You could use microsoft winsock control to achieve this. There is one good code sample in this url http://www.a1vbcode.com/coderedirect.asp?type=application&ID=341

You need to send/receive binary data to transfer pics and exe files.

Set your InputMode to comInputModeBinary. And then pass Byte arrays to the Output method, and also use a Byte array when calling Input in your receiver application.

So....

You're saying that you want to send the name of the file & the size of the file as a header prior to actually sending the file itself?
How about you send that in text mode, and then, once you get a response from the client that it's received the header, switch both server and client to binary, and then push the file itself?
