Multi User At One Time
-
Hey Guys need ur advise ! I am currently developing a ASP.net. However i realise an issue is that When Person A log in to See Details of A1 record if Person B log in to see Details of B1. When A refresh it will see Details of B1 instead of A1. It Some how when B log in , the parameter of B overwrited A Any idea to resolve without using Session? Or Session is the only way to handle multi user at one time? if thats' the case all my variable need to be in Session? Please advise. Thanks a million bro

It sounds like you're using static variables, otherwise there's no reason for this to happen. The record you're viewing, is usually stored on the URL, and the current user is stored in the session.

What about Global Variable? It will have the same effect as static? Will Object Oriented be a solution for Multi User at One Time ?

That would obviously be stupid.

Sounds to me like you are very, very lost. You should buy a basic ASP.NET book and read it. You've done things very wrong if you have the problem you're describing. Is this for homework, or for your job ?

OK, so how did you get to have a job that you have no idea how to do ? How about you post some code so we can try to give some specific advice ?

ok for example when i gotten the record id i will store as static string Record_ID = record id so i can use it in the page functions with out declaring or retrieve the record id again like Button_Click1 or any other funtion So if i am not mistaken this will only work on window app am i correct ? so now instead of storing as static i will have to use Session["RecordID"] = record id or once again retieve the Retrieve the ID in every function i need? is that the way to do it?

This is very wrong. 1 - static means it's visible to all users, that is what static does, windows or web 2 - either way, the variable does not persist between page loads anyhow, you need to use viewstate for that. session is to store values between pages, but it's better to put them on the URL if you can.

If you load the value in page load, it will remain the same for that page lifecycle. It just resets every time a page is requested. If your page shows a record, putting the id on the URL makes the most sense.

thanks bro But i need to store quite a number of variable if i put it all in the URL it will be very long So i think Session variable will do right?

You need to store a whole lot of variables for each user ? Why so many ? A query string can be reasonably long. Session is OK, but I try to avoid using it where I can. The thing about a querystring too is, it means the exact page can be bookmarked, as the right page will build itself from the URL.

alright thanks bro i get when u mean. Yup i have a lot of variables some are being pass through to class function or next page. Bro another question is u dun mind. if i declare a variable with in a function let say protected void button1_Click(object sender, EventArgs e) { string RecordID = Request.QueryString("RecordID"); Class class = new Class; //Class I Created DataSet = class.ReturnDS(RecordID); //Function within the Class } if there are mutiple user using is will the RecordID being Mix up again Showing person A Detail of B1 After both person trigger the same function?

No, each users pages get generated using different instances of this class, only statics will get mixed up between users.

Correct me if I am wrong,
staticvariables will stay alive until the application domain unloads and will persist across post-backs.Navaneeth How to use google | Ask smart questions
