I have an application which accepts the connection and recieves the messages from the client and holds it in a character buffer and I have created a VC++ windows application form and created a text box for that.Now I wanted to reroute the messages that I received on the buffer to be displayed on the Text box.Please help me as I am new to .Net platform.Here is the complete code......

Here is the code for the VC++ windows application form.I have the server socket code here which accepts the connections and reads the data from the client and puts it in a buffer.Now I want to redirect this to a text box.
