Thread running normally now. I was in the project which added a "tcpserver", used to monitor the connection and receive messages. In C # to call when the client "socket" shows the state is "already connected", but in C # where not receive data, "incomingConnection" function has not been called. If I use QT to use the DLL functions can be done, then, C # in the die. Is no event loop ah?
