How to detect if items are added to a ListBox (or CheckedListBox) control
This seems like a fundamentally simple question. I have a WinForms dialog box with a listbox. This control is not populated via data-binding but is filled with calls to listBox.Items.Add (obj); It is possible that this call can be made asynchronously from various places and I would like to hook the listbox and watch for changes in it...

GAC vs JIT
Is everything under the GAC precompiled (ngened)? If so, then all of .NET is precompiled, so it's not possible for the CLR to optimize them at runtime? Like if you use List in your application then CLR will not be able to optimize the List itself, but only how it's used in your app? Doesn't this defeat the purpose of JIT, to get lots of...
How to capture XMLHTTP requests in a Webbrowser Control?

Building a CMS in ASP.NET MVC
I'm curious to know if any basic CMS code has been written for ASP.NET MVC. The reason I ask is, I'm making a data-driven website for a client, and I've already spent a significant amount of time building it from the ground-up in MVC, but now the client wants content management facilities. Basically they want to be able to add/edit/rem...
