1,127,233 | 1,127,234 | Module pattern | Private access to passed in reference | <p>Suppose I have someFunction() that has a public prototype function giveMeAccess() available to the user. </p>

<p>Is there any way to do this?</p>
<p>Yes this has an application as strange as it might seem. I need this info. to model a class hierarchy.</p>
<pre><code>var privateMaker = function ( give_me_access ) {
var Private = {},
someFunction = function(){};
someFunction.prototype = {
public_access: give_me_access
};
return someFunction;
}

<p><strong>Use</strong></p>
<pre><code>var Func1 = new privateMaker();
var private_loot = Func1.public_access();
</code></pre>
<p><strong>Question</strong></p>
<p>How do I give giveMeAccess() access to Private inside of privateMaker()? </p>
<p>Note the prototype function is passed in to the outer function instead of defined in the function as usual. This is the weird caveat.</p>
<p>If this is impossible with this model...then state that as an answer.</p>

I'm on Windows 7 using python 2.7</p>
<p>You guys recommend any 'least strain to the os/hard drive' way to do this?</p>
<p>I was thinking about opening and closing the same file very 10 seconds:</p>
<pre><code>f = open('log_file.txt', 'w')
f.write(information)
f.close()
</code></pre>
<p>Or should I keep it open and just <code>flush()</code> the data and not close it as often?</p>
<p>What about <code>sqllite</code>? Will it improve performance and be less intensive than the open and close file operations?
(Isn't it just a flat file database so == to text file anyways...?)</p>
<p>What about <code>mysql</code> (this uses a local server/process.. not sure the specifics on when/how it saves data to hdd) ?</p>
<p>I'm just worried about not frying my hard drive and improving the performance on this logging procedure. I will be receiving new log information about every 10 seconds, and this will be going on 24/7 24 hours a day.
Your advice?</p>
<p>ie: Think about programs like utorrent that require saving large amounts of data on a constant basis for long periods of time, (my log file is significantly less data that those being written in such "downloader type programs" like utorrent)</p>
<pre><code>import random
import time
def get_data():
letters = 'isn\'t the code obvious'
data = ''
for i in xrange(20):
data += random.choice(letters)
return data
while True:
f = open('log_file.txt', 'w')
f.write(get_data())
f.close()

<p>I thought I had a decent understanding of what was going on until I saw this second example. In the first case, you need the + character so that id 'label' is added to the R file, correct? In the second case, would the EditText's id not be added to the R file because it does not contain the + character?</p>
<p>Also, the second example does not include the android namespace on the id. Does having or not having the Android namespace affect whether that id will be added to the R file?</p>

1,118,432 | 1,118,433 | How can a code in a library project call code in the application project? | <p>In an effort to reduce duplication, I have my app's workspace split into 3 projects:</p>
<ul>
<li>Main (A library project, where all of the common code lives)</li>
<li>Free (To make the free version)</li>
<li>Paid (To make the paid version)</li>
</ul>
<p>Behavior in the free version and the paid version must differ sometimes. How can I "call into" the final projects from the library project?</p>
<p>Here is some sample psuedo-code to illustrate my question:</p>
<h2>In the Main project:</h2>
<pre><code>private void makeADecision() {
if (AppCode.isPaid()) {
// do one thing
} else {
// do something else
}
}
</code></pre>
<h2>In the Free project:</h2>
<pre><code>public class AppCode {
public static bool isPaid() {
return false;
}
}
</code></pre>
<h2>In the Paid project:</h2>
<pre><code>public class AppCode {
public static bool isPaid() {
return true;
}
}
</code></pre>
<p>That is basically what I have tried, but it won't compile because the Main project doesn't know about the AppCode class.</p>
<p>Bear in mind that this is only an example, so try not to focus on how an app can tell if it is the paid version or not. :) So far the best solution I have found is to put a string in the resources of all three projects and then make a decision based on its value but I don't like that method. Besides being ugly, I would prefer to keep functionality where it belongs. That way I can prevent "paid-only" functionality from being compiled into the free version at all and I can avoid having to include any "free-only" code in the paid version.</p>

1,533,557 | 1,533,558 | How do I prevent the slow script warning and force the browser to continue running script until it's finished? | <p>Rather than get overly specific to my problem, I'll keep this generic so other people who stumble upon this can find it useful. </p>
<p>I have a function that accepts one parameter, a string. If the string is short the function runs fine and completes in a timely fashion. If, however, the string that's passed in is too long the script runs for a bit, then eventually times out and returns the browser's slow script dialog that allows the user to kill the script. </p>
<p>I would like to disable that from happening so the script can continue to its terminus.</p>
<p>How can this be done? </p>
<p>A side note: If I can get this working, I would also like to make a status bar, similar to the one you see when loading gmail, appear so the user knows things are happening. </p>

<p>When it is the first row (row 0), I hide v1 in row 0. My worry is that, after row 0 is scrolled out of the window, the converView for row 0 will be reused by other rows. The issue is that, v1 in row 0 has been set to View.GONE in row 0. If other rows reuse the converView for row 0, do I have to set View.Visible to v1? My test shows that I don't have to reset visibility for v1 in the convertView. So I am confused. Doesn't converView conserves the visibility property for each view in it, when the convertView is reused?</p>
