<p>I've so far tinkered with this: </p>
<pre><code>css: {
padding: 0,
margin: 0,

left: '40%',
width: '30%',
color: '#000',
border: '3px solid #aaa',

<p>Any suggestions?</p>

2,603,417 | 2,603,418 | HttpUrlConnection behaving different in Android 2.3 Gingerbread | <p>I'm stumped here. I've been using the same HttpUrlConnection code to retrieve JSON from my server since Android 1.5. Suddenly, with 2.3 it won't work and I can't understand why.</p>
<p>Here's my code:</p>
<pre><code> try {
HttpURLConnection conn =
(HttpURLConnection)(new URL(Constants.SERVER_URL + path)).openConnection();
conn.setAllowUserInteraction(false); // no user interact [like pop up]
conn.setDoOutput(true); // want to send
conn.setDoInput(true);
conn.setRequestMethod( "POST" );
conn.setRequestProperty( "Content-type", "application/x-www-form-urlencoded" );
conn.setRequestProperty( "Accept", "application/json,text/html,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5" );
conn.setRequestProperty( "Accept-Charset", "UTF-8" );
conn.setRequestProperty("Connection", "Keep-Alive");
DataOutputStream pw = new DataOutputStream (conn.getOutputStream());
pw.writeBytes(requestString);
pw.flush();
pw.close();
if (conn.getResponseCode() == 200) {
InputStream in = new BufferedInputStream(conn.getInputStream());
BufferedReader br = new BufferedReader(new InputStreamReader(in));
StringBuffer stringBuffer = new StringBuffer();
while(br.ready()){
stringBuffer.append(br.readLine());
}
br.close();
in.close();
return stringBuffer.toString();
} else {
return badResponse;
}
} catch (Exception ioe) {
return ERROR_MAKING_CONNECTION;
}
</code></pre>
<p>The response comes back with a code of 200, however, when I run conn.getInputStream().available() the result is -1. On every other android api besides 2.3 the conn.getInputStream().available() returns a significant response.</p>
<p>Any ideas?</p>

863,735 | 863,736 | Cookies seen by everyone | <p>Ok, so I want to store some user options in $_COOKIES after form submit.
My code is this:
<code></p>
<pre><code> $reason=array_values(array_filter($_POST['reasontext']));
$str=implode('|',$reason);
if(!isset($_COOKIE['reason'])){
setcookie('reason',$str,time()+86400*30*12);
}elseif(isset($_COOKIE['reason2'])){
setcookie("reason", "", time()-3600);
setcookie("reason",$_COOKIE['reason2'],time()+86400*30*12);
setcookie('reason2', "", time()-3600);
}else{
setcookie("reason", "", time()-3600);
setcookie('reason',$str,time()+86400*30*12);
}
</code></pre>
<p></code></p>
<p>Basically, for an array of let`s say: '1'=>'Test1', '2'=>'Test2', '3'=>'Test3'</p>
<p>The select tool should have had 3 options different for each user, depending on what the user submited as $_POST['reasontext'].</p>
<p>Well this isn`t so, <strong>each user can clearly see what the other one has submited and stored in the cookie which should have been Personal</strong>.</p>
<p>What I want is that each cookie 'reason' to be stored on each users computer and from there to load the different user-customised options. </p>
<p>Any tips? </p>
<p>Thanks in advance for the heads up :)</p>

<p>nothing fancy really. The size of the image is 1000x500 pix. Which load fine when I want to. Problem is I want it to be 2000x1000 which is double that size.</p>
<p>I tried the resize with this code</p>
<pre><code>bmLargeImage = Bitmap.createScaledBitmap(bmLargeImage, 2000, 1000, true);

<p>but it gives me a OOM error. I tried saving the png file as a 2000x1000 pix image and again it gives the OOM exception. This is tested in an emulator so far. But I think the size should be enough to load, what am I missing?</p>
<p>Note: I want it this big cause it's a background to a game (think like farmvile or smurf's village game background) so it should be big and scrollable, yet I only manage the 1000x500 size.</p>

I have created a form in q1.html file, with required div settings. There is a modal.css file to hide/unhide form. There is modal.js file to make the modal box out of this html and css. This html file on its own shows a poping up modal window with it's own "show window" button.</p>
<p>Now, I want to include this html file in one of the php script. If I use a link with an anchor tag pointing to q1.html file, it opens up in an entire new window. That is of no use to use a poping up modal form.</p>
<p>If I use "include('q1.html') file in php, the form stops working. The modal.css applies to the main page where I'm including this file. SO, how do I do it?</p>
<p>I think the problem comes from DOM, as modal.js file asks for elements in html file. But I don't understand how to resolve it.
I was searching on Internet, and all of it returns jquery solutions. At this point I don't want to use jqueary, as I want to learn javascript first.</p>

Has anyone had the following error? Thanks.</p>

trouble processing "javax/net/ServerSocketFactory.class":
[2010-12-06 14:38:16 - HelloGridView]
Attempt to include a core class (java.* or javax.*) in something other
than a core library. It is likely that you have attempted to include
in an application the core library (or a part thereof) from a desktop
virtual machine. This will most assuredly not work. At a minimum, it
jeopardizes the compatibility of your app with future versions of the
platform. It is also often of questionable legality.</p>
<p>If you really intend to build a core library -- which is only
appropriate as part of creating a full virtual machine distribution,
as opposed to compiling an application -- then use the
"--core-library" option to suppress this error message.</p>
<p>If you go ahead and use "--core-library" but are in fact building an
application, then be forewarned that your application will still fail
to build or run, at some point. Please be prepared for angry customers
who find, for example, that your application ceases to function once
they upgrade their operating system. You will be to blame for this
problem.</p>
<p>If you are legitimately using some code that happens to be in a core
package, then the easiest safe alternative you have is to repackage
that code. That is, move the classes in question into your own package
namespace. This means that they will never be in conflict with core
system classes. If you find that you cannot do this, then that is an
indication that the path you are on will ultimately lead to pain,
suffering, grief, and lamentation.</p>

<p>let's say i have an abstract class Animal</p>

Animal(const std::string &name) : _name(name)
{
}
virtual void Print() const = 0;
virtual ~Animal() {}
protected:
std::string _name;
};
</code></pre>
<p>and i have Dog and Cat that inherit this class.
In a book i'm reading it is recommended to define a virtual destructor in base-class.
I tried to create objects without the definition of virtual des' and the program runs fine, without leaks (checked with valgrind).
So my question is why use virtual destructor (with empty implementation)? what is the benefit from it?</p>

<p>What is the difference between order and associativity when evaluating a compound expression?</p>

<p>EDIT:
Our program communicates with Indesign Server which crashes all the time and throws random COM related errors (these errors have to do with bugs in the Server itself). Indesign Server also takes a very long time to process commands so when it crashes, we want to avoid restarting execution. Instead, we want to continue from the line that caused the exception. Any line in the program can cause an exception. So technically, we cannot use a loop.</p>

<p><a href="http://stackoverflow.com/questions/2150078/android-is-software-keyboard-shown">Android: Is software keyboard shown?</a></p>
<p>My activity has a single EditText. I could make it <em>not</em> have focus at activity startup, then add a focuschangelistener to it. When it gains focus, I can do my onVirtualKeyboardShown() stuff. If I could just listen for the back key being pressed in the EditText, I could then interpret that as the virtual keyboard being hidden. Something like:</p>
<pre><code>EditText et = ...;
et.setOnFocusChangedListener(new OnFocusChangedListener() {
public void onFocusChanged(boolean focused) {
if (focused) {
// virtual keyboard probably showing.
}
}
});
et.setKeyListener(new KeyListener() {
public void onKeyPressed(int code) {
if (code == BACK_KEY) [
if (et.isFocused()) {
// virtual keyboard probably hiding.
// lose focus to set up for next time.
et.setFocused(false);
}
}
}
});
</code></pre>
<p>Seems like any approach is fraught with problems given all the differences between virtual keyboards, then we also have to deal with physical keyboards too,</p>

<p>Dear developers and programmers of stackoverflow.</p>
<p>Hello. Thanks a lot for your excellent answers to Panguea, Zengr, Bemace, Thorbjørn, Duffymo, Oswald, Hilal, Skaffman, Starcom and Andy.</p>
<p>Now I have a big picture documented with posters of the Java SE 5/6 with the practical refcards, such as Java Reference Card, Core Java, Java GUI development, Java Collections and JDBC Best practices, etc.
Other interesting answers waere to start with java I/O stream because the programs need data input and data output and Javadoc to have the big picture.</p>
<p>I want to clarify the reason of my question.
I finished the courses, “Java SE 5.0” and “Java EE 5 basic” in the javaPassion website.
Of course, these courses are basic with simple examples, but I had and introduction to Java SE and Java EE.
Today, I feel that I know parts without conection of Java SE and Java EE because they have vast resources.</p>
<p>I want to start to solve simple projects but I have many problems to localize the packages and classes of Java SE to help me solve a simple project.
Also, I can not evaluate if I need only Java SE to solve a project or I would need Java EE to solve the project.
I do not know if I need a methodology to solve a project, or I need more experience and practice and practice with test and error to adquire the ability.</p>
<p>Now my original question change to the next:
How can I solve a project using a programming language such as C, C++ or Java?
Can you give me your opinion or some tips about this question?</p>
<p>Merry Christams and Happy New Year to everyone in stackoverflow site.</p>
<p>Thanks in advance. </p>

<p>Ok, I don't see what this is doing specifically, this part:</p>
<pre><code> new Date(year, month, 32).getDate();
</code></pre>
<p>I know what <code>getDate()</code> does, but then I looked up <code>Date</code> in JavaScript but in this particular example, I don't see why you'd pass 32 here. How can this be returning the number of days in whatever month and year you're passing to it?</p>

1,397,551 | 1,397,552 | Use byte[] as key in Dictionary | <p>I need to use a <code>byte[]</code> as a key in a <code>Dictionary</code>. Since <code>byte[]</code> doesn't override the default <code>GetHashCode</code> method, two separate <code>byte[]</code> objects that contain the same data will use two separate slots in the dictionary. Basically what I want is this:</p>
<pre><code>Dictionary<byte[], string> dict = new Dictionary<byte[], string>();
dict[new byte[] {1,2,3}] = "my string";
string str = dict[new byte[] {1,2,3}];
// I'd like str to be set to "my string" at this point

<p>Is there a simple way to do this? The only thing I can think of would be to build a wrapper class that just contains a <code>byte[]</code> and override <code>GetHashCode</code> based on the contents of the <code>byte[]</code>, but this seems error prone.</p>
