[[UPDATE]] -> If I #include "Queue.cpp" in my program.cpp, it works just fine. This shouldn't be necessary, right? Hey all -- I'm using Visual Studio 2010 and having trouble linking a quick-and-dirty Queue implementation. I started with an empty Win32 Console Application, and all files are present in the project.

For some years that I've been using my own PHP template engine, which is not really "my own" as I saw it on a tutorial many years ago. However, I've refactored most of the code making it simpler and easier to use. I rarely make a PHP project without it. It's very basic and the class only has 3 methods, load, assign and render. The load ...

Currently we store report templates (word docs) as binary arrays within a dll in our C# solution. public readonly static byte[] audit_engagement_template = new byte[] {208,207,17,224,161,177,26,225,0,0,0,0,0,0,0,0,... Etc etc. Now this file has become HUGE and very unmanageable as Visual Studio starts using over 2.5Gb of memory whene...
I'm using an C++ "event" class that allowed one or two arguments in the to be called delegates. Lately I've added support for delegates that don't require arguments, however when I specialze the class to use no template arguments I'm still required to add <> afther the class definition. Example usage with one/two arguments: class Exam...
I'm trying to accomplish namespace NTL { typedef std::valarray vector; } through standard C++. I know it's not allowed, but I need a quick and easy way (without reimplementing all functions, operators, overloads, etc.) to get a template typedef. I am now doing a template class Vector which has a valarray as data member, but that ...
I've found this odd case of some code (below) doesn't compile under Visual Studio 2008 and produces an "error C2872: 'Ambiguity' : ambiguous symbol" on line 12. Removing the using namespace RequiredNamespace on the last line fixes the error, but I'd expect that putting using namespace at the end of a file should have no effect. It also...

Say you have a vector class that has a template length and type - i.e. vec<2,float>. These can also be nested - vec<2,vec<2,vec<2,float> > >, or vec<2,vec<2,float> >. You can calculate how deeply nested one of these vectors is like this: template<typename T> inline int depth(const T& t) { return 0; } template<int N, typename T> inline ...
