You need to make sure your TCPClient is connected to a remote host first.

hmm the connection is already connected, still the message cannot send out to the server. my server is using java

Could you use winsock to communicate instead? Or can winsock only communicate with another winsock?

[longdexin]

hmm sorry what is winsock? i just started learning Vb.net still very new to the VB.net

[benmartin101]

Winsock is used for server/client programs to send data to one another. When you say java server, you talking about chat server in java? I'm not sure if it has to be a vb server for it to work.
