I am looking as a new file format specification and the specification says the file can be either xml based or a zip file containing an xml file and other files. The file extension is the same in both cases. What ways could I test the file to decide if it needs decompressing or just reading? ...
I haven't used C very much in the last few years. When I read this question today I came across some C syntax which I wasn't familiar with. Apparently in C99 the following syntax is valid: void foo(int n) { int values[n]; //Declare a variable length array } This seems like a pretty useful feature, does anyone now if there was eve...
Our company wants to transform our current user interface to a web client. We are considering to use Microsoft's Silverlight for this, but it will need to communicate with our legacy C++ server application (native C++, not C++/CLI). I am wondering whether it would be feasible to write such an IPC library by hand, our otherwise whether th...

I'm currently working on a project in which I'd like to define a generic 'collection' interface that may be implemented in different ways. The collection interface should specify that the collection has methods that return iterators by value. Using classes that wrap pointers I came up with the following (greatly simplified): Collection....

Core of the problem: I receive "(0x80070002) The system cannot find the file specified" for roughly 8 to 9 seconds before it can open it successfully. In a nutshell, we have two com components.

I am implementing a client/server application where video streaming occurs between two computers (in one direction). I would like to have the server publish an SDP file when it starts streaming. The client would then be able to download this SDP file and use it to get the stream. In order to implement this it seems I need to include a RT...
// -------------------------------------------------------------------- UPDATE: I messed up. I left a call directly to openfeint in my AppDelegate->onApplicationWillResignActive which was causing the compiler C++ error. My Appologies, the singleton does work should anyone be thinking of trying the same thing. Just be sure to include t...
I need to call a method that expects a function pointer, but what I really want to pass to it is a functor. Here's an example of what I'm trying to do: #include <iostream> #include "boost/function.hpp" typedef int (*myAdder)(int); int adderFunction(int y) { return(2 + y); } class adderClass { public: adderClass(int x) : _x(x) ...

union members may not have destructors or constructors. So I can't template the following class Foo on my own MyClass if MyClass has a constructor: template<class T> struct Foo { T val; Foo(T val_) : val(val_) {} size_t hash() const { union {T f; size_t s;} u = { val }; return u.s; } }; struct MyClass { bool a; doubl...
Ok so let's say we have a linked list of characters with a head pointer. How can I create a loop to enter a string of characters into the linked list? My problem is when I think of head and head->next and head->next->next . . . it only seems natural to use a recursive function to set the characters at each node. ...
