How to convert WORD type to string in Visual C++

Question

Could anyone explain how to convert WORD to string in C++, please?

  typedef struct _appversion
    {
        WORD            wVersion;  
        CHAR            szDescription[DESCRIPTION_LEN+1];
    } APPVERSION;

    // Some code
    APPVERSION AppVersions;

    // At this point AppVersions structure is initialized properly.

    string wVersion;

    wVersion = AppVersions.wVersion; // Error

// Error    1   error C2668: 'std::to_string' : ambiguous call to overloaded function   
    wVersion = std::to_string((unsigned short)AppVersions.wVersion);

@Petesh I am trying your solution and getting this error `Error 1 error C2668: 'std::to_string' : ambiguous call to overloaded functio...` Any clue how to fix it? Thanks! — NoWar, Oct 08 '15 at 12:53

a WORD in Visual C++ context is a type-definition for unsigned short.

so you can use std::to_string for this task:

 wVersion = std::to_string(AppVersions.wVersion);

Edit: appearently Visual Studio 2010 doesn't support C++11 features completly, use std::stringstream instead:

std::stringstream stream;
stream <<AppVersions.wVersion;
wVersion  = stream.str();

make sure to include <sstream>

it compiles perfectly on my Visual Studio 2013, but I guess you can add explicit cast , e.g. `to_string((unsigned short)myWord))` – David Haim Oct 08 '15 at 12:52
also, make sure you include header, e.g. `#include ` – David Haim Oct 08 '15 at 12:53
I have `#include ` included. And adding explicit cast does not help. – NoWar Oct 08 '15 at 12:55
Done, please take a look – NoWar Oct 08 '15 at 13:05

are you using Visual Studio 2010? – David Haim Oct 08 '15 at 13:11

@Dimi you might try casting to a type that is directly supported by `to_string`, I'd try `int`. – Mark Ransom Oct 08 '15 at 13:18
