No. This site is not a free code-correction-service. If you have a proper question, then ask, but don't post requests for correction in this demanding tone!

Same goes here as the earlier one! too demanding!... you need to learn how to ask for help first and then post your queries.

correct this code

// Possible chance of null reference error. You should make a null check
Response.Cookies["backgroundcolor"].Value = "Red";
Response.Write(Request.Cookies["backgroundcolor"].Value);


HttpCookie mycookie = new HttpCookie("cookie1");
mycookie.Value = "some cookie value";


//100 days is too much for a cookie to expire
mycookie.Expires = DateTime.Now.AddDays(100);
Response.Cookies.Add(mycookie);


//Possible chance of null reference error
Response.Cookies["mycookiename"].Value = "mycookievalue";
Response.Cookies["mycookiename"].Expires = DateTime.Now.AddMinutes(15);


//This is not correct. Load the firstname from database, you are
// storing the query itself. ASP.NET
//is not going to execute this query for you.
//Sql Injection prone, use parameterized query
// Variable "Id" is not defined, from where this Id is coming??
Response.Cookies["visitordata"]["firstname"] =
  "select login from registerform where registerform.id='" + Id
 + "'";


Response.Cookies["visitordata"]["lastvisit"] = DateTime.Now.ToString();
if (Request.Cookies["mycookiename"] != null)


 //mycookievalue is undefined, you should create a string variable for this
 mycookievalue = Request.Cookies["mycookiename"].Value;
