I'm trying to use a dummy TempDataProvider for some of my controllers.
The provider looks like this.

But I'm getting an error that says
System.NullReferenceException: Object reference not set to an instance of an object. at System.Web.Mvc.Controller.PossiblyLoadTempData()
For some reason, with the Razor view engine, VS is crashing on me. I copied the CSHTML content over to a VBHTML file and begin reformatting it, and VS has crashed on me twice now as I change a helper or function method syntax from:
@helper SomeHelper(string text)
to
@Helper SomeHelper(text As String)
The whole machine must be rebooted to get intellisense/markup highlighing to work.
i am inserting the value of dynamic controls into the db like so;
Dim ae1 As DropDownList = FindControl("AreasExpertise1")
If (ae1 IsNot Nothing) Then
x.Parameters.AddWithValue("@areasexpertise1", ae1.SelectedValue)
End If
then in my query i have parameters like so;
INSERT INTO [foo] ([etc], [etc], [etc], [areasexpertise1], [areasexpertise2])
VALUES (@etc, @etc, @etc, @areasexpertise1, @areasexpertise2)
When the user fills out the form, they see only areasexpertise1 and have to press a button to dynamically insert another area of expertise...If they only have 1 area of expertise, the query crashes and says 'must declare variable @areasexpertise2.Please can you tell me a way to either insert nulls when the parameters are empty, or to ignore them?
One of the projects I'm working on crashes the development server everytime I go to compile and run, or preview a page.
It's only just started happening, and I really need to resolve it.
My ASP.NET program works fine for 30 mins (approx) then crashes with the generic status code 500. I've reviewed my code and can't seem to figure out what the problem could be. The program is running under II6 and I'm using .Net 2.0.

View 2 RepliesI have a page with an iFrame whose source is an ashx page. The handler takes in 3 arguments through the query string and generates a text/html response containing a table. When the table gets >1700 rows it crashes the IE8 browser. The browser freezes and returns a null reference error.If I take the html that is being rendered and place it inside a DIV on the page it renders fine in IE8.
View 3 RepliesI have web applications which were developed before I installed during mid week last week the SP1 from Web Platform Installer and MVC3. My applications currently still use MVC2. When I open Site.Master, the VS2010 would crash every time and tries to restart. The problem doesn't apply to .aspx, ascx, or other extension. Does anyone have the same problem? Here is what I have done to my computer:
1. Installed MVC3
2. Installed VS2010 SP1 and associated components using Web Platform Installer (install failed several time, but succeed this morning)
3. Modified myProject.csproj file using NotePad to change <mvcBuildViews> from false to true

View 2 RepliesI'm working on a "Website Project" (as opposed to an ASP.NET Web Application) which we received from another company as part of an acquisition.In general it works fine, however every time I close the project ("File" -> "Close Project" or just "File" -> "Exit"), the IDE crashes.If I create a new project this doesn't happen, and it doesn't happen for any other project/solution file I have handy.The other information I have that might be useful is that this project may have stared out as a VS2008 project, and previously it was under Microsoft source control (it's under Subversion now).

View 1 RepliesI have a web form with a whole bunch of drop down lists (mainly) that works perfectly well and has been for some time. However, we've found a scenario that seems to corrupt the viewstate of this form in someway, or cause it to lose it's viewstate. The problem occurs when the user has this form displayed, then clicks on a link that opens up another window. A few more steps to open up a second and third window, followed by a write to the database. Then the user closes these windows down, leaving this original window open. At this point, the user selects something from one of the dropdowns. And the app crashes because the dropdowns have lost all of their values (and so a bit of code that is trying to work with one of the ddl's selectedvalues fails).
When the user selects this dropdown, the page_init event fires, followed by the page_load with postback = true. The dropdowns themselves are defined in the aspx page markup, but the values of them are generated and added in page_load (where postback = false). I've relocated the code to populate these controls to the page_init code and now the app doesn't fall over, because the values are re-populated. However, all of the selectedindexes are being reset, so the original values are lost and the screen redraws after this postback with all of the dropdowns reset.
I can't believe the number of issues that seem to work fine on test but completely crash and burn on production.I have a situation where the code works fine in the test/development environment, but when you press a button in production, it crashes with:

Its just a button push, that is suppose to rebind a quantity change back to the database that the user has changed in a textbox in Gridview Edit.

Adding any other attribute works fine.
I am ruuning VS 2008 on Windows XP Service Pack 3. The problem I am facing is that my windows crashes after a blue screen whenever I run a website in VS2008.Its only with websites projects in VS2008 but not with WinForms projects. WinForm applications running without any problem.This happens in this sequence that when I run the project, it starts, debugs and port is opened for my project (a popup that comes right near the system clock in taskbar) and suddenly after that a blue screen comes and Windows restarts. After restarting,
a message comes that system has been recovered from a serious, send report to Microsoft blah blah blah...Can anybody figures it out what problem there can be?
I have static content like html,css javascript stored in DB. when a user requests for these i create a temp file in virtual directory and return the url. My web app is hosted on a IIS server. On some systems on creation of a file my IIS Application pool crashes and restarts. If i disable file-monitoring though the problem is resolved, but i dont have this luxury when i am deplying at the client end. Is there any way by which i can avoid app pool crash during file creation? If not is there any way by which i can serve static content like html, css, images, xml and js without creating temp files. I would need a generalized way of handling all these data types.
View 1 RepliesI have a Formview control that has several lookup fields. The value is an int ID but the textfield is the name, e.g. value = StateID, displayed text = StateCode)
If the user leaves that field blank, I get a Server Error when attempting to Update: Failed to set one or more properties on type orgOrganization. is not a valid value for Int32.
In the table for the LinqDataSource which provides the data for the Formview, all fields except the text field OrganizationName allow Nulls.
Does anyone know why this might be happening? I tried a test which just has the numbers, no lookups, and get the same result.
If my dataset contains any null values, then the 3D stacked bar (or column) chart crashes with the "Index is out of range" error.It works fine for 2D for the same data set.
View 1 RepliesVisual Studio (SP1) runs fine until I try and view .aspx source files with the lines

I have read a lot of questions about Visual Studio 2008 crashing on viewing some source files. However, I still can't fix this problem.
I have systematically deleted and re-included all other code and it comes down to these two lines, which is very confusing. Sometimes it happens as soon as the lines are added, sometimes it doesn't freeze until I build the solution with any of the problem pages open. I can add external style sheets, and it only started recently.
I had Resharper 4.5 installed and have since uninstalled it, and do not have anything else installed.
Also, it happens to other people with the same source code, and re-installing Visual Studio does not fix the problem. So I have several questions:
Is there any way I can find out what's happening? I don't understand how the code (the css tag itself) could crash Visual Studio, and am thinking that this is unlikely and it must be something else within my solution, would this be a safe assumption? Could this have anything to do with installing Office 2010?

I have a CLR 4 WCF service hosted in IIS 7.5 (Windows Server 2008 R2), using the WebHttp binding (with [WebGet]). The service calls into an unmanaged component implemented in C++ (Visual Studio 2010). I deliberately added an access violation inside the unmanaged component (by calling delete on a pointer repeatedly, calling methods through a deleted pointer, etc.) to test dump file generation settings. The access violation crashes the w3wp.exe process, which is not surprising considering "Corrupted State Exceptions" in CLR 4. However, when the process restarts (due to warmup and always-on settings in IIS), the same request seems to be replayed to the service so that it crashes the w3wp.exe process again. After a few times (governed by the "max failures" application pool setting) the application pool is stopped.
I'm using the browser as the test client, and while the restart sequence is underway the request is still in flight. When the application pool is stopped, the request returns with 503 Service Unavailable. I can work around the problem by placing try...catch block around the code and using the [HandleProcessCorruptedStateExceptions] attribute. When I do that, the w3wp.exe process does not crash. However, this is not the desired behavior -- I want the process to crash (an access violation or a memory corruption is bad enough) but I want it to restart into a clean state and not have the request replayed. I was not able to reproduce the problem using the BasicHttp binding.
My GridView is bound to a sql data source and allows editing of fields. Coding is in C# and JavaScript.
Using Visual Studio 2008 in test mode, if I enter a less-than "<" or greater-than ">" character in a GridView textbox an error is immediately thrown upon pressing enter:
"Microsoft Visual Studio Mirosoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status dode returned from the server was: 500"
When the < or > is entered in production, the page aborts and loads the application start page.
I need to be able to catch and replace those characters BEFORE the error is thrown. I've tried hooking OnTextChange code to the textboxes, but the error is thrown as soon as I press enter...the OnTextChange code never runs.
