C / C++ / MFC

//Unicode build
CString sz = L"Hello";
const std::wstring str = sz;

//MBCS build
CStringA sz = "Hello";
const std::string str = sz;

'fun1' : cannot convert parameter 1 from 'const std::wstring' to 'const std::string &'

and fun1 is like this

std::string fun1 (std::string const& s);

Or use std::tstring[^] and not have to worry about it at all.

#if defined(UNICODE)
typedef std::wstring    STRING

Is there some "clear" and nice way of doing this?

1. Parameters

struct PARAMS
{
    int Val1;
    int Val2;
};

2. Thread

DWORD __stdcall Thread(LPVOID lpParam)
{
    MSG Message;
    while(true)
    {
	::GetMessage(&Message, NULL,  0, 0);
        switch(Message.message)
        {
            case SOMETHING:
            // .......... do something
            // Message.lParam will contain a pointer
            PARAMS *p = (PARAMS*)Message.lParam;
        }
    }
}

3. Notification

PARAMS *p = new PARAMS;
p->Val1 = ...
::PostThreadMessage(m_dwMyThread, SOMETHING, NULL, (LPARAM)p);

Please let me know which version of MS-VC6.0 will support this.
