I am reading $digit from infile and want to print it to outfile. But the Perl script is giving an error saying 'Global symbol "$digit" requires explicit package name'. But, if I do declare it globally , $digit='', then the this value is printed to the outfile instead of the value extracted/read from infile. Any suggestions as to what sho...
Hello all, I am a newbie in R programming. Though I am poking into the manuals, I also wanted to ask the community "How can we set global variables inside a function?" Any pointers will help. Question-2: Regarding plotting, I am using plotting multiple graphs in a single sheet, and to differentiate each one of them, I want to add tit...
I'm used to thinking of all initialization of globals/static-class-members as happening before the first line of main(). But I recently read somewhere that the standard allows initialization to happen later to "assist with dynamic loading of modules." I could see this being true when dynamic linking: I wouldn't expect a global initialize...
Is there any way to declare/define global/static objects of managed types ? ...
Hi, I know this must be an age-old, tired question, but I cant seem to find anything thru my trusty friend (aka Google). I have a .net 3.5 c# winforms app, that presents a user with a login form on application startup. After a successful login, I want to run off to the DB, pull in some user-specific data and hold them (in properties) ...
Hi, I've been noticing static classes getting a lot of bad rep on SO in regards to being used to store global information. (And global variables being scorned upon in general) I'd just like to know what a good alternative is for my example below... I'm developing a WPF app, and many views of the data retrieved from my db are filtered b...
In the type of embedded programming I'm getting into, determinism and transparency of the running code are highly valued. What I mean by transparency is, for instance, being able to look at arbitrary sections of memory and know what variable is stored there. So, as I'm sure embedded programmers expect, new is to be avoided if at all pos...
I thought I had this mess sorted out in my head but for some odd reason its not working. If you declare a variable outside of a function / scope and refer to it without the var inside a function then it changes the variable declared previously... right? however, the first alert returns the correct price, but the second (last) alert ret...
I am declaring an array of NSString* in a header file of a class. PolygonShape.h NSString* POLYGON_NAMES[] = {@"Invalid Polygon", @"Monogon", ...}; Now I am using this in PolyginShape.m as follows: - (NSString*) name { return (POLYGON_NAMES [self.numberOfSides]); } numberOfSides is an iVar which will indicate the index at which the...
Hello, I would like to know how can I create a global variable type NSArray that i can use (write in/read data) from any class from y app. At the moment i'm using NSUserDefaults, but I don't think this is the best option, because i'm saving one NSArray quite big. Thanks. ...

i have a problem with global variables in a c++ shared library project. my library has to be working as a standard g++ shared library (.so) as well as a dll. i did this by creating files libiup_dll.cpp and libiup_dll.h, where i have something like #ifdef BUILD_DLL // code for the dll: wrapper functions around the classes in my shared l...
I am using a variable/propery of my application delegate as a global. (I don't want to deal with a singleton class.) I am trying to write a #define statement in my Application Delegate class. If I type: [UIApplication sharedApplication] in my app delegate class, code hinting does not recognize sharedApplication. But if I type th...
Hi i have a little collection of classes some of which should be globally accessible. I found something similar in Zend_Registry, but reading its code i cant understand how a call to a static function could return an initialized instance of a class... i need to do something like: <?php //index.php $obj = new myUsefulObject(); $obj->lo...

I am currently working on a website that will have a high volume of traffic on it. The website has only 4-5 pages on it but I need to pass values selected on page 1 over to page 2 where more values are stored and so on until the user gets to page 5 where all values are passed to a third party system using XML. Currently I use a dictiona...
I want to define a constant that should be available in all of the submodules of a package. I've thought that the best place would be in in the __init__.py file of the root package. But I don't know how to do this. Suppose I have a few subpackages and each with several modules. How can I access that variable from these modules? Of cours...
Hi, I'm building an app, and I need the wisdom of the SO community on a design issue. In my application, there needs to be EXACTLY one instance of the class UiConnectionList, UiReader and UiNotifier. Now, I have figured two ways to do this: Method 1: Each file has a global instance of that class in the header file itself. Method 2:...
