I created an internet application.  I need a solution to have users log on and verify username and password using an internet database.  Can someone provide me code of how to do this!

An internet database is essentially just a normal database, nothing special. When you say internet application are you referring to asp? If so,

'This statement should be on all pages so that user cannot cache your URL and reenter without loggin in.
<% If Session("Authenticated")="NO" Then Response.Redirect("Login.asp")
End if
%>
.
....
...
...
<%
if request("Submit") = "Submit" then

Sql  = "Select * from Usertable where Username = '" & Request("Username") &"' and Password = '"& Request("Password") &"'"

Set Rst = Server.CreateObject("ADODB.RECORDSET")
Rst.Activeconnection = ' Put your connection here
Rst.Source = Sql
Rst.CursorType = 0
Rst.CursorLocation = 2
Rst.LockType = 3
Rst.Open

If Rst.Eof then
Response.Redirect ("xxxxx") ' Not a valid user, throw to some page
else
Session("Authenticated")="YES"
Response.Redirect ("xxxxx") ' Valid user, continue to some page.
End if
