Send and Receive data

I need to know how I can comunicate two applications running in two diferent computers.

Theese computers are now joined by a LAN and both applications must work at the same time and the data must be sended in real time.

If you know something about this, please write me. I'm very worried.

Thanks a lot.

Take a look at the winsock control. I think it will be of help.

Thanks a lot, this control is just I need.
I'm learning more about this by VB's help, and I think this is the correct way to solve the problem.

Good bye.
