Now, one of the key activities in the organization is the one that includes ...
I was trying to use ajax to retrieve data from a repository using a controller and I kept getting Internal Server Errors... I've whittled it down to the line: private MyDBEntities _myDB = new MyDBEntities(); That's located in the repository, without that line I don't get the Internal Server Error. The line is called after the Reposito...
I've got an ASP.NET MVC (VB) project with two models that represent two different databases. Each model needs to include a table from its database with the same name. For example, model1.dbml needs to have db1.MyTable in it, and model2.dbml needs to have db2.MyTable in it. I can't do this because both models try to create a "Partial Pub...

I also have a MainWindowViewModel class that contains an observable collection of DiceViewModels. When a user clicks the "Roll" button, it launches a ...
I have a very large list Suppose I do that (yeah, I know the code is very unpythonic, but for the example's sake..): n = (2**32)**2 for i in xrange(10**7) li[i] = n works fine. however: for i in xrange(10**7) li[i] = i**2 consumes a significantly larger amount of memory. I don't understand why that is - storing the big number t...
I notice a lot of the examples for ASP.NET use Linq2Sql as the datasource. Are there any examples out there which show how do use model binding with a non-Linq2Sql datasource, ie a dataset, or (as in my case) a generic list/collection of items based on a custom business object? ie public class WebsiteList : List { public WebsiteLi...
In the Zend Framework Quickstart, there has been a change from models that extend Zend_Db_Table_Abstract to the Table Data Gateway pattern. Personally, I have not had much experience with this pattern and I keep hearing this should most likely be used instead of the old way. A short example from the quickstart: Old way: class Default...

I have to write kind of a complicated query to get some statistics for the rules in our system for each Agency we have in our database. It looks something like this: There will be an arbitrary number of columns (rules) and rows (agencies) for this data. For example, here there are 5 main rule columns shown, but this could just as eas...
I've been using a pattern in an application where I'm setting arbitrary attributes on Expando class models in an App Engine app. This works as expected, but hasn't yet been tested with a really large data set. And over time, the number of attributes might get to be > 1000. It also makes the table in the administration console scroll fa...
So I have a MVC app and in another project I have a normal collection of classes which handle the Business and Data logic for the application. I also have some logic in the Model of the MVC project itself. This logic handles ViewModels and the like, things which could not have been done in the n-tier project as they relate to the MVC pro...

I set things up so that after an address is added, the users sees the address in an update form with a "save" and "delete" button. The user can adjust any of the addresses they have added. The proble...

I'm modeling a very basic ASP.NET MVC app using NHibernate and I seem to be stuck on my design. Here's a sketch of my model: As you can see this is VERY basic but I have some concerns about it. The User root entity and the Organization root entity are accessing the same Organization_Users entity child via two one-to-many relationship...
