C# Remote desktop sharing like teamviewer

Question

Hi,
I want to create a Remote desktop sharing application in C#.net.am using VS2010.
Actually I referred this link http://www.codeproject.com/KB/cs/RemoteDesktop_CSharpNET.aspx.
But still am not able to connect to remote system.
Is there any other way?
Or any socket programming will help me?
Can anyone help me?

Thanks in advance
