Storing Highlighted text in a variable

<p>Is there a javascript function that will allow me to capture the text that is currently highlighted with the cursor and store it in a variable? I've been trying document.selection.createRange().text but this hasn't been working. Are there any possible alternatives? Here's the code:</p>
<pre><code>function moremagic(){
var output = document.selection.createRange();

Background server in Android
|
<p>I need to program a Background "process" that would periodically buffer certain types of data like A, B, C. These data should be available to different Apps. For example App X receives data A and App Y receives data type B through the background.</p>
<p>What are my best options for designing such a server?</p>
<p>Is "Android Service" the way to go? </p>
<p>Can I have a simple C server running natively as a startup process called by init? If yes, how can I make the data available to the Dalvik Apps?</p>
<p>Could you provide some starting points?</p>
<p>Thanks a lot </p>

checking if a value is one of many constants
|
<p>In Python, you can:</p>
<pre><code>if error_code in (1213,1205,1317,2006,2013):
...
</code></pre>
<p>How can you concisely do the same kind of check - seeing if an int is one of many choices - in Java?</p>
<p>UPDATE: the solution I adopted:</p>
<pre><code>private static final Set<Integer> MySQLRetryCodes =
Collections.unmodifiableSet(new HashSet<Integer>(
Arrays.asList(
1205, // lock timeout
1213, // deadlock
1317,2006,2013 // variations on losing connection to server
)));
</code></pre>
<p>and then later:</p>
<pre><code>if(MySQLRetryCodes.contains(sqlError.getErrorCode()) {

How do you use JavaScript?
|
<p>I'm not a professional programmer, but having a PhD in an engineering field, I've taught myself many programming languages over the years. The past few years I've been using primarily Ruby, and now I'm trying to learn JavaScript so I can do a bit of web programming.</p>
<p>I guess like a lot of people, I had a mostly negative impression of JavaScript going in, but as I'm studying the language (through the book JavaScript: The Good Parts by Crockford), I find that the functional part of the language is really neat. I dabbled in Haskell a few years ago, so I had some idea about functional programming.</p>
<p>I'm wondering how professional programmers tend to use the language. Do you stick to one paradigm when writing in JavaScript, or do you use it like a swiss army knife, and used different paradigms for different problems? Is there a "most popular" way to use it these days, or does it simply depend on the programmer, problem, company, etc.?</p>

Creating a simple text file based search engine
|
<p>I need to create a simple text file based search engine asap (using PHP)! Basically it has to read files in a directory, remove stop and useless words, index each remaining useful word with how many times it appears in each document.</p>
<p>I guess the pseudo code for this is:</p>
<pre>for each file in directory:
read in contents,
compare to stop words,
add each remaining word to array,
count how many times that word appears in document,
add that number to the array,
add the id/name of the file to the array,</pre>
<p>also need to count the total amount of words (after useless removal i guess) in the whole file, which im guessing can be done afterwards as long as i can get the file id from that array and then count the words inside....?</p>
<p>Can anyone help, maybe provide a barebones structure? I think the main bit i need help with is getting the number of times each word appears in the document and adding it to the index array...</p>
<p>Thanks</p>

Jquery .load and inner jquery .append

<p>Ive just started using jquery for the .load ajax functionality. When i load an external page to a specific div it loads fine. inside the external page there is an .append that .appends javascript to the head. This works on the initial load but when i use .load to load it this portion is not showing. </p>
<pre><code>//This is the .load for the div
function loadContent(elementSelector, sourceUrl) {
url = ""+sourceUrl+"";
$(""+elementSelector+"").load(url);
alert(url);
}
//This is the append in the other page that is embedded in a js
var cUrl = "http://intensedebate.com/js/genericCommentWrapper2.php?acct="+idcomments_acct+"&postid="+idcomments_post_id+"&title="+idcomments_post_title+"&url="+idcomments_post_url;
alert(cUrl);
commentScript.type = "text/javascript";
commentScript.src = cUrl;
$('head').append(commentScript);

How can I print error messages from my function when the arguments are invalid?
|
<p>I just started to learn Java. There is a course in MIT and there is <a href="http://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-092-introduction-to-programming-in-java-january-iap-2010/assignments/MIT6_092IAP10_assn02.pdf" rel="nofollow">an assignment</a> to write a class for pay calculation. Part of the task is:</p>
<blockquote>
<ul>
<li>The base pay must not be less than the minimum wage ($8.00 an hour). If it is, print an error.</li>
<li>If the number of hours is greater than 60, print an error message.</li>
</ul>
</blockquote>
<p>The code I have written is as follows:</p>
<pre><code>public class fooCorporation {
private float totalPay;
private float calc;
public float totalPay(double basePay, int hours){
if(hours <= 40){
totalPay = (float) (basePay * hours);
}
else if(hours > 40){
int extraHours = hours - 40;
float payForFortyHours = (float) (basePay * hours);
float payForextraHours = (float) (basePay * 1.5 * extraHours);
totalPay = payForFortyHours + payForextraHours;
}
return totalPay;
}
public static void main(String[] args){
fooCorporation foo = new fooCorporation();
System.out.println("employee 1: " + foo.totalPay(7.50,35));
System.out.println("employee 2: " + foo.totalPay(8.20,47));
System.out.println("employee 3: " + foo.totalPay(10.00,73));
}
}
</code></pre>
<p>The problem I am facing is how to print an error message from the function <code>totalPay()</code> when some conditions are not met. Can the above logic be written in a different way?</p>

Captivate - framework issue

<p>I am a Android developer need quick help on a strange issue with Samsung Captivate. I use <code>android:windowSoftInputMode="adjustPan"</code> for an activity which has a list of EditText in it. The page can expand by adding more EditText views, when it grows long and onFocus of last field soft keyboard pops up and the activity doesn't completely push up. So the EditText view falls behind the soft keyboard.</p>
<p>The strange thing is same the activity and same code moves up without any issues for all other Android devices like HTC Aria, Xeperia, etc. Only Samsung Captivate doesn't move up completely, not sure why its device specific. Is it a framework issue?</p>

<p>When a user clicks on this link a description appears </p>
<p><img src="http://i.stack.imgur.com/TkT0C.jpg" alt="Text appears"></p>
<p>I do this using:</p>
<pre><code><script type="text/javascript">
$(document).ready(function () {
$(".hidden").hide();
$("p.show").click(function () {
$(this).next(".hidden").toggle()
});
$("p.show").hover().css('cursor', 'pointer');
});
</script>
</code></pre>
<p>However I would like the image to change when the text appears. I tried using replaceWith but that didn't work. I am still new to jQuery so any advice is great. I don't need an answer but just a pointer on what is best.</p>
<pre><code><p style="color:Black;float:left;padding-top:0px;" class="show">
<img alt="+" src="resources/images/plussign.jpg" style="float:left; margin-right:10px;"/>What is EFM?<br /></p>
<div class="hidden">
<p style="margin-left:20px;">
<br />EFM, also known as Ethernet in the First Mile, is an Ethernet leased line
service that runs over copper rather than the fibre optic cable used for
other Ethernet services. The copper is provided in bonded pairs, making
the connection extremely robust. If one copper pair fails, the others remain
live, meaning you don’t suffer any downtime and can continue working with
reduced bandwidth until normal service is restored.</p>

How do you make a shared network file read-only using Python?
|
<p>Using Python, what's the correct way to set a file to be read-only when the file is located on a network share (being served from a Windows 2003 Server)?</p>
<p>I'm running Python 2.6.2 in OS X (10.6.1).</p>
<p>The following code throws an exception (as expected) when path is local, but <code>os.chmod</code> appears to have no effect when path points to a Windows share.</p>
<pre><code>import os, stat
path = '/Volumes/Temp/test.txt'
# Create a test file.
open(path, 'w').close()
# Make the file read-only.
os.chmod(path, stat.S_IREAD)
# Try writing to it again. This should fail.
open(path, 'w').close()

Memory Usage estimation

<p>I am wondered about the memory usage of variables and I tried this :</p>
<pre><code>#include <iostream>
int main()
{
char* testChar1 = "Hi";
char* testChar2 = "This is a test variable";
char* testChar3 = "";
std::cout <<sizeof(testChar1)<<std::endl;
std::cout <<sizeof (testChar2) <<std::endl;
std::cout <<sizeof(testChar3)<<std::endl;
}
</code></pre>
<p>output is :</p>
<pre><code>4
4
4
</code></pre>
<p>I think I am not doing the right thing. I want to know how much memory every variable uses in stack .</p>
<p><strong>EDIT 1</strong></p>
<p>At the same time if I does <code>char* testChar3 = NULL</code>; the program crashes. So does it mean there is no memory usage for the same?</p>

jquery will not submit ajax post requests
|
<p>Im having a a few javascript gremlins, for some reason my jquery ajax post request is not going out at all. All of my code 'looks' ok, but javascript is not my strong point, can anybody see where im going wrong?</p>
<pre><code>$(".deleteWeek").click(function(e){
var answer = confirm("This will delete the selected week. Are you sure?");
if(answer){
$.ajax({
type: 'POST',
url: 'http://localhost/todo/index.php/home/ajax_delete',
data: { page_id : $(this).attr('id') },
success: tableRedraw(data),
dataType: 'html'
})
}
e.preventDefault();
})
</code></pre>
<p>and if it helps, my tableRedraw function:</p>
<pre><code>function tableRedraw(data){
$('.week').remove(),
$('thead').after(data)
}
</code></pre>
<p>my click event is definitely being registered, i can put alerts in handler and they come up alright, but as far as firebug is concerned, there is nothing happening on the ajax side. Any help would be hugely appreciated.</p>

Foreach through different objects but all implement same interface possible?

<p>Suppose I have this</p>
<pre><code>interface Movable
{//some stuff}
</code></pre>
<p>And I have</p>
<pre><code>class Car implements Movable
{//some stuff}
</code></pre>
<p>And also maybe I have</p>
<pre><code>class Bike implements Movable
{//some stuff}
</code></pre>
<p>I noticed that if I had this:</p>
<pre><code>ArrayList<Movable> movableThings = new ArrayList<Movable>();
movableThings.add(some kind of Car)
movableThings.add(some kind of Bike)
movableThings.add(some kind of Bike)
</code></pre>
<p>This can be called:</p>
<pre><code>for(Movable m: movableThings)
</code></pre>
<p>But if I call this I get incompatible types:</p>
<pre><code>for(Bike b: movableThings)
</code></pre>
<p>Can someone explain, and maybe offer a better way?
I know I can use foreach Movable m: movableThings and then use instanceof to check for Bikes but is there another way?</p>
<p><strong>Edit:</strong> alright thanks for clarifying guys... so I guess I either use instanceof or redesign my game</p>

Android scaling image vertically
|
<p>I am trying to create a mini progress bar that will indicate how much data a user has used. It doesn't even need to animate, I just need it to change in size based on a variable I have set up. So when I load up the screen, how much of the progress bar is filled up will depend on a variable I have set up in Java.</p>
<p>I have managed to get this working horizontally by using</p>
<pre><code>scale = new ScaleAnimation(0.0f, 1.5f, 1.0f, 1.0f,1.0f, 1.0f);
</code></pre>
<p>This will start the image from nothing and stretching out to its full size, so I can use it as a horizontal progress bar which is great. </p>
<p>Now I woulda thought doing this vertically instead would be a simple matter of just changing the fromY to 0 and the toY to the new size I want. However when I do this, by changing the fromY to 0.0f and the toY to 2.0f, the image actually moves and stretches at the same time rather than stretching. Also the image moves position for some reason. It starts off higher up than where I positioned in using XML, and moves down to the original position and stretches out to the new scale I set up.</p>
<p>The code I use to try and stretch it vertically is</p>
<pre><code>scale = new ScaleAnimation(1.0f, 1.0f, 0.0f, 2.0f, 1.0f, 1.0f);
</code></pre>
<p>So can someone please explain why it stretches horizontally fine, but when I try to stretch it vertically, it suddenly moves and stretchs at the same time.</p>
<p>Would be very grateful for any help.</p>

How can I track the reason why an ASP.NET Session times out?
|
<p>I'm trying to track down an issue on an ASP.NET v3.5 application where the <code>HttpSession</code> times out before its (default) 20 minutes. We're seeing behaviour where the session is lost only a few minutes into a session, at random and with no discernible cause such as unhandled exceptions. As far as I can tell, the ASP.NET worker process is not dying, otherwise that would have explained the dropped session.</p>
<p>What approach should I use to monitor when the session is dropped? Is there some event I can listen to, or some other hook in the <code>System.Web</code> namespace?</p>
<p>Also, can someone confirm that the countdown to expiration is reset by web activity? That is, the session's lifetime gets reset to the (default) 20 minutes each time the web client makes an HTTP GET or POST?</p>

Stop AsyncTask in Fragments when Back Button is pressed
|
<p>i have an activities that host fragments. pressing a button goes from fragment A to fragment B through a FragmentTransaction and the added to the back stack. Now fragment B has an AsyncTask implementation which loads images from an sdcard and publishes it as an image is loaded. if i press the Back button, my app crashes. . The error report indicates that the async task is the problem as it was still loading when the Back button was pressed, so my question is, how can i or where should i stop the AsyncTask when the Back button has been pressed to return to the previous fragment/activity?.. Thank you.</p>

A problem with using System.Collections.Specialized.BitVector32: a bug?
|
<p>I'm trying to do a short simulation where i needed a small bit array, and I chose System.Collections.Specialized.BitVector32. </p>
<p>I'm running it inside a single-threaded object, in a single-threaded loop about 1,000,000 times, each time for indexes {0,1,2}. </p>
<p>Here is the code:</p>
<pre><code>private System.Collections.Specialized.BitVector32 currentCalc
= new System.Collections.Specialized.BitVector32();
private void storeInCurrent(int idx, bool val)
{
currentCalc[idx] = val;
if (currentCalc[idx] != val)
{
throw new Exception("Inconceivable!");
}
}
</code></pre>
<p>To my understanding, the exception should not be thrown, but sometimes it does! An exception is not thrown every time, but in a fair percent - a CONSTANT 1/6 of the time! (which is even stranger)</p>
<p>What am I doing wrong? </p>

How to do a 3-tier using PHP
|
<p>I have a requirement from a client for my PHP Web application to be 3-tier. For example, I would have a web server on Apache in the DMZ, but it should NOT contain any DB connections. It should connect to a Middle server that would host the business objects but be behind the firewall. Then those objects connect to my SQL cluster on another server.</p>
<p>I have actually done this using .NET, but I am not sure how to setup my stack using PHP. I suppose I could have my UI front tier call the middle tier using REST based web services if I create my middle tier as a second web server, but this seems overly complex.</p>
<p>The main reason for this is advanced security: we can not have any passwords on the DMZ first tier web server. The second reason is scalability - to have multiple server on different tiers that can handle the requests. The Last reason is for deployment - it is easier if I can take one set of servers offline for testing before putting them back in production. </p>
<p>Is there a open source project that shows how to do this? The only example I can find is the web server hosting files from a shared drive on another machine (kind of how DotNetNuke pretends to be 3-tier), but that is NOT secure.</p>
<p>Note: I HAVe looked in SO for this answer, and I do see a lot of similar questions, but have not found anyone that actually answered. This is NOT about a Data Access Layer (although I will use it) - my primary question is the design between UI and the Middle Tier.</p>

- implements android.widget.Adapter.getView
- The method getView(int, View, ViewGroup) of type ImageAdapter must override a superclass
method"</p>
<p>Any ideas as to what the problem is?</p>
