Hi, I am wondering what is produced by the compiler when using non-virtual derivation: template< unsigned int D > class Point { int[D]; // No virtual function // ... }; class Point2 : public Point<2> {}; class Point3 : public Point<3> {}; Does the derivation here only imply compile-time checks? Or is there some other ove...

In drupal 6 I'm trying to execute a function on every page and output a different link based on what IP address someone is coming from. However, when I try this, it seems that the result is getting cached. I have tried this as a module and in template.php, but have not gotten results. What is the best approach to make sure this function ...
Hello all, I think I've run into a (possible) VC6 (I know. It's what we use.) compiler error, but am open to the fact that I've just missed something dumb. Given the following code (It's just an example!): #include <iostream> // Class with template member function: class SomeClass { public: SomeClass() {}; template<class T> T ge...

In my template the function call executes successfully and returns the .html() from the existing <select> list but renders it as text in th...

I would like to write a "versatile" class representing the general container storing pointers. Should I use public inheritance or containment? template <class T> class List : public std::vector <T *> { //... } Or template <class T> class List { private: std::vector <T *> items; //... } May some problems occur with abstract class...
I have a C++ application that executes test cases. It is possible that some test cases will depend on output from other test cases. All test cases implement a basic interface: /// base class for all test cases class ITest { public: virtual void Execute() = 0; }; Test cases that produce some object that may be useful to other tes...
Hi, I am having trouble getting to grips with programming using templates in C++. Consider the following files. C.h #ifndef _C_H #define _C_H template <class T> class C { public: C(); virtual ~C(); } #endif _C_H C.cpp #include "C.h" template <class T> C<T>::C() { } template <class T> C<T>::~C() { } I try instantia...
Possible Duplicate: C++ template gotchas Hi, I am just in to my second month on SO, and I have seen enough number of posts on SO related to several common issues with templates. Is it a good idea to make a small Wiki on this (sadly I don't know how to make one)? The idea is to provide a reference as definitive as this (GMan'...
Hallo! I would like to specialise only one of two template types. E.g. template <typename A, typename B> class X should have a special implementation for a single function X<float, sometype>::someFunc(). Sample code: main.h: #include <iostream> template <typename F, typename I> class B { public: void someFunc() { std...
I'm trying to make a function template that will accept two (or more) of the nested variadic class templates listed below, as arguments, and put them into another data structure that will accept different types (pair or tuple is what I'll most likely use). Here are the classes and subclasses, along with the usage of my function (the fun...

Why can't you pass literal strings in here? I made it work with a very slight workaround. template<const char* ptr> struct lols { lols() : i(ptr) {} std::string i; }; class file { public: static const char arg[]; }; decltype(file::arg) file::arg = __FILE__; // Getting the right type declaration for this was irritating, so I ...

Here's an image showing what I'm looking for: I could do this using some sort of master-deta...
I'm trying, in vain, to create a simple Django template tag to either show or hide a "delete" link next to a submitted comment on my site. In a nutshell, I want to pass the comment object to the template tag, determine if the currently logged in user is authorized to delete the comment and then either show or not show the link.
