Hi Guys,

I am trying to send bytes over TCP/IP using the StreamWriter and/or the BinaryWriter.

I am so confused, and tried various other ways.

what I want to do:

send 1st data packet as a Long (47, 4, 0)
get a reply (automatic one)
then send long (001)

I can open a connection using the Client connect....

using Dim Client as new Net.sockets.TCPclient

then just send the packets as above!

Really could do with some help!

Cheers,

James

I am not experienced with TCP/IP but someone in the past tried to do something like you are trying to do and one problem is that TCP/IP buffered the data so that it did not get sent when we expected it to. I don't know the solution to that problem, but there are articles in this web site that might help.
