1,148,833 | 1,148,834 | Using $_POST information only once | <p>I have some information which gets passed from a form and needs to be used once and only once. I can collect it nicely from $_POST but I'm not sure which is the "best" way to ensure that I can only use it once, i.e. I want to avoid the user pressing F5 repeatedly and accessing the function more than once. </p>
<p>My initial thought was to set a session variable and time the function out for a set period of time. The problem with that is thay could have access to the function again after the set period has elapsed.</p>

</blockquote>
<p>I am looking at somebodies code and there are several dozen constants defined in a class like this:</p>
<pre><code>// header file
class Defines
{
public:
static const int Val1;
static const int ValN;
static const char* String1;
static const char* StringN;
...
}
// .CPP
const char* Defines::String1 = "some value"
etc.
</code></pre>
<p>Is there some reason to do things this was as opposed to using a namespace instead?
Are there advantages/disadvantages of one over the other</p>
<p>--------- Edit ----------</p>
<p>I'm sorry, I obviously should have pointed this out explicitly, as nobody has inferred it from the name of the class - which is "Defines". i.e. these constants are not associated with a particular class, there has been a class created specifically just to hold constants and nothing else, that is all the class Defines contains. </p>
<p>My question is not why should you place constants in a particular class, the question is is there any value in collecting dozens of them together and placing them <em>in a class</em> whose only purpose is to collect together constants, as opposed to collecting them together in a namespace, or just collecting them together in a header file specifically for that purpose etc. </p>
<p>(There is no currently existing namespace in the project therefore potential issues of polluting the namespace as mentioned in answers are not relevant in this case.)</p>
<p>----- 32nd edit -----------</p>
<p>and a follow up question ---
is placing
const char* Defines::StringN = "Somevalue" </p>
<p>in the .h file inefficient versus placing it in the .cpp file?</p>

2,389,702 | 2,389,703 | Specifiying keyword arguments with *args and **kws | <p>I've found a behavior in Python that has baffled and irritated me and I was wondering what I got wrong...</p>
<p>I have a function which should take an arbitrary number of arguments and keywords, but in addition should have some default-valued keywords that comprise it's actual interface:</p>
<pre><code>def foo(my_keyword0 = None, my_keyword1 = 'default', *args, **kws):
for argument in args:
print argument
</code></pre>
<p>The problem is that if I try calling <code>foo(1, 2, 3)</code> I'll only get the printout for 3 and the values 1 and 2 will override my keyword arguments.</p>
<p>On the other hand if I try moving my keywords after the <code>*args</code> or after the <code>**kws</code> it will cause a syntax error. The only solution I found to the problem was to extract the keyword arguments from <code>**kws</code> and setting default values to them:</p>
<pre><code>def foo(*args, **kws):
my_keyword0 = None if 'my_keyword0' not in kws else kws.pop('my_keyword0')
my_keyword0 = 'default' if 'my_keyword1' not in kws else kws.pop('my_keyword1')
for argument in args:
print argument
</code></pre>
<p>This is horrible both because it forces me to add pointless code and because the function signature becomes harder to understand - you have to actually read the functions code rather than just look at its interface.</p>
<p>What am I missing? isn't there some better way to do this?</p>

Lots of help here! I'm having an issue though that I am having a hard time fixing. I have a progress bar shown while the application attempts to download files from a networked computer. This works perfectly fine, however I need to update my UI incase an error occurs. I can't update the UI inside the thread and I want to update the UI from getRaceResultsHandler. Unfortunately it executes that code prior to the thread being completed. I have tried a few things with no luck. I have a code sample with my comments below if anyone can help.</p>
<pre><code>public void getRaceResultsHandler (View view) {
dialog = new ProgressDialog(this);
dialog.setCancelable(true);
dialog.setMessage("Attempting to transfer race files. Please wait...");
// Set progress style to spinner
dialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
// display the progressbar
dialog.show();
// create a thread for downloading the files
Thread background = new Thread (new Runnable() {
public void run() {
//The Code here to execute the file download from the networked computer....
//Dismiss the progress bar because the download is either completed or failed...
dialog.dismiss();
}
});
// start the background thread
background.start();
//All Other Code Goes here to update the UI. Shows either an error message or a success based on the results of the download.
//My problem is that this code executes before the background thread is completed. I need it to wait until the thread is completed.

3,285,085 | 3,285,086 | How do I know when a GLSurfaceView is fully initialized from the Activity? | <p>I have an Activity that contains several views. One of which is a GLSurfaceView. This GLSurfaceView displays pretty 3D effects based on what is selected in my Activity's other views (ListViews, EditTexts, etc). The issue I am having is that I don't know when my GLSurfaceView has been fully initialized from the Activity.</p>
<p>I began by simply attempting to pass my graphics data to my GLSurfaceView in my Activity's onCreate() method shortly after the setContentView() method. This worked fine on the emulator but on several devices this fails with null pointer exceptions from attempting to access objects that had not even been constructed yet. I assumed it was because my view had not been inflated yet and perhaps inflating views just takes longer on my devices.</p>
<p>I scattered some logging just to see the order of things and I found that my GLSurfaceView's onSurfaceCreated method is called well after the GLSurfaceView's onFinishInflate method.</p>
<p>So now I am looking for a good way to determine in my Activity when my GLSurfaceView's onSurfaceCreated method has been called so that I can safely tell my GLSurfaceView what to draw.</p>
