The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

c#.net cookies & session varilabes

Zone: .NET

Tags: session, cookies

I normaly have always used session variables just becuase they are esier for me to set and retrive and never had more then two or three.....well session variables have become very unrealiable froceing me to use cookies. I have no idea what the heck the proplem is here. It keeps giveing my object not set error but i'm sure i have set the cookies.

Default home page:

if (UserTB.Rows.Count > 0)
 {
 HttpCookie cook = new HttpCookie("UserInfo");
 cook.Values.Add("UserRole",UserTB.Rows[0]["Role"].ToString());
 cook.Values.Add("LOBID", UserTB.Rows[0]["LOBID"].ToString());
 cook.Values.Add("UserID", UserTB.Rows[0]["RecID"].ToString());
//Response.Cookies.Add(cook);
 Response.AppendCookie(cook);
// HttpCookie = new HttpCookie("LOBID", UserTB.Rows[0]["LOBID"].ToString());
// HttpCookie = new HttpCookie("UserID", UserTB.Rows[0]["RecID"].ToString());

 }

I think click leaveing the default page and going to another where i call the cookie

Response.Write(Request.Cookies["UserRole"].Values["LOBID"].ToString() + " ");
Response.Write(Request.Cookies["UserRole"].Values["UserID"].ToString() + " ");
Response.Write(Request.Cookies["UserRole"].Values["UserRole"].ToString() + " ");

why...won't...this...work...please help

sorry guys
i changed
Response.Write(Request.Cookies["UserRole"].Values["LOBID"].ToString() + " ");
Response.Write(Request.Cookies["UserRole"].Values["UserID"].ToString() + " ");
Response.Write(Request.Cookies["UserRole"].Values["UserRole"].ToString() + " ");

Too:
Response.Write(Request.Cookies["UserInfo"].Values["LOBID"].ToString() + " ");
Response.Write(Request.Cookies["UserInfo"].Values["UserID"].ToString() + " ");
Response.Write(Request.Cookies["UserInfo"].Values["UserRole"].ToString() + " ");

I think i need to take a break haha
ok so code again is this and its give object not set

Default home page:

if (UserTB.Rows.Count > 0)
{
HttpCookie cook = new HttpCookie("UserInfo");
cook.Values.Add("UserRole",UserTB.Rows[0]["Role"].ToString());
cook.Values.Add("LOBID", UserTB.Rows[0]["LOBID"].ToString());
cook.Values.Add("UserID", UserTB.Rows[0]["RecID"].ToString());
//Response.Cookies.Add(cook);
Response.AppendCookie(cook);
// HttpCookie = new HttpCookie("LOBID", UserTB.Rows[0]["LOBID"].ToString());
// HttpCookie = new HttpCookie("UserID", UserTB.Rows[0]["RecID"].ToString());

}

I then click leaveing the default page and going to another where i call the cookie

Response.Write(Request.Cookies["UserInfo"].Values["LOBID"].ToString() + " ");
Response.Write(Request.Cookies["UserInfo"].Values["UserID"].ToString() + " ");
Response.Write(Request.Cookies["UserInfo"].Values["UserRole"].ToString() + " ");

Try to define when cookie expires:
cook.Expires = DateTime.Now + TimeSpan.FromDays(1);

If you want to remove cookie set expires time in past:
cook.Expires = DateTime.Now - TimeSpan.FromDays(1);

From MSDN:
AppendCookie: This member supports the .NET Framework infrastructure and is not intended to be used directly from your code

Try to use:
Response.Cookies.Add(cook);

So cookie is sent. Where in your code you want to obtain cookie ?
You need to set breakpoints and see which object is null.
Response, request or cookie ?

try this:
if (Response == null)
{
System.Diagnostic.Trace.WriteLine("Response is null");
return;
}

if (Request == null)
{
System.Diagnostic.Trace.WriteLine("Request is null");
return;
}

HttpCookie cook = Request.Cookies["UserInfo"];
if (cook == null)
{
System.Diagnostic.Trace.WriteLine("Cookie is is null");
return;
}

Response.Write(Request.Cookies["UserInfo"].Values["LOBID"].ToString() + " ");
Response.Write(Request.Cookies["UserInfo"].Values["UserID"].ToString() + " ");
Response.Write(Request.Cookies["UserInfo"].Values["UserRole"].ToString() + " ");

Or you can try to obtain cookie like this:
HttpCookie cook;
if (HttpContext.Current.Request != null)
{
cook = HttpContext.Current.Request.Cookies["UserInfo"];
}

Accepted Solution

cookie valued are string so you don't need:

cook.Values["UserRole"].ToString()

try this:

HttpCookie cook;
cook = HttpContext.Current.Request.Cookies["UserInfo"];

string userRole = cook.Values["UserRole"];

Response.Write(userRole + " ");

Where you get error ?
If error ocurre in line with "response" then Response object is null, and with cookie is everythig ok.

01.18.2005 at 02:59PM PST, ID: 13077871

On which page and in which event you set cookie ?
Try to set cookie on the first page in OnLoad event.
This way cookie will be set in first response to user. Then you will must have them on the second page.

01.18.2005 at 06:10PM PST, ID: 13079047

j_tipps:

the default page sets the cookie then i click and hyperlink to go to addvender. On the addvender page i have a button that raises the event to check the cookie.
Thanks for all the help. I don't konw what the the deal is. I'm at home now and when I VPN and go the site it works fine. I even changed the code back to
Response.Write(Request.Cookies["UserInfo"].Values["UserRole"].ToString() + " ");
and it works....no idea man. I'll go ahead and give you the points since you helped me out anyways.

Do you use VS.net to dev. in? and if so does it ever put funky charters in your html like '?' or anything. mine does and its freakn anouing.
