Retrieving a webpage source HTM and checking for a string thereinL?

[me]

Hi all,

Can anyone give me any pointers on how to do the following in VB.NET?

Basically, I want a procedure that will take a web URL and a string as
parameters, e.g. www.microsoft.com and 'Bill Gates'

I want the procedure to pull that page from the web, check for the existence
of 'Bill Gates' and return either true or false depending on whether or not
the string can be found.

I suppose all I need to know is - what is an effecient way to pull the HTML
source from any URL?

Help appreciated

How about this?

Private Function FindBill as Boolean

Dim hreq As HttpWebRequest = _
HttpWebRequest.Create("http://www.microsoft.com")

Dim hres As HttpWebResponse = hreq.GetResponse
Dim sr As New StreamReader(hres.GetResponseStream)
Dim tmpRes As String = UCase(sr.ReadToEnd)
sr.Close()
hres.Close()

If tmpRes.IndexOf("Bill Gates") >= 0 Then
Return True
Else
Return False
End If

End Function

Check out the function at
<URL:http://dotnet.mvps.org/dotnet/code/net/#InternetLoadFile>. You can use
'InStr' to check if a string contains a certain substring.
