4,855,126 | 4,855,127 | Constant value calculation | <p>I have an hpp file with following code:</p>
<pre><code>const float PixelsPerMeter = ConfigManager->Get<float>("koef", 100.0f);
inline const float Meters2Pixels(float meters) { return meters * PixelsPerMeter; }
inline const float Pixels2Meters(float pixels) { return pixels / PixelsPerMeter; }
const float ScreenArea = Pixels2Meters(ScreenSizeX) * Pixels2Meters(ScreenSizeY);
</code></pre>
<p>It worked before, but now <code>ScreenArea</code> = <code>inf</code> somehow. I use it from static function. I put a breakpoint in that function and print out the value of <code>PixelsPerMeter</code>(100.0), <code>ScreenSizeX</code> and <code>ScreenSizeY</code>. Everything is okay, but <code>ScreenArea</code> is calculated wrong.</p>
<p>When I write directly <code>Pixels2Meters(ScreenSizeX) * Pixels2Meters(ScreenSizeY)</code> instead of using <code>ScreenArea</code> constant everything works.</p>
<p>How it could be?</p>

1,696,063 | 1,696,064 | How to associate each item in ListView with id from database | <p>I have a <code>ListView</code> object with <code>Adapter</code> extended from <code>CursorAdapter</code>.

I need to query my database with <code>_id</code> for currently chosen list's <code>item</code>.

5,603,640 | 5,603,641 | possible to extract functions from a javascript file? | <p>Not sure if this is the right approach of if this even a "good" question, but I'm loading a javscript as part of a plugin style architecture and I have the following problem:</p>
<p>If a particular node has a reference to a plugin, I want to load that plugin per the url provided via the json description of that plugin. the description will have something like the following (or a functional equivalent):</p>
<pre><code>{
"pluginSrc" : "http://mysite.com/plugins/1204.js",
"configData" :
{
"someData", "someValue",
"someMoreData", "etc"
}
}
</code></pre>
<p>When the javascript loads, I'll have an onload handler that will check to see if a function name exists on the window object and if so, create a new instance of that function and pass it the config data (more or less), this part works very well, with a few exceptions.</p>
<p>Sometimes I do not have a reference to the name of the function that I need to invoke and there is no way to get it from the json. What would be ideal, is if I could tell which function was added to the window object on the script's onload callback and create an instance of that function. Is this possible? I only need to worry about modern browsers, particularly webkit. Apologies if the question isn't clear, I'd be happy to clarify, but producing a fiddle might be difficult as there's a lot of code to write to reach a minimal example.</p>
<p>What I'm thinking about so far is to create some kind of global variable in the loaded script file like</p>
<pre><code>function MediaAnalytics(){};
var LoadedClass = MediaAnalytics;
</code></pre>
<p>and just creating an instance of LoadedClass when the script is loaded, but this falls short of a panacea because I will not always be writing the plugin.</p>
<p>EDIT: These scripts will most likely not be from the same domain.</p>

483,487 | 483,488 | Loading user controls dynamically | <p>I have an aspx page and therein I have a dropdown control. Depending on the selected value, I need to load the user control that many times in the page. E.g..if first item is selected, I need to query DB and get how many subsections are their for this value and then load the user control that many times. It is working fine if I load the user controls in Page Load. However, If I want the view state to persist in these dynamically added user controls, I need to load them before load in Page_init event. However, when I try to do this in Page_Init, the viewstate for the dropdown has not been restored and I dont know how many usercontrols to load.</p>
<p>Any suggestions?.</p>

4,194,190 | 4,194,191 | Abstract getter with concrete setter in C# | <p>I'm trying to write an abstract base class for read-only collections which implement <code>IList</code>. Such a base class should implement the set-indexer to throw a <code>NotSupportedException</code>, but leave the get-indexer as abstract. Does C# allow such a situation? Here's what I have so far:</p>
<pre><code>public abstract class ReadOnlyList : IList {
public bool IsReadOnly { get { return true; } }
public object this[int index] {
get {
// there is nothing to put here! Ideally it would be left abstract.
throw new NotImplementedException();
}
set {
throw new NotSupportedException("The collection is read-only.");
}
}
// other members of IList ...
}
</code></pre>
<p>Ideally <code>ReadOnlyList</code> would be able to implement the setter but leave the getter abstract. Is there any syntax which allows this?</p>

<p>I am scraping a site, and it will scrape two address boxes - each of which may have minor differences.</p>
<p>One of the addresses is like this:</p>
<pre><code>ONE MICROSOFT WAY
REDMOND WA 98052-6399
425-882-8080
</code></pre>
<p>And the other is like this:</p>
<pre><code>ONE MICROSOFT WAY
REDMOND WA 98052-6399
</code></pre>
<p>I save the entire string for both (there's HTML tags around them in the original but I didn't think it was necessary to illustrate my point), and then separate based on those HTML tags. This means it processes each newline (i.e. ONE MICROSOFT WAY) as a separate variable.</p>
<p>What I want to do is to see if there are duplicates between the addresses, the problem is that they're separate values in the first array, and then in the internal array (I'm not sure the terms for PHP, so bare with me), it is separating each of the two addresses line by line.</p>
<p>So basically, is there a way to check for duplicate values?</p>
<p>Here is sample data:</p>
<pre><code><div class="mailer">
Mailing Address
<span class="mailerAddress">ONE MICROSOFT WAY</span>

User <code>reventlov</code> declares</p>
<blockquote>
<p>The biggest problem I have with C++ is that it's waaay too easy to think that you're a "C++ programmer" without really understanding all the things you need to understand to use C++ acceptably well.</p>
<p>You've got to know RAII, and know to use namespaces, and understand proper exception handling (for example, you should be able to explain why the pop() methods in the STL do not return the values they remove). You've got to know which of the three generations of functions in the standard library is the right one. You should be familiar with concepts like PIMPL. You need to understand how the design of the standard library (especially the STL) works. You need to understand how macros interact with namespaces, and why you usually shouldn't use macros in C++, and what you should use instead (usually templates or inlines, rarely a class). You need to know about boost.</p>
</blockquote>
<p>I think I'm one of those clueless C++ programmers he mentions. To keep this brief, my questions are</p>
<ol>
<li>Can you give an example of a typical RAII oversight mistake, e.g. where best practices dictate the use of RAII but programmers have implemented using some other way?</li>
<li><em>Why</em> doesn't the pop() methods in STL return the value they remove? </li>
<li>I read the Wikipedia entry for PIMPL, didn't understand any of it. Can you give an example of a typical usage of the PIMPL idiom.</li>
