You probably need to first understand how to develop a form in asp.net so that you can store the form's details in a database.
This is a fundamental principle for asp.net development, and I would recommend reading through some tutorials on the basics first. Once you've got those down pat, you will find that developing your own email validation solution will be pretty simple.
I recommend the following site for a start: http://www.w3schools.com/a
I hope I haven't misunderstood your last comment and am telling you how to suck eggs. If I have, I apologise.

I program in C# and ASP .NET for a living. I'm not offended. Nobody really know who their talking to at EE. Anyway I have email validation worked out just looking for a way to make the one-line-link work like other sites do. For instance, to place a request to Arin.net I would do the following:
System.Diagnostics.Process
I just not sure how to accomplish the same effect with an ASPX page.
Here the whole aspx page (Internet Explorer -> View -> Source) to give you an idea:
As you can see there are two textboxes and one 'Logon' button that clients normaly use.
1. <input name="Email" type="text" id="Email" style="width: 164px" />
2. <input name="Password" type="password" id="Password" style="width: 164px" />
3. <input language="javascript" onclick="if (typeof(Page_ClientValidat

So do I understand in that you would like to be able to populate the login details based on a hyperlink?
ie if you gave me the url 'http://www.mywebsite.com/
Well to populate the form variables (lets say they are txtUsername and txtPassword) you would use something like this:
Page_Load(object p_sender, EventArgs p_args)
{
if (Request.Querystring["user
{
string username, password;
GetUsernameAndPasswordForU
txtUsername.Text = username;
txtPassword.Text = password;
}
}
Now if you want to press the submit button (lets says its called cmdLogin) then it depends when you would like it to be pressed. You could simulate the button being pressed in code behind by calling the event handler for the click event:
cmdLogin_Click(null, EventArgs.Empty);
Or if you wanted to show the user the page and then press the button you would need to use some javascript (I don't know off the top of my head how you would do this).
But if all of this is to automatically log someone on from an email, you may just find it easier to have a page that accepts some sort of user identity token, and then invoke the same authentication routines that your login page uses (say FormsAuthentication), and skip the whole populating the login page controls.
Ex: You can link complete http://localhost/myweb/com
exid in the database ,
http://localhost/myweb/com
when you send emai complete for user, you can send string complete + exid in database, and when user try it, it rollback and tick in database, signal complete.

Websites that use this registgration method want to confirm that the email address that you've supplied is a real email address. Sometimes they also wan't to confirm that a real person is signing up.
To acheive this the system will generate a unique id to associate with your registration information. This information is then probably persisted to a database table. The system then will generate an email that contains a link and will send this email to the email address you supplied earlier. The link/url embedded in the email will contain the unique identifier (I've seen numbers used as well as GUID's)
Example:
http://www.mynewsite.com/r
(If the email is a HTML formatted email, you may not see the unique identifier or the url at all since a lot of sites use this form "click <a href="http://www.mynewsite
When the website receives this request, it uses the unique number to find your registration information that you entered earlier and marks the data as being confirmed (since you have confirmed that you received the email, and have clicked on the link).
