Read up on string manipulation in ASP.  Basically just search the string for things that look like web addresses.  Verify it, than manipulate it.

That's a lot of code.  'We' probably should use the replace function at some point.  I don't have the time sorry.  Take a look on google, it's out there somewhere.

The basic idea is:
 
userAddress=request.form("address")
 
response.write ("<a href="  & useraddress & ">" &  useraddress & "</a>")
 
 
You are simply writing a standard formatted link using the formfield value.

I think he was talking more along the lines of having a chunk of text like:

wefiwhfeiopwehf iphwfeih ihfwihewfpi hipfwepih www.drum-world.com fwihpwfe wfepiwef pijfwe wefpijwef

And then finding any hyperlinks and converting them to HTML

it's in VB.NET but you should be able to convert it to asp 3.0, all it does is search a string using regular expressions for a link and then puts the relevant tags around it.





If Not IsDBNull(desc) Then

            Dim temp As String = desc



            Dim
mc As MatchCollection = Regex.Matches(temp,
"http://([\w-]+\.)+[\w-]+(/[\w- ./?%&amp;=]*)?",
RegexOptions.IgnoreCase)



            For Each m As Match In mc

                If Not m.Value.Length > 40 Then
 
                &n bsp;  
temp = temp.Replace(m.Value, "<a href=""" & m.Value & """
target=""_blank"">" & m.Value & "</a>")

                Else
 
                &n bsp;  
temp = temp.Replace(m.Value, "<a href=""" & m.Value & """
target=""_blank"">Click here to visit link</a>")

                End If

            Next



            Return temp

        Else

            Return String.Empty

        End If

Mart did a good article on regular expressions in .NET at DevJunkies.com. Most of it is still applicable to ASP. I needed to do a task cleaning some text in .NET and used WWF code with a few tweaks. Very simple stuff.

Just read the article for a good overview.
