Hi Guys, I am new To .NET Programming, Can anyone please explain me about object instantiation with the real time example ? Thanks In Advance

New object(); // instantiation object o; //declaration o = new object(); // assignment and instantiation object p = new object(); //all three See Example 2 here: http://en.wikipedia.org/wiki/Class to the same object; for example: object....
Hi, I have the following problem using template instantiation [*]. file foo.h class Foo { public: template <typename F> void func(F f) private: int member_; }; file foo.cc template <typename F> Foo::func(F f) { f(member_); } file caller.cc...

Instantiation is something that happens at compile time by using explicit instantiation in the template's implementation file, which will cause the compiler existing instantiation practices....
Are you including foo.cc into caller.cc.
Is there a way that I can insert values into a VB.NET Dictionary when I create it? I can, but don't want to, do dict.Add(int, "string") for each item. Basically, I want to do "How to insert values into C# Dictionary on instantiation?" with VB.NET. var...

It might look something like this: Public Class IntializableDictionary Inherits Dictionary... .
If you need to do this frequently you could just inherit from the Dictionary class and implement it yourself .
I do not believe this is currently possible in VB.Net .

I hope I'm wording my question properly, but what I'm trying to do is actually rather trivial. I have a bunch of code with static object instantiation that looks like this: Foo *aFoo1 = [[[Foo alloc] init] autorelease]; [anArray addObject:aFoo1]; Foo ...

You'd probably want to use two files: // Extra.h // new file with descriptive header NSArray* setupMyArray( .. .
My thought are to put the setup in a C function .
For quick tasks where I only use an instantiated object once, I am aware that I can do the following: int FooBarResult = (new Foo()).Bar(); I say this is perfectly acceptable with non-disposable objects and more readable than the alternative: Foo MyOnceUsedFoo...

The generated random numbers will be far from uniform.
Side note regarding random numbers: In fact, no, your specific example ( new Random().Next(0,100) ) is completely unacceptable .
Hi all, I'm a C programmer trying to understand C++. Many tutorials demonstrate object instantiation using a snippet such as: Dog* sparky = new Dog(); which implies that later on you'll do: delete sparky; which makes sense. Now, in the case when dynamic...

Many tutorials demonstrate object instantiation.
Reference counting to implement shared ownership.
Hi guys, After few weeks brake (had to finish couple of assignments for my study, by the way, why God allowed anyone to invent Java?), I'm trying to expand and extend my knowlege of templates with book: Templates - The Complete Guide by David Vandevoorde...

(For instance, libstdc++ contains the explicit instantiation of std::basic_string<char,char_traits<.
instantiation lets you create an instantiation of a templated class or function without actually using.
I am in need of some help here about doing a dynamic instantiation in C#. What I want to accomplish is to be able to use a string variable that is used as the name in the instantiation. I think you can use reflection or something, but I am lost on this...

If you already have a class called Averages,....
Activator.CreateInstance("MyAssembly", "MyType"); However I'm not entirely clear on what you're trying to do .
You can instantiate a class dynamically using Reflection, with Activator.CreateInstance .
I am asking this Question due to a suggestion that the way Google Chrome instantiates new process would encourage Linux adoption; because forking a process is inherently faster than the method Windows uses. Whether or not this gives any perceived speed...

You missed an important one in there: Is it noticeable? If windows take a few million more cycles to start a process, no one will notice .
Hi, Since there is the Double-checked locking issue so we have to use synchronization to guarantee the concurrent access to the following method (org.apache.struts.util.MessageResources class) : LAZY INSTANTIATION public synchronized static MessageResources...

Subsequent calls to the synchronized lazy-init factory method will be pretty much as fast as would calls to an unsynchronized eager-init method .
The overhead incurred by synchronized methods on a modern JVM is so small as to become insignificant .
