Code Title: Auto-linking
Description: How would you like to have every instance of an http:// auto-hyperlink itself to the URL address that follows it? Well, here is a killer little function that will take every one of those that it finds in a string and sets up the hyperlink for you! Cool, eh? Copy and paste this snippet as-is into your editor: ------------------------------------------------------------------------- <% Function LinkURLs(strInput) iCurrentLocation = 1 Do While InStr(iCurrentLocation, strInput, "http://", 1) <> 0 iLinkStart = InStr(iCurrentLocation, strInput, "http://", 1) iLinkEnd = InStr(iLinkStart, strInput, " ", 1) If iLinkEnd = 0 Then iLinkEnd = Len(strInput) + 1 Select Case Mid(strInput, iLinkEnd - 1, 1) Case ".", "!", "?" iLinkEnd = iLinkEnd - 1 End Select strOutput = strOutput & Mid(strInput, iCurrentLocation, iLinkStart - iCurrentLocation) strLinkText = Mid(strInput, iLinkStart, iLinkEnd - iLinkStart) strOutput = strOutput & "<a href="""&strLinkText&""">"&strLinkText&"</a>" iCurrentLocation = iLinkEnd Loop strOutput = strOutput & Mid(strInput, iCurrentLocation) LinkURLs = strOutput End Function strUnlinked = "http://LINE9.com rules! <br>" & vbCrLf strUnlinked = strUnlinked & "http://pdxpc.com sells great computers!<br>" & vbCrLf ' Here is the before text: Response.Write "<b>Original Text:</b><br>" & vbCrLf Response.Write strUnlinked Response.Write vbCrLf & "<br>" & vbCrLf & vbCrLf ' Here is the text after it gets automatically hyperlinked to itself: Response.Write "<b>Text After Linking:</b><br>" & vbCrLf Response.Write LinkURLs(strUnlinked) %> ------------------------------------------------------------------------- |
