TextOut in VC++

Hi Experts,

This is actually a continuous question of :
https://www.experts-exchange.com/questions/21170689/write-words-on-the-screen.html

I tried to use TextOut to print a string on the screen :
------------------------------------
string mystring ;
mystring = "Hello" ;
TextOut(mdc, x, y , _T(mystring), 4);
---------------------------------------------------
but it didn't work : I got the errors :
:\Program Files\Microsoft Visual Studio\MyProjects\MyMap\MyMap.cpp(485) : error C2664: 'TextOutA' : cannot convert parameter 4 from 'class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >' to 'const char *'
No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called
------------------------------------
Does anyone know what I might have missed and how to fix it ??? thanks !!!

TextOut(mdc, x, y , mystring.c_str(), 4);

In a MFC project you should consider using CString rather than std::string as you wouldn't have compatibility problems like that above:

CString mystring ;
mystring = "Hello" ;
TextOut(mdc, x, y , _T(mystring), 4); // no problems with CString

There is a CString::operator LPCTSTR() that can convert any CString to a LPCTSTR (const TCHAR*), but there isn't an equivalent function in std::string.
