I'm using .Net 2008 and Oracle 10g as my database. The problem I'm getting is after deploying the application in IIS, when multiple users access the same page at a time i'm getting the error. Can't get the output.
Note: Both the users accessing the same page, same menu at a time.
How can I resolve this?
I have to update the users based on input value..
here is my code..
<fieldset>
<legend>StudnetInfo</legend>
here i have two textboxes and two dropdown list boxes.. this is the fiedlset user is going to enter their information..
</fieldset>
on the same page i have couple of other Fieldset with there studentInfo with twotextboxes and two dropdownlistboxes smililarly above Fieldset..this data dynamically generated from database for each users.
so all here my intension is insted of updating each and every Fieldset i made one generic fieldset to update all other Fieldsets information
on the Generic view I have this BeginForm
<% using (Html.BeginForm("Update", "home", FormMethod.Post,
new { @id="studentid"}))
{ %>
my JsonResult is
public JsonResult Update(StudentBE e)
{
try
{
var UStatus = Generic.UpdateStudent(e.student,"","");
return Json(UStatus.ToString());
}
catch (Exception ex)
{
return Json(ex.ToString());
}
finally
{
}
}
using this I can update only one user perfectly but I need to loo update all users based on generic Filedset values?
i am still relatively new to web development and have been encountering some issues when multiple users click a button at the same time.
i was wondering what could be causing this as i have already removed all static variables realiseing that was a mistake and replaced them with viewstates were needed then sessions when moving across pages

View 1 RepliesWe have created an ASP application with MS Access as back end. We have implemented this web application on our server machine and accessed the same from on my local machine.
Our application works fine when only one user accesses it (All insert, update works fine). But when multiple users connect to this application and try to update the database, then application get crashed. As per our knowledge, this is happening because of access database get locked, when one user open it in exclusive mode.
I have a web.config file with <authorization> section. I'm using window authentication.
The problem is that I would like to allow access to the web site to those users who are in multiple roles.
For example:
<authorization>
<allow roles = "Role1 AND Role2"/>
<deny users="*"/>
</authorization>
(Meaning I would like to allow access only to those user who are both in Role1 AND Role2.)
Is this possible to achive this?
If not, what would be the alternatives?
Note: Currently I'm doing the roles assignment in the Global.asax file in the OnAuthenticateRequest event (i'm reading the groups that the current user belong to in the Active Directory).
i have one web service how can i give access to that web service to many user(with secure method). Now i am checking url and only doing for one site. So what should i do.
View 1 RepliesI wanted to know how to prevent more than one user from uploading the report at a time .
This is a Windos based app written in c# . When User A clicks Upload option on one server from the menu to upload the files and at the same time when User B clicks Upload option on different server , User B should be alerted a message saying "User A's uploading is in progress,pls wait" . How to achieve this, with the code..I am thinking this logic should be kept in a stored proc, How do I write that proc?

I have a form which inserts data in DB on Submit button click but the problem is when client click the button multiple times its sends multiple create requests means multiple button click events for the same time of same data, which must not be.
I tried to disable the button when client click the Submit button first time but after this it does not call server click event handler or not fire the server click event once it got disabled.
How to handle this multiple click problem..
I used the following code to disable the button

Is there anything missing in IIS 6.0 that prevents me from (Insert into table) using MS-Access?
Explain: The application works fine under Visual Studio 2008 IDE the insert into table works fine with no error, Also I tested with hosting provider and works fine with no problem. but now I have published the same exact app in a dedicated server windows 2003 with
IIS 6.0 .NET framework 2.0 with latest service pack I gave IIS_WPG write/modify access to the folder where MS-Access database is located and database but at the time of insert an error pop-up. I need to install in the Server or settings in the IIS to recognize my MS-Access db is it some office runtime that I am missing. (BTW I am using OLEDB connection string in my C# )
Using System.Data.OleDb;
I can retrieve data off of it with no problem but when I try to insert is when it fails I thought the problem was Access Rights but I do not think is the case.
"With ASP.NET I've found that request are processed sequentially, one at a time, at least on a server with one CPU. If one request blocks for some reason, maybe on a long database query, then all users must wait
until it completes, for their request to process."
Is this true? Do multi-core processors effect this? Also if you do ahve more than one CPU will it stop processing sequentially automatically or is the default always sequentially?

View 1 RepliesHow do I keep the pages from time out when users are logged in?
View 3 RepliesI have a situation where I am accessing a database multiple times and I'm wondering if it is necessary.
I have a GridView with a template column with a hyperlink to "Get Results" and on the RowDataBound event I have it check the batch number against the database and see if results exist and then if they don't, hide the link.
So when viewing the page if there is 20 rows in the gridview it is effectively doing 20 queries.
I was wondering if it is a better idea to query the database once with all "batches" and load it into a datatable, then on the RowDataBound event query the datatable. The only issue I see with this is there is currently 40,000 batches and grows daily.
I totally have no idea on how to do this. How can I get the time everytime the user use my system. We are using AD account here so we don't have login and log out. All I want is as long as the user browse to my system whether he is working or it or not become away or any, I will record its time and save it in my database then accumulate all the time he spent in my system for admin reporting.
View 5 Repliesi have to implement a requirement that's kind of weird for web apps (intranet web app).
after an user login to the app, the user may press Ctrl + N to open the current page in a new window. this sounds perfectly normal except the business requirement is to prevent users from doing this. users must logoff before they can access to the app again with a different browser window/tab.
So I have a text box and a button, once the user types something in the text box, and then click button, I posted the typed text into a div control on the same page.Now my problem is that, the text box appears to have the typed text, how to resolve this type of issue? I don't want to redirect users all the time after they click the button.
View 4 RepliesI'm planning to make a page that has about 10 different pages for varying use, for example, stats, data entry, reports, logistics, audit, sales, promo, etc etc. I'm anticipating there will be many combinations as to what pages a user may have access to, for each page, a user ought to be authorized to either enter new data, edit data, print and/or just view.
My questions are :
1. can membership & roles be used, once user is logged in, to display links to all the areas of the web app he is allowed access to?
[code]....
2. besides having access to a particular page, a user should, as mentioned before, be authorized to either enter new, edit, print and/or just view data.
3. Is there a preferred/better method to handle this besides using membership & roles?
I have an ASP.Net 4.0 web application which very frequently loads data from the database and does heavy calculations on it. I want to cache this loaded and prepared data in a central cache that can be accessed by every user and computer who uses the application.
Simple use-case:
User 1 accesses webpage, cache is empty, data is loaded/calculated, data is cached
User 2 accesses webpage, cache contains data, data loaded from cache
User 3 accesses webpage, cache contains data, data loaded from cache
User 1 reloads webpage, cache contains data, data loaded from cache
Cache expires
User 3 refreshes webpage, cache is empty, data is loaded/calculated, data is cached
I know that ASP.Net has a built-in cache mechanism. What I don't know is whether it can be shared between different users accessing the site on different computer at the same time. I would also like to know how the system behaves in a web farm environment.
in development time i can managment roles and users by clicking from main menu website -- > ASP.Net Configuration but how to do that after deploy ??
