I have a database class, which an instance is declared in the main index.php as $db = new Database(); Is there a way for the $db variable to be globally recognized in all other classes without having to declare global $db; in the constructor of each class? ...
What does it do, in Python 3.0? There's no documentation on the official Python website and help("nonlocal") does not work, either. ...
What I am trying to do is have a separate PHP file containing settings for the website, and then having other pages include this file and execute code according to the settings. However, whenever I use global to reference these variables inside a class, the variables are empty. For example: settings.php: <?php $setting1 = 'on'; $settin...
Hi, I'm working on some C++ code and I've run into a question which has been nagging me for a while... Assuming I'm compiling with GCC on a Linux host for an ELF target, where are global static constructors and destructors called? I've heard there's a function _init in crtbegin.o, and a function _fini in crtend.o. Are these called by c...
I'm programming an application consisting of three usercontrols in an main window. In one of the usercontrols, there's a slider that needs to be controllable by keyboard input. The left arrow should decrease value, right button increase and so on. I have this work, but only when the slider has focus. If some other control has focus, I c...

Basically i am playing with a plugin that allows future-dated posts on archive pages. My question is broader than this specific functionality, but everyone likes some context. I have my head around many of the plugin development concepts, but must be missing something very basic. I can successfully rewrite a query that gives me the res...
Say I have a struct like the following ... typedef struct { int WheelCount; double MaxSpeed; } Vehicle; ... and I have a global variable of this type (I'm well aware of the pitfalls of globals, this is for an embedded system, which I didn't design, and for which they're an unfortunate but necessary evil.) Is it faster to access t...
I'm trying to make a program like AutoHotKey, but with a graphical interface. I'm using java.awt.Robot Now I want to make the code for checking the state from a key (In AHK: getKeyState) Of course somthing like a KeyListener without having focus. I read already something with JNI and C++, but.... I can't find some information. Can someb...
In C, declaring a variable static in the global scope makes it a global variable. Is this global variable shared among threads or is it allocated per thread? Update: If they are shared among threads, what is an easy way to make globals in a preexisting library unique to a thread/non-shared? Update2: Basically, I need to use a preexisti...
Here are the problem scripts: This is from the HTML file: <script type="text/javascript"> var devices_record = "some string"; </script> <script type="text/javascript" src="/js/foo.js"></script> This is from foo.js: function bar () { devices_record = "assign new string"; } The error report by HttpFox is that devices_ record...
On analyzing my 4 days log of verbose, I get this Number of Global Garbage Collection: 0 Number of Scavenger Garbage Collection: 492 that's all? My tenured area is continuously full and memory leak is occurring. No GC attempt has been made to clear the memory Nursery area is always almost free/ empty (reason for low scavenger calls) ...
It's my understanding that all three of these lines below should return an ARRAY with 2 results in it. Yet RegExp will only return 1 result no matter how many times the regex repeats in the string. Can some one explain why? And perhaps suggest how I can get RegExp to give me global results? //INTPUT: console.log(new RegExp("New Yo...
The discussion around global variables and their misuse seems to hold a a certain dogmatic tone to it. I am not here to dispute the "globals are bad" concept as it makes sense to me why they are bad. However I was wondering if people had some interesting code snippets that demonstrate exactly how to effectively refactor higher scoped var...
Is there any way to catch Javascript errors globally across the web application by writing some code in the master page? ...
I currently work in an environment where reports must be emailed to users as a PowerSoft file. There is a global PowerBuilder function which is used on a computed column my datawindow. This datawindow becomes the final psr report. In my testing the function is resolved fine, when run live. However, when the user runs the report, it se...
Is there a way to attach a loading gif, using Jquery, anytime any image on my site within a certain div is loading? I would like for it to be a global function, the only way I can seem to figure to do this is using jquery to call a certain link, and then load the loading.gif but that won't work in my situation… Index HTML: <div id="con...
I've inherited a project that stores various parameters either in a config file, the registry and a database. Whoever needs one of these parameters just reads (and in some cases writes) it directly from the store. This, or course, is stupid, so my first thought was to refactor the existing code so that the client doesn't know where the p...

Hello all, I'm having a spot of trouble getting my python classes to work within the python console. I want to automatically import all of my classes into the global namespace so I can use them without any prefix.module.names. Here's what I've got so far... projectname/ |-__init__.py | |-main_stuff/ |-__init__.py |-main1.py |-ma...
