if there's any documentation/resources the describes the complete process flow of an ASP.Net application? Looking for something that describes IIS handing off the HttpRequest and the usage of the PageParserFilters and such.

i ..need complete flow of application hosting procedure and how to configure IIS
View 2 RepliesI 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.
I have an invoke function that I call. It On the client side it reads a file and then sends the line to the server side function here and waits for a return. Here is the server side code:
[Code]....
What I find is that I will keep getting these error message as posted in the subject... It will work for some but others I get this message. Thoughts on how to avoid that, or is that just something I'll need to work around with timing?
I need to show the busy indicator when some action is taken and i should show the time until the process gets completed.
I referred [URL] ..... link and its great.
But i found the code System.Threading.Thread.Sleep(5000);.
I should not add the fake delay as it is my process is long process to run....
While updating table Un handled exception was raised (asp.net with c# and SQLServer 2005)
Error Message: "Transaction (Process ID 91) was deadlocked on lock | communication buffer resources with another process and has been chosen as the deadlock victim. Rerun the transaction."
When I hit the run button (in my Default.aspx), a process starts (this process contacts a webservice to get some files, etc). How do I: Ensure that only a single process is running at a time (i.e. if I refresh the browser, I don't want to start the process a second time)Track progress - there are 4 points of the process (at 25%, 50%, 75%, 100%) that I want to track, and when each part completes, I want to update the progress bar. I have a status object for the running process, but the question is how to update the progress bar automatically? Do I need to use threads to achieve the above two?

MSDN "ASP.NET Delegation" article tells:
1) "When you configure to use a particular account as the process identity, ASP.NET attempts to delegate that account. If it is a local account that is identical (including password) to a local account on a remote machine, delegation is possible. If such an account does not exist on the remote machine, to the network it appears as the Windows anonymous account (NT AUTHORITYANONYMOUS LOGON). In addition, delegation is also possible if the account is a domain account that has access to the remote machine, in which case it uses the domain network identity of that account."
The same frequently repeated story as in case of manually/interactively accessing remote computer (server resource) in workgroup - it is necessary to create local account with the same username, the same password. But why?
If a workgroup Windows client process cannot access resources on server machine without having duplicate of such (local) account on target machine already pre-created,does it mean that client (process, machine, or user) can access server resources only by/after having logged (opening logon session) into server machine? Or, how to understand that such access is impossible without having corresponding duplicate local account on server machine?
The same MSDN "ASP.NET Delegation" article tells:
"NetworkService account. It behaves the same as the System account. This account possesses the network credentials associated with the machine account (domainnamemachinename) in the domain of which it is a member"
Does not any Windows have accounts ((NT AUTHORITYNETWORK SERVICE)? as well as many other common pre-built accounts? Why are they installed (before any joining to domain) but cannot be used for remote network access and client identification ? And what is identity used when the process from workgroup Windows under identity ((NT AUTHORITYNETWORK SERVICE) accesses a remote server?

I want to unit test my asp.net web application using NUnit.
For this I have downloaded and installed NUnit from internet.
But since I am new to this tool , I am looking for documentation about this tool.
How can I use this tool for testing web applications? give me links to documentation?
Also is it possible to integrate NUnit with visual studio, if yes, how?
We have a website on IIS7 using ASP.NET Routing that seems as though it might be running out of resources.It just hangs after a few days, there is no error message or apparent crash.
We are making sure every .Open command is matched by a .Close command on the database connection.
We are doing the same with file Open/Close but there are very few of those.
These questions were asked me in a technical interview:If we deploy an application on multiple server (like database server, web server) then, each request should be redirected to proper server, then how you will handle it in your code?How security pinholes will be handled in an application?What things should be considered while writing a web application?How will you do load/performance testing of web application? hich framework you will use for it?How will you implement a cache for results which require a DB access?Please let me know how to write an web application considering all these points. I am not so much aware of architechural design of web application.
View 2 RepliesI am planning to convert desktop application which has to deal with lots of client resources like printer, Id scanner(driver license,passport & business card etc.), webcam etc.Now accessing client resources like files, scanners and webcam everything has to be done through client side scripting which is really pain. Due to nature of this product, I have to create image on client PC and extract information from it. (This is also pain in Vista and Windows 7 due to security permissions and all that stuff).
My ideal design would be making managed dll which takes care of dealing with images, printers, webcam (I have to apply pan, tilt and zoom), id-scanners. This is kind of component. And GUI would be web based Asp.net which simply calls the functions of managed dll. If the end-user is opening application on new computer, then it will ask just like flash or silverlight that you have to install component locally for the first time.Points which I worry: 1. If it logically correct or sounds stupid? 2. How to install managed dll at end-user's PC (C:/program files) and use it from asp.net code behind page.
My application is intranet application.so avoid stupid assumptions about privacy and ohhooo you want to access files from my PC and all those stuff. (end-user would never mind in giving credit card to restaurnt waiter who could do anything with it behind counter but allowing web application to access file which is created by application is privacy issue)

View 3 RepliesIf a user clicked on a button, which runs a one minute process that MUST stay connected to the file (through the use of FileStream) for writing purpose, and he/she accidentally closed the browser. Currently, when that happens, if the user clicks on the button again, it will return an exception saying that the file is still being used. The part where I write to the file, the code for that is in a class library, which has a destructor (or finalizer, whichever), which calls a Dispose() method. It would usually take about 20 seconds before the file is free again to be used, but is there a way to make it quicker?
I'm thinking the way I'm designing my web app is not the conventional way. How do most people avoid this situation (ie. accidentally closing browser) where a file/resources are not freed up? Do they write into a SQL server instead of a flat file?
I am logged in as the administrator when I installed an application named pdflatex.exe on my server. This application works as a converter from LaTeX input file to Pdf file. I host an Asp.net MVC 3 application running under an Application Pool Identity with Load User Profile = True. The Asp.net MVC 3 code contains a code that executes pdflatex.exe using System.Diagnostic.Process instance as follows:
Process p = new Process();
p.EnableRaisingEvents = true;
p.Exited += new EventHandler(p_Exited);
p.StartInfo.Arguments = "-interaction=nonstopmode " + inputpath;
p.StartInfo.WorkingDirectory = @"c:mydomain.comworking";
p.StartInfo.UseShellExecute = false;
p.StartInfo.FileName = "pdflatex.exe";
p.Start();
p.WaitForExit();
From the scenario above, the web application runs under a restricted acount but it executes an external application under a default account that I don't know. Can an application running under a less privileged account start a process executing another application under an administrative account?
I have recently upgraded to VS 2010 and converted my web site into a web application. Now, when I attempt to build, I receive the error:

There is no page name or anything, and I have completely exhausted all that Google has to offer.
I'm building an ASP.NET MVC site where I want to use OpenSTV to conduct polls. To run results through OpenSTV, I'd have to run the executable. Is that allowed from a medium-trust ASP.NET application?

View 1 RepliesRunning an ASP.NET application in its own app pool on Windows Server 08 / IIS 7.
Server keeps hitting 97% memory usage and sticking there, trying to work out if that is our application's fault.
My main question is, does all of the memory used by an application get displayed as the working set for the w3wp.exe process associated to it? Our application (according to IIS7 and the worker process in task manager) is using less then 350mb. I want to know if it is possible for our application to be using 5GB of memory but only showing 350mb for the process?
What is the difference between IIS Worker process, Application pool and application domain? Do we have more than one application domains in one application pool?Does one application domain means one virtual directory?
If we have 2 virtual directories pointing to same physical folder. Will they share the same memory or different when there instances are opened in the browser? Will they be in 2 different application domains?
I am trying to config my application to use out-of-process sessionState.
<sessionstate mode="stateserver" cookieless="false" timeout="20" sqlconnectionstring="data source=127.0.0.1;user id=<user id>;password=<password>" server="127.0.0.1" port="42424" />In my web.config I get errors for the server and port attributes, telling me that server attribute is not allowed and port attribute is not allowed.
I need to use [System.Diagnostics.Process ] class in my web project to execute a *.exe file. I can also use the [CreateNoWindow ] property to make it invisible while it does it job behind the scenes. However, webhosting companies do not allow .exe files to be executed on the web. I read some where that if I place the same code (which invokes the .exe file) in a separate class library project and use the respective [dll] in my web application, it will work.
