Re: Domains

Using Visual Studio 2005, put two text boxes and one command button on a
form and use this code. It will handle either a name or a numeric IP
address

Private Sub Button1_Click(B yVal sender As System.Object, ByVal e As
System.EventArg s) Handles Button1.Click
Windows.Forms.C ursor.Current = Cursors.WaitCur sor
'first determine if a numeric Ip address or a name
Dim txtSearch As String = "", Result As String = ""
If IsNumeric(Repla ce(Trim(Me.Text Box1.Text), ".", "")) Then
txtSearch = Trim(Me.TextBox 1.Text)
Dim host As System.Net.IPHo stEntry
Try
host = System.Net.Dns. GetHostEntry(tx tSearch)
Result = host.HostName.T oString
Catch ex As Exception
Windows.Forms.C ursor.Current = Cursors.Default
MsgBox(ex.Messa ge)
End Try
Else 'need to change the host name into a numeric IP address
Dim host As System.Net.IPHo stEntry
Try
host = System.Net.Dns. GetHostEntry(Tr im(Me.TextBox1. Text))
Catch ex As Exception
Windows.Forms.C ursor.Current = Cursors.Default
MsgBox(ex.Messa ge)
Exit Sub
End Try

Result = host.AddressLis t(0).ToString
End If
Me.TextBox2.Tex t = Result
Windows.Forms.C ursor.Current = Cursors.Default
End Sub
