.net - Effect Of Implementing IDisposable On Classes?

Aug 2, 2010

I running my static analysis checks again and I'm getting 100s of nags on

Label foo = new Label(); //Where this is an ASP.NET web forms label

Do I need to call dispose on these web forms labels? Also, how late in the page life cycle is it safe to call Dispose on these? If a class implements IDisposable, but doesn't actually do anything in it, is there any harm in not calling dispose?

(Yes, I have already read that closing connections is a good thing and using blocks are a good thing, too.)

DataSet is another class that seems to implement IDisposable for inexplicable reasons.

Visual Studio :: What Is The Difference Between Designer Classes And T4 Template Generated Classes

Jan 11, 2010

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?

C# - Class Structure With LINQ, Partial Classes, And Abstract Classes

May 17, 2010

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:


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).

C# - Can Base Classes See The Protected Fields Of Derived Classes

Aug 11, 2010

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.

Map Model Classes To ViewModel Classes Or Aggregate Model Classes In ViewModel Classes

Dec 15, 2010

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?

ViewState, QueryStrings And Their Effect On SEO?

Oct 7, 2010

I'm a novice ASP.Net/C# programmer, and had an experience only of a couple of projects during college and a couple of freelancing projects when I was recruited by a startup company to build their ASP.Net based website. I've just abut completed the website, and now since the company is not able to find a worthy enough SEO, I'm expected to do our site's SEO as well(which is a totally new experience for me). Did I mention that I'm the only Web Developer here?So, now as you'd expect a novice programmer having no concern for future SEO needs, I built up the site without giving due consideration to any of the SEO enhancement techniques.

The Problems:

ViewState - When is it required? Is it really required if I'm not creating any controls on the fly? I'm using DataControls though. And the website(the pages visible to the user not the CMS), is purely information based. Also, if I disable a control(ex: DataList)'s viewstate, will the viewstate of controls inside it also get disabled?(which is what I'd like actually)QueryStrings - Now comes the toughest part, I've used Query Strings to the extent that you can say that the website is QueryString driven, which unfortunately enough is not a good thing for SEO. To make matters worse, the QueryStrings for some pages are not uniform. For ex- In some cases the querystring may have variables A, B, and C, while in other cases it can have variables M, B, C and probably not all the three variables in some cases. Now, I know that I'd have to do url rewriting but these query strings have dynamic data fetched from the database tables of size more than 10,000 rows. So would I have to create functions for url rewriting and use regex to separate wheat from whaff?

C# - Changing AppSetting Does Not Have Effect On Application?

Dec 11, 2010

In one of the application i am developing on ASP.Net. In this application we have been using lots of AppSettings. In the initial development we used ConfigurationManager.AppSettings[""]. but as development progressed we created a utility class in which we would define a static property for each AppSettings. Then issues started to come. Now when application is deployed on testing server and we change any settings on AppSettings it does not have any effect unless we restart the IIS. here is the following code snippet i am using to create static property of AppSettings.

public static class AppSettingsUtil
public static string Log4Net
return ConfigurationManager.AppSettings["Log4Net"];

Unable To Rewrite Some URLs For Masking Effect?

Oct 22, 2010

I have an application where I rewrite some URLs for a masking effect. If I run the application through VS, it works fine. However, when I try to run it through a virtual application, it says:

Could not load file or assembly 'MoonFlareStudiosLibrary.UrlRedirection' or one of its dependencies. The system cannot find the file specified.

MoonFlareStudiosLibrary.UrlRedirection is the code namespace that handles all my url redirection and rewriting.

When I say "run it through a virtual application" I mean I use IIS7 to create a virtual application in my wwwroot folder so I can just type "localhost/<app name>" to run it.

hy it work when debugging but not through the virtual application?

Is it possible from the 2nd usercontrol to call a clientside function within the page so I can have a similar effect as a modal popup?
