5,997,789 | 5,997,790 | Should I use several activities for an app with several screens? | <p>I'm new to Android and I'm building a simple application to start with. It consists of a client with three screens. In the first screen the user is prompted for an Ip to connect to a server (I use an EditText and a button). If the connection is successfully established, some data will be retrieved from the server and the client will show the data on a blank screen (I use a TextView). This would be the second screen. Then, the user could ask the server for detailed information about any data that has been retrieved from the server, which would be the third screen (I use a TextView again).</p>
<p>The problem is that I don't know what's the best way to go about it. I have currently one activity and one XML file containing all the components of the view (EditText, button, TextView). Until now, I've been using <code>setVisibility(View.GONE);</code>to hide certain components depending on the screen the user is in. (For example in the first screen I have to hide both TextViews).</p>
<p>One of the problems I'm facing is that when I put the phone in a horizontal position the components I had hidden show up again. I don't know if hiding views is the ideal thing to do for my purpose. </p>
<p>I've thought that maybe I should use more than one activity, shouldn't I?</p>
<p>I really appreciate any help you can give me to structure my first app.</p>

873,407 | 873,408 | Android app that needs to use non-memory SD card | <p>I'm contemplating making an android version of my iPhone app. One of the attractions is the availability of a micro/miniSD card from Spectec that has an Ant+ radio in it, to communicate with Ant+ protocol devices. </p>
<p>The technical feasibility of this is not my question; but rather its practicality:</p>
<p>This obviously involves taking out the SD memory card in the handset and replacing it with one with no on-board memory, leaving the device with only the builtin 256mb or whatever. this is plenty for my app, but I'm concerned that, aside from annoying the user by having all their music removed, there will be apps on the users device that save data to the SD and will be broken by removing the SD memory. </p>
<p>Can anyone give an opinion on this issue?</p>

2,427,400 | 2,427,401 | Shouldn't this Python function return 6 all the time? | <p>I am new to Python and learning about functions. I came across the following function and at my wits end understanding how it works. It seems to me no matter the value of <code>b</code>, the answer should always be six but that isn't the case.</p>
<p><em><strong>CODE</em></strong></p>
<pre><code>def mult(a, b):
if b == 0:
return 0
rest = mult(a, b - 1)
value = a + rest
return value
print "3 * 2 = ", mult(3, 2)
</code></pre>
<p>My understanding of what happens</p>
<ol>
<li>Since <code>b</code> is not 0 it proceeds</li>
<li><code>rest</code> is assigned the value <code>3, 1</code> and it runs the function again</li>
<li>Since <code>b</code> is 1 and does to equate to 0, it proceeds to <code>rest</code></li>
<li><code>rest</code> is assigned the value <code>3, 0</code> and it runs the function again</li>
<li>Since <code>b</code> is now zero it returns the value 0</li>
<li>It then proceeds to <code>value</code> which has the value 3 + 3 as <code>a</code> had the value of 3 and <code>rest</code> had the value of 3 i.e. <code>(3,0)</code></li>
<li>It returns the value 6</li>
</ol>
<p><strong>But</strong> if I assign <code>mult(3,4)</code>, it returns the value 12. Following my understanding, that isn't possible. Clearly, I am not understanding the logic flow. What am I doing wrong?</p>

<p>On catch (exception& e), it says:</p>
<blockquote>
<p>We have placed a handler that catches exception objects by reference (notice the ampersand & after the type), therefore this catches also classes derived from exception, like our myex object of class myexception.</p>

<p>Does this mean that by using "&" you can also catch exception of the parent class? I thought & is predefined in std::exception because it's better to pass e (std::exception) as reference than object.</p>

5,212,336 | 5,212,337 | Letting a third party app start my activity directly? | <p>I'm working on an activity which other 3rd parties want to use in their own apps, via intents.</p>
<p>Right now this activity is catching urls via an intent filter, like this:</p>
<pre><code><activity android:name=".MyActivity">
<intent-filter>
<action android:name="android.intent.action.VIEW"></action>
<category android:name="android.intent.category.DEFAULT"></category>
<category android:name="android.intent.category.BROWSABLE"></category>
<data android:host="www.mysite.com" android:pathPrefix="/test/" android:scheme="http"></data>
</intent-filter>
</activity>
</code></pre>
<p>The above works, whenever a user clicks a link in my app like:</p>
<p>"mysite.com/test/blah.html"</p>
<p>my app comes up as a choice, along with the browser, to open the link.</p>
<p>Now if a third party wants to use my app, I think they can use the above like this:</p>
<pre><code>Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://mysite.com/test/somedata"));
startActivity(intent);
</code></pre>
<p>While this would work, this probably won't give them the desired effect of jumping directly to my activity from theirs - the android chooser dialog will appear, asking if they want to open the intent data with the browser, or my app.</p>
<p>How can I let 3rd parties call my activity directly without broadcasting the intent like this? I'd like to make them still pass the same exact data scheme to me, but just let them open my activity directly.</p>

3,956,027 | 3,956,028 | Keep track of the lifetime of a child process in C# | <p>Part of our job is interfacing with an ERP system. Some of the processes within that system can be automated by calling a specific exe called IMPAUT.exe in the base directory of the ERP system. I pass the ERP sub program ID to IMPAUT and it fires off.</p>
<p>Now, what IMPAUT does is determines if the ERP installation is a client or standalone installation, and then IMPAUT fires off a child process. This child process is either IMPACT.exe or IMPCSC.exe. Once IMPAUT has fired off the child process, IMPAUT dies. The child process continues to live for a while. The child process only dies when it has completed the command and has logged out of the ERP system.</p>
<p>The problem is, that while the child process is still alive, I can't call IMPAUT again, because only one instance of the child program may be logged in to the ERP system. I also can't monitor when IMPAUT dies, because the child process will still be alive long after IMPAUT has died.</p>
<p>I need to determine when the child process has died for the specific IMPAUT process that invoked it. So from the parent, I need to get the child process it invokes, before the parent process has died and monitor that child process' lifetime.</p>

3,775,930 | 3,775,931 | Private variables in inherited prototypes | <p>I think I have misunderstood how Javascript prototypal inheritance works. Specifically, the prototypes internal variables seem to be shared between multiple different sub-objects. It is easiest to illustrate with code:</p>
<pre><code>var A = function()
{
var internal = 0;
this.Increment = function()
{
return ++internal;
};
};
var B = function() {};
// inherit from A
B.prototype = new A;
x = new B;
y = new B;
$('#hello').text(x.Increment() + " - " + y.Increment());
</code></pre>
<p>This outputs <code>1 - 2</code> (test it on <a href="http://jsbin.com/ateci3/2/edit" rel="nofollow">JSBin</a>), while I fully expected the result to be <code>1 - 1</code>, since I wanted two separate objects.</p>
<p>How can I make sure that the <code>A</code> object isn't shared object between multiple instances of <code>B</code>?</p>
<p><strong>Update</strong>: <a href="http://robertnyman.com/2008/10/21/javascript-inheritance-experimenting-with-syntax-alternatives-and-private-variables/" rel="nofollow">This article</a> highlights some of the issues:</p>
<blockquote>
<p>The problem is that the scope each approach uses to create a private variable, which works fine, is also the closure, in action, that results in if you change a private variable for one object instance, it is being changed for all. I.e. it’s more like a private static property, than an actual private variable.</p>
<p>So, if you want to have something private, more like a non-public constant, any of the above approaches is good, but not for actual private variables. Private variables only work really well with singleton objects in JavaScript.</p>
</blockquote>
<p><strong>Solution</strong>: As per BGerrissen's answer, changing the declaration of <code>B</code> and leaving of the prototype works as intended:</p>
<pre><code>var B = function() { A.apply(this, arguments); };

<p>In the xxx I would like to give the field name and yyy the actual value. Maybe inside the function I could do some kind of casting with a case method based on the field name. I only have a small number of field names so that could be easy. Also maybe there is a way I could find the datatype from reflection of the vm class but that's far beyond my knowledge. </p>

4,710,174 | 4,710,175 | Chained PHP controls | <p>I'm making a form validation class and it works like this currently.</p>
<pre><code>$validator->setVar($_POST['Username'])
->standardFilter(array('XSS', 'SQL_INJECTION'))
->customRegex()
->replace('This', 'With this')
->getResult();
</code></pre>
<p>While it works perfectly when chained like this, I can't archieve the following result.</p>
<pre><code>$validator->setVar($_POST['Username'])
->isValidEmail()
->isValidPhoneNumber()
->isSet()
->isNull()
->getResult()
</code></pre>
<p>For example, script returns the following values</p>
<pre><code>->isValidEmail() (true)
->isValidPhoneNumber() (true)
->isSet() (false)
</code></pre>
<p>Basically, I'm going to make an array, fill it with true/false depending on the result of each function, and I'll look for a specific value in array (a false). If it exists, the class will return false regardless of the rest of the chains. (or I can just override variables, not important here.)</p>
<p>However, I want $validator to stop chaining once it gets a false from a function. Let's say it received a false from isSet(). It shouldn't execute isNull() and getResult() since we already have a failed check.</p>
<p>How can I archieve this in PHP?</p>
<p><strong>TL;DR:</strong></p>
<pre><code>var_dump($validator->setVar('Test message')->isInteger()->setTrue());
//false //true
Output: false, because once isInteger() failed, rest of the chain isn't executed.

3,139,551 | 3,139,552 | How can I conditionally define a function in javascript? | <p>Consider the following script:</p>
<pre><code>if (false) {
function foo() {
alert("FOO");
}
}
foo(); // alerts "FOO"
</code></pre>
<p>As you can see, the function <code>foo</code> is defined and works even though the condition for the <code>if</code> fails.</p>
<p>The reason I want to do this is that I am developing an extension for InDesign and I made a script called utilities.jsx which holds various functions which are used in other scripts. In all the scripts that need these functions, I simply use:</p>
<pre><code>app.doScript(File(scriptsFile.parent.fsName + "/t_utilities.jsx"), ScriptLanguage.JAVASCRIPT);
</code></pre>
<p>which defines all the functions I need and then I can use them. Now, since this script will be called multiple times by various files in an unpredictable order (the user decides), I thought I might only define the functions if they haven't been defined before (if utilities.jsx hasn't run yet). Kind of like <code>require_once</code> in php.</p>
<p>I was thinking of something like the following, but that doesn't work as the functions are defined every time the script is run:`</p>
<pre><code>var utilitiesHasRun;
if (utilitiesHasRun !== true) {
// define all the functions
// ...
utilitiesHasRun = true;
}
</code></pre>
<p>Are there any other options?</p>

2,723,889 | 2,723,890 | Watermark 2000+ images at once? | <p>I have a image hosting service and people upload offline (they upload to another computer like a station without internet access) and then we sync the images (they aren't watermarked at this stage) and they are not approved at this point.</p>
<p>There is an admin area where the user would go to approve an image, and we will apply the watermark at this stage.</p>
<p>I am wondering what method would be best to watermark 2000ish images using PHP (at a time). Would creating a system daemon and waiting for a response a good idea or?</p>
