  • Preferences bundle -- iPhone vs. Simulator

    - by trevrosen
    I have a preferences bundle that exhibits different behavior in the simulator vs the phone. The basic problem is that the default values of my preferences are getting read fine on the simulator but are coming up NULL on the iPhone. Is there some kind of special initialization I have to do for the device in order for these to be seen there? Thanks in advance for any insights!

  • Override mime type with VS Web Dev Server

    - by Douglas
    I would like to serve xbaps from the VS web dev server (cassini) to Firefox, but when served from the dev server, Firefox offers to download this file. As far as I can tell, this is because the dev server is serving the xbap file with a mime type of "application/octet-stream" instead of "application/x-ms-xbap", which works when served from IIS. Does anyone know how to change the mime type which the dev server uses for *.xbap files?

  • += new EventHandler(Method) vs += Method

    - by mafutrct
    There are two basic ways to subscribe to an event: SomeEvent += new EventHandler<ArgType> (MyHandlerMethod); SomeEvent += MyHandlerMethod; What is the difference, and when should I chose one over the other? Edit: If it is the same, then why does VS default to the long version, cluttering the code? That makes no sense at all to me.

  • Definition of SNMP Gauge32 vs Counter32

    - by DougN
    Can someone point me to a good definition of Gauge32 vs Counter32? I understand that Counter32 can wrap, but Gauge32 can't. I'm trying to understand their semantics. For example, I've heard you should take the difference between two Counter32 readings to get a value/second. Is there something like that for a Gauge32 value? Thanks for any insight.

  • A good free BON diagram generator?

    - by Audel
    Hello I need to create a static BON diagram which represents a set of clusters, classes and their relationships(inheritance and client-supplier). Does anyone know a good diagram generator I can get for free? The BON diagram is similar to the C sharp's class diagram but this one is generated by Eiffel studio =/ any diagram generators recommendations are welcome ;D Thanks in advance .

  • Do you gain any operations when you constrain a generic type using where T : struct?

    - by Fiona Holder
    This may be a bit of an abstract question, so apologies in advance. I am looking into generics in .NET, and was wondering about the where T : struct constraint. I understand that this allows you to restrict the type used to be a value type. My question is, without any type constraint, you can do a limited number of operations on T. Do you gain the ability to use any additional operations when you specify where T : struct, or is the only value in restricting the types you can pass in?

  • LINQ Query vs Lambda Expression

    - by FosterZ
    What is the difference between the following two snippets (i.e LINQ Query vs Lambda Expression) LINQ Query public Product GetProduct(int productID) { AdventureWorksDBDataContext db = new AdventureWorksDBDataContext(); Product product = (from p in db.Products where p.ProductID == productID select p).Single(); return product; } Using a Lambda expression public Product GetProduct(int productID) { AdventureWorksDBDataContext db = new AdventureWorksDBDataContext(); Product product = db.Products.Single(p = p.ProductID == productID); return product; }

  • Javascript new object (function ) vs inline invocation

    - by Sheldon Ross
    Is there any considerations to determine which is better practice for creating an object with private members? var object = new function () { var private = "private variable"; return { method : function () { ..dosomething with private; } } } VS var object = function () { ... }(); Basically what is the difference between using NEW here, and just invoking the function immediately after we define it?

  • Python singleton pattern

    - by Javier Garcia
    Hi, someone can tell me why this is incorrect as a singleton pattern: class preSingleton(object): def __call__(self): return self singleton = preSingleton() a = singleton() b = singleton() print a==b a.var_in_a = 100 b.var_in_b = 'hello' print a.var_in_b print b.var_in_a Edit: The above code prints: True hello 100 thank you very much

  • Managed code (C#) vs Matlabs and C++ for speed

    - by dotnetdev
    Hi, I am about to start developing an edge detection system (once I've read through a couple of books, which I'm doing so at good speed), but one thing I am wondering is the speed of an app like Matlabs (which can compile code to C++) vs AFORGE.NET for edge detecton. Is unmanaged code generally faster? Thanks

  • ByRef vs ByVal generates errors!?

    - by serhio
    ByRef vs ByVal generates errors!? I had a method that used an Object Function Foo(ByRef bar as CustomObject) as Boolean this method generated errors, because some strange .NET Runtime things changed the bar object, causing its Dispose()al. A lot of time spent to understand the thing(where the ... object is changed), until somebody replaced ByRef by ByVal and object wasn't change anymore when passing to this method... Somebody could explain this, what happens?
