Let's suppose I have a struct like this: struct my_struct { int a; int b; } I have a function which should set a new value for either "a" or "b". This function also requires to specify which variable to set. A typical example would be like this: void f(int which, my_struct* s, int new_value) { if(which == 0) s->a = new_va...

ParentClass<T>::member instead of just member But still I have a lot of old code that does not respect this. Adding using ParentClass<T>::member for ea...

I have noticed that a lot of mediawiki-based websites use such templates as Robelbox, Ambox etc. Where can I get them and how should they be installed? ...
I have a class that my client uses to Get() a packet. The packet contains a std::vector whose type is not known until the packet is generated internally in my Interface class (in this example, it depends on the Packet::type variable). I was wondering if template could be used for this since the Packet class is just a generic class whose...

I'm in the process of adding ASP.NET MVC to a WebForms app. One of the neat features of an ASP.NET MVC solution that you create from scratch is that a right click on the solution explorer and Add > New Item... will give a list of templates which include the MVC templates. However, in a WebForms app these templates don't appear. I though...

I tried the obvious case: template<class T, T* T::*nextptr> T* Queue<T, nextptr>::*...

So, wouldn't something like this be better: template<class AtomT, class BioT, class ChemT> class Foo {}; I also tend to ...

I want to have a conditional of the form: {continue}click to continue{/continue} So if it's possible to continue, the text "click to continue" will display, otherwise, don't display this whole...

I want the template to show slightly different content for each of these two classes of pages. The @login_required view decorator is always used on views which on...

I took a simple template like template <typename T> class Argument { public: int size; int type; T data; }; and with some overloaded addMessage (int value) { Argument<int> *a = new Argument<int>; vec.push_back(a); } (same for string and so ...
I'm a blitz++ newbie.

I'm looking for a template engine for .NET/C# to generate email notifications in my application. I read about NVelocity in the past and think it would fit my needs, but it seems this project is dead. Would you still recommended to use NVelocity for that purpose or can you suggest any alternatives? Note: I found some other templating en...
