sample code can't be compiled, why?

EDN Admin · Mar 22, 2008

i recently installed visual studio 2005 and wanted to run a sample c++ code at:
<a title="http://msdn2.microsoft.com/en-us/library/ms235631(VS.80).aspx http://msdn2.microsoft.com/en-us/library/ms235631(VS.80).aspx http://msdn2.microsoft.com/en-us/library/ms235631(VS.80).aspx
segment "Converting from wchar_t *"
code as follow:


#include <stdlib.h>
#include <string>

#include "atlbase.h"
#include "atlstr.h"
#include "comutil.h"

using namespace std;
using namespace System;

int main()
{
 wchar_t *orig = L"Hello, World!";
 wcout << orig << L" (wchar_t *)" << endl;

 // Convert to a char*
 size_t origsize = wcslen(orig) + 1;
 const size_t newsize = 100;
 size_t convertedChars = 0;
 char nstring[newsize];
 wcstombs_s(&convertedChars, nstring, origsize, orig, _TRUNCATE);
 strcat_s(nstring, " (char *)");
 cout << nstring << endl;

 // Convert to a _bstr_t
 _bstr_t bstrt(orig);
 bstrt += " (_bstr_t)";
 cout << bstrt << endl;

 // Convert to a CComBSTR
 CComBSTR ccombstr(orig);
 if (ccombstr.Append(L" (CComBSTR)") == S_OK)
 {
 CW2A printstr(ccombstr);
 cout << printstr << endl;
 }

 // Convert to a CString
 CString cstring(orig);
 cstring += " (CString)";
 cout << cstring << endl;

 // Convert to a basic_string
 wstring basicstring(orig);
 basicstring += L" (basic_string)";
 wcout << basicstring << endl;

 // Convert to a System:<img alt="Tongue Tied" src="http://forums.microsoft.com/MSDN/emoticons/emotion-7.gif tring
 String ^systemstring = gcnew String(orig);
 systemstring += " (System:<img alt="Tongue Tied" src="http://forums.microsoft.com/MSDN/emoticons/emotion-7.gif tring)";
 Console::WriteLine("{0}", systemstring);
 delete systemstring;
}

the compiler reports error when i compiled this code, saying error LNK2028, 2019 etc

 I just want to ask: How should i create the project if i want to run it without any issues. Detailed project settings? 

PS. i tried Win32 Console Application and CLR Console Application, but it doesnt work at all<img src="http://forums.microsoft.com/MSDN/WebResource.axd?d=NySzF1eivP_rMoc50GQJzcvS4MHMOEKwYrCIgDtzuzlw7GsNki3H_INlfYaLgkxFSSG0MZbJ1z6uFFjZvu3APg2&t=633337194230757564
