5,301,148 | 5,301,149 | why constructors aren't explicit by default? | <p>It's so easy to forget to mark a constructor "explicit": adding/removing args, making them optional etc. the single reliable way I know is to declare every constructor as explicit and then remove this keyword only if implicitness is required by design (thanks to the standard that allows this not only on single-argument constructors). But this would look ugly.</p>
<p>not intended implicit constructors open usage of (mistaken) implicit conversion, e.g. as <a href="http://en.allexperts.com/q/C-1040/2010/2/C-Implicit-Conversion.htm" rel="nofollow">here</a>. this can happen by accident, or can break backward compatibility</p>
<p>so why "explicit" is not default characteristic of a constructor if this would lead to fewer bugs?</p>
<p>p.s. yeah, I read Stroustrup's "The Design and Evolution of C++", just don't remember if he says anything about "explicit" there</p>

ViewControllerA
ViewControllerB
ViewControllerC
ViewControllerD
ViewControllerE

<p>Each ViewController is linked to a class bearing the same name.</p>
<p>As you can see from the diagram above, in Interface Builder I've got a Tab Bar Controller inside which there are lots of View Controllers. In applicationDidFinishLaunching I have written some (clearly wrong!) code with the purpose of only displaying controller A and B within the Tab Controller at launch. However the program crashes immediately with the following error message: </p>

<p>If in <code>applicationDidFinishLaunching</code> I omit the first 4 lines of code (i.e., I don't try to load ONLY ViewControllerA and ViewControllerB) the program launches perfectly, but with ALL the ViewControllers.</p>
<p>Any idea on what I am doing wrong? Thanks!</p>

<p>Basically I'm obtaining the unique name from the database itself, after an INSERT INTO, with mysql_insert_id.

4,846,566 | 4,846,567 | iPhone UITableView trigger a parent method? | <p>Okay, so I'm working on an iPhone app with a preferences-esque section where there's a base TableView, which has one section, and several rows of customized cells to hold a name and a value label. Clicking on a row brings up another View, which allows the user to pick from a list (another TableView), and select an item.</p>
<p>All of these TableViews are done programatically. The base TableView has a property that holds a Controller instance for each of the "pick from the list" Views. Each of the "pick from the list" views has a property called <code>chosenValue</code> that has the currently-selected option. I've gotten the UI to handle the <code>didSelectRowAtIndexPath</code> to update the <code>chosenValue</code> property and then "<code>pop</code>" the view (going back to the main TableView). But, even though the main TableView's <code>cellForRowAtIndexPath</code> method references the <code>chosenValue</code> property of the subview that's held in a property, the view doesn't update when an item is selected. In short, how can the sub-view trigger a <code>reloadData</code> on the parent object, after it "pops" and unloads?</p>

<p>to send messages, and it works great on the emulator and on my N1. I got complaints from users with HTC incredible that they get force close from android.mms application when they use it. I did more digging and I see there are many ways for sending messages. For example</p>

if payload_index <> 3:

1,214,489 | 1,214,490 | Javascript Namespace Help | <p>I have a pretty big Javascript script with loads of global variables & functions in it. Then a piece of code that calls one function from this js file: myfunc();</p>
<p>Ok, now I have cloned this script and modified some functionality, all function prototypes and variables are named the same in both scripts. So now I have two scripts loaded and one call to myfunc(), now we have a clash because there are loads of global variables with the same names and two myfunc()s.</p>
<p>What I want to do is wrap this cloned script in a namespace, so that I can modify the original call to: clone.myfunc() which will call the new function, but I also want myfunc() to just refer to the original script. In other words I can't touch the original script (no permissions) and I want to be able to use both the clone and the original at runtime.</p>
<p>This is the script im cloning: <a href="http://pastebin.com/6KR5T3Ah" rel="nofollow">http://pastebin.com/6KR5T3Ah</a></p>
<p>Javascript namespaces seem quite tricky this seems a nice namespace method:</p>
<pre><code>var namespace = {
foo: function() {
}
bar: function() {
}
}
...
namespace.foo();
}
</code></pre>
<p>However that requires using an object, and the script (as posted above) is humongous at nearly 4000 lines, too much to objectize I think?</p>
<p>Anyone know a better solution to avoid namespace pollution, with one script I cant touch and one being a clone of that script. Just so I can call myfunc() and clone.myfunc() and all global variables will behave in their respected scope.</p>
<p>It's either that, or I go through and modify everything to have unique names, which may take a lifetime</p>
<p>This is a Mozilla addon if it helps context wise.</p>
<p>Thanks.</p>

</blockquote>
<p>I have a class hierarchy where each derived class overrides a given virtual function and starts its implementation by calling the one in its parent class. The goal is to have each of the derived implementation to be executed, but I do not like the way I do it.</p>
<p>For example, I have this class:</p>
<pre><code>class base
{
public:
void do_stuff() { do_something(); }
virtual void do_something() { }
};
</code></pre>
<p>Then I derive this class on several levels:</p>
<pre><code>class derived_10:
public derived_9 // which inherit from derived_8 and so on until derived_0
// which inherit from base
{
public:
virtual void do_something()
{
// this will also call derived_8::do_something() and so on
// until base::do_something()
derived_9::do_something();
// then, some stuff
}
};
</code></pre>
<p>I'm looking for a solution that will make sure that all derived_x::do_something() will be called in sequence when base::do_stuff() is called, without having to expect the derived classes to do this themselves. Do you have an idea of the best way to get this behavior ?</p>
