Hi All, I'm writing an NSString category that requires an NSNumberFormatter. I'm stuck between initing and releasing one every time my category is used to print a string in a certain way or initing the formatter in my app and passing it through. The NSNumberFormatter has a couple of config calls run on it first to make it work just ri...
An Example Suppose we have a text to write and could be converted to "uppercase or lowercase", and can be printed "at left, center or right". Specific case implementation (too many functions) writeInUpperCaseAndCentered(char *str){//..} writeInLowerCaseAndCentered(char *str){//..} writeInUpperCaseAndLeft(char *str){//..} and so on... ...

So I got a lot of responses from this site that global variables are bad and kill puppies. What if I use such variables like this: function get_stuff(){ global $stuff; if(!stuff) $stuff = 'candy'; return $stuff; } function screen_output(){ $stuff = get_stuff; echo $stuff; } does this make the code better than using 'global...
Global state is conventionally frowned upon. However, I think I can use it clientside to make my app simpler. I have an AJAX web app that sets up several values when the user logs in - user id, as well as some other information. This info does not change for the lifetime of the app. I also have a cache of data to minimize trips to the...

Say, suppose i have a variable user in $_POST as well as $_COOKIE, and if i use echo $_REQUEST['user'] then which would print. I tried it and i get th...
Is there any reason why I shouldn't do something like the following (to avoid using a hidden field to store the temporary information)? I'm using jQuery syntax for brevity but it's a general JavaScript question. function editComments() { window.currentComments = $('#commentsTextBox').val(); $('#commentsTextBox').removeAttr("read...
I have a MS C++ project (let's call it project A) that I am currently compiling as a static library (.lib). It defines a global variable foo. I have two other projects which compile separately (call them B and C, respectively) and each links the shared static library A in. Both B and C are dll's that end up loaded in the same process. I ...
Yes I know global variables is a bad practice, but ease up on that rule for this one :P My code: include('something.php'); //where $from is declared function myfunc() { global $from; echo "from(myfunc)=$from<br />"; ... } echo "from=$from<br />"; myfunc(); The result is: from=2010-05-01 from(myfunc)= What's going on?...

Hello, I have created a Variable called "myDBManager" in my AppDelegate: @interface myAppDelegate : NSObject <UIApplicationDelegate> { MyDBManager *myDBManager; } @property (nonatomic, retain) MyDBManager *myDBManager; @end which I use in most other classes as a global Variable holding all my critical application data. It gets o...
I'm using C (not C++) and I'm unsure how to avoid using global variables. I have a pretty decent grasp on C, its syntax, and how to write a basic application, but I'm not sure of the proper way to structure the program. How do really big applications avoid the use of global variables? I'm pretty sure there will always need to be at lea...
Hi, I'm using MVC2 and VS2010 developing a website and need to use Application State global values.

Example: Let, i need to trace timestamp and position of touch events (eg. touch start, end) on a layer. I can trace it using global variable or class variable of the class which imple...
What exactly is global data? This may seem like a very rudimentary question but the reason I'm asking is because I'm wondering has the term become stretched over time - i.e it dosn't just apply to data in the "Global" namespace (in c++) or a variable that is available in every scope. So, what do you consider to be global data? ...
I'm afraid this is a bit of an abstract question. I'm basically writing an iPhone game which revolves around a Pet, a bit like a tamagotchi for example. I've created a Pet object, which contains all the data relevant to the Pet's status. The rest of the program accesses the Pet's data and performs relevant actions. The pet is saved to ...

But, static means internal linkage and the variable can not be available outside the file scope i.e it should not be available to other object files. But, they still can be accessed to other files using declarations like...
