C / C++ / MFC

// example using the STL and streams
double dValue = 99.9;
std::stringstream sstr;
sstr << _T("This is some string with a double: ") << dValue << std::endl;

// example using the CTR
double dValue = 99.9;
TCHAR szBuf[1024] = {0};
_sntprintf(szBuf, 1023, _T("This is some string with a double: %f", dValue);

The syntax looks more clean
I remember now a nice CString replacement written by another CPian: CStdString[^]. You can use this class instead of the MFC CString without too much hassle.
