Put the object / variable / struct etc into a session variable. This
is an object maintained in the background across all pages. You must
cast it back when retrieving it.
example showing what to to if putting a string into session variable.


putting into:
string s = "hello";
Session["mySession"] = s;


extracting:
string retrieved_s = (string) Session["mySession"];


if a cast doesnt work to convert it back, you may need to try the
Convert.ToString() method or whichever as appropriate for type

i tested your code
this syntax didn't work in asp.net 2 with c# language
i think it works in asp

ofcourse i want to create a page for login to a another page
in first page username and password are checked if were correct go to
second page
but i don't want to a user type the name of second page and view the
page
i want to send a form parameter from first page to second page that
only let to view page if
that variable be true
i hope you understand

dont worry, Im not American either. English.

Ok, so you want to send a boolean accross several pages.

so:

//on login_page.aspx
bool successfulloging = false;

//then write whatever code to test login details and set this boolean
appropriately.
//then put into session variable

Session[s_successfullogin] = successfullogin;



//on the other page you need to take the boolean out of the session
variable

boolean successfullogin = (bool) Session["s_successfullogin"];

if(successfullogin != true)
{
Response.Redirect("login_page.aspx");
}


you can use forms authentication in .net 2.0 also. This is very
simple.

Dont worry bout it, glad to be able to help. Unfortunately, I do not

asp.net 2.0 books. Sorry cant help here.
