IronScheme - 1.0 alpha 4a out now (29 May 2008)It works with C++? Will I be able to specify a background color of my option? I know that I can modify the HTML, but I'm just asking. I'm downloading it at the moment. Thanks.

Not as nice as C#, but ok :)

Nope, not IIRC, it just defaults to white, I cant remember if it picks up the color from the editor, or if that color can even be changed! Been very long since I wrote that :)

IronScheme - 1.0 alpha 4a out now (29 May 2008)i say double, but one of our new devs, thought it was a bool, then an object, then gave up and had me explain it. person has the same title as me too, funny how i never cared about that stuff until i got one. hopefully the other new guy will do better.
Please remember to rate helpful or unhelpful answers, it lets us and people reading the forums know if our answers are any good.

From what I remember, you're a C++er. Don't worry, you'll pick it up in no time flat, but you'll hate some stuff. const comes as a[n unpleasant] surprise and so do reflection issues. All in all, its a nice language :)

Yes indeed. My portion of our next product (the UI) will be written in C#, since we have a requirement to use some WPF controls supplied by another group. Now, I've got a couple thousand pages of books to read to get started :).

IronScheme - 1.0 alpha 4a out now (29 May 2008)Yeah, makes sense to me, the ternary operator isn't allowed to return different types, so the int is implicitly cast to double, just as expected. Of course I had to add
System.to theConsolemethods to get it to compile... -

Smart? Nah, I give experience credit for this. Also, if you think about it, it has to be this way. Numbers aren't that different from objects in OOP. I think this code makes it more apparent:
(boolval ? new Car() : new AirPlane()).Fly();Since C# is statically typed, method selection can't be left to runtime binding. :)In this case to be able to compile it you'll have to manually cast both objects to a base class, that has a Fly() methods :) While in the example of "? 0 : 0.0" the compiler does implicit casting

IronScheme - 1.0 alpha 4a out now (29 May 2008)D'ohh! My answer was: "System.Int32". (At least I'm being honest!) Although I haven't tested it, in retrospect it makes sense that the two conditional values should be the same type. Good quiz leppie!

IronScheme - 1.0 alpha 4a out now (29 May 2008)The Foo method is expecting a reference type (object), but it is getting a value type, probably double. Now the question is, does C# convert the value type to a reference type (boxing)? The reference type would be converted to a Nullable (double?), I don't think so. I don't think it will return a compile error. So I believe it will result in a runtime error (don't know what it would be). I'll run it after this post and see. Tony

Interesting, the base type of the Double is a System.ValueType, and it's base type is System.Object. Yes, I am surprised. Thanks for the puzzle.
