View 3 RepliesI've a view which display all data. I'm using ViewData, for loop etc.. on the view, to show the data. It may sound weird, but is it possible to write view to disk as a file instead of showing in the browser. The reason is that, business wants functionality to send the same view file as email attachment to the user.
View 3 RepliesI have an httpmodule and it has a handler for OnEndRequest. I am trying to write the HttpContext.Response.OutputStream to a file. I am trying to use the Read method of it. But when it is called the exception message i get is "Specified method is not supported". So i am not able to do what i want that is, write the response to a file on the disk. I am able to write the HttpContext.Request.InputStream to a file using its Read method which i do in a handler for OnBeginRequest.
View 2 RepliesWe have had complaints of users losing data that they entered in textboxes in our ASP.NET 2.0 web application. Users are authenticated using Web Single Sign On method. My boss would like to save the client data in a file on their local disk in case they lose connectivity. I know this is not allowed with the default security of ASP.NET.
Would it be possible to programmatically change the ACL permissions for the NETWORK SERVICE account to access the isolated storage folder on the logged in user's local disk? Is there a better way to achieve this goal of persisting user data to a file?
I am testing with an MVC 2 project generated by the template in VS 2010. I have simply added an ADO.NET Entity Data Model, as well as a WCF Data Service that leverages the data model.
I was able to access the web application content (views, as well as the data served by the data service) just fine until the day before yesterday.
Yesterday I decided to reinstall Windows 7 on my development laptop, and I chose to go with the release of the OS with SP1. Of course, I reinstalled Visual Studio as well.
Now the same project gives me HTTP 404 errors when I try to browse to the data url .../MyTodoDataService.svc).
Here are some interesting facts:
The same data service works just fine in a Web Forms application. I see the problem only when deploying to the Local IIS Web Server (Cassini runs it just fine).
I am able to browse to the data url if force MVC routing to ignore the appropriate route by calling "IgnoreRoute" on the RouteCollection in Global.asax.
I have an app configured to use anonymous authentication, the application pool is set to network service. When I run filemonitor I can see that thw w3wp.exe is picking out the webpages and stuff from my hard drive and returning images etc. However one of the pages saves a file to a folder using c# save() method. Instead of the w3wp.exe actually writing the file to disk explorer.exe seems to be accessing the folder. What the hell is going on? I though the w3wp.exe did everything asp.net related why on earth is explorer.exe being introduced into the fold here?

View 1 RepliesWe have an ASP.NET MVC site that uses Entity Framework abstractions with Repository and UnitOfWork patterns. What I'm wondering is how others have implemented navigation of complex object graphs with these patterns. Let me give an example from one of our controllers:
[code]....
It's a registration process and pretty much everything hangs off the POCO class Person. In this case we're caching the person through the registration process. I've now started implementing the latter part of the registration process which requires access to data deeper in the object graph. Specifically DPA data which hangs off Legal inside Country.
The code above is just mapping out the model information into a simpler format for the ViewModel. My question is do you consider this fairly deep navigation of the graph good practice or would you abstract out the retrieval of the objects further down the graph into repositories?
Does anyone have a working pattern for converting a GET-POST-GET pattern to asny?
I'm encountering the following issues:
1. You cannot mix Sync and Async action methods SubmitForm(), SubmitFormAsync(bool? confirm), SubmitFormCompleted() ... (because the resolver gets all confused ... it doesn't use the HTTP verb to decide who to target. BTW: I think that's poor design, or a bug)
2. Renaming the get method name to something else eg: SubmitFormConfirmation(), SubmitFormAsync(bool? confirm), SubmitFormCompleted() would be very awkward if it works ... because you have to doctor the <form markup to specify an action name.
3. You cannot give them all async names SubmitFormAsync(), SubmitFormAsync(bool? confirm), submitFormCompleted(), because the call just keeps malfunctioning. It sometime even behaves as if you are requesting a delete of something.
Can someone give an insight from an actually working sample.
Now that the next version of ASP.NET MVC is being prototyped and previewed (ASP.NET MVC 3 Preview 1 came out a couple of weeks ago), I wonder if we should call the attention of the Core Dev team (S Hanselman, Phil Haack and all) to this "feature."there a easy/non tacky way of associating subdomains → areas?Something like:

how to write two files using Response.WriteFile?
I tried the following
Response.AddHeader("Content-Disposition", "attachment; filename=" + textFile);
Response.Flush();
Response.WriteFile(FilePath);
Response.End();
streamWriter2.WriteLine(CodeFileText);
streamWriter2.Close();
Response.AddHeader("Content-Disposition", "attachment; filename=" + textFile2);
Response.Flush();
Response.WriteFile(FilePath2);
Response.End();
But it downloads the first and stops.
It doesnot go for second one.
I'm trying to add functionality to a simple web service that will allow me to log information to an XML file on the hard drive where the application is located. When I employ the functionality in a Console version of the application, the data gets logged to:binx86Debug MySolution.MyProjectMessageLogTestMessagess.xml. However, when I try to write read from or write to the XML file in the ASP.NET application, I get a System.UnauthorizedAccessException with the message: Accees to the path 'MessageLog' is denied.I would like the log file to appear in the in folder of the application directory, so what settings in IIS or on the server itself would I need to change to allow my application to read from and write to that folder?

View 3 RepliesSuppose we want to select the data from the database then we write the query for that. Example:
SqlConnection con=new SqlConnection(Connetion name) string selectPkId = @"SELECT PK_ID FROM TABLE" SqlCommand cmd=new SqlCommand(selectPkId ,con);
So,my question is that why we basically use @ before the sql query.If I don't use @ before that then it again work fine (does not give any error), then what is need of using "@"?
I am reading in a file into a string. Then I am writing this string to a stream. I know this code works fine.
