Hi everyone!!!
I´m looking for a simple solution to "listen" a device with a TCP/IP connection. I have a camera taking pictures to products and sending via TCP/IP data: calculations, positions, etc.
I need to send commands to the camera too. I've seen many examples that show TCP/IP chats, but didn't work on my solution.

Best regards.

What I have tried:

I've used others programs (Hyperterminal, Hiperway, etc) to send and receive data and they work, now I need to code it in my proyect (vb.net).

You can go to the camera manufacturers website and see if there are any API documentation and examples available. PTZ commands for IP Camera's are often sent via HTTP, the ISpy website has a nice listing of commands.

In this case, OMRON has developed its own controls (VB.NET) almost 10 years ago and has not updated them since framework 3.5 version. The controls have little margin to receive info, so I need to go further.
I'm looking for a very simple example to receive data and send commands, I have not managed to do it (probably due to my lack of experience in VB.NET code). Any suggestions, code example? Thank you.

Google will find you many code samples of TCP/IP client server.

I have reviewed many examples and something I will be doing wrong. Do you have a simple example that works?
Thank you.

See tcp ip sample code - Google Search[^]. As we have no idea what language you are using or what "something I will be doing wrong" means.

You can refine the above search to find VB.NET samples.

Sure! Thanks, I'll continue searching.
