787,938 | 787,939 | How can I make my android tablet app to look the same when it runs on phone in landscape mdoe | <p>I have a android app layout for tablet. Its layout is 'landscape' based (i.e. it looks the way i want when I run on tablet (by default landscape).</p>
<p>But when I run the same app on a phone, android runs in portrait mode, (it squeeze my 'landscape' layout into a portrait ). </p>
<p>I have tried putting 'android:screenOrientation='landscape' in my activity in my Manifest file. But that does not fix it.</p>
<p>Basically, what I want is when I rotate the phone by 90 % (the width is > height), I want the phone layout looks the same as what i see on tablet (which is landscape by default).</p>
<p>How can I do that? android:screenOrientation='landscape' does not work.</p>
<p>Basically, I want some thing the game 'AngryBird', it always runs in landscape mode regardless it is phone or tablet and whether the phone is rotated.</p>

1,496,536 | 1,496,537 | Where to put functionality of serializing a custom class? | <p>I'm starting to work with the serialization now and I think I got my class serializable after asking <a href="http://stackoverflow.com/questions/15488330/storing-and-retrieving-data-from-an-xml-file">here</a>.</p>
<p>Now I wonder if it's regarded a good, bad, depending or indifferent design to place the serialization methods <strong>inside</strong> the said class.</p>
<p>Suppose I have my class like this.</p>
<pre><code>[XmlRoot("Settings")]
public class SerializableClass
{
public SerializableClass() { }
[XmlElement("PropertyOne")]
public String PropertyString { get; set; }
[XmlElement("PropertyTwo")]
public int PropertyInt { get; set; }
public Object PropertyObject { get; set; }
}
</code></pre>
<p>Would it make sense to add methods like these, to let the object (de)serialize itself?</p>
<pre><code>public String SerializeMe()
{
XmlSerializer serializer = new XmlSerializer(typeof(SerializableClass));
StringWriter writer = new StringWriter();
serializer.Serialize(writer, this);
return writer.ToString();
}
public static SerializableClass DeSerialize(String input)
{
StringReader reader = new StringReader(input);
XmlSerializer serializer = new XmlSerializer(SerializableClass);
return xmlSerializer.Deserialize(reader) as SerializableClass;
}
</code></pre>
<p>I would, of course, implement these with <em>try-catch</em>, <em>using</em> and some kind of file reader and only specify the path. Is it doable? Recommended? Common? (I've never used serialization implemented by me, so please bear with me if the question seems strange.)</p>

<p>Here is an example:</p>
<p><code>Sun: 10:00 – 3:00pm</code></p>
<p>I don't know if the dash will show up on here.. but when it is inserted into my table, it is like a square box with the characters <code>0096</code></p>
<p>It looks a lot like an <code>&ndash;</code> - when viewing the source, there is no special characters, just the dash.</p>
<pre><code>str_replace('–', '', $var);

<p>The above replace doesn't seem to catch it, has anyone else had this trouble before?</p>

4,008,547 | 4,008,548 | Propagating data among view controllers | <p>I've got a table view controller. Some of the rows of the table open new controllers to let the user enter more data or use pickers, etc. It's just like the built-in Calendar app. When the user taps "Save" on the second screen, I want the value from that screen to propagate back up into the table view controller, but I don't know how to do it. Since I'm using pushNavigationController to get to the second screen, there's no opportunity to provide a pointer back into the original object. (That seems like really bad design even if it were possible since the second controller would have to know stuff about its parent.)</p>
<p>Also, from testing, it seems like pushNavigationController doesn't 'pause' the original controller so you don't just resume on the next line of code once the second screen is popped.</p>

1,781,217 | 1,781,218 | aspnet command line tools location | <p>Microsoft provides a number of command line tools for working with asp.net applications. I haven't had any trouble using these tools. One thing that I can not understand though, is the location of these tools.</p>
<p>Even for applications targeting newer versions of .net, these tools are located in the .net v2 directory. On my machine, that's <code>C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727</code>. Why do these tools not exist in the <code>v3.0</code> or <code>v3.5</code> directories? And why do the ones in the older directory work on the newer framework?</p>
<p>This is more of an idle curiosity than required knowledge for me, but I would like to know.</p>
<h2>Update:</h2>
<p>Thanks for the good answers everyone. These answers raise a new question though. I hope you will forgive me for asking it here, since it is so highly related. If .net 3.5 is really just using the CLR from 2.0, why is 2.0 compatible with Windows 2000, but not 3.5? It would seem to me that if the updates in 3.0 and 3.5 run inside the framework of the earlier version, then they must maintain compatibility with the same platforms as the earlier version too. Why is this wrong?</p>

<p>The value here "<code>myValue</code>" gets read out of a database by php. This value can also be a text with more than one lines (it contains at least one or more linebreaks). If I write these values in the code, it gives me a JavaScript Exception:</p>

<blockquote>
<p>Write a method named pow2 (a variation of the previous pow exercise)
that accepts a real number base and an integer exponent as parameters
and returns the base raised to the given power. Your code should work
for both positive and negative exponents. For example, the call
pow2(2.0, -2) returns 0.25. Do not use Math.pow in your solution.</p>

double total=1;
for(int i=1;i<=y;i++){
total*=x;
}
return total;
}
</code></pre>
<p>But the problem is when I try to call <code>pow(2.0, -2)</code>, it returns me 1.0 instead. How should I approach doing this question? Another inquiry - I dont understand how it even returns me 1.0. Shouldn't it have been the result of 2*(-2)*(-2)?</p>
