How to convert a TCHAR array to std::string?


How do I convert a TCHAR array to std::string (not to std::basic_string)?


Solution

  • TCHAR is just a typedef that, depending on your compilation configuration, either defaults to char or wchar_t.

    Standard Template Library supports both ASCII (with std::string) and wide character sets (with std::wstring). All you need to do is to typedef String as either std::string or std::wstring depending on your compilation configuration. To maintain flexibility you can use the following code:

    #ifndef UNICODE  
      typedef std::string String; 
    #else
      typedef std::wstring String; 
    #endif
    

    Now you may use String in your code and let the compiler handle the nasty parts. String will now have constructors that lets you convert TCHAR to std::string or std::wstring.
