Loading a cookie on Page_load (ASP.NET)

[Denna]

Hello, I'm having a little trouble with cookies, I can write one when I press a button using the following code:-

HttpCookie myCookie = new HttpCookie("MyTestCookie");
 
myCookie.Value = tbxLogin.Text;
Response.Cookies.Add(myCookie);
 

and I can retrieve the cookie (By pressing another button) using:-

HttpCookie getMyCookie = new HttpCookie("MyTestCookie");
getMyCookie = Request.Cookies["MyTestCookie"];
 
if (getMyCookie.Value != "")
{
lblName.Text = "Welcome " + getMyCookie.Value;
}
 

The problem is, I want to check if a cookie exists when the page loads up, if so, then I want to write the value (Which is just a persons name), into a label!!!

The problem is, when I try to use the second code snippet in the Page_Load(...) function, I get an error!!!

Could anyone point out where I stick the second code snippet, or, if I'm going about this the wrong way, has anyone got a few pointers!!!

Thanks in advance

Hi Denna,

If i am you, I will do this:

HttpCookie cookies = Request.Cookies["MyTestCookie"].Value;

if (cookies != "")
{
lblName.Text = "Welcome " + cookies;
}

Correct me if i am wrong. I do not have VS.NET with me now, using a notepad :)

Sorry Chua, it didnt work, I get two errors when I try to build the solution, as a note, I'm running Visual Studio 7, so that may be the reason!!! :)

Hi Denna,

Can you paste the 2 errors here? Is it a compile or run time error?

Thanks. Sorry for the trouble.

Hiya Chau, sorry for the delay, I had to go to bed, dreaming about cookies would you believe, anyway, it gives off 2 compile time errors:-

"c:\inetpub\wwwroot\index\WebForm1.aspx.cs(82) : Cannot implicitly convert type 'string' to 'System.Web.HttpCookie'"

and

"c:\inetpub\wwwroot\index\WebForm1.aspx.cs(84) : Operator '!=' cannot be applied to operands of type 'System.Web.HttpCookie' and 'string'"

'QUOTE: Thanks. Sorry for the trouble.'

Don't worry Chau, lol, I'm just over the moon someone is helping me with it, I really appreciate you using your time on this!!! ;)

I put your code in the part where, if you click a button, it's supposed to read the cookie (Though, my original code works fine here), I really want to read the cookie when the ASP.NET page loads up, and display the users name.

Hi Denna,

Hope this solution can help you. But there are many ways to do it. This is just an example. :)

Codes:

protected HttpCookie cookie;

private void Page_Load(object sender, System.EventArgs e)
{
cookie = new HttpCookie("MyTestCookie");
cookie.Value = "Chua Wen Ching";
cookie.Expires = DateTime.MaxValue;
Response.Cookies.Add(cookie);
}

private void Button1_Click(object sender, System.EventArgs e)
{
HttpCookieCollection cookieCollection = new HttpCookieCollection();
cookieCollection = Request.Cookies;

string retrieveCookie = "";

foreach(string str in cookieCollection)
{
retrieveCookie = Request.Cookies[str].Value;
}

if (retrieveCookie != null)
{
Label1.Text = "Welcome " + retrieveCookie;
}
else
{
cookie = new HttpCookie("MyTestCookie");
cookie.Value = "Chua Wen Ching";
cookie.Expires = DateTime.MaxValue;
Response.Cookies.Add(cookie);
}
}

Finally i had vs.net with me. Haha! Anyway please let me know if this is not what you want. This might not be the best solution. :)
