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.
Is there a way how I can check programmatically which user is used when my application accesses resources?
I have a production system which only our admin can access. Sometimes it is not clear what part of the system is wrong: Lets say when logging is not working. It is always possible that the web.config is wrong, but sometimes the directory is not accessible. It would make my life easier if I could be sure, that the user is used, that I expected.
I 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)
If 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?
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.
View 1 RepliesI 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:
Resource name '<name>.Resources.resources' cannot be used more than once.

View 5 Repliesi have agridView that i fill its contents in thr runtime and i need to make a check box infront of each row.
i tried to make acheckbox field but it didn't appear in the grid.
I have been searching the net for four hours now and am coming up empty.What I am trying to do is to check and see if a value exsits in a column of a gridview and if it does not then do something. Basically I have a gridview that gets populated when a value in a dropdownlist is selected. This works fine. I get the information for the gridview by binding it to a SQLDataSource that returns two columns in a table from my SQL Server. The gridview only has two columns and one row as I am checking it from the dropdownlist. The second boundfield column is called Manufacturing Fee and it is a Money Type in SQL Server. I want to check if there is any value or if it ISNULL. If it is NULL or empty or less than 1 (any if these will work) then I am going to hide a button on the page so the user cannot do anything until this value gets assigned. (I know how to create this logic).I do not know how to get a value from the GridView as I am not selecting anything so I cannot use the SelectedIndexChange event or ONClick event.

We usually catch unhandled exceptions in Global.asax, and then we redirect to a nice friendly error page. This is fine for the Live environment, but in our development environment we would like to check if CustomErrors are Off, and if so, just throw the ugly error.
Is there an easy way to check if CustomErrors are Off through code?

I'm noticing VERY slow load times, on the order of a couple minutes to like 5-6 minutes to load a page. I really don't think this is working right.

Now a days my company started using some third party tool in our web application they aslo instructed to our team to make the dll for every web application
The steps for creating the dll for web application?
1)to use a web application to make a website why does no code behind file appear in code behind?2)when i deploy to a website I need to place the web app .dll in a bin folder on root.This works but to make any changes i need to compile and upload the aspx file as well as the new dll?

View 1 RepliesI've written a singleton class that exposes the web.config properties in a nice get property kind of way.
I want a Load method to parse the data in the config and set the public properties, and I want to throw exceptions (so they are logged in the EventLog) when a configuration key is missing or can't be parsed.
I tried placing the Load() code in Application_Start of the global.asax but then remembered this will only be run once, or until the application restarts.
Where is the best place to put code that you need to run 'everytime' your site is started/run by the user? I basically want the website to stop functioning if certain config properties cannot be loaded.
I am working on an ASP.NET web application, we are a small team (4 students) and we do not have access to a dedicated server to host the database instance. So for this web application we decided just to put the database file in the App_Data folder.
The problem is that our project is source controled on TFS, so every time you open the solution and try to launch the web application, we get an expcetion saying that database is read-only. That is logical because the databse file is not automatically checked-out.
As the title says, I wan't to run some code when the application starts. I have a vague idea that there is probably an event in the application life cycle but I am a bit unsure and could do with pointing in the right direction. So how do I make code run when the application starts?
View 5 RepliesSo, after all and after all these projects that have been done. What is the best way and I should consider as standard in the furute to start any further ASP.NET Projects that are database driven.
I have done many using
1. Store procedures and classes
2. One class to handle all the add,delete,update ...etc functions
3. ADO.NET
4. Using sql statements directly on the code (I know not recommended, it was my first project) :))
..and so on
What method you recommend in the future that will save me code and errors and optimize my application speed as well.
