In our Application_Start event handler we're performing some actions that intermittently fail due to file locking issues. In this scenario we would like to return the application to an "un-started" state.By this I mean that the user will be shown an error page, and then the next time a user hits the site the Application_Start event will be fired again.
We're using ASP.NET 3.5, WebForms and MVC.
I am trying to register the route collection in .net based on each session. The code I have works fine, you goto website/username and it loads the correct sub pages, but you have to restart the application to goto website/username2 to load those sub pages. But when the application is restarted the second one works, but then not the first one. Is there some way to create a different route collection per session not per application using system.web.routing.
View 3 RepliesIn my MVC application ,I am updating my web.config at runtime through application_start event.So, ideally it should be done only when the application is started.BUT in MY mvc application the application_start event of global.asax is being called multiple
times , even when i have not restarted the application.
Its being repetadly called when i am calling different actions , so the webconfig is repetedly updating & making my application very very slow. what's the reason & how to handle this .
I would like to start a System.Threading.Timer in my application when it launches (maybe deploy is the correct word). I have seen that you can use Application_Start() but this is only fired once the first request comes to the application. I need the timer to start as soon as the application is running so that it can check for work to process even if a user is not interacting with the site. How can I get the application to start the timer once it is up and running?
View 4 RepliesIn our ASP.NET application we perform some initializations upon the Application Start event.When the application is started in visual Studio 2010 with 'Debug->Start new instance' the ASP.NET Development server does not start new, and my Application's Start event is not fired.My workaround is to manually stop the development server - is there a setting to force this automatically?
View 1 RepliesWhat is the right approach when users (authenticated domain admins) should be able to start batch jobs (usually exe files) from an IIS (7.x) aspx (c#) page? This is an intranet site. The batch jobs have to run on the web server as Domain Admins. The website pool is executed by network service or some similar restricted account in AD.
Approaches I can think of (and their disadvantages):
1. Start exe file with System.Diagnostics.Process.Start with another account. This feature is disabled in IIS 7.x, how do I allow it?
2. Create a sheduled task and call scheduled task-api. This unmanaged dll is giving VS compiler warnings because it's unsafe to call from managed code.
3. I suppose there's a better approach, because the previous suggestions doesn't appear safe or robust.
on desktop start has disappeared, getting above issue on double clicking/running any application.have VS2005 installed with sp1 and all other relevant updates as per MS..., i read some forums which states because of VC++ the system files may be currupted....have not installed VC++can anyone guide me the issue here and its solution...
View 3 RepliesI know that ASP.NET MVC has error filter attribute to handle specified error type. However, this feature cannot catch any error that occurs when application start. Therefore, I need to add some code to "Application_Error" method for handling this error like the following code.
public void Application_Error(object sender, EventArgs e)
{// At this point we have information about the error
var ctx = HttpContext.Current;
var exception = ctx.Server.GetLastError();

I have simple 3 tier web application and have mostly CRUDE functionalities. Recently I required to add new console application to the existing solution in which I call data layer methods for retrieving data from DB but I get an exception "The type initializer for threw an exception."When I debugged I found that the exception is thrown at datalayer on first line of class where I get connectionstring from
web.config, the code is public static readonly string CONNECT_STRING =
ConfigurationManager.ConnectionStrings["DbConnectString"].ConnectionString;
Now if I hardcode the connection string value like public static readonly string CONNECT_STRING = "Data Source=XYZ;uid=sa;password=XXX;initial catalog=ABC;"
it works fine.I don't understand what is the issue here as web application works fine with this datalayer.
I'm having a doozy of a problem, and can't find a solution. I have a WFC Web Service installed to a pair of servers, and accessed through a load balancer. I am accessing the service from an ASP.NET client app, also via WCF. The Client is not load balanced.I'm getting an intermittant error:
(Inner Most Exception) System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond x.x.x.x:80(Middle Exception) System.Net.WebException: Unable to connect to the remote server(Outer Exception) System.ServiceModel.EndpointNotFoundException: Could not connect to http://<MYSite>/<MYApp>/<MYService>.svc.TCP error code 10060: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond x.x.x.x:80.
I can reproduce this error with about 20% reliability if I execute the exact same page request on the client from 2 browsers at the same time. When the problem occurs, the successful page request returns in about 5 seconds, and the failed page request returns in about 30 seconds.I'm guessing that there is some additional latency when the load balancer decides to switch my session to another server, and that is making some timeout setting on my client to be exceeded. I need to research this performance characteristic... any thoughtsbut its not my core question.My core question is... Exactly what setting can I tweak to increase the "period of time" the "connected party" is allows to "properly respond".This is the basicHttpBinding configuration I am using on both sides of the communication:
<basicHttpBinding>
<binding name="LongerTimeout"
sendTimeout="03:00:00"
maxReceivedMessageSize="2147483647"
maxBufferPoolSize="2147483647">
<readerQuotas maxArrayLength="2147483647" maxStringContentLength="2147483647"/>
</binding>
</basicHttpBinding>
I've seen some indication that setting the receiveTimeout value on the server may help, but I set this to 1 second in a test environment, and was unable to reproduce the problem, leads me to believe its not worth a production environment change to verify this.
I have a start date and end date parameters.
i need to throw an error when the user enter a ' start date' which is more than 'end date' and an 'end date' which is less than a 'start date' .
the error should be displayed whent he user click the run button
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?
My asp.net application working fine but sometime it suddenly stops and cannot display a page.After restart the PC it works fine again.I am not getting whats the problem. I also restart the IIS then also it not work.
View 6 RepliesI am about to start a new application and am excited about using asp.net mvc and nhibernate. However, the big "problem" is how I handle the user authentication stuff. What are some ways those used to using nhibernate and MVC solve this problem?
My thought is let asp.net do its own thing and I do my own thing database wise. Am curios if I should role my own using the provider model and nhibernate, if I can figure out how. Or is there a way to integrate current code that is in the mvc example into nhibernate?

I would like to create a webpage that will be able to monitor if an application (process) is running.
I would also like the ability to start an application (process) if it is not. Where would I even start?
I am developing my application in asp.net 3.5 and sql server 2005, and I want to record the visitor info into my database, like once the visitor enter my website, I'll insert his browser details to the database. [It's not necessary that visitor login my website].
Now I am confused where to put my code, If I put insert function in every page_load then on every page it will execute and I'll not be able to get the exact number of visitor, visited my website. Shall I go with application_start in Global.asax ??
application start in global.asax file
View 6 RepliesI am writing an asp.net HTTP module which needs to read configuration data once from a local file (say config.xml stored in application root directory) and then based on configuration perform some processing on incoming requests.
Since there is no Application_Start/Application_init hooking available in Asp.NET modules, what would be the best way to handle the scenario. I am trying to avoid reading configuration file each time a request comes. Ideally, I want to read the config file when application starts.
I need to code this in http module only and do not want to use Global.asax
I have a httpmodule that contains a property.
The httpmodule is used in my web application. I want to set the property in the httpmodule when my application starts and not have the overhead of setting it everytime the module is called.
The value for the application is read from my app settings in the web.config.
The httpmodule resides in a seperate dll to the web application.
So I want to inject/set the property from my web application on application start.
How can I make my application installed in my PC to start(ie., to popup for username and password) when I logged in to my PC, so that I can provide my username and password to the application and log in to it,similarly like gtalk that popsup for username and password once logged in to PC?
View 4 RepliesI'm trying to kick off an application within my Programs folder on my web server with this code:

and it's not starting the application but I'm also not getting any errors back from the server. I have made sure that the asp.net user has permissions on the folder, and I can run the application on it's own and it runs fine.
Not using Cassini, but IIS7 to run an ASP.NET app.
The debug behavior is flakey. Sometimes it works, sometimes it doesn't. I was able to step into the application start event in global.asax but sometimes I can't.
Sometimes VS2008 opens the published global.asax so I have two instances of global.asax opened in VS, the source and the published.
I reset the AppDomain and IIS and I can't put my finger on why this is happening.
To add, while it won't go into application start, I have an OnChangeEventHandler event - it does step into the event handler.
I have some scheduled jobs that need to be run in the Application_Start but as far as I know, this method only get triggered after the first request. Is there anyway I can just auto startup the application after I stop and start the connection in IIS or stop/start/restart the site?
