<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>

2,900,428 | 2,900,429 | How to place ImageButton at x, y location? | <p>I want to place ImageButton at x, y location of my view.
The problem is that Android adds padding around image.
Because I don't know exact size of padding, I cannot place image button at exact location.
So, I want to remove padding.
How can I remove padding around image programmatically?
button.setPadding(0, 0, 0, 0) makes button width shorter and height longer than bitmap.
button.getLayoutParams().width gives minus value.
What I tried so far is like this. </p>
<pre><code>protected class MyLayout extends RelativeLayout {
Bitmap img;
ImageButton button;
public MyLayout(Context context) {
button = new ImageButton(context);
img = BitmapFactory.decodeResource(getResources(), R.drawable.img);
button.setImageBitmap(img);
params = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
button.setLayoutParams(params);
params.setMargins(x, y, 0, 0);
button.setBackgroundDrawable(null);
addView(button, params);
}
}

2,804,146 | 2,804,147 | Dealing with rapid tapping on Buttons | <p>I have a Button with an OnClickListener. For illustrative purposes, consider a button that shows a modal dialog:</p>
<pre><code>public class SomeActivity ... {
protected void onCreate(Bundle state) {
super.onCreate(state);
findViewById(R.id.ok_button).setOnClickListener(
new View.OnClickListener() {
public void onClick(View v) {
// This should block input
new AlertDialog.Builder(SomeActivity.this)
.setCancelable(true)
.show();
}
});
}
</code></pre>
<p>Under normal usage, the alert dialog appears and blocks further input. Users must dismiss the dialog before they can tap the button again.</p>
<p>But sometimes the button's OnClickListener is called twice before the dialog appears. You can duplicate this fairly easily by tapping really fast on the button. I generally have to try several times before it happens, but sooner or later I'll trigger multiple onClick(...) calls before the dialog blocks input.</p>
<p>I see this behavior in Android 2.1 on the Motorola Droid phone. We've received 4 crash reports in the Market, indicating this occasionally happens to people.</p>
<p>Depending on what our OnClickListeners do, this causes all sorts of havoc. How can we guarantee that blocking dialogs actually block input after the first tap?</p>

<p>Problem is, I have a button that allows you to remove a row.</p>

$('table.data tr:nth-child(even)').css('background-color', '#ffffff');

<p>I have two <code><a></code>s contained in the "main" div. One is directly under the div while the other is buried under a couple of sub-divs. When it runs, it only adds the blank target to the first <code><a></code> tag. However, when I set a breakpoint through Firebug and step through it, everything works fine. Is there a reason it wouldn't work at full speed? What's the workaround?</p>

736,257 | 736,258 | Mixed Results for Class Method | <p>I use PHP with the Codeigniter framework, and often have methods in my classes that return an array of values. It makes things simpler in my views if there are no records returned, that the method return FALSE or NULL, rather than returning an empty array. In my views I can just have something like:</p>
<pre><code><?php if($abc_array) : ?>
// loop through the array, etc.
<?php else : ?>
// show some message
<?php endif; ?>
</code></pre>
<p>If I return an empty array, I end up including something like the following in the views:</p>
<pre><code><?php if(is_array($abc_array) AND count($abc_array) > 0) : ?>

<p>I guess this is kind of a trivial example, but I'm mainly wondering if it is considered bad practice to have class methods return mixed result types. What about if a mysql error is somehow generated in the class and caught, should I have the returned result types something like:</p>
<p>FALSE (on some type of error)</p>
<p>Empty Array (if no results were returned)</p>
<p>Array of Results (results were returned)</p>

4,089,484 | 4,089,485 | How to implement a less generic std::is_constructible with decltype | <p>I'm going out on a limb here, assuming that it is possible but I'm not quite sure. Basically what I'm looking for is a way to switch at compile-time between using a default constructor or a constructor that takes one argument by reference.</p>
<p>i.e.</p>
<pre><code>T* create<T>()
{
return new T(1); // if possible
}
T* create<T>()
{
return new T(); // fallback to here
}
</code></pre>
<p>I'm using the VS2010 compiler and it does not support <code>std::is_constructible</code> but I can use <code>decltype</code>.</p>
<p>I went digging in the VS2012 type_traits header and looked at the <code>std::is_constructible</code> implementation and well I got a bit turned around. I don't get it how people write code that way. The headers are the most convoluted piece of code I've ever seen. Anyway, I saw that it was using decltype and it got me think, hopefully someone with more experienced can provide me with an answer.</p>
<p><strong>After going through @ipc's answer I've settled on the following code</strong></p>
<pre><code>// std::declval is not supported by VS2010
template <typename T> typename std::add_rvalue_reference<T>::type declval();
template <class T, class R0>
decltype(new T(declval<R0>()))
createInstance_(R0& r0, int = 0)
{
return new T(r0);
}
template <class T, class R0>
T*
createInstance_(R0&, ...)
{
return new T();
}
</code></pre>
<p>The above code will work but it does confuse the IntelliSense Engine, anyway I thought it was nice that you could omit the extra function by simply using a default argument. I've tested this code with VS 2010 and it compiles fine and runs as expected.</p>
