However, when I run the C# program it complains: Unhandled Exception: System.IO.FileNotFoundException...
I've been evaluating various smart pointer implementations (wow, there are a LOT out there) and it seems to me that most of them can be categorized into two broad classifications: 1) This category uses inheritance on the objects referenced so that they have reference counts and usually up() and down() (or their equivalents) implemented....

I have a class (class A) that is designed to be inherited by other classes written by other people. I also have another class (class B), that also inherits from A. B has to access some A's member functions that shouldn't be accessed by other inheriting classes. So, these A's member functions should be public for B, but private for othe...
I have an array of unsigned numbers, called dataArray (actually in the program I am trying to figure out, they are entered as hexadecimal numbers, but I don't think that's important). I have another variable of type unsigned char, called c. What does this do? unsigned int dataArray[]={1,2,3,4,5}; unsigned char c; x=c^ (dataArray)[i]; ...

We'd like to support some hardware that has recently been discontinued. The driver for the hardware is a plain 32-bit C DLL. We don't have the source code, and (for legal reasons) are not interested in decompiling or reverse engineering the driver. The hardware sends tons of data quickly, so the communication protocol needs to be pretty...
I'm working on a project using C++, Boost, and Qt. I understand how to compress single files and bytestreams using, for example, the qCompress() function in Qt. How do I zip a directory of multiple files, including subdirectories? I am looking for a cross-platform (Mac, Win, Linux) solution; I'd prefer not to fire off a bunch of new pr...
