C++ MFC double to CString

Question

Sorry for my English.

I need to convert double value to CString, because i need to do AfxMessageBox(double_value);

I find this:

std::ostringstream ost;
ost << double_value;
std::cout << "As string: " << ost.str() << std::endl;
//AfxMessageBox(ost.str()); - Does not work.

How i can do this?

Answer 1

AfxMessageBox expects a CString object, so format the double into a CString and pass that:

CString str;
str.Format("As string: %g", double);
AfxMessageBox(str);

Edit: If you want the value displayed as an integer (no value after decimal point) then use this instead:

str.Format("As string: %d", (int)double);
