How to implement cookies to save your ID and Password (ASP.NET)

By -
"Cookies can be defined as a small text files that are created by Web Server and saved by Web Browser on Client's Machine"
However, if clients machine has disabled 'Cookies' , the script to create & store cookies will lose its effect.


Here, we are going to create a LOGIN page, that ask user to enter it's ID and PASSWORD. Also, if user selects, 'Keep me Signed in' for next visit, we'll save its ID & Password
Following are the name of controls on our LOGIN Page:


1. idlbl for Your Id Label
2. idtxt for textbox where User ID will be entered. Also set its AUTOPOSTBACK property to TRUE
3. passlbl for Password Label
4. Passtxt for textbox where password will be entered.
5. loginbtn for LOGIN button

Write following declaration statement in General Section
Dim uid as HttpCookie

Write following code at LOGIN Button
if checkbox1.chcked=true then
    uid = New HttpCookie(idtxt.text)
    uid.value=passtxt.text
     Response.Cookie.Add(uid)
     Response.Cookie(uid).Expires=DateTime.Now.AddDays(5)
end if

Write following statement at page_load event of LOGIN Page
   uid=Request.Cookies.Get(idxt.text)
   if Not uid Is Nothing Then
      passtxt.text = uid.value
   endif

That's all what we need to maintain cookies with our ASP.NET Page. For Further Queries and Suggestion, please  Leave a comment.

Watch out for Next Tutorial Tomorrow.

Thanks & Have a great Programming Day, AartiAkhilesh Rathore
