hi every one,
i'm developping a server application using vb.net and i'm facing a problem. in fact i have a hudge data to send to the client via the socket so i use a loop to divide the data and send eatch part the problem is that when i proceed with the sending the socket send me only few peaces of the data and loose a big part of it. i tryed to flush the buffer after each sending but i didnt find how to do it so i used a system.threding.thread.sleep between each socket.send. it wors when i don't have hudge data but it blocks my server when the number of paquets increases. is there a solution that would replace the .sleep one without blocking the application??

> send me only few peaces of the data

The Send method can return without sending all of the bytes you provided to it. You need to examine the return value and loop if it is less than the total number of bytes you wanted to send.

There is a similar issue with Receive. Receive reads the bytes from the TCP/IP stream as them come in, which might not correlate exactly to invocations of Send on the other side.
