<p>Does such a thing exist? or could anyone please recommend how I could implement such a container?</p>
<p>basically I have a std::map which uses a 64bit integer as its key and a custom datatype as the containing item.</p>
<p>I need to be able to periodically remove items that havent been accessed in a while in the most optimal way. does anyone have any suggestions for this?</p>

Grab another window by handle and show it as a preview/video in my form (C#)

<p>So basically I am trying to capture the output of a render window that is hidden by default to put into a controller application as a preview. I've been told by some people in my line of work that this is possible by grabbing the window handle and somehow putting that as a video on your existing form.

What is an easy way to create a trivial one-off Python object?
|
<p>I would like to create a trivial one-off Python object to hold some command-line options. I would like to do something like this:</p>
<pre><code>options = ??????
options.VERBOSE = True
options.IGNORE_WARNINGS = False
# Then, elsewhere in the code...
if options.VERBOSE:
...
</code></pre>
<p>Of course I could use a dictionary, but <code>options.VERBOSE</code> is more readable and easier to type than <code>options['VERBOSE']</code>.</p>
<p>I <em>thought</em> that I should be able to do</p>
<pre><code>options = object()
</code></pre>
<p>, since <code>object</code> is the base type of all class objects and therefore should be something like a class with no attributes. But it doesn't work, because an object created using <code>object()</code> doesn't have a <code>__dict__</code> member, and so one cannot add attributes to it:</p>
<pre><code>options.VERBOSE = True
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'object' object has no attribute 'VERBOSE'
</code></pre>
<p>What is the simplest "pythonic" way to create an object that can be used this way, preferably without having to create an extra helper class?</p>

Sensor power/notification rate issues
|
<p>I'm writing an app that extends the SensorEventListener interface to listen for changes to the barometer, which I log in a logfile. Before I start logging, I prepend a system time in milliseconds (let's call this Millisecond Timestamp 1, or MT1), and after the logging is finished, I append another system timestamp in milliseconds (let's call this Millisecond Timestamp 2, or MT2).</p>
<p>The SensorEvent has its own timestamp (which I will call Nanosecond Timestamps, or NT), which I also log, between MT1 and MT2.</p>
<p>The problem is this: If the phone goes to sleep during the logging, the SensorEvent rate seems to no longer occur at the rate which I set (for example, SENSOR_DELAY_FASTEST). Furthermore, even though the SensorEvent timestamp is supposed to represent the nanoseconds of uptime since the phone has been rebooted, there are "missing" nanoseconds--the time gap between MT2 and MT1 is often twice or more that between NTN (where N is the number of samples) and NT1.</p>
<p>I've been able to sort of resolve this issue by using PowerManager.Wakelock(), but that results in my app being a huge power hog and seems like a really clumsy hack. Is there any other way to work around this problem?</p>

Make a looping infinite scroll
|
<p>I am trying to make a scrollable <code><div></code> to contain a variable amount of items (2-20) that loop. I'd like to give it the appearance of a wheel, as in the iOS wheel selector <img src="http://i.stack.imgur.com/gZofr.jpg" alt="enter image description here"></p>
<p>I've searched about infinite scroll with jQuery but I only get results of the famous twitter and facebook functionality when it loads more content as you get closer to the bottom of the page. What I want is to replicate the items on the edges of the div, so that if you get closer to the bottom, items from the beggining would appear continually, without just appending more (it would get too big).</p>
<p>I am thinking about a way of doing this myself, without messing with the scroll when appending items at the beggining, but I'm sure there must be a plugin for this already.</p>

<p>I am trying to center a div horizontally to a marker as you can see here <a href="http://jsfiddle.net/rKejG/8/" rel="nofollow">http://jsfiddle.net/rKejG/8/</a>, however it's a little more to the right than it should be.</p>

marginLeft: (parseInt($("#content").width(), 10) / 2) - (parseInt($("#infobox").width(), 10) / 2) + 'px'
});
</code></pre>
<p>Then I realized that I should probably add the halves of <code>content</code> and <code>infobox</code> and put them in a negative margin, but that made it a whole lot worse:</p>
<pre><code>$("#infobox").css({
marginLeft: '-' + (parseInt($("#content").width(), 10) / 2) + (parseInt($("#infobox").width(), 10) / 2) + 'px'

Why does my code ignore a true if-condition?
|
<p>I've got the following code:</p>
<pre><code> private static void checkCodesInPlayerCenter(GameObject player)
{
Vector2 collisionCenter = player.GetCollisionCenter(player.PublicCollisionRectangle);
if (TileMap.GetMapSquareAtPixel(collisionCenter) == null)
{
return;
}
for (int i = 0; i < TileMap.GetMapSquareAtPixel(collisionCenter).Codes.Count; ++i )
</code></pre>
<p>It is possible that sometimes the object I get from GetMapSquareAtPixel is null. To not cause a NullReferenceException in the for-loop I decided to check is its null, and if so end the function early, however it seems to completely ignore the if-condition, even if the object returned is null.
I've set a breakpoint on the return statement but the code never goes there and instead triggers the NullReferenceException I tried to avoid.</p>
<p>Any help please? </p>

How to split a deliminated string with encapsulation and escapes
|
<p>I would like to split a string deliminated by a character such as ‘&’, but in the case where some values contain the deliminator I would like to escape with double quotes. What is an elegant approach to splitting while ignoring the deliminating characters that have been escaped while also accounting for escape character escapes? </p>
<p>For example split this string properly</p>
<pre><code>var1=asdfasdf&var2=contain””quote&var3=”contain&delim”&var4=”contain””both&”
</code></pre>
<p>Into:</p>
<pre><code>var1=asdfasdf
var2=contain"quote
var3=contain&delim
var4=contain"both&
</code></pre>
<p>Incidentally, I am thinking Regex...</p>

jQuery slider with hover navigation and pause - not using plugin
|
<p>In my later days of writing jQuery as raw as possible, and not having loads of jQuery plugins stacking up and slowing my page down - I'm trying to create my own slider.</p>
<p>I have created a fiddle of how far I have got so far.</p>
<p>My HTML markup is not dynamic - and the slide animate process is positional only.</p>
<p><br /></p>
<p>The complications I'm having is the animations have to fully run before the next animation can begin which makes my animations begin to queue up if you hover the menu lots.</p>
<p>I need an animation to stop half way though if the hover changes, and automatically run to the next animate position. Hope this makes sense, you will see what I mean in the <a href="http://jsfiddle.net/EYDtF/" rel="nofollow">fiddle</a>.</p>
<p>Also, I want the animation to automatically run through each slide and 2000ms - and if the slide itself is hovered, I would like it to pause.</p>
<p>I know I'm pretty much asking for someone to write me a custom slider script, but it would so helpful and intuitive to see how a raw one is written with out a plugin.</p>
<p>I need my slider to be lightweight, hence not generating extra markup. Like all the plugins I've tried just are to heavy and too much. I like plain jquery.</p>
<p><br /></p>
<p>Any help would be sooo appreciated. Thanks</p>
<p><br /></p>
<p>Please see my miniature fiddle example using the latest jQuery.</p>

Add label to UITextField

<p>In question <a href="http://stackoverflow.com/questions/663830">663830</a>, Isaac asks about adding a button to a text field. Can someone show code to add a label to the .rightView property?</p>
<p>Or, is there some better way to include 'permanent' text in a text field?</p>
<p>This is for a calculator that would include units in the field (mg, kg, etc.) without having to maintain a label outside of the text field. Sort of like permanent placeholder text?</p>
<p>Thanks,

Comparing Strings Java

<p>I am trying to compare a string to a string value. Seems rather simple, however, the comparison is returning null. All I want is to output the matched value and ignore the null return. But the output is showing the null value as well. I have tried this in various ways, but it keeps showing the null value.</p>
<pre><code> class ActionMovie extends cdinventoryprogram {
private String Atitle;
private double Avalue;
private double Rstock;
private String Ctitle;
public ActionMovie(String title, int itemNumber, int numberofUnits, double unitPrice ){
Atitle = title;
Avalue = numberofUnits * unitPrice;
Rstock = unitPrice * .05;}
public String getActionTitle(){
if (Atitle.equals("Matrix")){
Ctitle = Atitle;
}else if (!Atitle.equals("Matrix")){
}
return Ctitle;
}
</code></pre>
<p>}</p>
<p>public class cdinventoryprogram {</p>

set table cell width with w/ jQuery
|
<p>Ok, here's a puzzler...</p>
<p>I have a table that is drawn dynamically. Categories labels go in YELLOW, items labels in green.</p>
<p><img src="http://i.stack.imgur.com/76YxV.gif" alt="enter image description here"></p>
<p>The area where the table is located is limited, so I need to truncate long labels inside cells using jQuery plugin. The plugin allows using either numeric value for width or "auto", however I would like to add some login to determine what the numeric values should be.</p>
<p>Table width is 700px.
I can also use jQuery to count how many category columns exist.
I also can determine what is the widest label in Green area. Here's my code:</p>
<pre><code>// widest item label (GREEN)
var w = 0;
$(".tData tr td:nth-child(1)").each(function(){
if($(this).width() > w){
w = $(this).width();
}
});
// count category columns (YELLOW)
var colCount = 0;
$(".tData tr:first th:gt(0)").each(function () {
if ($(this).attr("colspan")) {
colCount += +$(this).attr("colspan");
} else {
colCount++;
}
});
var tableWidth = 700,
minWidthCat = 30,
maxWidthCat = 100,
minWidthItem = 100
maxWidthItem = 300;
widthCat = minWidthCat;
widthItem = minWidthItem;
catWmin = Math.floor((tWidth - minWidthCard) / colCount);
catWmax = Math.floor((tWidth - maxWidthCard) / colCount);
// NEED HELP HERE!!!
if () {
}
// truncate categories
$(".tData tr:first th:gt(0)").truncate({
width: widthCat
});
// truncate items
$(".tData tr td:nth-child(1)").truncate({
width: widthItem
});
</code></pre>
<p>Need help with logic that makes the most sense. If I don't have to truncate I rather not set the width for <strong>Category columns</strong>, but they have to be <strong>all the same width</strong>. </p>

Javascript - EMAPI API - Pasting an array into an object

<p>I've got this EMAPI API for my script, and two arrays of latitudes and longtitudes from which a line should be drawn. Theres an api function for this:</p>
<pre><code>obj.push(new EMAPI.Object.PolylineObject({name:'lamana_1', label: 'Łamana 1', labelVisible: true, labelXOffset:-10, labelYOffset:-20, fontSize: 16, fontFamily: 'arial', fontColor:'#339933', lonLat:[new EMAPI.LonLat(19.457817, 51.759553), new EMAPI.LonLat(19.447817, 51.749553), new EMAPI.LonLat(19.453817, 51.744553)]}));
</code></pre>
<p>Specifically I'm concerned with this part:</p>
<pre><code>lonLat:[new EMAPI.LonLat(19.457817, 51.759553), new EMAPI.LonLat(19.447817, 51.749553), new EMAPI.LonLat(19.453817, 51.744553)]
</code></pre>
<p>How do I pass the lons and lats from the mentioned arrays in here? They all have to be in this object for a line to be drawn. I tried nesting a for loop but it gave me nothing.</p>

How to check if a function is callable with parameters?
|
<p>I'm calling a function with call_user_func_array :</p>
<pre><code>call_user_func_array(array($this, 'myFunction'), array('param1', 'param2', 'param3'));
</code></pre>
<p>Everything is ok unless I don't know how many parameters the function needs.
If the function needs 4 parameters it sends me an error, I'd like to test if I can call the function (with an array of parameters).
is_callable() doesn't allow parameters check.
Edit : If the call fails I need to call another function, that's why I need a check.</p>

Enum stubs in Interfaces?
|
<p>I've got an enum defined in one of my Enum.cs classes inside this project where these interfaces lie.</p>
<p>I've got an Interface called IPhoto and in it I need to put a property called FileType because other methods in this service expect it so I want any class implementing IPhoto to have this defined so they know about it.</p>
<p>Does this seem out of place or you just wouldn't do such a thing? How would I define this then?</p>
<p>I mean I can't just do this:</p>
<pre><code>MyEnum FileType;
</code></pre>
<p>The thing is all files have a type. And in my concrete classes I signal that using an Enum (so jpeg, etc.). So any class implementing this needs to definitely have a FileType property somehow.</p>

Method parameters confusion
|
<p>Often time methods take more than 3 parameters which are all of the same type, eg.</p>
<pre><code>void mymethod (String param1, String param2, String param3)
</code></pre>
<p>then it's very easy for the client to mix up the parameters orders, for instance inverting param1 and param2:</p>
<pre><code>mymethod (param2, param1, param3);
</code></pre>
<p>...which can be the cause of much time spent debugging what should be a trivial matter.
Any tips on how to avoid this sort of mistake (apart from unit tests) ?</p>

Android: GameGuardian doesn't find the values of my app?
|
<p>I've created a simple app, with a button and a TextView. My value starts at 100 and is stored in an integer variable. When you press the button the value decreases by 1 and the TextView is updated.</p>
<p>I installed the application on my phone and tried to find the value with GameGuardian... Fortunately for others, unfortunately for me GameGuardian doesn't find my value...</p>
<p>How do I need to change my code so GameGuardian can find it?</p>

How do I make a button switch to a new activity?

<p>I am trying to start a new activity using a button, but the new activity only shows for about five seconds and comes back. This is what my code looks like:</p>

How to modify the following jQuery code so it applies to each li element?

<p>I have the following:</p>
<pre><code>$ul = $('#wpbdp-categories > .wpbdp-categories > li.cat-item > ul');
$('#wpbdp-categories > .wpbdp-categories > li.cat-item > ul').remove();
$('#wpbdp-categories > .wpbdp-categories > li.cat-item').wrapInner('<span>');
$('#wpbdp-categories > .wpbdp-categories > li.cat-item').append($ul);
</code></pre>
<p>Which basically turns sometimes like this:</p>
<pre><code><li>
<a></a>
(10)
<ul></ul>
</li>
</code></pre>
<p>into this:</p>
<pre><code><li>
<span>
<a></a>
(10)
</span>
<ul></ul>
</li>
</code></pre>
<p>The problem is that the page has many <code><li></li></code>.</p>
<p>How to do it so the code is only applied to each <code>li</code> without interfering with the rest?</p>

How do I assign certain scripts to different scenes in Unity 3d?

<p>I was wondering how I can make certain scripts apply to different scenes in Unity 3d. I have a registration form script that I want for the registration scene and a login form script that I want for the login scene. The problem is, when I start the game, it gives me one on top of another. Can anyone help me? If it makes a difference, I'm coding in C#. If its impossible to assign scripts to scenes, then is there an alternate way to do it, like maybe making one invisible while you are logging in and the other invisible when you are registering? Thanks!</p>

Android: how to launch my app upon receiving a specific Broadcast?
|
<p>I am trying to get my app automatically launched when the phone gets connected to wifi. Here's the code I am using to both set the Broadcast receiver and to specify that once the broadcast is received I want the "Connected" activity to be launched:</p>
<pre><code>IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction(WifiManager.SUPPLICANT_CONNECTION_CHANGE_ACTION);
receiver = new BroadcastReceiver(){
public void onReceive(Context context, Intent intent){
Intent intent2 = new Intent(getApplicationContext(),com.example.package.Connected.class);
startActivity(intent2);
}
};
registerReceiver(receiver,intentFilter);
</code></pre>
<p>Unfortunately it's not working. The logcat says my activity has "leaked IntentReceiver".</p>
<p>Does anyone know how I can solve this?</p>
<p><strong>EDIT</strong>: I also tried to register the receiver via the Manifest file. I added this code to the manifest:</p>
<pre><code><receiver android:name="com.example.package.receiver">
<intent-filter>
<action android:name="android.net.wifi.STATE_CHANGE" />
</intent-filter>
</receiver>
</code></pre>
<p>And then this code to my main activity:</p>
<pre><code>private BroadcastReceiver receiver = new BroadcastReceiver(){
public void onReceive(Context context, Intent intent){
Intent intent2 = new Intent(getApplicationContext(),com.example.package.Connected.class);
context.startActivity(intent2);
}
};
</code></pre>
<p>But now my app crashes once the phone connects to wifi. Logcat says "RuntimeException: Unable to instantiate receiver".</p>
<p>Any ideas how to solve it?</p>
