Regular Expressions is one way.

Imports System.Text.RegularExpressions
....
Dim rx As Regex = New Regex("(?<1>microsoft.com)")
Dim mt As Match = rx.Match("http://www.whatever.microsoft.com")
If mt.Success Then
retval = mt.Groups(1).ToString
End If

There's decent pattern matching help in MSDN and Google.

re: Get Domain Name from URL?

Jack,

This gives you back the domain name.

Dim myUri As New
Uri("http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemuriclasshosttopic.asp")
messagebox.show(myUri.Host)

I don't not know a method to strip a domainname to smaller parts. There are
all kind of domainnames you know. (2 dots, 3dots, 4dots)

I hope this helps,

Cor
