Nerwork connect function

Hi every body,

I am new to Qt and now want to write a TCP client/server socket program in Qt.
Unfortunately when I use the connect funtion, it returns -1 even to make a connection to localhost.
Who know what the problem is?

Added after 36 minutes:

how can run a client and a server application on two different computer in a network?
Both the client and the server are c++ application which are wtitten in Qt but not with the QNetwork.

Since you are not using Qt for the network setup, why do you ask on this forum?

since this network code is a part of an application whic I have written in qt, thus I have to write this part in qt but I dont want to use Qnetwork,

Sure, but your problem is not in any code that uses Qt, right?
Why would you expect anyone to know what an unknown function is doing or why it is returning a certain value?

Consult the documentation of the API that you are using. It should have information about what the meaning of return values of its functions are.

Cheers,
