II- How can i make application [u]doesn't allow non-member users</u> to enter member areas?

I am waiting for your help friends.
Thanks a lot!

You have to use the authentication (either Forms or Windows) to force the user to login

This can be done using the WebConfig file and couple of login controls available in VS2005 or VWD2KEE

Here is the sample for Forms Authentication in WebConfig file

<authentication mode="Forms">
   <forms name="AuthCookie" loginUrl="Login.aspx" defaultUrl="Home.aspx" timeout="10" />
  </authentication>

<authorization>
   <deny users="?" />
</authorization>


Try to include the login controls over a new ASP.net Page

To answer your first question, cookies are not the same as sessions. Rather cookies can be used to implement sessions. In order to implement sessions for a given website, your web server must be able to identify each HTTP request uniquely and map it to a session. A session ID can be stored in a cookie, or a little text file, on each client that hits the website.

HI ,
To make u clear , If u have 2 pages and want to share variable between these 2 pages .U can use session.
eg
session["username"] =" "raj"

then in second page u can get the values from session by

string name= session['username']

Once stored in session .It can be retrieved from any page. But obly for single user.

cookies are a small file in users machine. we can store some small information in cookies.So that if next time the user visits from same machine.we can tell , that the user is already visited our site.

Thanks, but i have done it before and it did not work :(
are you sure when we want to get value from session we should put attribute name among ' and '? (string name= session['username'])
maybe mine did not work because i let the attribute name between " and "!!!

Hi , Sorry , Its Typo . Double quote is the way to enclose string.

hey...i could resolve my problem but i have another problem:
i define a string variable in my class (C#)and use it from my page_load... event like this:


Class mypage.... {
String mysession;
protected void page_load {
mysession=session["name"].tostring();
label1.text=mysession;
.
.
.
}

i can just use the variable mysession from page_load. when i run my application label1 shows value of the session.
but i can't use that string variable in another method:

pretected void button_click..... {
label2.text=this.mysession;
...
..
.
}

there is nothing in the string variable and when i run my application i see nothing in the label2 control....
what's it's problem?
