647,749 | 647,750 | How to sort 3D array in c#, with each row is specific to one entry if 1D array? | <p>Please guide me as how to sort an array with taking into consideration that each row is specific to one specific column value. For example,</p>
<p>1D array<br>
5<br>
3<br>
4 </p>
<p>2D array<br>
1,2,3<br>
3,4,5<br>
6,7,8 </p>
<p>In above example,let say, 5 (In 1Darray) is associated with the first row of 2d array (1,2,3). Similary, 3 in 1d array is associated with second row of 2d array(3,4,5).And similarly for the third entry of 4 (of 1d array). Now I want to sort the 1D array with taking into consideration that the associated rows with each 1D array element also change accordingly. I mean its kind of auto-arrangment of rows with change of column values. Please guide Regards Asad</p>

<p>Edit: to be clear, the mooted organization is to have a jar with the constant objects, and a separate jar with the swappable object. Runtime swappability is neither expected nor sought. Remote installation and runtime swapping is probably more sophisticated than necessary for my needs. </p>

<p>I apologize if this is already covered somewhere. I did a search and find something which I have already implemented.</p>
<p>I am developing an application which receives data from a device connected via serialport. I am using SerialPort datareceived event to capture data. I am to display data in text boxes of the main form. Data is received frequently. I used Timer to send command to the device, in response device send some data. Timer interval is 100 ms. In every 100 ms interval some command is sent and correspondingly data is received. I used Invoke function to update the GUI elements like TExtbox, labels etc. Everything is fine. All the elements are updating beautifully. But during receiving data if I make any change in main form like moving form, minimizing, maximizing, or clicking somewhere in the form, then data receiving stops. I couldnot find the reason why its happening ? I also changed the timer interval to 200,300,400,500 but same problem is there. </p>
<p>Please tell me why its happening? And possible solution...</p>
<p>Thanks In advance.... :)</p>

// (that is what I want with my object)

<p>I'm quite new to Java and realize that I'm probably missing some fundamental concept, but any feedback would be appreciated. Thank you.</p>
<p>Edit:
The responses about overriding the toString method were helpful, but it's not quite doing what I had in mind, here's a better example of what I want:</p>
<pre><code>Double mydouble = new Double ( 20.1 ) ;
System.out.println ( mydouble + 10.1 ) ; // prints 30.2
</code></pre>
<p>How would I do this with my own object (assuming I want the default value to be a double)?</p>
<p>Thanks again.</p>
<p>Final Edit (hopefully):
Your answers were enough to lead me to learn more about Primitive Wrappers and Autounboxing. My understanding is that there's no way to do what I want (which at this point, I would describe as autounboxing my object as a double), or at least I'll save that for another question. Cheers.</p>

4,686,144 | 4,686,145 | android monitoring apps | <p>I would like to create an Android application with real-time monitoring functions. One monitoring function is to audit the audio flow.

<p>I am considering how to design the Android application. </p>

2: // perform other work here ...
// Set another completion function for the request above
3: jqxhr.always(function() { alert("second complete"); });

<hr>
<h2>2 Questions :</h2>
<p><strong>1)</strong> I heard that the callback functions <strong>arguments</strong> of <code>success</code> , <code>error</code> , <code>complete</code> being transferred to <code>done</code> , <code>fail</code> , <code>always</code> respectively.</p>
<p><img src="http://i.stack.imgur.com/j4vi1.jpg" alt="enter image description here"></p>
<p>So If I want to use the <strong>jqXHR</strong> obj in always callback , How can i know from where he came (<code>error</code> or <code>success</code>) - because the <code>params order</code> in the method signature is <strong>different</strong> !!!</p>
<pre><code>//here it is at place 3

<p><strong>2)</strong> I also heard that Defered Objects help us to build the callback Function dynamically.
(as we can see in '<code>3:</code>')</p>
<p>I dont understant why will I ever need it ? by the time I got the Section <code>3:</code> - the ajax call has <strong>already</strong> been made and alerted completed , In what scenarios the section <code>3:</code> comes into action ?</p>
