    VS 2008 Re: Properties of sub-classes?

    It seems to me that when the user selects an attack, Fighter A (the attacker) is asked for something like an Attack object (maybe with a ChooseAttack() method?), which might just be a simple number...

    VS 2008 Re: Properties of sub-classes?

    Sort of, yes.

    I'd start by asking why you want to get _Attack(x)._Hit(y)._Texts(z)? What has determined the values of x, y and z? What are you going to do with the return? There's behaviour...

    Re: Creating traffic simulator ??

    So what you want to do is create an application that does basically what another application does. That's fine.

    So... the fact that you're asking about how to draw the traffic lights suggests you...

    VS 2008 Re: Properties of sub-classes?

    Yes, this approach would work the same, where it would need to vary is if you are using Structs instead of Classes, at which point you need to take into account the pass-by-value semantics that go...

    VS 2012 Re: Encryption

    Does the built-in method of putting a * in the version number in the AssemblyInfo not meet your needs? Are you using a build server to produce your builds?

    Okay, lots of things to address here, I'll start with this one:

    Don't multiply by 100, instead use the Percentage numeric formatter. This takes a fractional value and displays it as a percentage respecting the user's culture settings:

    If the MsgBox call is allowing your program to continue then I would hazard a guess that the code is being allowed to continue by the processing of another event on the UI thread - does this event...

  15. Re: Using a generic list to store a collection of class objects

    Since the instructions refer to "using LINQ" to load the collection, you probably don't want to ToArray the ReadAllLines, and you don't want to use a For Each loop either.

    ReadAllLines returns an...

    No, what you should do is stop storing application state in user controls.

    VS 2012 Re: problem with timer

    My guess from reading your code is that you want the following to happen:

    2) When it is 15:00, run the "Do Some...
