I am still new to C# and I've been struggling with various issues on arrays. I've got an array of metadata objects (name value pairs) and I would like to know how to create only the number of "InputProperty" objects that I truly need. In this loop I've arbitrarily set the number of elements to 20 and I try to bail out when the entry beco...
I'm learning Objective-C through Cocoa (And loving it). I'm following a tutorial. Theres a class called Menu and the interface looks something like this. @interface Menu: MenuObject {} @end @interface MenuLayer : LayerObject {} -(void) someMethod:(id)sender -(void) someOtherMethod:(id)sender @end and the implementations follow the s...

As the title points out, I'm relatively new at XNA. However, I've been given a trivial assignment by my boss to see if I can get it done. I have no doubt that I eventually will, but some pointers in the right direction would help. This isn't a homework assignment, and I'm just looking for a couple of tips and pointers so I don't have to...

I want to learn how others cope with the following scenario. This is not homework or an assignment of any kind. The example classes have been created to better illustrate my question however it does reflect a real life scenario which we would like feedback on. We retrieve all data from the database and place it into an object. A object...
say I have a class: class A { public: A() {} }; and a function: void x(const A & s) {} and I do: x(A()); could someone please explain to me the rules regarding passing temporary objects by reference? In terms of what the compiler allows, where you need const, if an implicit copy happens, etc. From playing around, it seems like...

Given Linq and technologies like i4o is there any real reason why an object oriented database management system won't be a viable alternative to a relational database management system for new projects starting in the next 3 to 5 years? ...
I have a Perl project were I just had a problem by making a circular package call. The code below demonstrates the problem. When this is executed, each package will call the other until all of the memory of the computer is consumed and it locks up. I agree that this is a bad design and that circular calls like this should not be mad...
I'm a bit confused with JavaScript's delete operator. Take the following piece of code: var obj = { helloText: "Hello World!" }; var foo = obj; delete obj; After this piece of code has been executed, obj is null, but foo still refers to an object exactly like obj. I'm guessing this object is the same object that foo pointed to. ...

I'm using a PHP class someone wrote to interface with the BaseCamp API. The particular call I'm doing is to retrieve the items in a todo list, which works fine. My problem is, I'm not sure how to access just the todo-items property of the object that is returned. Here's the var_dump of the returned object: object(stdClass)[6] public...

Suppose I have two instances of the same class. The class has a pointer to some data, and I want the instances to exchange the pointers as part of some private function's algorithm, but without compromising the data to everybody else by giving a direct access to it through a public function. My first idea was to add a static variable o...
Hello, Imagine we have 5 string variables and we want to assign "Foo" to them during runtime. Instead of this string a1 = "Foo"; string a2 = "Foo"; string a3 = "Foo"; string a4 = "Foo"; string a5 = "Foo"; Can't we use something like this: for(int i = 0;i < 5;i++) { a+i = "Foo"; } Is it impossible to access them in a similiar ...
