I am trying to protect a portion of a web site by allowing users to =
register a username and password & then login with those details, but so =
far I am having only marginal success. I am far from an expert on ASP =
programming, indeed the code I am using comes from "Sams Teach Yourself =
E-Commerce Programming with ASP" but it is ideally suited for my =
purpose.

In short, there are 3 .asp pages (register.asp, login.asp & =
checkpassword.asp - the code for each is below), a global.asa file was =
automatically created and by following the instructions in the book, I =
also created a small Access database called UserDB.mdb, which stores the =
username & password of each user when they register & also verify's =
those details when the user attempts to login again.

The DNS connection has been setup within FrontPage and I have verified =
that this connection works by clicking "Tools", "Web Settings" & the =
"Database" tab, highlighting the DNS connection & clicking Verify.=20

The problems seem to occur when I try to register a new username & =
password, for some strange reason the details I enter are not being =
saved in the database table, and to compound the problem further, if I =
register just a username, or a password but not both, the page simply =
refreshes itself with empty boxes instead of giving an error message to =
indicate that a "username" or "password" must be entered, which if I =
have read the code correctly on the "checkpassword.asp" page, should =
happen.

To further confuse the situation, if I manually enter a username & =
password into the database table and then attempt to click a hyperlink =
taking me to a "test.asp" page, with the INCLUDE FILE: , I am automatically taken to the =
login.asp, where if I enter the username & password that I manually put =
into the database table, it takes me to the selected "Protected" web =
page. In my mind that clearly shows the DNS connection is working but =
yet it won't store new registered details into the database table, which =
is extremely confusing.

If anyone can see what I may be doing wrong, or point me in the right =
direction, your help & advice will be greatly appreciated. As I pointed =
out earlier I am far from an expert, so any help you can give would be =
ideally suited towards a newbie mentality.

Below is the code for the three .asp pages:

I am trying to protect a portion of a web site by allowing users to register a username and password & then login with those
details, but so far I am having only marginal success. I am far from an expert on ASP programming, indeed the code I am using comes
from "Sams Teach Yourself E-Commerce Programming with ASP" but it is ideally suited for my purpose.

In short, there are 3 .asp pages (register.asp, login.asp & checkpassword.asp - the code for each is below), a global.asa file was
automatically created and by following the instructions in the book, I also created a small Access database called UserDB.mdb, which
stores the username & password of each user when they register & also verify's those details when the user attempts to login again.

The DNS connection has been setup within FrontPage and I have verified that this connection works by clicking "Tools", "Web
Settings" & the "Database" tab, highlighting the DNS connection & clicking Verify.

The problems seem to occur when I try to register a new username & password, for some strange reason the details I enter are not
being saved in the database table, and to compound the problem further, if I register just a username, or a password but not both,
the page simply refreshes itself with empty boxes instead of giving an error message to indicate that a "username" or "password"
must be entered, which if I have read the code correctly on the "checkpassword.asp" page, should happen.

To further confuse the situation, if I manually enter a username & password into the database table and then attempt to click a
hyperlink taking me to a "test.asp" page, with the INCLUDE FILE: , I am automatically
taken to the login.asp, where if I enter the username & password that I manually put into the database table, it takes me to the
selected "Protected" web page. In my mind that clearly shows the DNS connection is working but yet it won't store new registered
details into the database table, which is extremely confusing.

If anyone can see what I may be doing wrong, or point me in the right direction, your help & advice will be greatly appreciated. As
I pointed out earlier I am far from an expert, so any help you can give would be ideally suited towards a newbie mentality.

Below is the code for the three .asp pages:
