right? ). If everything works as planned, it should be done in 1 week maybe?

Question for people that know winsocks:
If my socket listens on say port 1234, can it connect to more than 1 computer at the same time through the same port? Eg. do my server threads have to use mutexes so that only one server thread can send/receive data at a time?

~Alex.

Good job, sounds like your working hard.

I can't wait!

Don't flame me for being wrong, but I think you can only one connection for a port... (In other words, you can't connect to more than one computer using just one port)

BTW, this is going to be a great plugin

set the remoteport and localport of the new sock to 0, then accept it. you'll be able to have more connections
that's how you can in VB
