MVC :: Firing Startup Tasks?
Jun 21, 2010
I used Castle Windsor before and had this routine that fired the certain method of all classes that implement a certain interface.If I recall correctly, the interface was IBootStrapTask and only had an excecute method. Then, for instance, I'd place all my route registrations in one of these, and know it get fired on application startup.Have to admit I did not understand the code to well, so I'm even more unsure how can I do this. I'm using structure map now. (still knowing very little about it)

I have just started to look at the new "System.Threading.Tasks" goodness in .Net 4.0, and would like to know if there is any build in support for limiting the number of concurrent tasks that run at once, or if this should be manually handled.
E.G: If I need to call a calculation method 100 times, is there a way to set up 100 Tasks, but have only 5 execute simultaneously? The answer may just be to create 5 tasks, call Task.WaitAny, and create a new Task as each previous one finishes. I just want to make sure I am not missing a trick if there is a better way to do this.

Are all loaded on web app startup or only when they’re invoked (i.e., when their code is used)?

I am in a partnership with someone. We are currently planning a system that can either use ASP.NET MVC or PHP With //Insert your framework here//. At this stage I can't say to much. Now the thing is I have a bit of experience with C# and MVC. I understand the concepts and actually wrote a fully functional blog with it. Now the other side of me wants to take PHP for a test drive. Will I waste my time? How good will ASP.NET MVC scale against PHP? I have to say that I love visual studio and the integration of MVC tools like quickly adding a view and a controller... Everything fits nicely. But the learning curve was quite steep and still is. I haven't really touched AJAX and Jquery yet but how easy is it to use it with ASP.NET MVC? I already googled and researched this but I want opinions of those who have been working with these technologies.

I have a site in which I have defined my Start up page, say Sample.aspx. After deployment in server named "Siteserver, Now whenever I open link [URL]. Now, my question is, if I have more than one page like Sample1.aspx and Sample2.aspx and I want to open [URL] directly, how can I do this. It is redirecting again to Sample.aspx. How can I achieve this.

I know that when a .NET web application first starts, it will be slow on first access. For that reason, I created a 'keep alive' page in the application that is requested every 8 minutes or so by a scheduled process. I hoped that that would be sufficient to prevent the application from 'unloading' and thus suffer from this initial long startup time again and again.
I can see in my logs that the 'keep alive' page is indeed triggered every 8 minutes, 24 hours a day. But when I actively start working in the application after some time, eg. the following day, I still have to wait a while for it to start up. Once the first page is loaded, all is fine again.

I have around 10 "Excute SQL Task" events in sequence. Each Task uses the same two date parameters, which are declared at the top of each script. Is there a way to set these two at the start of the process instead of within each sql script?

we have this problem but can't find a solution. We have an application that references something like 24 dlls. When you invoke the application the very first time (after the application is for any reason reset) it takes 25-40 seconds to start loading contents.
This is what we tried:
1. precompile and publish everything in release mode
2. removing pdbs from bin folder
3. put strong named assemblies into GAC
4. set application to debug = false
consider that the whole bin folder is composed by 24 dlls for a total size of 28MB. Just 4 of these dlls are strong named and they are more and less 25MB. Nothing seems changed. What happens EXACTLY when the application is started is something I couldn't find in any book nor forum/blog/post... What can we monitor more to find where the problem is?

I went to the Code Plex site and down load the latest toolkit. Then followed the instructions on how to set up the toolkit to the letter. When I first loaded the toolkit everything worked. But now every time I start up my computer and start VS all the AJAX controls I have on any page has the green squiggly line underneath it and the error says:Element <AJAX Control Name> is not a known element. This can occur if there is a compilation error in the web site, or the webconfig file is missing.The only thing I can do is delete the Ajax Toolkit tab then add the tab again and then "Choose Items..." and load the Ajax controls again. Then I have to add an AJAX control from the toolkit to any webpage. Once that is done all the green squiggly lines go away and I can continue.This is becoming an incredible pain.

When I start debugging my application using vs2010 before the default.aspx page is rendered the application_error event is fired in global.asax.
There is nothing happening in the page_load of the default.aspx screen.However, if I set a break point on the default.aspx page_load event and the application_error event here are the sequence of events: The page_load event of default.aspx is fired, there is no code to execute there so I hit F5 to continue. The application_error event is then fired.Here are some of the details from Server.GetLastError();
exception message is "File does not exist."
stack trace:
at System.Web.StaticFileHandler.GetFileInfo(String virtualPathWithPathInfo, String physicalPath, HttpResponse response)
at System.Web.StaticFileHandler.ProcessRequestInternal(HttpContext context, String overrideVirtualPath)
[code]...
I have absolutely no idea why this event is fired. Do all of the events in the Global.asax get fired on startup?There is nothing happening on the page_load so how can an error be thrown?

My application is running in a shared hosting environment. I do have a dedicated App Pool for my app. I've been doing some testing with 1st visits and precompile performance and have been tracking when my application starts up and shuts down.
In my Global.asax I have some logging code in Application_Start and Application_End. I can see from my logs generally when the application is idle and shuts down, then someone visits and it starts back up.
But, I also see cases where a shutdown is logged and then followed by another shutdown about 13 minutes later; without a startup in the middle.
I also see instances where there are two Startups in a row. I'm guessing these might be a recycle, but why wouldn't there be a shutdown log entry?
What I'd really like to know if there is a better way to track when my application starts, when it shuts down and if it is shutdown due to an idle pool, or from a recycle. I don't have access to the Windows Event Log so I need to do this from my app if possible.

I'm sure I'm missing something extremely obvious here, but at this point I can't see it so I need the help.Anyway, I've got a repeater inside of an UpdatePanel. As of right now, I've stripped it down to this, just to try and isolate the problem:
[Code]....
Whether I add the handler during itemdatabound or I add the handler within the repeater itself, it doesn't seem to matter...the event itself doesn't fire. The AutoPostback itself seems to fire, but the event itself doesn't.

I am a beginner of C# programming. I have read a few books about C#.net. But I cannot find some exercises in the books. Someone told me to build up a blog to practice my coding.
But it is a huge task for a beginner. I just want some tasks to have a step by step learning process.

I want to be able to create a style sheet at session startup (based on a large number of variables... this sheet must be created on the fly and can not be hard coded). At the moment i can set up styles and apply them to controls using the VS designer (html behind of a page). But i need to be able to create these styles at runtime because they will differ for each session. The names of the styles may not differ, but the elements inside the style will be changing.
I figured that one thing i could do is create a css file using System.IO to create the file and then use that to apply (but even then, im not sure how i go from creating the file to including it in the project at runtime), but is there an easier way?

In my ASP.NET website, I am having a function which has to be automatically performed once every 2-3 mins on its own, i.e. without user intervention. This function contains database access.
Can I use threading to perform this process in background?
If Yes, How can I use that?
Edit
Also I am not looking for a solution which includes windows service because I am using shared hosting. So I dont have all the rights to access the host computer.

I am little bit confuse with Asp.net MVC Area.
When we talk about WebForms we say, for Administrative tasks, you must have an Admin folder to separate the admin task.
In MVC how i will treat my Admin tasks?
I will go for Admin Area or Admin Controllers,
Because if i will write controller for Admin tasks, each and every task will be written in one controller (AdminController) or if i will write Area -> Controller, means i will need to write at-least two controllers for each feature.
Second if we breaks the application in Areas (as modules) how i will manage Admin task for each Area.

We have a timer process (a JQuery plugin) that redirects after X number of minutes to the login page, all via JavaScript. When the timer hits zero, I want to run a task (could be anything; however, in this specific scenario, it's a web service call).
So the process does:
if (zeroedOut) {
window.setTimeout(function() {
//Run finish-up processes
}, 0);
window.location = "login.aspx";
}
The issue I'm having is the web service that runs with the finish-up processes is not being called. The web service call happens, the redirect happens, I don't see any errors (I have try/catch statements around the setTimeout call), but no WS call.
