cf 2. tcpclient connect in thread with timer for timeout

I'm not sure what's direction take. I have not much experience with thread to solve my problem. For solve my problem, i'need an event that return state of connection if connection is established and an event that stop the thread that incapsulate tcpclient.connection to free resource and try another connection. I try this code to sample but don't work. I've posted my project sample.

I am surprised that there is not a timeout for connections, but apparently not. I am not experienced with sockets enough to know for sure, but you could try setting the send and receive timeouts, in case that has an affect. Probably not.
 
You could try doing what you described in your original question; that is, use a timer. It is not clear to me how your thread would resume after the connection attempt is aborted. I think what you need to do is to do an asynchronous connection. You could then wait on either the connection or the timer. I don't know how to cancel the connection attempt; perhaps that is not necessary. Other than that, I think an asynchronous connection would work.
