In here, T can be from the class CMesh * or CSkinnedMesh *, both have signature of GetAnimController
This maybe a flaw in my design... But I want Create to accept any kinds of meshes.
Should I create an interface or abstract class above all of those?
I have added an IMesh class that every derived classes has to have the needed interface.
But since then, I have another question, I feel that it is very cumbersome to include a template argument in every class/prototype that is associated with CObject
Say bool CreatePlanesFromObject(CObject *pObject, D3DXPLANE *pPlanes); Requires me to do this template<class T> bool CreatePlanesFromObject(CObject<T>* pObject, D3DXPLANE* pPlanes);
Any ways I can omit the template argument, because it doesn't make sense to know the Mesh type in other classes...
I have a question similar to the one here: [URL] .....
The main difference is I would like to pass a method of derived class as a parameter to some other method in its template base class.
template <typename BaseType> class Base { public: typedef void (Base::*Callback)(int A);
[Code] .....
The above is an example which does not compile. My compiler complains that the two BaseMethod() calls in DerivedMethod() are invalid uses of non-static member function.
Is this not possible to do, or is my syntax simply wrong? All I want is to be able to pass as an an argument to a method in the base class from the derived class some callback as a variable for the base class to invoke later.
I have been experimenting with variadic templates with the aim of caching a call to a class method by storing away the object pointer, method pointer and parameters. I've actually had some reasonable success but have now hit a stumbling block. I now wish to wrap my parameters in a simple template class when I cache them. My success is as follows:
Using variadic template functions to store these pointers and paremeters;
I'm able to pass a method pointer and unwrapped parametersI'm able to pass wrapped parameters on their own.I'm NOT able to pass a method pointer and wrapped parameters I set up a little prototype project to demonstrate the issue and added comments above the function calls to indicate the compilation results. Here is the code:
Code: #include "stdafx.h" ////////////////////////////////////////////////// // Basic class with a simple method ////////////////////////////////////////////////// class MyClass { public: char Method( int i, float f ) { return 'A';
[code]....
But I'm convinced it should take three arguments, the method pointer and two wrapped parameters. Visual studio even suggested it should as shown below:
I'm trying to implement a simple template array class, but when i came into the operator< i actually have to use a template :
my code is something like :
template<typename _Type, std::size_t _Size> class array { public :
[Code] ......
but i am having an error of shadows template param 'class _Type' is it w/ the name conflict between the array template parameter and the function template parameter ?

I have a generic template class with another template in one of its types. Now I want to specialize one of its methods for a particular (template) class, which leads to a compile error, however.
GCC ends with: :35:27: error: type/value mismatch at argument 2 in template parameter list for ‘template<class Type, template<class> class O> class Foo’ :35:27: error: expected a class template, got ‘Obj2<Type>’
What is wrong with the specialization? Can it even be achieved and how (if so)?
how I want the code to look. Only problem is it doesn't work (Line 11). I have some experience with templates but I'm not a pro.
Basically I want the "Channels<3>" to be a type that I can use to specify a Cable with similar to vector<float/int> it would be Cable<Channels<2 or 3>>.
What have I messed up with the syntax?
#include <iostream> #include <vector> using namespace std;
I need to create a method (constructor) to initialize a bigint to an int value you provide [0, maxint].
Example: bigint(128).
Here is my class:
#ifndef BIGINT_H #define BIGINT_H const int MAXINT = 500; class bigint{ public: bigint();
[Code] ....
So if the user inputs (4123 for example). How would I make 4 in size[0], 1 in size [1], 2 in size [2], etc. I don't even know where to start. Im guessing I would start with a for loop. It has to be an integer. I cant use a string yet.
I am wanting to separate the logic from the visual, but I'm having problems when calling the method that controls the actions of the progress bar timer.

I am getting error at the assertion points when i call to the class as follows:
For my data-structures class, I am attempting to create a binary search tree template to be used to create an AVL tree. I've written a Generic_Tree template for the BST to inherit from, and before I jump into implementing the AVL tree I'm testing the BST member functions. Everything was compiling fine until I added the BST insert() function. Now, I'm getting the following error message from my linker:
undefined reference to 'BST<void>::insert(int, void*)'
Basically am trying to reference a method in a my Form1 class into another class. So far I have tried multiple different methods to try and access the method but have not managed it so far. Both classes use the same namespace. The part of my form class that I am using are as follows:
public class Form1 : Form { IContainer components = null; private ButtonPanelThread p1, p3, p4;
When the below is done, does it call the constroctor only, and if yes, constructors do not have return types so how does it work? is there anything behind the scene?
wxAddHandler(new wxPNG_HANDLER); and sf::RenderWindow(sf::VideoMode(...),...);
