I am a newbie to the Entity Framework. I am trying to generate a model from my database and I get the following errors: '_Content' is already declared as 'Private _Content As Integer' in this class. 'OnContentChanging' cannot be declared 'Partial' because only one method 'OnContentChanging' can be marked 'Partial'. 'OnContentChanged'...
I've done it both ways, and to be honest other than the ability to give the code and webform to two different people (which doesn't happen where I work), I see very little advantage of one method over the other. I can understand how it is nice to have your code in one file, and markup in the other, but I can also understand the ease of h...
I am currently deploying my application built using RC of MVC ASP.NET on the production server which is showing nothing now. The routes in my global.ascx are typical i.e. routes.MapRoute( "Default", // Route name "{controller}.aspx/{action}/{id}", ...
I'm wondering if it is possible to determine if a user already has a web browser open to the web application I'm working on. It seems that they can open several instances of the same web app and click on buttons to read information that they have used before to enter into an input screen that they're currently working on. What happens t...
The following works in IE, but not Firefox: var el = $get('divToMask'); var box = Sys.UI.DomElement.getBounds(el); var maskEl = $get('maskDiv'); // Only seems to work in IE maskEl.style.width = box.width; maskEl.style.height = box.height; Sys.UI.DomElement.setLocation(maskEl, box.x, box.y); box.width and box.height contain the corr...

Actually I changed my job due to some problematic situation in the company. When I was facing these problematic situations my frined offered...
I'm building a decent sized application in ASP.NET/VB.NET with various objects... I've never used interfaces before, and a fellow programmer balked when I mentioned this to him. Can anyone give me a quick overview on how they're used, what they're used for, and why I would use them? Maybe I don't need to use them for this project, but if...
Hello, In an n-tiered application where you are using custom entities, how do you find yourself handling data needed from lookup tables? Do you create entities for each of these lookup tables or employ some other strategy? For example. I have a "Ratings" lookup table that will be used to populate a dropdownlist. Would you create a ...

What is the preferred method for handling exceptions in ASP.NET Webforms? You have the Page_Error method that you add (I think) at web.config level, and the entire site gets redirected there when an error occurs. Does that mean you shouldn't use try-catch anywhere in a webforms application? (Assuming you don't want to hide any errors) ...

I was wondering if anyone could point me to some resources concerning customization of the user management system that is built in .NET. What I am talking about is: http://msdn.microsoft.com/en-us/library/ms998347.aspx I would like to know, how can I extend the user fields to store more than just common password, username? I want to s...
I've have an asp.net web app, forms authentication, that's uses Hashed password type. Will I run across any problems if I change the password type to Encrypted? I see that, if I change to Encrypted, attempted password recovery for old hashed passwords fails gracefully, which is good. Are there any not so good things that might show up ...
I have a bunch of simple lookup tables cached in my asp.net application since the source data is on a seperate server from our main web architecture and it changes infrequently.
