Can you guys please help me here how to keep the cookie value same even if i click homepage again. Cheers, Shilpa.

Is the default.aspx is what you are calling your homepage?

If this is so then each time you load the page you create an unique id (string uniqueID = System.DateTime.Now.Ticks.ToString()), now since there will be always a time difference between two different page loads you will always have a new uniqueID and hence a new cookie value. That part of your logic needs changing.

try this

this is in vb form  

Response.Cookies("HttpBrowserCookieCheck")("data") = strVisitorID.ToString
Response.Cookies("HttpBrowserCookieCheck").Expires = DateTime.MaxValue

 i am not sure c# whether correct or not but you can try it

Response.Cookies["HttpBrowserCookieCheck"]["data"] = strVisitorID.ToString;
Response.Cookies["HttpBrowserCookieCheck"].Expires = DateTime.MaxValue;

hello,

Sorry i did not understand what i need to do, can you elobrate please

Cheers, Shilpa.

Response.Cookies("HttpBrowserCookieCheck")("data") = strVisitorID.ToString
Response.Cookies("HttpBrowserCookieCheck").Expires = DateTime.MaxValue

 i am not sure c# whether correct or not but you can try it

Response.Cookies["HttpBrowserCookieCheck"]["data"] = strVisitorID.ToString;
Response.Cookies["HttpBrowserCookieCheck"].Expires = DateTime.MaxValue;

i mean you use the method directly assign the value and expires date  that i given to you is more better than the one you use

            // Create cookie object
            HttpCookie cookieCreate = new HttpCookie("HttpBrowserCookieCheck");
            // Set the cookies value
            cookieCreate.Value = strVisitorID.ToString();
            //Set the cookie to expire in 20 minute
            DateTime dtNow = DateTime.Now;
            TimeSpan tsMinute = new TimeSpan(30, 0, 20, 0);
            cookieCreate.Expires = dtNow + tsMinute;
            // Add the cookie
            Response.Cookies.Add(cookieCreate);

change to 

Response.Cookies["HttpBrowserCookieCheck"]["data"] = strVisitorID.ToString;
Response.Cookies["HttpBrowserCookieCheck"].Expires = DateTime.MaxValue;

I have do a lot of testing to the method you use it is not work very well, sometimes it's work sometime not work

the method I given to you i have tested already it is 100% works.

Hello,

I am new to c# so please bear with me, I have done as suggested by you. But the value of visitor id is changing when i go back to defaultpage (homepage)

551sctn5633089470832658976 - VisitorID value when Defaultpage first loaded
551sctn5633089471011414696 - VisitorID value when i click on homepage.

My question is how to retain this First visitorID value(551sctn5633089470832658976) and use it till the user leaves my website. Please help.

Cheers, Shilpa.

ok before you create a cookies to visitor first you do a check whether the cookies is exist or not if the cookies is exist then you don't need to create cookies to the visitor already.

algorithm

if ((request["cookiesName"]["datafield"]==null) || (request["cookiesName"].expires<=now))
{
response["cookiesName"]["datafield"]=newid;
response["cookiesName"].expires = date;
}else{
DO NOTHING
}

try this algorithm

Many thanks for your reply, i have done this and still i get different values, I dont understand do you have any better idea. I just need one unique visitorid for each visitor so that i can link with shopping cart.

dcw0td45633089592297426436

ok i show you what i have done for my client website

Private Function getIDFromCookies() As String
        If IsNothing(Request.Cookies("cart")) Then
            Response.Cookies("cart")("data") = System.Guid.NewGuid().ToString()
            Response.Cookies("cart").Expires = DateTime.MaxValue
        End If

        Return Request.Cookies("cart")("data")
End Function

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        If Not IsPostBack Then
            getIDFromCookies()
        End If
End Sub

 I just this few line codes only i have done all what you want to do. may be you can try it this code.

for what i am doing is i give the visitor one unique id and this unique id i have store into cookies, when ever i need the id i just call the function again

ok i exlaining the code that you given to me. I will put comment at there. it is because i have found the reason why you always get new id.

just read through all the comment i put within your code then you will know why

//then you check the cookies whether it is exist or not.
//if the cookies is null or expires

if ((Request.Cookies["HttpBrowserCookieCheck"]["data"] == null) || (Request.Cookies["HttpBrowserCookieCheck"].Expires <= DateTime.Now))

{
// you create new cookies the the cookies is not exist
//the data of the cookies is the combination of first 8 values of the session id follow by the current datetime

Response.Cookies["HttpBrowserCookieCheck"]["data"] = strVisitorID.ToString();

// the expires datetime is Max Date value the server espect to give
Response.Cookies["HttpBrowserCookieCheck"].Expires = DateTime.MaxValue;

}

//Here you create another cookies
HttpCookie cookieCheck = null;

// Request cookie from client's browser

solution is you have do twice with the same job try to eliminate the redudent job, may be you can use the code that i provide to you and do some changes. i am not recommand to use HttpCookie to handle the cookies. directly request the cookies. I have done a lot of test and project i found that the HttpCookie something didn't get the value although the cookies is found and has been assign by you. therefore the code i given to you is not using httpcookie to communicate with the cookies. i just use direct method to get the value from cookies by using request method

Whatever way you use for generating the cookie value, if that is (the logic for generating an unique id for the cookie) is in the page_load event, which by the way is supposed to fire every time you visit the page, you are going to get a new value for the cookie.
