83,042 | 83,043 | php mktime AMPM value wrong | <p>I'm trying to get the next minute value in php by doing the following.</p>
<pre><code>$one_minute_later = mktime(date("g"), date("i")+1, date("s"), date("n"), date("j"), date("Y"));
$send_month = date("n", $one_minute_later); // Numeric representation of a month, without leading zeros
$send_day = date("j", $one_minute_later); // Day of the month without leading zeros
$send_year = date("Y", $one_minute_later);
$send_hour = date("g", $one_minute_later); // 12-hour format of an hour without leading zeros
$send_minute = date("i", $one_minute_later); // Minutes with leading zeros 00 to 59
$send_ampm = date("A", $one_minute_later);
</code></pre>
<p>However, doing so ALWAYS returns the value AM for AMPM. Any idea why? For instance, when I run this code at 6:00 PM, one minute later should return 6:01 PM. However, it's returning 6:01 AM.</p>

1,567,889 | 1,567,890 | iPhone : Wait for users to complete or dismiss view in AppDelegate | <p>I'm in the process of adding a method that changes core application settings and as a result needs to be initiated very early in the code execution, this will only be displayed during the development phases of the application.</p>
<p>I've created a view that allows the users to set / change the required settings and the 'addview' in the 'applicationdidFinishLaunchingWithOptions' method. </p>
<p>What I'm struggling with is waiting/pausing the appdelegate until the user has completed and dismissed the new view, i.e. display view and wait until the 'Done' button is pressed. Are there any ways to achieve this, the application is very complex and my new view changes values in the root.plist resulting in no code changes elsewhere in the application</p>

240,960 | 240,961 | When to use the Value keyword in C# | <p>I am using a <a href="http://weblogs.asp.net/pwelter34/archive/2006/05/03/444961.aspx" rel="nofollow">custom serializer</a> in c# in order to serialize/deserialize an object with a dictionary. However during the deserialization the dictionary object was not being set correctly. See code:</p>
<pre><code>public DictionarySerializer<String, Point> jointDictionary
{
get { return _jointDictionary; }
set { _jointDictionary = jointDictionary; }
}
</code></pre>
<p>The jointDictionary object coming back was empty however in the debugger thread I noticed a "value" object that had the contents of my dictionary. Changing my code to the following fixed my issue:</p>
<pre><code>public DictionarySerializer<String, Point> jointDictionary
{
get { return _jointDictionary; }
set { _jointDictionary = value; }
}
</code></pre>
<p>I have read about the "value" keyword and understand that it is a reserved word in C# to specify the value that the client it trying to use to set the object. So my question is, why wouldn't the jointDictionary reference work as in my first attempt? And what is the correct usage for the value keyword?</p>

<p>How does the system know when (how often) to make the onPerformSync() call in the SyncAdapter? </p>

<p>Is there an easy way in jQuery/JS of selecting the elements that "intersect" from the following HTML?</p>
<pre><code><div id="first">
<div id="source-AAA"/>
<div id="source-CCC"/>
<div id="source-EEE"/>
<div id="source-FFF"/>
</div>
<div id="second">
<div id="BBB"/>
<div id="CCC"/>
<div id="DDD"/>
<div id="FFF"/>
</div>
</code></pre>
<p>i.e. getting hold of the elements <code>#CCC</code> and <code>#FFF</code> from <code>div#second</code>, based on the fact that these two IDs are in <code>#first</code>?</p>
<p>I guess the proper answer is to do the intersect on the server-side (which is possible, but painful, as the two data sets come from different components), but I thought I'd check in case anyone knows of a neat way to do it in jQuery?</p>

4,041,473 | 4,041,474 | slideDown behaviour on hover with inner divs being absolute | <p>Here is something that I can't figure it out.</p>
<p>Here is a simple example: <a href="http://jsfiddle.net/MrkMZ/" rel="nofollow">http://jsfiddle.net/MrkMZ/</a></p>
<p>HTML:</p>
<pre><code><div id="box">
<div id="top"><a href="#">top text</a></div>
<div id="bottom"><a href="#">bottom text</a></div>
</div>
</code></pre>
<p>CSS:</p>
<pre><code>#box {
width: 200px;
height: 200px;
background-color: yellow;
position: relative;
}
#top {
position: absolute;
top: 0;
left: 0;
width: 200px;
height: 50px;
background-color: #ff0000;
}
#top a {
margin-top: 20px;
display: inline-block;
}
#bottom {
position: absolute;
bottom: 0;
left: 0;
width: 200px;
height: 30px;
background-color: #ff0000;
}
</code></pre>
<p>JS:</p>
<pre><code>$('#box').hover(
function(){
$(this).find('#top, #bottom').slideUp(300);
},
function(){
$(this).find('#top, #bottom').slideDown(300);
}
);
</code></pre>
<p>As you can see, on box hover the top and bottom divs slide correctly but the text inside the top and bottom divs behave differently when sliding. The top text stays while the bottom text slides down with the div.</p>
<p>Anyway to make even the top text slide? Or make the bottom text stay instead of sliding.</p>
<p>On slideDown/slideUp jQuery changes the height of the element.</p>
<p>The only difference is that one has top: 0 and bottom one has bottom: 0. That alone makes this weird effect.</p>
<p>What am I missing here?</p>

<p>The obvious answer is to simply copy all of the code and markup files into the new project, make the aforementioned tweaks, and consider the job done. However I'm not keen on this at all due to the amount of duplicated code it will create.</p>
<p>My next idea was to move the code for the pages (i.e. the code-behind file) into a separate assembly which can then be referenced from both sites. This is a little awkward however as if you don't take the designer file with it, you get a lot of build errors relating to missing controls. I don't think moving the designer file is a good idea though as this will need to be regenerated each time the markup is altered.</p>
<p>Does anyone have any suggestions for a clean solution to this problem?</p>

1,888,554 | 1,888,555 | Hiding a class from outside when use is only for inside an API in C++ | <p>In languages like Java, you can declare a class without a modifier so it will only be visible inside the same package. I need to do something similar in C++. I am trying to create an API that will be a library to be used in other applications. After asking <a href="http://programmers.stackexchange.com/questions/132403/should-i-use-friend-classes-in-c-to-allow-access-to-hidden-members">this</a> question on programmers Stackexchange, I have decided to use some sort of handle, which will just be an unsigned integer that is passed to an API function, which will then pass it to a class that will look it up in some sort of table and return a pointer to the object the handle represents, back to the function. The API function will then be allowed to operate on the pointer, but without the public ever having access to the pointer. </p>
<p>The problem is, I would like the class that handles the handles to not be visible to the public (even though the public won't have an instance of the class that contains the handles), as it is only needed inside the API functions. Also, I wanted this handle class to be a template (only needed for compiling the API), because I would most likely have handles representing different types of classes (although I could probably get away with one table containing void pointers, but it seems a little unsafe). I cant hide the class in a .cpp file, because it would be needed in multiple .cpp files that compose the API.</p>
<p>Also, I was thinking about using the pimpl idiom in any classes that have public functions, that way if there were any private functions in them that needed a parameter related to one of my classes hidden from the public, a header file including hidden classes would not need to be included with the API libraries for the API user to be able to compile the program.</p>
<p>So what would be the best way to hide classes that are only needed among other classes (spread across multiple .h and .cpp files) inside the API its self, from the outside world?</p>

417,770 | 417,771 | Memory leakage on event handling | <p>I've been reading about memory leakages lately and haven't yet wrapped my head around all of it and have some questions regarding my own style of writing. Specifically, I'm not really sure if the way I handle events might be a source of leaking. Consider the following code </p>
<pre><code>function Wrapper(text) {
this.text = text;
this.bindHandlers();
};
Wrapper.prototype.onClick = function (e) {
alert(this.text);
};
Wrapper.prototype.bindHandlers = function () {
var t = this, div = $('<div>' + this.text + '</div>');
var reallyHugeArray = [1,2,3...]; // an array of 100000 elements for example
div.click(function (e) {
// all variables of the parent function are in scope for this function, including reallyHugeArray
t.onClick(e);
});
$(document).append(div);
};
var a = new Wrapper('testString');
// had enough fun with the Wrapper, now let's nullify it
a = null;
</code></pre>
<p>As you can see, I like to use an anonymous functions as the event handler so that it would be more convenient to have access to instance specific variables (in this case <code>this.text</code> in the <code>onClick</code> function) and functions. However, if I understood correctly, having an anonymous function inside a function (as is the event handler), which has access to the local scope, disables the garbage collector from removing the local variables, therefore creating a leak. </p>
<p>So my question is whether this method of event handling can create memory leakages and if it does, is there any way to prevent it, but still have a similarily convenient way to access the instance variables and functions?</p>
<p>(Off-topic: a function inside a function inside a function makes Javascript sound like Inception)</p>

<p>I have tried to start from the main class but this seems to be getting me nowhere because I keep being sent to a dozen different classes.</p>
<p>What I wanted to ask is if there is a software that shows what pieces of code are running during the time the game is turned on.</p>
<p>If such software doesn't exist, where in the code do you guys recommend me to start and what tips can you give me to make this go well?</p>

2,108,831 | 2,108,832 | ASP.NET Forms Parameters on Links | <p>Ok, let me start this with I am more of an MVC person. I have a result set that I am trying to add paging. All I really want is a previous and next button on my page which are Link controls. I need these controls to post back to the same page, but have a query parm like page=4. How do I add these links? I see the PostBackUrl property on the link. Should I just use Request.Url and stuff it into PostBackUrl? Then I have to do string searches on the parm... it gets nasty. Is that the only way? I have tried ViewState, please dont suggest that... it is unpredictable garbage as far as I am concerned.</p>
