I'm maintaining an in-house ORM written in C#, and it currently does not have any eager-loading mechanism. To improve performance, we decided that it would require eager loading so we need to write our own code to support that. (My colleagues and I do not have any experience with any ORM tools, and furthermore, due to some legacy reasons...

Say I need to design an in-memory service because of a very high load read/write system. I want to dump the results of the objects every 2 minutes. How would I access the in-memory objects/data from within a web application? (I was thinking a Windows service would be running in the background handling the in-memory service etc.) I want...
I have a project consisting of a windows client (approx. 150 users), a webservice and some windows services. All together working in an intranet and build using C# .NET 3.5. Now I want to log exceptions in a central database and manage them (watch top 10, ticket system, etc.) via a web application. I thought about using and expanding EL...
For a reference type, the object's memory layout is | Type Object pointer| | Sync Block | | Instance fields...| For a value type, the object layout seems to be | Instance fields...| For a reference type, GetType means find the object from the 'Type Object pointer'. All objects of a given reference type object point to the...

Ordinarily I wouldn't just post an error message on SO, but after a Google search only found one hit, I thought I'd at least open the floor for this error here on SO. I have a custom control called Sparkline with a dependency property called Values of type unit[]. Here's an example where I use it in a DataTemplate: <DataTemplate DataT...

I'm using VB.Net in an ASP.Net 2.0 app to run some regular expressions that remove some unnecessary markup. One of the things that I'd like to do is remove span elements that don't have any attributes in them: output = Regex.Replace(output, "<span\s*>(?<Text>.*?)</span>" & styleRegex, "${Text}", RegexOptions.Compiled Or RegexOptions.Cul...

This is related conceptually to my question here. However, I've been playing around with NHibernate, and realized what the real core of my question is. In classic OO design, to properly encapsulate data, it's a common pattern to have values passed in to an object's constructor that are stored in data members (fields). Those values whic...
I'm looking at a web application with a Response.Redirect between two Https pages. I would assume normally that the query string parameters aren't visible for https requests because of the secure connection. However, since the Response.Redirect sends back the 302 - Object Moved response in between the two pages along with query string va...

I found on Window object StateChanged, but it fires when Window object is already in Minimize state, then it's too late. So, I need something like "StateChanging" event to handle, while Window object is still in previous state. Is it possible t...

I am trying to use reflection to determine which methods a derived class overrides from a base class. It is fairly easy to determine if the method is not overridden, but trying to determine if a method is overridden in a base class, or simply created as virtual in the derived class is what I am trying to accomplish. So, if Class A has ...
Hello, I am writing a WinForms application in C#. At one point in the application, I spawn a new STA thread (create thread, then SetApartmentState) that creates a new form and then shows it with plain old Show(). The form itself contains only a docked DataGrid whose DataSource points to a DataTable retrieved from a newly open SqlConnect...
