cookies question

how do i create cookies that endure forever? and how to read them? i tried the following:

Code:

---

DateTime date = new DateTime(9999, 12, 20);
HttpCookie userCookie = new HttpCookie("user", "xxxxxxx");
HttpCookie pwCookie = new HttpCookie("pw", "xxxxxx");
userCookie.Expires = date;
pwCookie.Expires = date;
Response.SetCookie(new HttpCookie("user", "xxxxxx"));
Response.SetCookie(new HttpCookie("pw", "xxxxxx"));

---

and then in another page tried to load it

Code:

---

Label1.Text = Request.Cookies["user"].Value;
Label2.Text = Request.Cookies["pw"].ToString();

---

but i get a error when a object doesnt exist..what am i doing wrong?

tks

Try something like this:

VB Code:

'writing to the cookie
            Dim ckInfo As New HttpCookie("MHCPrivate")
            ckInfo.Values.Add("Username", txtUsername.Text)
            ckInfo.Values.Add("Password", txtPassword.Text)
            ckInfo.Values.Add("LastVisit", Now.Date)
            ckInfo.Values.Add("RememberMe", chkPersist.Checked)
            ckInfo.Expires = DateTime.MaxValue 'MaxValue is pretty much Forever
            Response.AppendCookie(ckInfo)
 
'reading from the cookie
            Dim ckInfo As HttpCookie
            ckInfo = Request.Cookies("MHCPrivate")
            'You might add some error handling here to make sure the cookie is not nothing
            txtUsername.Text = ckInfo.Values("Username")
            txtPassword.Text = ckInfo.Values("Password")

tks thu i had already discovered a way of doing it..but i am facing a problem that i think that has nothing to do with cookies..
i have a page called Log.aspx which has a label that says the nick of the person logged in. then i have another page called Login.aspx. the Login.aspx has a textbox to put the nick and another to put the password and a LOGIN button. if i login and go to the Log.aspx it shows the nick..now if i go to the Login.aspx as it detects the cookies the Login button will be replaced with a LogOut button. when i click it and go to the Log.aspx it shows no nick now..but now if i go back to the Log.aspx it will still show the button to Log Out..what am i doing wrong?

LOGIN.aspx
ON_LOAD

Code:

---

if (Request.Cookies["WebLog"] != null && Request.Cookies["WebLog"]["User"] != null) {
nickTxt.Text = Request.Cookies["WebLog"]["User"];
pwTxt.Text = Request.Cookies["WebLog"]["Pw"];
nickTxt.Enabled = false;
pwTxt.Enabled = false;
LogButton.Text = "Log Out";
}

---

Code:

---

private void LogOn_Click(object sender, System.EventArgs e) {
if (LogButton.Text == "Log Out") {
Response.Cookies["WebLog"].Values.Clear();
} else {
if ((nickTxt.Text == "xxx" && pwTxt.Text == "xxx") ||
(nickTxt.Text == "xxx" && pwTxt.Text == "xxx") ||
(nickTxt.Text == "xxx" && pwTxt.Text == "xxx")) {
Response.Cookies["WebLog"]["User"] = nickTxt.Text;
Response.Cookies["WebLog"]["Pw"] = pwTxt.Text;
Response.Cookies["WebLog"].Expires = new DateTime(9999, 12, 25);
}
}
Response.Redirect("Log.aspx");
}

---

the Log.aspx page code i think doesnt need to be shown as it is irrelevant. note also that here i changed the nicks and respective passwords to xxx.
you can check if u want the page at:
http://localhost/213.228.157.144/Log.aspx
http://localhost/213.228.157.144/Login.aspx
(user VB, pw FORUMS)

I got 404 errors on those pages even after i removed localhost. Maybe its not refreshing try setting an else in there to set it back to login if the cookie is missing.

http://213.228.157.144/HP/Log.aspx
http://213.228.157.144/HP/Login.aspx

sorry :rolleyes:

i will reboot back in 3min

back

Did you change something? It always says Login for me. For testing you sohuld have a link from the log page back to login.

i think it was because i was changing url thru IE gay so that was happening that "bug"

tks anyways!

hmm didnt see it well..it has the error in the same way..go to the page, login, then in the main page go to LogOut, then log out and then it will appear to u to LogOut when it should appear to login! but if u close IE and open it it will show login!

I don't see any LogOut on the log page?

tks its working now..the logout was the "carregue aqui" that is in bold :D i made it by puting the cookie expire date to DateTime.Now..using the Cookies.Remove(myCookie), Cookies[myCookie].Values.Clear() and Cookies.Clear() wasnt working i still dont understand why because in another project was working great :rolleyes:
