Thread: message box class

I am working on a class that is supposed to make it easier to put stuff into message boxes. I want it to work like std::cout so I can do something like this:

Messagebox<<somevariable<<"blah blah blah"<<4654;

But I can't figure out how to do that without having to call a function at the end to display the message box, i.e., I have to do this:

Messagebox<<somevariable<<"blah blah blah"<<4654;
Messagebox.Display();

Does anyone know how to do this without having to call some display function? Here's what I have so far:

Code:

class MsgBox
{
public:
	std::ostringstream & operator << (signed char & param){stream<<param;return stream;}
	std::ostringstream & operator << (unsigned char & param){stream<<param;return stream;}
	std::ostringstream & operator << (char & param){stream<<param;return stream;}
	std::ostringstream & operator << (short & param){stream<<param;return stream;}
	std::ostringstream & operator << (unsigned short & param){stream<<param;return stream;}
	std::ostringstream & operator << (int & param){stream<<param;return stream;}
	std::ostringstream & operator << (unsigned int & param){stream<<param;return stream;}
	std::ostringstream & operator << (long & param){stream<<param;return stream;}
	std::ostringstream & operator << (unsigned long & param){stream<<param;return stream;}
	std::ostringstream & operator << (float & param){stream<<param;return stream;}
	std::ostringstream & operator << (double & param){stream<<param;return stream;}
	std::ostringstream & operator << (long double & param){stream<<param;return stream;}
	void Display() {::MessageBox(NULL,stream.str().c_str(),"caption",MB_OK);}
protected:
	std::ostringstream stream;
};

Thank you for your input. Actually my idea was to set it up so you wouldn't have to write anything else. std::cout will still work even if you don't write anything at the end. I might implement your suggestion if I can't figure out how to do it the other way.
