Hello,
I work at my school, I have a client-server application in C # with Visual Studio 2010 and I have my first client 1 that connects to server. but now I have a problem to connect a server to another client 2 in a VM (Virtual Machine: Virtual Box Windows 7).
Client 2:
* It should be the server connects to the client 2?
* The server sends a message to the client that son located in a virtual machine?
* After sent, the server received a confirmation message from client 2?
So it remains to create of client 2 code that receives a message from the server and client 2 sends a confirmation response to server and client 1?
Please find attached client / server code.
Very thank you in advance and regards.
thank you
