In this tutorial we will show you how to work with c++ template libraries using vc++ mfc template libraries. After viewing the video tutorial, download the source code and try to modify the code so as to get a feel of what is learned in this video tutorial.


Program 
// TemplateExample.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
/*
This program illustrates the use of MFC Template calss(CArray<data type,data type>) and string 
Handling(CString) classes, writing your own class (CStudent),
Manipulating an array of objects(CArray<>) using template classes

  Included these fies in stdafx.h

#include <stdio.h>
#include <iostream.h>
#include <afx.h>
#include <afxtempl.h>

  Note:

  if you are getting some sort of link error in any of your program

  linking...
nafxcwd.lib(thrdcore.obj) : error LNK2001: unresolved external symbol __endthreadex
nafxcwd.lib(thrdcore.obj) : error LNK2001: unresolved external symbol __beginthreadex
Debug/TemplateExample.exe : fatal error LNK1120: 2 unresolved externals

  Please open Project->settings menu,

  after that use this open

  "MFC as a static link library" in the combo box provided.
