1. That you want to use a physical path to the database.
2. That you use the Access driver, your database is named myDB and the path is on the E drive.
3. That the table in your database is named myTable, one field is named email and that the field in the form is named textbox1.

<%
Set Conn = Server.CreateObject("ADODB.Connection")
'assumption 1
FilePath = "E:\database\myDB.mdb"
'assumption 2
Conn.Open "Driver={Microsoft Access Driver (*.mdb)}; DBQ=" & FilePath & ";"

'assumption 3
sql = "DELETE * FROM myTable WHERE email=" & Request.Form("textbox1") 
Conn.execute(sql)
Conn.Close
%> 

This example is for using query strings and makes many of the same assumptions. Again, make the necessary changes.

1. That you want to use a physical path to the database.
2. That you use the Access driver, your database is named myDB and the path is on the E drive.
3. That the table in your database is named myTable, one field is named email and that the query string is named email.

FilePath = "E:\database\myDB.mdb"
'assumption 2

'assumption 3
sql = "DELETE * FROM myTable WHERE email=" & Request.QueryString("email") 
Conn.execute(sql)
Conn.Close
%> 

Now go find out how to add or edit a record the same way.

There are a few different options in building a DSN-LESS connection to your database. To get a look at them all, check out the connection page.
