I converted a ASP.Net website to ASP.Net web app and changed the framework from 2.0 to 3.5
The web application works fine in Visual studio. However, If I compile the app in a dll, and try to reuse its middle layer in another web project, All the classes that have a static variable crash. Code like:
After upgrading an asp.net application to 2.0 from 1.1 I am receiving a large 100+MB .tmp file in C:Temp on the web server when the w3wp process serving that application crashes. If you open the file it looks like it is some sort of dump file. how to turn this off. I know what is crashing the application and process.
i have classes of my web application only the default one work if i for example click a link to go to another class i get this error for each class this happens . But only on the web server WHy ?
Server Error in '/' Application.

I have a large asp.net project to which I want to add MVC functionality. I have added the necessary references into the project (System.Web.Mvc (v 2.0), System.Web.Abstractions (v 3.5) and System.Web.Routing (v 3.5) and amended all the required files (Global.asax (routing requirements), the web.config, project (Controllers and View folders) and created a basic HomeController and ViewPage.
When I run the application and attempt to go to the controller via {serverpath}Home I am getting the error "An unhandled exception has occurred - Could not load file or assembly 'System.Web' or one of its dependencies. The system cannot find the file specified." I've tried browsing the net but the error is too vague; is there a good way to identify exactly why the assembly cannot load?
As the subject reads, how can i accomplish this ? All my webforms inherits from a class called "BasePage". It can also suffice with only getting a list of all the webforms in the application, regardless of base class since i can check inheritance later in code.
Reason i'm asking is because i'm building my menu and i'm implementing security enforced user visibility based on what pages there are in the webbapplication, and what roles each page demands, and display these to the user in the menu.
Using sitemaps are insufficient, i need to provide much more info for all the pages i have on my system.
Using this technique i can query my "PageProvider" for like:
I am new to LINQ. when we drag tables we get a dbml file and designer file.
For example DataClasses1.dbml and DataClasses1.designer.cs.
Once we have them then we can start using our LINQ Queries.
In my company project I do not see this designer files and instead there are .tt files which were used as templates to greate ABC.generated.cs files. Is this same as designer class?
I am following the Nerd Dinner tutorial as I'm learning ASP.NET MVC, and I am currently on Step 3: Building the Model. One part of this section discusses how to integrate validation and business rule logic with the model classes. All this makes perfect sense. However, in the case of this source code, the author only validates one class: Dinner.
What I am wondering is, say I have multiple classes that need validation (Dinner, Guest, etc). It doesn't seem smart to me to repeatedly write these two methods in the partial class:
[code]....
This doesn't "feel" right, but I wanted to check with SO to get opinions of individuals smarter than me on this. I also tested it out, and it seems that the partial keyword on the OnValidate method is causing problems (understandably so). This doesn't seem possible to fix (but I could very well be wrong).
I don't know if this has to do with how FindControl works or how scope works. But my base class is having a hard time seeing the fields of child classes. Currently I'm planning have the derived class set a property in the base class, but there are a lot of derived classes, so that isn't a very attractive solution.
Our ASP.NET 2 web application handles exceptions very elegantly. We catch exceptions in Global ASAX in Application_Error. From there we log the exception and we show a friendly message to the user.However, this morning we deployed the latest version of our site. It ran ok for half an hour, but then the App Pool crashed. The site did not come back up until we restored the previous release.How can I make the app pool crash and skip the normal exception handler? I'm trying to replicate this problem, but with no luck so far.Update: we found the solution. One of our pages was screenscraping another page. But the URL was configured incorrectly and the page ended up screenscraping itself infinitely, thus causing a stack overflow exception.
I'm curious as to what people consider better practice, between duplicating model structure in the view model and using a mapping tool to move data between the two, or aggregate the model inside the view model, i.e. have a property on the view model class that is a reference to the actual model. Which is considered a better approach in general?
What is happening is I'm trying to process international characters, but the code is falling through (giving up?) and replacing the field with a blank (well, I guess the screenshot is at the bottom)... The customer recently asked for support for Polish characters, and gave us a list of which ones he wants added.
This is the entire function:
Code: Protected Function chkExtchars(ByVal name As String) As String Dim j As Integer = 0 Dim dt As New DataTable Dim c() As Char = Nothing Dim n As Integer Dim nc As Char Dim newname As String = "" dt = HttpContext.Current.Session("xChars")
[Code] ....
But maybe it needs to be sequential? (the numbers on the far left?)
I just deployed my first ASP app to a remote server (using SQL SErver) and some data entry forms are crashing when the associated table is empty. The PageLoad method is empty, but the error occurs before the page becomes visible. The limited run time error I see says page not found error 404. If I put a record in the table using Mgt Studio, everything is fine. The form contains two LInq data source controls that populate dropdown lists, but everything else was hand coded - no data bound controls at all. There is no attempt to access the actual empty table until the data has been entered and the Insert button is pressed. I have made sure that the tables that use the datacontrols for dropdowns have data in them, even though this should not matter. I did not have this problem on my local machine when developing. In summary, page does not load when table is empty, even though I do not access the table when the page loads?????
This is the entire codebehind file, and yet the page cannot even seem to load.
I have a few years experience developing C#, I have been asked to learn ASP.NET for a web development project. Does anyone know of any crash course tutorials to enable me to achieve this quickly, either internet or literature based?
a look at this site.maimei.chAfter 5 times opening a new site via ajax (fancybox) it crashes in IE?ne little thing is that i load a whole asp.net site via ajax in the new window. so viewstate and other overhead is there twice after. could this be the problem? if yes, why just after 5 times?.is it possible to call just the content of an specific element via ajax? may be just the innerhtml of the body element of the called site?
I have a page that utilizes an IFrame to display another page within the first one. I am using ASP.NET 3.5 and when I click on a button to do a post back event, it causes Internet Explorer 7 to throw an error.
My project uses swfobject.js to display a Flash animation. But in Internet Explorer 8.0, if I try to refresh the page, the browser window closes.
To re-create this problem:
Download a sample solution from: [URL] Unzip the solution and open it in VWD 2010 or VS 2008 Pro Be sure VS is configured to use its development server (not IIS) Select Debug | Start Debugging (F5) When the Default.aspx page opens, press ctrl-F5 to refresh the browser window The browser window will close with no warning or explanation So far, I haven't seen this behavior in Firefox, and nobody has reported it in any browser other than IE-8.
Users get firsly to the step0 page, where they fill some info, the page updates, they fill some more, and then get redirected to step1 page.
Problem is that upon getting to the Step1 page, if the user clicks on the back button, then he gets to the last stage of the step0 page, which uses sessions and variables that are no longer existing, what causes a crash.
I'm looking for an elegant way to make sure that with each page visit, the page will restart itself to start phase.
I have this idea maybe twitching the Page_Load function, something about the is_post method, but since each page's post back hits this function,
I'm trying to bind a nullable bit column, which at the moment is mostly null, but I need to somehow convert the null to a 'false' on runtime because it doesn't bind to a checkbox if it's null. But, I am currently unable to change the default value and update all records accordingly - is there a way to do this in runtime?
I have a page with two data bound list box controls on it. When I there is data in the controls the page crashes and i get "Internet Explorer cannot display the webpage". I have tried to set break points to see what is going on. I have tries to fill the boxes in the code behind instead of using a data source in the page. I have tried setting the page time out to 3 minutes. Nothing is working and I'm not sure what the problem is. The page works fine as long as there is no data in the controls. I'm trying to figure out what I am missing.
Listbox causes page to Crash getting "Internet Explorer cannot display the webpage" Instead of posting your entire code for us to review, could you post the specific portion of the code that you think is causing the problem (probably the retrieval or setting of the data).
I couldnt help but notice that if you have a FileUpload-control, and then try to upload a file thats bigger(in bytes) then the allowed maxiumsize, then the site crashes or some wierd "Connection problem"-page shows up, atleast for me in Firefox...
So my question is simply...is this just for me?..and if not, how do I fix this the best way?...cause the current "crash-page" aint a nice way of handeling the problem in my opinion...whould be much better to actually just show some custom-page that lets the user know that thier trying to upload a file thats way to big..
We recently migrated our ASP.NET 2.0 application to ASP.NET 4.0. It is running on Windows 2003 with IIS 6.0. After migrating, we have found that the ASP.NET 4.0 worker process w3wp.exe crashes intermittently with an 'Access Denied' exception. The stack trace of the exception does not point to any code written in our application. We are clueless as to what could be causing this. The worker process crashes when it makes a remoting call over http.

I have a memory leak somewhere that I cant find. Every few days my server will crash, and just before that I log a ton of SQL errors stating that it is "out of memory".
I cant find it anywhere, all of my connections are being disposed like so:
[Code].... Then I call the connection from my pages like so:[Code]....
That is all pretty straight forward. The connection is disposed because it is implementing the USING clause. I am opening the connection in my connection manager class, and not where it is being utilized?Or, could the problem be in the below method I am using to populate a SqlDataReader:[Code]....
Now, at first it appears as though this could be the problem because the Connection isn't part of a USING clause, however doesn't the 'Data.CommandBehavior.CloseConnection' pretty much do the same thing. This makes sure that the connection is closed when the reader is closed, right? Here is how I call that above reader from my login page code behind:[Code]....
So the DataReader will get closed even without the .Close() because it is in the USING, and the connection should get closed because I specified it in the ExecuteReader paramters right?
