Receive file sended with TransmitFile()

[pedro00pedro]

Hi Everybody,

The MSDN shows how to use the API TransmitFile() to send a file over a conneciton-oriented socket.. but it does not show you how to receive it!

Is it done with the recv function or is it done in any other way?

I want this becouse I'm making a chat program. By now it is a frame with a menubar with two (useful, there are more non-useful) entries. Both options creates a child window, but server option sets up a server, and client options conects to a server.

I'm a bit strucked in the function of sending and receiving files. So any help is wellcome

AFAIK, you can use receive() function to receive file data. The TransmitFile() is just an optimized sending function in sender side.

Ok, but another question, Is there a function to know when it's a file and not text? and How to rebuild the file on the receiver side?

You have to build a mechanism (protocol) so the receiver knows received data has to be saved into file.

To rebuild the file, just save all receive data into file, but as i mention above, you have to build a mechanism how to transfer the file. The good example may be FTP protocol.

I forgot to tell you. There is no function to know received data is a file data or just a text.
I suggest you to see RFC959 (File Transfer Protocol) as an example.
