There is also [a list for Visual C++ 2010][1] (that article describes the core language features that have been implemented; the PDF linked from the article describes the library features that have been implemented).

**Edit:** I&#39;ve just come across an awesome list:  the Apache C++ Standard Library wiki has [**a table listing the C++11 core language features**][2] and which C++ compilers support each of them.

  [2]: http://wiki.apache.org/stdcxx/C++0xCompilerSupport

Here is the best list IMO since it breaks it down into several tabs like core language, library, etc:
[Summary of C++0x Feature Availability in gcc and MSVC][1]

Google Map API v3 ~ Simply Close an infowindow?

I&#39;m working on a iPhone app which has a pretty large UITableView with data taken from the web, so I&#39;m trying to optimize its creation and usage.


I found out that `dequeueReusableCellWithIdentifier` is pretty useful, but after seeing many source codes using this, I&#39;m wondering if the usage I make of this function is the good one.

Here is what people usually do:

    UITableViewCell* cell = [tableView dequeueReusableCellWithIdentifier:@&quot;Cell&quot;];
   
    if (cell == nil) {
      cell = [[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:@&quot;Cell&quot;];
    
    // Add elements to the cell
    return cell;

And here is the way I did it:

    // The cell row
    NSString identifier = [NSString stringWithFormat:@&quot;Cell %d&quot;, indexPath.row]; 
    
    UITableViewCell* cell = [tableView dequeueReusableCellWithIdentifier:identifier];

    if (cell != nil)
      return cell;

    cell = [[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:identifier];
    // Add elements to the cell
    return cell;

The difference is that people use the same identifier for every cell, so dequeuing one only avoids to alloc a new one.

For me, the point of queuing was to give each cell a unique identifier, so when the app asks for a cell it already displayed, neither allocation nor element adding have to be done.

&lt;i&gt;In fine&lt;/i&gt; I don&#39;t know which is best, the &quot;common&quot; method ceils the table&#39;s memory usage to the exact number of cells it display, whilst the method I use seems to favour speed as it keeps all calculated cells, but can cause large memory consumption (unless there&#39;s an inner limit to the queue).

Am I wrong to use it this way? Or is it just up to the developer, depending on his needs?

I read on the internet many tutorials that explained how to use lambdas with the standard library (such as `std::find`), and they all were very interesting, but I couldn&#39;t find any that explained how I can use a lambda for my own functions.

For example:

    int main()
    {
    	int test = 5;
    	LambdaTest([&amp;](int a) { test += a; });
    
    	return EXIT_SUCCESS;
    }

How should I declare `LambdaTest`? What&#39;s the type of its first argument? And then, how can I call the anonymous function passing to it - for example - &quot;10&quot; as its argument?

How to declare a function that accepts a lambda?

What of these two methods is in C more efficient? And how about:

    pow(x,3)
 vs. 

    x*x*x // etc?

What is more efficient? Using pow to square or just multiply it with itself?

I want to pass an overloaded function to the `std::for_each()` algorithm. For example,

    class A {
        void f(char c);
        void f(int i);

        void scan(const std::string&amp; s) {
            std::for_each(s.begin(), s.end(), f);
        }
    };

I&#39;d expect the compiler to resolve `f()` by the iterator type. Apparently, it (GCC 4.1.2) doesn&#39;t do it. So, how can I specify which `f()` I want?


How do I specify a pointer to an overloaded function?

I am looking for a free C++ fixed point library (Mainly for use with embedded devices, not for arbitrary precision math). Basically, the requirements are:

* No unnecessary runtime overhead: whatever can be done at compile time, should be done at compile time.
* Ability to transparently switch code between fixed and floating point, with no inherent overhead.
* Fixed point math functions. There&#39;s no much point using fixed point if you need to cast back and forth in order to take a square root.
* Small footprint.

Any suggestions?

I&#39;m trying to map a C structure to Java using JNA. I came across something that I&#39;ve never seen.

The `struct` definition is as follows:

    struct op 
    {
        unsigned op_type:9;  //---&gt; what does this mean? 
        unsigned op_opt:1; 
        unsigned op_latefree:1; 
        unsigned op_latefreed:1; 
        unsigned op_attached:1; 
        unsigned op_spare:3; 
        U8 op_flags; 
        U8 op_private;
    };

You can see some variable being defined like `unsigned op_attached:1` and I&#39;m unsure what would that mean. Would that effect the number of bytes to be allocated for this particular variable?

What does &#39;unsigned temp:3&#39; in a struct or union mean?

I am trying to use VS2010&#39;s 1-Click Publish feature to deploy a test site from my laptop to my server. I have the firewall turned off on both machines and the MS Deployment Service is up and running on both my laptop and the server.

However, when I try and publish from VS2010 on my laptop I get the following error:

&gt; Error 1 Web deployment task failed.(Remote agent (URL https://192.168.1.181/:8172/msdeploy.axd?site=LocationsTest) could not be contacted.  Make sure the remote agent service is installed and started on the target computer.)

Visual Studio 2010 Web deployment task failed

We have several external DLL files being referenced in our Web Application Project. We have a deployment project for installing on the hosting servers. When we were using .NET 3.5 and Visual&amp;nbsp;Studio&amp;nbsp;2008 the DLL files were being copied to the bin folder. Since we have upgraded to .NET 4 and Visual&amp;nbsp;Studio&amp;nbsp;2010 this no longer happens, and we are getting server errors since the references cannot be found.

CopyLocal is set to true, and I cannot find anything inside the web.config which suggests this is being set elsewhere.

I&#39;ve gotten accustomed to many of the Java IDEs ([Eclipse][1], [NetBeans][2], and [IntelliJ IDEA][3]) providing you with a command to generate a default constructor for a class based on the fields in the class.

For example:

    public class Example
    {
        public decimal MyNumber { get; set; }
        public string Description { get; set; }
        public int SomeInteger { get; set; }

        // ↓↓↓ This is what I want generated ↓↓↓
        public Example(decimal myNumber, string description, int someInteger)
        {
            MyNumber = myNumber;
            Description = description;
            SomeInteger = someInteger;
        }
    }

Having a constructor populate all of the fields of an object is such a common task in most OOP languages, I&#39;m assuming that there is a some way for me to save time writing this boilerplate code in C#. I&#39;m new to the C# world, so I&#39;m wondering if I&#39;m missing something fundamental about the language? Is there some option in Visual Studio that is obvious?

Microsoft&#39;s C++ compiler and linker seem to have an odd relationship with `mspdb100.dll`. When run from the IDE, of course, the compiler and linker work fine. When running either one from the command line, I get an error.

No problem, I located the DLL and copied it to the directory. Now the compiler works fine, but the linker dies.

I could solve the problem by adding &quot;%VS10%\Common7\IDE&quot; to my PATH, but for various reasons (performance, system purity, OCD, etc), I don&#39;t want to do that. Why is this setup so touchy, and is there anything else I can do to solve it?

what tokens do you find useful in visual studio?
(*visual studio 2010* → **environment** → **task list** → tokens)

currently i have only:

 - **HACK** - *low*
 - **REVIEW - high**
 - **TODO** - normal
 - **WTF - high**

(only these - deleted some default ones)

**are you using any others?**

**are you covering any other important thing with comment tokens?**

any best practices? thnx

`ListView.ScrollIntoView(object)` currently finds an object in the `ListView` and scrolls to it. If you are positioned beneath the object you are scrolling to, it scrolls the object to the top row. If you are positioned above, it scrolls it into view at the bottom row.

I&#39;d like to have the item be scrolled right into the center of my list view if it is currently not visible. Is there an easy way to accomplish this?

Is there some equivalent class for C++1x&#39;s std::unique_ptr in the boost libraries? The behavior I&#39;m looking for is being able to have an exception-safe factory function, like so...

    std::unique_ptr&lt;Base&gt; create_base()
    {
        return std::unique_ptr&lt;Base&gt;(new Derived);
    }

    void some_other_function()
    {
        std::unique_ptr&lt;Base&gt; b = create_base();

        // Do some stuff with b that may or may not throw an exception...

        // Now b is destructed automagically.
    }

EDIT: Right now, I&#39;m using this hack, which seems like the best I can get at this point...

    Base* create_base()
    {
        return new Derived;
    }

    void some_other_function()
    {
        boost::scoped_ptr&lt;Base&gt; b = create_base();

        // Do some stuff with b that may or may not throw an exception...

        // Now b is deleted automagically.
    }

I recently tried to use [Qt Creator][1] 1.3.2, Qt 4.6.2, and GCC 4.4.0 (32-bit version) on Windows 7 (64-bit) to compile an application using some of the experimental C++0x extensions and encountered the following (fatal) error:

&gt; This file requires compiler and library support for the upcoming
ISO C++ standard, C++0x. This support is currently experimental, and must be
enabled with the -std=c++0x or -std=gnu++0x compiler options.

In my search for a solution, I came across the thread *[qmake and compiler flags?][2]*, and added the following to the .pro file:

    CXXFLAGS += -std=c++0x

but that didn&#39;t seem to make a difference.

So, I expect there&#39;s some tag I need to add to the .pro (project) file, but I&#39;ve never messed with the GCC compiler switches in Qt, QMake, and QtCreator before, and I am uncertain about the proper invokation / incantation.  So, my question is how do you set GCC compiler switches when using QtCreator, QMake, and Qt?

I don&#39;t understand the last line of the example on page 148 of the FCD (&#167;7.6.1.2/4):

    const int&amp;&amp; foo();
    int i;
    struct A { double x; };
    const A* a = new A();
    decltype(foo()) x1 = i;     // type is const int&amp;&amp;
    decltype(i) x2;             // type is int
    decltype(a-&gt;x) x3;          // type is double
    decltype((a-&gt;x)) x4 = x3;   // type is const double&amp;

Why do the parentheses make a difference here? Shouldn&#39;t it simply be `double` like in the line above?
