An example of what I'm working with is as such: [code] <?xml version="1.0"?> <postRoot xml:lang="EN"> <post type="comment" date="January 1, 1970"> <user>athlon32</user> <content>Hello World</content> </post> </postRoot> [/code] Now, I've … |

| | I'm have a small confusion, and i need a little clarification; when you make something on the heap, like this: [code=C++]int *somePointer = NULL; somePointer = new int;[/code] an int is created on the heap right? This would be the equivalent of doing something like...: [code=C++]int x;[/code] ...directly on the …  |
| | I'm following a tutorial on Win32, and as I compile the examples, I'm also kinda messing with the code to experiment with different concepts.
