Hi, I am busy coding a dll that supplies several functions to a host application. This application calls the dll dynamically, loading and freeing it after every function call. I have no control over the host app. I can only work with within the dll. Is there a way I can keep certain variables in memory so that I can reuse them within e...
I know how to do a global variable, but whenever I try to define a global variable with a random number function, xcode says "initializer element is not constant." The compiler doesn't want to make a variable from a random number because the random number function is not constant. How do I generate a random number and then use that s...
Hi, Here's a common, simple task: Read configuration settings from a configuration file, save the settings (e.g. as a hash) in an object, access this object from various objects that need to access the configuration parameters. I found this implementation for the ConfigFile class implementation and it works. My question is: what is the...

Hi there, I am using Eclipse to write some Java code and the naming convention that I am following uses an 'm' as a prefix to any member variables for a class. As soon as I write the member variables I like to go to Source -> Generate Getters and Setters. This generates the methods that I require. However, the method and parameter names...
I'm having some trouble compiling/linking a set of classes, several of them dealing with a common global variable. Basically, I declare and define a extern variable foo in class A and access/update it in classes B and C. The relevant code looks like this: A.h extern string foo; // declare it <=== compiler error "storage class sp...

Ok, so my PHP is, to say the least, horrible. I inherited an application and am having to fix errors in it from someone that wrote it over 7 years ago. When I run the page, there is no return, so I checked the logs to see the error and here is what i get: PHP Parse error: syntax error, unexpected '=', expecting ',' or ';' in /http...
How do I do this? My code is something like this: var number = null; function playSong(artist,title,song,id) { alert('old number was: '+[number]+''); var number = '10'; alert(''+[number]+''); } The first alert always returns 'old number was: ' and not 10. Shouldn't it return 10 on both alerts on the second function ca...

I'm working on some VBA scripts for an Excel worksheet, and I've created a module that contains a whole listing of mostly strings that store the name of each of my database fields. That way, if anyone modifies the database, they can update the VBA variable in the module, and then all my scripts, which reference the global variable instea...
We currently define a list of constants (mostly these correspond to enumerations we have defined in the business layer) at the top of a stored procedure like so: DECLARE @COLOR_RED INT = 1 DECLARE @COLOR_GREEN INT = 2 DECLARE @COLOR_BLUE INT = 3 But these often get repeated for many stored procedures so there is a lot of duplication. ...
I am integrating third party code into the web application I am writing in Zend Framework. The code I want to integrate declares variables as global. It works on its own, but not when I include it within Zend Framework. Initially I suspected that there is something in Zend Framework that is disabling the declaration of global variables...

Hi, I'm using static initialisation to ease the process of registering some classes with a factory in C++. Unfortunately, I think the compiler is optimising out the 'unused' objects which are meant to do the useful work in their constructors. Is there any way to tell the compiler not to optimise out a global variable? class SomeClass {...
