Winsock / TCPClient/ Sockets question??[Closed..Asking worng]

[Static]

I have an app in VB6 that queries servers for info...

I want to try to do this in VB.net (im am teaching myself vb.net)

I know I could use winsock ..but have read about tcpCLient and systems.socket (or something like that)

How do I "add" either of these in? which should I use? Help!

I cant seem to find either in references or controls? am I missing something?

thanks

ANyone?

I have tried this:

Dim TCP as New System.Net.Sockets.TCPClient
TCP.Connect(TextBox1.Text, 7788)


But I cant seem to connect...any IP I use refuses it?

ERROR:
"An unhandled exception of type 'System.Net.Sockets.SocketException' occurred in system.dll

Additional information: No connection could be made because the target machine actively refused it"

Help??


Another Question:

How do u use the TRY / Catch?

I want to catch the error of no response from server..MSGBOX..then....exit out of the sub to allow a new IP to be entered?

If you want to trape an error use this

try
' your code

catch x as exception
msgbox x.message
end try
