Next step is to start Client Socket Program. When you finish coding the program, First you have to start Server Socket Program, then you will get the DOS screen with a message Server Started. Click the following link to see in detail of Client Socket Program. When the client start its get connect the server and send requests, and also receive the response from Server. The Client Socket Program is a windows based application. Click the following link to see in detail of a Server Socket Program. Here the Server listening for the client's request, and when the server get a request from the Client, Server sends the response to Client. Here Server Socket Program is done through a Console based VB.NET application. In the above picture shows the communication interfaces. In the following section we are going to communicate a Server Socket Program and Client Socket Program through VB.NET using TCP/IP Communication. There are two types of communication protocol use for Socket Programming TCP/IP ( Transmission Control Protocol/Internet protocol ) Communication and UDP/IP ( User Datagram Protocol/Internet protocol ) Communication. Once the communication is established, the Server and Client can read or write their own sockets.

VB.Net socket example Server Program: A |HREF^Server Socket Program| running on a computer has a socket that bound to a |BLBS^ |Port Number|BLBE^ | on that computer and listening to the client's requests.Ĭlient Program: |HREF^Client Socket Program| have to know the |BLBS^ |IP Address|BLBE^ | ( Hostname ) of the computer that the |HREF^Server Socket Program| resides and the |BLBS^ |Port Number|BLBE^ | assign for listening for client's request. A Server Socket Program ( Server ) and a Client Socket Program ( Client ).

We need two programs for running a socket program. A Socket is an End-Point of To and From (Bidirectional) communication link between two programs (Server Program and Client Program ) running on the network.
