Need suggestion regarding TCP/IP and Ethernet

Hi,
I have an app that is an interface to an electronic system and the connection between the system and my app is through LAN(Ethernet) using TCP/IP style and trough a network.
Actually I am new to this QT.I am working on QT4 windows XP. My problem is how to communicate on LAN using TCP/IP. I am not able initiate this. I want to know that whether is there any class in QT to do this or I have to write any special low level class to access the eternet and TCP/IP to communicate.Please if possible post any sample code link regarding this problem.
Please suggest me how to initiate and proceed.

Thanks for your valuable suggestions in advance.

Take a look at QTcpSocket. You can use Qt Assistant, and Qt Examples & Demos to find any examples and documentation about QtNetwork module.

Thanks for your reply.
