vb.net

hi,
How to check using VB.net application whether the devices like printer are connected to the system ?
.How can we check if NIC is present and is connected to network?
IP address alone is enough to connect to a host in the network ?
Anyone knows please help me.

For printers collection use:

Code:

---

System.Drawing.Printing.PrinterSettings.InstalledPrinters.Item

---

For IP address:

Code:

---

Dim ipHostInfo As System.Net.IPHostEntry = System.Net.Dns.Resolve(System.Net.Dns.GetHostName())
Dim ipAddress As System.Net.IPAddress = ipHostInfo.AddressList(0)

hi,
this gets the ip address ,thanks for it.
But my need is to know whether the NIC has connection with the network or not. And how to connect to a host in the LAN?

System.Net.Sockets - Ping to check for network activity, and connect to a host. Need further let me know.
