Hi,

If the connection succeeds "connected":https://qt-project.org/doc/qt-5/qabstractsocket.html#connected signal is emitted.
You can connect this signal to your slot.

also can check by

@if (socket->state() == QAbstractSocket::Connected)@

Thanks for the reply..

I am using
if(socket->state() == QAbstractSocket::ConnectedState)
to check but it is not working..

What is the state value returned ?

anmol2701

if i use

if(socket->state() == QAbstractSocket::ConnectedState || QAbstractSocket::ConnectingState)

it always returns true

Of course the statement below is always true:

@if(socket->state() == QAbstractSocket::ConnectedState || QAbstractSocket::ConnectingState)
@

as QAbstractSocket::ConnectingState is certainly greater then zero.

You need to change the statement to

@if((socket->state() == QAbstractSocket::ConnectedState) ||
(socket->state() == QAbstractSocket::ConnectingState))

@

Thanks all for the reply..

First of all i am checking socket is connected using

  if (socket->state() == QAbstractSocket::UnconnectedState)

it is working fine, then i add

  socket->connectToHost(server->text(), port->value());

after this i want to know is it conncet or not??

Moreover, I try to use this

   if (socket->state() == QAbstractSocket::connectedState)

But it is not working?

Could you please guide me?

If you still have trouble post your code

Thanks!
It works..
I simply check it using condition
if(!socket->waitForConnected(1000))
{
//code
}
