问在使用TcpConnectionNew时,bound `():futures::future‘的特性不满足EN在开发多线程时,我们有时会需要返回子线程的处理结果,但不幸的是Runable接口是void类型没有返回值的。有人可能会想到用实例变量的方法实现此需求。实例变量的方式当然也是可以的,在其它文章中已经介绍过了,在使用实例变量时要特别注意,因为实例变量有可能会出现线程安全问题...
这里始终得不到newConnection,应该就是信号发送的主体可能出现问题。 同样的,后面也出现了相同的无法收到readyRead信号的问题。 connect(tcpServerConnection,SIGNAL(readyRead()),this,SLOT(ReadMyData())); 更改成如下问题同样得到了解决。 connect(tcpServerConnection,&QTcpSocket::readyRead ,this, &MainWindow::Re...
QTcpServer::newConnection是一个信号,当一个新的客户端成功连接到QTcpServer实例时,这个信号会被触发。它是QTcpServer类用来通知开发者有新的客户端连接请求到达的机制。 阐述newConnection信号在何时会被触发: 当QTcpServer实例调用listen()方法开始监听某个端口后,如果有客户端尝试连接到该端口,并且连接成功,new...

问无法捕获来自QTcpServer的newConnection()信号EN首先,我可以说您的服务器驻留在新线程中,而CServer...
Each server makes responses to the packets requesting a new TCP session after some duration proportioned to its workload. And, the dispatcher passes only the first response packet, while rejects the others. Finally the first-responding server takes charge of the TCP session. ...
新人求助~QTcpS..我在另外一台机子Telnet这个端口是通的,说明侦听是成功的,但是无法触发newConnection信号。。Qt 5.2相关的语句:server为指向QTcpServer的指针显示listen okh
,这个函数应该是为套接字跨线程设计的,像MFC中的CSocket一样QTcpSocket也是不能夸线程,在fmc中想让Csocket跨线程就得先分离套接字句柄再在线程中再绑定句柄以生成新的CSocket,Qt示例中也是这样搞的 把 socketDescriptor传入QThread 再在QThread中生成一个新的QTcpSocket。newConnection()是个信号 ...
Assume that you create a SQL Server 2014 Integration Services (SSIS) package that contains Open Database Connectivity (ODBC) connection. When you run the package, you will find that a new Transmission Control Protocol (TCP) connection is established and remains open until the process is terminated...
