2,231,511 | 2,231,512 | PHP: Image uploading if fail | <p>I am having an upload image system.</p>
<p>You upload a image, then you crop it and press save.</p>
<p>If you cancel this procedure at after you uploaded the image, the image will remain on the server.</p>
<p>So therefore i tried my idea of making a column in db called "failImage", so when you upload the image, it stores the filename e.g 1111.jpg in the column. </p>
<p>So later if you cancel this procedure either by shutting down the website or something else, next time you visit, I made a function that checks if failImage is empty. </p>
<p>If it isn't then it deletes (unlink) the value in failImage(which is in this example 1111.jpg) and emptys the failImage column.</p>
<p>This works fine. </p>
<p>But...if you have two windows of my site, and on the 1)st one you upload a image, and then at the 2nd one you refresh the window(f5) the function i made, that unlink the value in failImage runs, and will then occur an error to the previous window you have open, when you try to crop and save it, as it says no such file or directory, as the second window has removed the image you were working with.</p>
<p>I have thought of an solution to this for some time, is there any way I can solve this?</p>

<p>I have like three different methods which do some respective tasks. Am calling these methods using Hessian from Php client. And am not calling this three methods at a time. Each method will create some arrays(contains strings, int, float), and some time i have to use those arrays which was created my previous methods call in this present method. </p>

Method1(){
String[] stringA = {some string data} ;
}
Method2(){

2,704,644 | 2,704,645 | Non-lvalues as function parameters in C++ | <p>I'm reading Accelerated C++ and in Chapter 4 they bring up the concept of lvalues. There's an example of something that <em>shouldn't</em> work, but after trying it myself I found that it does indeed work.</p>
<p>Specifically they state that, given these functions:</p>
<pre><code>// return an empty vector
vector<double> emptyvec()
{
vector<double> v;
return v;
}
// read things from an input stream into a vector<double>
// (I'm leaving out the function body here because it's irrelevant)
istream &read_things(istream& in, vector<double>& hw);
</code></pre>
<p>This should not be allowed:</p>
<pre><code>read_stuff( cin, emptyvec() );
</code></pre>
<p>Because emptyvec() is an expression and returns a temporary object (a <em>non-lvalue</em> as they called it in the book). However, this not only compiles but actually runs (Windows 7/VisualStudio 2010).</p>
<p>So, what's going on? Was this just a bad example on the authors' part, or is there something else happening that I don't understand.</p>

5,913,141 | 5,913,142 | (JAVA)Terminate function on System.in .. possible? | <p>I am currently working on a project in JAVA where I have to make an agent to interact with a server.</p>
<p>Each 50ms, the server will receive the last thing I outputted to System.out and send me a new set of lines as a 'state' through the System.in printstream to analyze and send my next message to System.out.</p>
<p>Also, if the server receives multiple outputs from me, it only regards the most recent one.</p>
<p>..</p>
<p>As for my question:</p>
<p>My program originally constructed a tree and then analyzed each leaf node to see which would be optimal, and then waited around for the next input, but I can recursively do a deeper tree search that would make my output 'better' (and again and again to keep returning a better result).</p>
<p>Using this and the fact that if the server receives multiple outputs, it only takes the most recent one, I could do each level, print my result and start the next level. But here comes my problem...</p>
<p>I can't be stuck in some complex algorithm while I am supposed to receiving the next input as I will then miss it. So I was wondering if there is a way to cancel anything else I am doing when I receive something via System.in and then go back to the beginning of the function and start the search again with the new set of input (and rinse and repeat..)</p>

4,522,100 | 4,522,101 | Faster version of Convert.ChangeType | <p>In an application that I have, I am doing quite frequent calls to <code>Convert.ChangeType</code> in order to convert a value to a dynamically loaded type. </p>
<p>However, after profiling with ANTS, I've found that this <code>Convert.ChangeType</code> seems to take a significant portion of time (due to being called quite often). Does anyone have a faster alternative to doing this?</p>
<p>At this point I have a type object containing the target, and a <code>string</code> containing the value.</p>
<p>The following is the offending code. I was considering doing a switch-statement on type (since it is a limited collection of types) and calling the parse methods, though I'm not sure whether or not that'll be faster.</p>
<pre><code>if(attributeRow["Value"]!=DBNull.Value)
sample[attr] = attr.AttributeType == typeof(Guid)
? new Guid(attributeRow["Value"].ToString())
: (IComparable)Convert.ChangeType(attributeRow["Value"],attr.AttributeType);

2,236,374 | 2,236,375 | __getattr__ doesn't work with __enter__ -> AttributeError | <p>I would like to use <code>with</code> on an object that uses <code>__getattr__</code> to redirect calls.<br>
Howerver, this does not seem to work with the method <code>__enter__</code></p>
<p>Please consider the following, simplified code to reproduce the error:</p>
<pre><code>class EnterTest(object):
def myenter(self):
pass
def __exit__(self, type, value, traceback):
pass
def __getattr__(self, name):
if name == '__enter__':
return self.myenter
enter_obj = EnterTest()
print getattr(enter_obj, '__enter__')

<p>Output:</p>

Traceback (most recent call last):
File "test.py", line 14, in <module>
with enter_obj:
AttributeError: __enter__
</code></pre>
<p>Why doesn't it fall back to <code>__getattr__</code> since <code>__enter__</code> does not exist on the object?</p>
<p>Of course, I could make it work if I just create an <code>__enter__</code> method and redirect from there instead, but I'm wondering why it doesn't work otherwise.</p>

2,674,553 | 2,674,554 | How to Include JavaScript on a Public Facing Website? | <p>I am building a public facing website and I am using a lot of jQuery and jQueryUI. What I have noticed is that most site on internet that use jQuery and jQueryUI don't have code like this in their pages.</p>
<pre><code><script type="text/javascript">
$(document).ready(function(){
$("a").click(function(event){
alert("Thanks for visiting!");
});
$( "input:submit" ).button();
});
</script>
</code></pre>
<p>I know this is a simplistic example but most sites, for example SO have only one obfuscated js file included for all the pages. It doesn't even seem like they use $(document).ready anywhere. On my current site it seems like I would need to include a js file for each page. My question is how is it suppose to be done and is there a best practice on how to use/include javascript in a page?</p>

1,456,356 | 1,456,357 | Anonymous functions usage | <p>Just wondering what the preferred method of using anonymous functions is.</p>

'title' => 'Title',

}
add_filter('manage_edit-page_columns', 'page_columns');

<p>But I know WordPress discourages using variables for things that will only be used once so I switched it to</p>
<pre><code>function page_columns( $columns ) {

'author' => 'Author',
'template' => 'Template',

507,853 | 507,854 | Animation BEFORE activity change | <p>I'm trying to do something simple, but I can't understand why it's not working.<br>
What I'm trying to do is: when I touch an ImageView, it will show an animation on it. And then, only when that animation ends it will start the new activity.<br>
Instead, what happens is that the new activity starts right away and the animation is not shown.</p>
<p>Here is the animation xml:</p>
<pre><code><rotate android:interpolator="@android:anim/decelerate_interpolator"
android:fromDegrees="-45"
android:toDegrees="-10"
android:pivotX="90%"
android:pivotY="10%"
android:repeatCount="3"
android:fillAfter="false"
android:duration="10000" />
</code></pre>
<p>And this is the code I use to call it:</p>
<pre><code>public void onCreate( Bundle savedInstanceState )
{
final ImageView ib = (ImageView)this.findViewById( R.id.photo );
ib.setOnClickListener( new OnClickListener( ) {
@Override
public void onClick( View v )
{
Animation hang_fall = AnimationUtils.loadAnimation( Curriculum.this, R.anim.hang_fall );
v.startAnimation( hang_fall );
Intent i = new Intent( ThisActivity.this, NextActivity.class );
ThisActivity.this.startActivity( i );
}// end onClick
} );
}// end onCreate
</code></pre>
<p>As you see I tried putting a loooong time for the animation, but it doesn't work. The NextActivity starts right away, it doesn't wait for the animation in ThisActivity to finish.<br>
Any idea on why this happens?</p>
