• What are the requirments for ISupportInitialize code to be serialized in InitializeComponent? .Net

  - by Jules

  I need to add some code to the EndInit method of a PictureBox control but unfortunately its private and, from what I can gather, I can't shadow it and call base - at least not in VB.Net. What I can do is add a dummy property to my picture box class. The type of the dummy property is simply a class that just implements ISupportInitialize. However, that doesn't work, I need the dummy class to inherit from Control. Is that the minimum requirement?

• Is ASP.net MVC a direct copy of Ruby on Rails concepts?

  - by Greg

  Hi, I'm been developing Ruby on Rails previously. I'm now looking at an ASP.net web app and I'm looking at WebForms and MVC. As I look at MVC it feels as if I'm looking at the result of something a Ruby on Rails developer implemented after being forced to work in MS land. So I'm wondering: Was MVC more or less taken directly from Ruby on Rails and it's concepts? (either intentionally or unintentionally)
