    MFC-like free CString class?

    Hi there,

    I'm looking for a free MFC-like CString class which contains the "Format"-method as well. It should be platform independent...

    I'm already searching the net for hours and I only find smart statements like "there are tons of free string classes out there" but no suitable code.

    Thanks in advance for your help!

    I have a similar problem: I work with a class called _bstr_t in COM and the ubiquitous CString for MFC, and I commonly mix them up (I have to do this as MFC does like it's own CString for some functions and working with BSTRs can be nasty), but when I can get away with it I use the standard library.

    You can use a std::string and a std::stringstream with no problem, together they can easily manage your usual calls to Format. Also, I often typedef them so I can use them with UNICODE.

    Code:
    #include <windows.h>
    #include <tchar.h>
    
    #include <string>
    #include <sstream>
    
    //undefine both of these for UNICODE
    //#define UNICODE
    //#define _UNICODE
    
    namespace TSTD
    {
    	typedef std::basic_string<TCHAR> string;
    	typedef std::basic_stringstream<TCHAR> stringstream;
    }
    
    
    int main()
    {
    	TSTD::stringstream ss;
    	TSTD::string str = _T("Hello World");
    
    	ss << _T("This is an int - ") << 10000 << std::endl;
    	ss << _T("This is a floating point - ") << 5.69 << std::endl;
    	ss << _T("This is a string - \"") << str << _T("\"");;
    
    	MessageBox(HWND_DESKTOP,ss.str().c_str(),_T(""),MB_OK);	
    }

    Fordy, if you uncomment the UNICODE lines nothing will happen, because you've already included tchar.h and windows.h.
    We get the point though.
