My problem is that.
I need to develop a programming connect to server to get Video, but server request UserName, PassWord. I don't know how to slove this. I use QtcpSocket
thanks so much

Without knowing the transmission protocol nor your code there is nothing we can do for you.

thanks
this is my code

void Hello::connect(char* serverName, int port){
QTcpSocket socket;
    socket.setProxy(QNetworkProxy(QNetworkProxy::DefaultProxy, serverName,port,"userName","passWord"));
//socket.connectToHost(serverName,port);
if(socket.waitForConnected(6000)==true)
{
qDebug()<<"Successfully";
}
else{
qDebug()<<socket.errorString();
return;
}

void Hello::connect(char* serverName, int port){
QTcpSocket socket;
    socket.setProxy(QNetworkProxy(QNetworkProxy::DefaultProxy, serverName,port,"userName","passWord"));
//socket.connectToHost(serverName,port);
if(socket.waitForConnected(6000)==true)
{
qDebug()<<"Successfully";
}
else{
qDebug()<<socket.errorString();
return;
}

To copy to clipboard, switch view to plain text mode 

if we don't have userName,passWord everyone can connect and get my private data?
thanks

Still not enough information. What kind of protocol do you want to use? Http, Ftp, Nntp, ... ?

We will not fix your code. You didn't provide enough information. Even if you did, we would still not fix your code but instead help you fix your own code. But this is meaningless since you don't even know what you are doing...

i think that protocol is FTP

Then I think you may want to use some higher level class such as QNetworkAccessManager or QFtp instead of QTcpSocket as I think you know FTP protocol requires at least two sockets.

TCP

This is transport protocol. We are asking for application protocol.
