@Juan Manuel Did you ever work in classic ASP? When you had to program all of your own events and "viewstatish" items (like a dropdown recalling its selected value after form submission)?
If so, then ASP.NET MVC will not feel that awkward off the bat. I would check out Rob Conery's Awesome Series "[MVC Storefront][1... |

One useful strategy to keep in mind might be the [composite pattern][1]. At a low level, it might allow you to treat all GUI objects (and collections of objects) more easily once built.

Assuming that in your first example apps is an IEnumerable<Process> you could make use of the .Count and .FirstOrDefault properties to get the single item that you want to pass to SetForegroundWindow.

I found Ted Jensen's "Tutorial on Pointers and Arrays in C" an excellent resource for learning about pointers.

I think looking at the way other GUI toolkits have done it would be an excellent place to start. For C++ examples, I hear lots of good things about [Qt][1]. I haven't used it personally though. And of course WxWidgets as Nick mentioned.

@FryHard FirstOrDefault will work but remember that it returns null if none are found. This code isn't tested but should be close to what you want:
var app = Process.GetProcesses().FirstOrDefault(p => p.ProcessName.Contains("MyAppName") && p.MainWindowHandle != IntPtr.Zero);
if (app == null) return;

Well, you can already lock up a browser and *seriously* slow down a system with badly-behaved JS. Enlightened browsers have implemented checks for this sort of thing, and will stop it before it gets out of hand.
I would tend to assume that threads would be dealt with in a similar manner. |

I would probably use struct as the type, and then throw an exception if it isn't an Enum type. I don't see how your (Type, string) option is any safer than using object or struct. |
