Is there a way to enforce a class only to be used in ASP.NET ? So that it can't be referenced in a WinForm app or throw exception when instantiated. Is there some kind of .NET class attribute for this purpose?
I have a validation attribute that inherits from ValidationAttribute. However, the particular usage of this attribute applies to lists only (IEnumerable really). How can I specify the usage of this property to only be used with items that inherit from IEnumerabe?
We have a web application based on asp.net 1.1. We deployed it on a web server but there is a problem about it. In the webserver sometimes cpu usage is increasing to 100% and outofmemory exception is occuring.
I think there are some wrong code inside the project but i don't know where it's.
Now, i want hear your advices about how to find problem and what kind of codes make cpu usage increased.
I have a web server with more than a few ASP.NET sites running on it. Every so often, i notice that IIS is pushing the server's CPU to 100%. The sites share application pools, per .NET version they are running.
What i'm looking for is a way to be able to pinpoint which site it is that is doing this, using some tool. If that tool happened to get down into the code to show it, that would also be nice. If not, i'm happy just knowing which site is causing the issue.
I've already tried using ANTS. However, with ANTS you need to know which site it is, and then have it running and waiting on said CPU-crashing web app. Not perfectly ideal.

usage of asp.net server controls in asp.net mvc. The question is like can we use asp.net server controls in the asp.net mvc? If asp.net server controls cannot be used in asp.net mvc is it a limitation of asp.net mvc model? If it is a limitation then how to use more number of controls(like asp.net server controls)

I'm running a Windows 2008 server (a VPS with 1GB of RAM), with SQL Server Express and IIS 7 installed. On it I'm hosting a NopCommerce 1.7 website, with a database of around 26 000 products.
Right now I'm the only user of the website (it's in development) and I'm getting rather bad performance from it. To be more specific every time I make a request, the worker process goes to 90-100% CPU usage for a few seconds. Is it me or this is a lot for a 1 user NopCommerce website?
PS: the worker process uses between 100MB-400MB of memory (private working set), and SQL Server with this database, around 160MB.
We have a web application running which having around 100 users logged in, All clients are connected to server using websync. I was having requirement for keeping the session always live, so I am regenerating session when it is about to expire.
But after 3 or 4 days, I found cpu reached to 100% and application locked, then we need to restart the server to make it working.
The web app uses XML from a web service, which is then transformed to HTML using XSLT. The app uses a HttpModule to get the XML using AddOnPreRequestHandlerExecuteAsync.
Classes Used:
XmlDocument - stores the xml. XslCompiledTransform - stores the transform, is cached in Application. Asynchronous HttpWebRequest using BeginGetResponse/EndGetResponse HttpModule with hooked AddOnPreRequestHandlerExecuteAsync events.
I do not want to use the XPathDocument unless there are no other possible optimizations. It would take some complicated code to get all the XML together without the ability to write to the XmlDocument. There is additional XML that does not come from the web service that must also be added to the document.
I have really tried to Google it but only articles about how to troubleshoot memory issues come up. Before I start to troubleshoot, I would like to know if my web site's memory usage is really abnormal or not.
So it is an asp.net mvc 2 website that runs on IIS 7.5 in production. I guess normal memory usage depends upon traffic, so here are the numbers of an average day:
300 unique visitor 400 visits 3000 page views
I would be really happy to get some idea how much is the normal memory usage for this traffic. Also I would be curious to know how memory usage normally increases with traffic growth.
I want to use an iframe in my project.. I'm using Visual Studio 2005 using asp.NET and VB.. I created the iframe okay.. but here's the tricky part.. I have a variable in the VB CODE called "htmladdress" and from the VB CODE i wish to do the following example:
[Code].... how either I access the iframe from the VB CODE (preferably) or access the variable from the asp code.
I have a member class that returned IQueryable from a data context
public static IQueryable<TB_Country> GetCountriesQ() { IQueryable<TB_Country> country; Bn_Master_DataDataContext db = new Bn_Master_DataDataContext(); country = db.TB_Countries .OrderBy(o => o.CountryName); return country; }
As you can see I don't delete the data context after usage. Because if I delete it, the code that call this method cannot use the IQueryable (perhaps because of deferred execution?). How to force immediate execution to this method? So I can dispose the data context..
I'm learning EF now and have a question regarding the ObjectContext: Should I create instance of ObjectContext for every query (function) when I access the database? Or it's better to create it once (singleton) and reuse it? Before EF I was using enterprise library data access block and created instance of dataacess for DataAccess function...
