SQL Server :: Deadlocked Transaction On Lock Resources

Sep 24, 2010

I develop an application using LINQ to SQL. Recently I deploy the application on server and starts performance testing using WAPT for 100 users. Unfortunately, 90 requests are failed while placing an order and only 10 are passed. I analyse and found that for every failed request I got an error "System Exception: Transaction (Process Id 68) was Deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction."

How To Lock Down & Secure Files Stored On Server In .NET

Apr 23, 2010

How do I go about securing files that are stored on the server? We have an ASP.NET app which generates PDFs. These are not stored in the wwwroot folder but in another folder i.e. C:inetpubdata. This provides more security but maybe not enough. The ASP.NET/IIS process will need write access to this folder so it generate the PDFs there.

Once the pdf is generated, it can be viewed using an ASP.NET form called viewpdf.aspx with the file to be viewed add to the query string like so viewpdf.aspx?FILE=mynewfile.pdf. This is loaded from a gridview.

The full path to C:inetpubdata is resolved and loaded in the Page_load event of the viewer page. Now I'm wondering how to secure this. Anybody could just view the file. Not by entering in the URL, as it won't been seen by IIS (its not in wwwroot), but could change the querystring in the viewpdf page.

How do I stop anybody hacking this?

ADO.NET :: Performance Advantage To Using EF?

Mar 14, 2011

I'm now getting into EF and from what I'm seeing so far, I wouldn't have to worry about writing stored procedures any more. Looks like EF takes care of all of that -- including INSERT's that store data in multiple tables. One of the things they taught us when learning stored procedures was that they're compiled which has performance benefits. How does EF 4 fare against using stored procedures?

Advantage Of Themes Versus CSS?

Jan 24, 2010

Since Themes in ASP.NET are used to style elements of your site, I was just wondering why would you use Themes rather than CSS, or is it common practice to use both? If so, when would you opt for one versus the other and why?

Just seems to me like Themes are kind of unnecessary, so I am just looking on clarification if there really is a good reason to use them, or it's just a part of the framework as an alternative(unnecessary) step to styling your site.

MVC :: What Is The Biggest Advantage In Comparison With Webform

Jul 25, 2010

I hate webform that no matter what action is done with a client side page(such as clicking a dropdownlist to only see the Items), it cause a postback&re-rendering of the whole page and all of the page events is raised( page_init,page_load....complete....).

We know that the server side .cs page shoudnt have to go through all the events and many methods(such as "IsPostback",viewstate), in fact,it just have to do only one thing:get data from DB for the dropdownlist and show it to us, other part of the page just doesnt have to change.

We may achieve this effect using Ajax, but the key is I dont wanna raise too many useless event .

seems MVC can handle such a problem, one action of browser side is replied by exactly one method,and time isnot waste by raise event...

Is this the biggest advantage of MVC?

Typesafe Coding And The Advantage Of Storing The Object In The Session?

Nov 24, 2010

When i started developing web applications i stored the authentication details of the user in two session variables

Session["UserName"]="username";
Session["Password"]="paswword-123";

But someone proposed me an idea to create a class which holds the UserName and Password properties and on succesful authentication i have been asked to create an instance of the class and set the UserName and Password properties and store that instance in the session.

I have been told that the session object is TypeSafe. Can someone explain what is typesafe coding and the advantage of storing the object in the session.

SQL Server :: Error "Transaction (Process ID) Was Deadlocked On Lock Resources With Another Process And Has Been Chosen"

Jul 23, 2010

I have a stored procedure which fetches data after joining 8-9 tables and inserts that into a temp table. It was running fine till now, but now when the amount of data fetched have exceeded 20000, the SP is breaking. I have debugged the sp and found that this main query is failing after returning arround 15000-16000 records.

The error message says Transaction (Process ID) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction. I know what is deadlock, but when i checked with SP_LOCK stored proc i only found that my process is running on database only. So how is this getting deadlocked when there are no other processes running simultaneously on server.
