I've got an application that needs to do some work on startup (before the first request is in). I've added the initialization code in the global.asax file (Application_start method) but this code doesn't seem to be hit after an iis reset is performed.Is there an event which is triggered in an asp.net application when an iis reset has occurred?

I recently developed a simple application for displaying a list of files to some users based on access levels and allowing them to download them etc.
This application was developed to be hosted inside a large corporation with heavy security policies and is fairly mission critical.. The application is very basic,
it checks the users NTID (using windows authentication) compares that to a table in SQL then pulls up a list of all the files on which this user has access Thats pretty much it.. There are also a couple of forms for adding a user and editing a user and uploading a file.
We have a problem often where the application is pretty much unresponsive. This can be remedied by opening command prompt and running 'iisreset' I should also note when originally deploying the application we changed some settings on the server to allow connections to stay open a while longer to allow bigger file uploads.. Could this be locking the application up? I am unabble to restart the server until the weekend. The server is a windows 2003 box running IIS6.0 and .NET 2.0
simple explanation like:- four blocks all connected to one server hosting a website using iis 5 c# i want if user from block a accesses the home page the page says block A user how are you, same goes for all blocks so how to identify from where the request is coming from in this simple scenerio
View 1 RepliesI have a server application that runs in a hosted environment but creates print jobs in the client's local network (behind NAT; the mechanics of this is not relevant).
In order to send the print job to the printer that is attached to the workstation, I need to identify the workstation. The users move around between workstations, so I can't permanently associate a user with a workstation/printer. The trivial solution is to require the user to identify the machine he is logging in from, for instance by selecting from a list, but that's an inconvenience and subject to user error.
Options I have eliminated:
Host header variables (nothing identifiable is sent) Cookies, in support of a user selection. This somewhat addresses the potential for user error, but not really. HTML5 DOM Storage - is not supported by the client's browser
Edit: I do have the option of puttnig this particular function (create a print job) into a thick client app. The app can then of course be configured and the problem goes away. But the user experience will suffer from having to switch between the browser and a Windows app.
How can i identify just from the HttpContext Object that the HttpRequest coming to my application is from a cookieless application or cookieless browser?
View 2 RepliesI have a web application project on my dev PC running WinXP and hence IIS 5.1. The changes I'm making to this site seem to "take effect" only after I do IISRESET. That is, I make a source change, Rebuild the project and then Start without Debugging (or with debugging). The newly changed code is not "visible" or in effect unless I intervene with an IISRESET.
BTW, the "web" tab on the Properties display for the web app project is configured to use the Local IIS web server at project Url: http://localhost/myVirtualDirectory
...
but I've noticed the same issue when using the VStudio Dev Server (i.e. I have to stop it by visiting the taskbar tray area in order to see my source changes take effect).
Is this something I can change?
EDIT UPDATE:
Just wanting to clear this up if possible. Two answers diverge below; not sure how to move forward. One states this is to be expected (weakness of IIS 5.1 which in turn is the best WinXP can provide). Another states this is not expected behavior (and I tend to agree since this is the first I've encounted this on the same old WinXP dev platform I've had a long time). I suspect it may be something "deep inside" the Visual Studio 2008 web app which was upgraded to this new IDE from VStudio 2002 (ASP.NET 1.1). I've tried to add comment/questions down each answer path.
some reason that I can't figure out, the iisreset command prohibits the webserver extension ASP.NET 2.0.50727 and this prevents the site being accessible.I would have to manually allow the webserver extension so that the site becomes accessible.This happens only on one of the load balanced servers.The rest work fine without any issues.
View 3 RepliesI am starting a new website based on an existing one that I already have up and working. I copied the old website files into a new folder but it will not run.

The problem is that there is no a special exception class for 404 errors, I get regular System.Web.HttpException with Message = "File does not exist."
Should I just use exception's message for it or is there a better way?

View 1 RepliesDoes anybody know how to properly identify CMYK images in ASP.NET using C#? When I check the Flags attribute of a Bitmap instance, I get incorrect results.
I have created three images to test this: cmyk.jpg, rgb.jpg and gray.jpg. These are respectively CMYK, RGB and Grayscale images.
This is my test code:
[Code]....
This produces the following output:
I have checked the actual images and cmyk.jpg really is a CMYK image.
Apparently, this is a "known issue". Alex Gil had the same problem in WPF (see this question: How to identify CMYK images using C#) and he managed to solve it by using a BitmapDecoder class to load the images. I'm a bit uncomfortable using that solution in ASP.NET because it requires me to add references to WindowsBase.dll and PresentationCore.dll and I'm not sure I want those in a web project.
Does anyone know of any other pure .NET solutions to check if an image is in the CMYK format that I can safely use in ASP.NET?

I have an ASP.Net app with a lot of pages in it.My problem is to uniquely identify every page in my app. now the app might have pages with just the page name eg: home.aspx and can have pages with query strings eg:testPage.aspx?q1=1&q2=2.what i have been thinking is since every URL in my app is unique I could use the page name + all query string params concatenated(key and value) to identify the page uniquely.eg:home.asp home testPage.aspx?q1=1&q2=2 -> testpageq11q22.Is this the correct way to go or is there a better way to do it.The reason I want to do this is I need to add at run time some meta data information from a database for each of the pages.The PageID then becomes my unique ID which I can then map all my meta data info in the db to.
[code]...
would potentially point to the same page (where the optional param gives me some kind of meta information thats is not being used to generate the content on the page)
I have a masterpage that contains a user control. The usercontrol uses callbacks for various operations.

I know how to identify the current user during a specific browsing session and can thus control the data, etc, made visible to that individual user. I also know how to find out how many users logged in within the recent past, using:
Membership.GetNumberOfUsersOnline()
.... which I believe calculates the number of users who have logged in within the past 15 minutes. However, I would like to know if there is any way to identify all the users who are logged in at a point in time. Is this possible?
I have a UserControl (UC) which is in an UpdatePanel. When the UC is loaded, I run a recursive method to set tooltip for all Button, LinkButton, and DropDownList in this UC. The problem is sometimes I only update 1 control in the UC such as a DropDownList, but I have to call the recursive method on all controls of the UC. I was wondering whether there is any way to identify which controls is updated in the UpdatePanel so that I can update correctly these controls.

View 1 RepliesI have a stored procedure which is composed of three unions of three different views.
After the views are Unioned together, they are placed into a temporary table.
I need to somehow keep track of the data which comes from the second view, "View2".
Specifically I will later need to compare all Ages of people from the second view.
How can I do this? Here is an example of my unioned views

Select Name,Age,Gender from View3
I would like to identify if an email address comes from a public provider or is from an established business. I consider public email addresses to be things such as:
Open email service providers, such as gmail, hotmail and yahoo. Anonymization services, such as mailinator or dispostable.
I'm aware that there is no foolproof way to do this, and obviously any list based solution would require constant updates.
Is there a public listing or .NET library that can do this for me?
