myNewCustomEvent.fire(10);
// myHandler prints 10

<p>I can do this pretty easily with a simple class -- but when i want to have an event that passes a different type or amount of arguments to the subscriber i have to write, and define an entirely new event class.. I figure there has to be some library, or maybe even something native in Visual C++ 2008 that will work something similar to this.

To make my future secure and at least get good jobs, I have started learning C++; I have learned J2SE, ASP.NET (little, basic C#), PHP (little), HTML, CSS, AJAX, Javascript, SQL, a little android development (I have built a benchmark app) in 4 months and have received 1 gold medal in CSS and 1 each in HTML, CSS, Java. </p>
<p>I am able to make things in C#, Java and all other, so I can apply all this knowledge. I was able to do all this, because I loved learning and I hate to ask this question. How much time would it take me to learn C++, good-enough to get good jobs at Google, Microsoft? I am currently learning data structures, so that's excluded.</p>

<p>When the commented two lines above the while loop are uncommented, it throws an exception <code>java.util.ConcurrentModificationException</code>. If those commented lines are placed above this line <code>Iterator<String>listIterator=list.iterator();</code>, it works well. Such exceptions are very common while handling entities in <strong>EJBs</strong>. Why does this happen? How can it be avoided?</p>

<p>I'm doing some basic quiz application and it has a backend. On my backend, I am setting up a quiz for students to answer. One of my interface is like this.</p>
<p><img src="http://i.stack.imgur.com/ELwTk.png" alt="enter image description here"></p>
<p>If the user checked the box, it means 1950 is the answer. How would I process that one in my database to determine that 1950 has been the answer of the question.</p>
<p>My Database is like this.</p>
<pre><code>tbl_choices
Id,Choice,isAnswer
</code></pre>
<p>so ideally, it would be stored like this.</p>
<pre><code>tbl_choices
ID CHOICE isAnswer
001 1900 0
002 1800 0
003 1950 1
004 1850 0
</code></pre>
<p>My question here is how would I code it in a sense when a user will check the checkbox and the textinput right beside it will have a value of <code>isAnswer</code> as <code>1</code>.</p>
<p>Just an additional info: When a user will click that <code>+</code> button it will add a new textinput and if user will click <code>-</code> button it will delete a textinput, but I got that all covered.</p>
<p>The choices are dynamic, it will changed, that above that I've shown you is just an example.</p>

<ol>
<li>User inputs grade for a prospect (B+ for prospect1)</li>

<p>I believe I have step 2 covered but I am iffy on how to complete the rest of the code.</p>
<p>To simplify things, let's say we are given a list of 5 prospects. Users will grade each of them. As each additional user adds their input of grades, the average grade of each prospect should be updated and the order of their ranking simultaneously sorted. </p>

def numbergrade(lettergrade):

I see the benefits with Java and wish to dig deeper.</p>
<p>All the documentation though is too advanced for me atm.</p>
<p>A typical PHP structure:</p>
<pre><code>index.php
classes/class_get.php
classes/class_set.php
</code></pre>
<p>Where in index.php you would have the lines</p>
<pre><code>require_once "classes/class_get.php";
require_once "classes/class_set.php";
</code></pre>
<p>Now in Java...
I understand Windows files are in .JAR format. No problem here, easy to understand.
I am confused when creating this in eclipse. Is the strucutre;</p>
<pre><code>Main.java
src*/defaultPackage**/myClass.java
</code></pre>
<p>* folder<br>
** package</p>
<p>Where in the Main.java file you would declare "import myClass.java"?</p>
<p>Also other packages such as the following:</p>
<pre><code>import java.awt.*;
import java.awt.event.*;
import java.net.URL;
import javax.swing.*;

4,053,593 | 4,053,594 | android background issue | <p>I'm having an issue with my background. Depending on my manifest settings I either have the background being squished when i bring up a soft keyboard like this:</p>
<p>![enter image description here][1]</p>
<p>Or else I get this with the graphics being pushed off the screen:
![enter image description here][2]</p>
<p>If I tap the black area the graphics come down, but now the EditText is pushed down like this:
![enter image description here][3]</p>
<p>How do I fix this? The top should always look like the last image, but I should always see the edittext.</p>

2,953,090 | 2,953,091 | Any way to tell when any button in a layout is UN-pressed | <p>(Android 3.2) I have a TableLayout with 9 buttons.

I don't care which button, I just want to know when any button which had been pressed has just been released.</p>
<p>I was hoping there was an <strong>Android::onTouch</strong> in the XML, like there is an Android::onClick, and I could point them all at one onTouch event handler to look for an ACTION_UP. But there isn't. I'm trying to avoid writing 9 separate OnTouchListeners.</p>
<p>Any suggestions?</p>
