Creating 'delfromdb.asp' page :

Create a new ASP page and name it 'delfromdb.asp'. Copy and paste the following code into it :

   <!--#include file="editme.asp"-->
   <html>
   <head>
      <style>
         body { font-family : Verdana; font-size : 8pt; }
      </style>
   </head>
   <body>

 <%
   Dim con, strDB

      ' URL
      strURL = Request.QueryString("del")

      ' Creating our Connection Object
      Set con = CreateObject("ADODB.Connection")
      con.Open strDB

      ' Now deleting the account
      con.Execute("delete * from all_pages where url = '" & strURL & "'")

      ' Telling the admin that account has been deleted
      Response.Write "<b>Account successfully deleted : " & strURL & " </b>."

      ' Done. Now release Objects
      con.Close
      Set con = Nothing

 %>
      </body></html>

Reviewing the code :

   <!--#include file="editme.asp"-->
   <html>
   <head>
      <style>
         body { font-family : Verdana; font-size : 8pt; }
      </style>
   </head>
   <body>

 <%
   Dim con, strDB

Same as earlier pages.

      ' URL
      strURL = Request.QueryString("del")

strURL receives the URL entered in the Form 3 of 'addtodb.htm' page.

      ' Creating our Connection Object
      Set con = CreateObject("ADODB.Connection")
      con.Open strDB

Creates the Connection object and opens the database.

      ' Now deleting the account
      con.Execute("delete * from all_pages where url = '" & strURL & "'")

Deletes the record in the database of the given URL.

      ' Telling the admin that account has been deleted
      Response.Write "<b>Account successfully deleted : " & strURL & " </b>."

      ' Done. Now release Objects
      con.Close
      Set con = Nothing

 %>
      </body></html>

Tell the user that the given URL has been deleted. Then release the objects and end the page.

On the next page we create 'search.htm' to create a Form to show users to enter keywords to search pages from our Search Engine database.
