'cout' a 'CString'

I'm debugging some existing code that heavily uses CSstrings  and can't figure out how to do a simple 'cout' of a CSstring in a VS2005 console program. An older solution listed here does not work:

http://www.experts-exchange.com/Programming/Languages/CPP/Q_21887736.html?sfQueryTermInfo=1+cout+cstring

It says to cast like this:

CString blah("this is a CString");
cout << (LPCTSTR)blah << endl;

But that does not seem to work on Visual Studio 2005. It still outputs what looks like an address and not text. Here's some sample code:

#include <atlstr.h>
#include <iostream>
using namespace std;

void main (void)
{
      CString str("this is a CString");
      cout << (LPCTSTR)str << endl; // outputs numbers, not text
}

Actually the snippet

void main (void)
{
      CString str("this is a CString");
      cout << (LPCTSTR)str << endl;
}

should work fine - what do you get when using

void main (void)
{
      CString str("this is a CString");
      cout << (char*)(LPCTSTR)str << endl;
}

The following prints an 8 digit number.

void main (void)
{
      CString str("this is a CString");
      cout << (LPCTSTR)str << endl;
}

Adding the (char*) as follows only prints a 't'

void main (void)
{
      CString str("this is a CString");
      cout << (char*)(LPCTSTR)str << endl;
}

Ah, you are using UNICODE? Then, that should be

void main (void)
{
      CString str("this is a CString");
      wcout << (LPCTSTR)str << endl; // 'wcout' instead of 'cout'
}

bah...it was the VS2005 'feature' where it defaults to Unicode Char set in every new project. Changed it to 'not set' and now it prints fine. Thanks. =)
