//    If you find any bugs in this code, please let me know:
//
//        jmoleary@earthlink.net
//        http://www.joeo.net/stdstring.htm (a bit outdated)
//
//      The latest version of this code should always be available at the
//      following link:

//
//
//  REMARKS:
//    This header file declares the CStdStr template.  This template derives
//    the Standard C++ Library basic_string<> template and add to it the
//    the following conveniences:
//      - The full MFC CString set of functions (including implicit cast)
//      - writing to/reading from COM IStream interfaces
//      - Functional objects for use in STL algorithms
//
//    From this template, we intstantiate two classes:  CStdStringA and
//    CStdStringW.  The name "CStdString" is just a #define of one of these,
//    based upone the UNICODE macro setting
//
//    This header also declares our own version of the MFC/ATL UNICODE-MBCS
//    conversion macros.  Our version looks exactly like the Microsoft's to
//    facilitate portability.
//
//  NOTE:
//    If you you use this in an MFC or ATL build, you should include either
//    afx.h or atlbase.h first, as appropriate.
//
//  PEOPLE WHO HAVE CONTRIBUTED TO THIS CLASS:
//
//    Several people have helped me iron out problems and othewise improve
//    this class.  OK, this is a long list but in my own defense, this code
//    has undergone two major rewrites.  Many of the improvements became
//    necessary after I rewrote the code as a template.  Others helped me
//    improve the CString facade.

//
//  REVISION HISTORY
//
//    2005-JAN-10 - Thanks to Don Beusee for pointing out the danger in mapping
//          length-checked formatting functions to non-length-checked
//          CRT equivalents.  Also thanks to him for motivating me to
//          optimize my implementation of Replace()
//
//    2004-APR-22 - A big, big thank you to "MKingman" (whoever you are) for
//          finally spotting a silly little error in StdCodeCvt that
//          has been causing me (and users of CStdString) problems for
//          years in some relatively rare conversions.  I had reversed
//          two length arguments.
//
//    2003-NOV-24 - Thanks to a bunch of people for helping me clean up many
//          compiler warnings (and yes, even a couple of actual compiler
//          errors).  These include Henk Demper for figuring out how
//          to make the Intellisense work on with CStdString on VC6,
//          something I was never able to do.  Greg Marr pointed out
//          a compiler warning about an unreferenced symbol and a
//          problem with my version of Load in MFC builds.  Bill
//          Carducci took a lot of time with me to help me figure out
//          why some implementations of the Standard C++ Library were
//          returning error codes for apparently successful conversions
//          between ASCII and UNICODE.  Finally thanks to Brian Groose
//          for helping me fix compiler signed unsigned warnings in
//          several functions.
//
//    2003-JUL-10 - Thanks to Charles Godwin for making me realize my 'FmtArg'
//          fixes had inadvertently broken the DLL-export code (which is
//                  normally commented out.  I had to move it up higher.  Also
//          this helped me catch a bug in ssicoll that would prevent
//                  compilation, otherwise.
//
//    2003-MAR-14 - Thanks to Jakko Van Hunen for pointing out a copy-and-paste
//                  bug in one of the overloads of FmtArg.
//
//    2003-MAR-10 - Thanks to Ronny Schulz for (twice!) sending me some changes
//                  to help CStdString build on SGI and for pointing out an
//                  error in placement of my preprocessor macros for ssfmtmsg.
//
//    2002-NOV-26 - Thanks to Bagira for pointing out that my implementation of
//                  SpanExcluding was not properly handling the case in which
//                  the string did NOT contain any of the given characters
//
//    2002-OCT-21 - Many thanks to Paul DeMarco who was invaluable in helping me
//                  get this code working with Borland's free compiler as well
//                  as the Dev-C++ compiler (available free at SourceForge).
//
//    2002-SEP-13 - Thanks to Glen Maynard who helped me get rid of some loud
//                  but harmless warnings that were showing up on g++.  Glen
//                  also pointed out that some pre-declarations of FmtArg<>
//                  specializations were unnecessary (and no good on G++)
//
//    2002-JUN-26 - Thanks to Arnt Witteveen for pointing out that I was using
//                  static_cast<> in a place in which I should have been using
//                  reinterpret_cast<> (the ctor for unsigned char strings).
//                  That's what happens when I don't unit-test properly!
//                  Arnt also noticed that CString was silently correcting the
//                  'nCount' argument to Left() and Right() where CStdString was
//                  not (and crashing if it was bad).  That is also now fixed!
//
//    2002-FEB-25 - Thanks to Tim Dowty for pointing out (and giving me the fix
//          for) a conversion problem with non-ASCII MBCS characters.
//          CStdString is now used in my favorite commercial MP3 player!
//
//    2001-DEC-06 - Thanks to Wang Haifeng for spotting a problem in one of the
//          assignment operators (for _bstr_t) that would cause compiler
//          errors when refcounting protection was turned off.
//
//    2001-NOV-27 - Remove calls to operator!= which involve reverse_iterators
//          due to a conflict with the rel_ops operator!=.  Thanks to
//          John James for pointing this out.
//
//    2001-OCT-29 - Added a minor range checking fix for the Mid function to
//          make it as forgiving as CString's version is.  Thanks to
//          Igor Kholodov for noticing this.
//          - Added a specialization of std::swap for CStdString.  Thanks
//          to Mike Crusader for suggesting this!  It's commented out
//          because you're not supposed to inject your own code into the
//          'std' namespace.  But if you don't care about that, it's
//          there if you want it
//          - Thanks to Jason Mills for catching a case where CString was
//          more forgiving in the Delete() function than I was.
//
//    2001-JUN-06 - I was violating the Standard name lookup rules stated
//          in [14.6.2(3)].  None of the compilers I've tried so
//          far apparently caught this but HP-UX aCC 3.30 did.  The
//          fix was to add 'this->' prefixes in many places.
//          Thanks to Farrokh Nejadlotfi for this!
//
//    2001-APR-27 - StreamLoad was calculating the number of BYTES in one
//          case, not characters.  Thanks to Pablo Presedo for this.
//
//    2001-FEB-23 - Replace() had a bug which caused infinite loops if the
//          source string was empty.  Fixed thanks to Eric Nitzsche.
//
//    2001-FEB-23 - Scott Hathaway was a huge help in providing me with the
//          ability to build CStdString on Sun Unix systems.  He
//          sent me detailed build reports about what works and what
//          does not.  If CStdString compiles on your Unix box, you
//          can thank Scott for it.
//
//    2000-DEC-29 - Joldakowski noticed one overload of Insert failed to do a
//          range check as CString's does.  Now fixed -- thanks!
//
//    2000-NOV-07 - Aaron pointed out that I was calling static member
//          functions of char_traits via a temporary.  This was not
//          technically wrong, but it was unnecessary and caused
//          problems for poor old buggy VC5.  Thanks Aaron!
//
//    2000-JUL-11 - Joe Woodbury noted that the CString::Find docs don't match
//          what the CString::Find code really ends up doing.   I was
//          trying to match the docs.  Now I match the CString code
//          - Joe also caught me truncating strings for GetBuffer() calls
//          when the supplied length was less than the current length.
//
//    2000-MAY-25 - Better support for STLPORT's Standard library distribution
//          - Got rid of the NSP macro - it interfered with Koenig lookup
//          - Thanks to Joe Woodbury for catching a TrimLeft() bug that
//          I introduced in January.  Empty strings were not getting
//          trimmed
//
//    2000-APR-17 - Thanks to Joe Vitaterna for pointing out that ReverseFind
//          is supposed to be a const function.
//
//    2000-MAR-07 - Thanks to Ullrich Poll�hne for catching a range bug in one
//          of the overloads of assign.
//
//    2000-FEB-01 - You can now use CStdString on the Mac with CodeWarrior!
//          Thanks to Todd Heckel for helping out with this.
//
//    2000-JAN-23 - Thanks to Jim Cline for pointing out how I could make the
//          Trim() function more efficient.
//          - Thanks to Jeff Kohn for prompting me to find and fix a typo
//          in one of the addition operators that takes _bstr_t.
//          - Got rid of the .CPP file -  you only need StdString.h now!
//
//    1999-DEC-22 - Thanks to Greg Pickles for helping me identify a problem
//          with my implementation of CStdString::FormatV in which
//          resulting string might not be properly NULL terminated.
//
//    1999-DEC-06 - Chris Conti pointed yet another basic_string<> assignment
//          bug that MS has not fixed.  CStdString did nothing to fix
//          it either but it does now!  The bug was: create a string
//          longer than 31 characters, get a pointer to it (via c_str())
//          and then assign that pointer to the original string object.
//          The resulting string would be empty.  Not with CStdString!
//
//    1999-OCT-06 - BufferSet was erasing the string even when it was merely
//          supposed to shrink it.  Fixed.  Thanks to Chris Conti.
//          - Some of the Q172398 fixes were not checking for assignment-
//          to-self.  Fixed.  Thanks to Baptiste Lepilleur.
//
//    1999-AUG-20 - Improved Load() function to be more efficient by using
//          SizeOfResource().  Thanks to Rich Zuris for this.
//          - Corrected resource ID constructor, again thanks to Rich.
//          - Fixed a bug that occurred with UNICODE characters above
//          the first 255 ANSI ones.  Thanks to Craig Watson.
//          - Added missing overloads of TrimLeft() and TrimRight().
//          Thanks to Karim Ratib for pointing them out
//
//    1999-JUL-21 - Made all calls to GetBuf() with no args check length first.
//
//    1999-JUL-10 - Improved MFC/ATL independence of conversion macros
//          - Added SS_NO_REFCOUNT macro to allow you to disable any
//          reference-counting your basic_string<> impl. may do.
//          - Improved ReleaseBuffer() to be as forgiving as CString.
//          Thanks for Fan Xia for helping me find this and to
//          Matthew Williams for pointing it out directly.
//
//    1999-JUL-06 - Thanks to Nigel Nunn for catching a very sneaky bug in
//          ToLower/ToUpper.  They should call GetBuf() instead of
//          data() in order to ensure the changed string buffer is not
//          reference-counted (in those implementations that refcount).
//
//    1999-JUL-01 - Added a true CString facade.  Now you can use CStdString as
//          a drop-in replacement for CString.  If you find this useful,
//          you can thank Chris Sells for finally convincing me to give
//          in and implement it.
//          - Changed operators << and >> (for MFC CArchive) to serialize
//          EXACTLY as CString's do.  So now you can send a CString out
//          to a CArchive and later read it in as a CStdString.   I have
//          no idea why you would want to do this but you can.
//
//    1999-JUN-21 - Changed the CStdString class into the CStdStr template.
//          - Fixed FormatV() to correctly decrement the loop counter.
//          This was harmless bug but a bug nevertheless.  Thanks to
//          Chris (of Melbsys) for pointing it out
//          - Changed Format() to try a normal stack-based array before
//          using to _alloca().
//          - Updated the text conversion macros to properly use code
//          pages and to fit in better in MFC/ATL builds.  In other
//          words, I copied Microsoft's conversion stuff again.
//          - Added equivalents of CString::GetBuffer, GetBufferSetLength
//          - new sscpy() replacement of CStdString::CopyString()
//          - a Trim() function that combines TrimRight() and TrimLeft().
//
//    1999-MAR-13 - Corrected the "NotSpace" functional object to use _istpace()
//          instead of _isspace()   Thanks to Dave Plummer for this.
//
//    1999-FEB-26 - Removed errant line (left over from testing) that #defined
//          _MFC_VER.  Thanks to John C Sipos for noticing this.
//
//    1999-FEB-03 - Fixed a bug in a rarely-used overload of operator+() that
//          caused infinite recursion and stack overflow
//          - Added member functions to simplify the process of
//          persisting CStdStrings to/from DCOM IStream interfaces
//          - Added functional objects (e.g. StdStringLessNoCase) that
//          allow CStdStrings to be used as keys STL map objects with
//          case-insensitive comparison
//          - Added array indexing operators (i.e. operator[]).  I
//          originally assumed that these were unnecessary and would be
//          inherited from basic_string.  However, without them, Visual
//          C++ complains about ambiguous overloads when you try to use
//          them.  Thanks to Julian Selman to pointing this out.
//
//    1998-FEB-?? - Added overloads of assign() function to completely account
//          for Q172398 bug.  Thanks to "Pete the Plumber" for this
//
//    1998-FEB-?? - Initial submission

// MACRO: SS_UNSIGNED
// ------------------
//      This macro causes the addition of a constructor and assignment operator
//      which take unsigned characters.  CString has such functions and in order
//      to provide maximum CString-compatability, this code needs them as well.
//      In practice you will likely never need these functions...

//#define SS_UNSIGNED

#ifdef SS_ALLOW_UNSIGNED_CHARS
  #define SS_UNSIGNED
#endif

// MACRO: SS_SAFE_FORMAT
// ---------------------
//      This macro provides limited compatability with a questionable CString
//      "feature".  You can define it in order to avoid a common problem that
//      people encounter when switching from CString to CStdString.
//
//      To illustrate the problem -- With CString, you can do this:
//
//          CString sName("Joe");
//          CString sTmp;
//          sTmp.Format("My name is %s", sName);                    // WORKS!
//
//      However if you were to try this with CStdString, your program would
//      crash.
//
//          CStdString sName("Joe");
//          CStdString sTmp;
//          sTmp.Format("My name is %s", sName);                    // CRASHES!
//
//      You must explicitly call c_str() or cast the object to the proper type
//
//          sTmp.Format("My name is %s", sName.c_str());            // WORKS!
//          sTmp.Format("My name is %s", static_cast<PCSTR>(sName));// WORKS!
//          sTmp.Format("My name is %s", (PCSTR)sName);        // WORKS!
//
//      This is because it is illegal to pass anything but a POD type as a
//      variadic argument to a variadic function (i.e. as one of the "..."
//      arguments).  The type const char* is a POD type.  The type CStdString
//      is not.  Of course, neither is the type CString, but CString lets you do
//      it anyway due to the way they laid out the class in binary.  I have no
//      control over this in CStdString since I derive from whatever
//      implementation of basic_string is available.
//
//      However if you have legacy code (which does this) that you want to take
//      out of the MFC world and you don't want to rewrite all your calls to
//      Format(), then you can define this flag and it will no longer crash.
//
//      Note however that this ONLY works for Format(), not sprintf, fprintf,
//      etc.  If you pass a CStdString object to one of those functions, your
//      program will crash.  Not much I can do to get around this, short of
//      writing substitutes for those functions as well.

#define SS_SAFE_FORMAT  // use new template style Format() function


// MACRO: SS_NO_IMPLICIT_CAST
// --------------------------
//      Some people don't like the implicit cast to const char* (or rather to
//      const CT*) that CStdString (and MFC's CString) provide.  That was the
//      whole reason I created this class in the first place, but hey, whatever
//      bakes your cake.  Just #define this macro to get rid of the the implicit
//      cast.

//#define SS_NO_IMPLICIT_CAST // gets rid of operator const CT*()


// MACRO: SS_NO_REFCOUNT
// ---------------------
//    turns off reference counting at the assignment level.  Only needed
//    for the version of basic_string<> that comes with Visual C++ versions
//    6.0 or earlier, and only then in some heavily multithreaded scenarios.
//    Uncomment it if you feel you need it.

//#define SS_NO_REFCOUNT

// MACRO: SS_WIN32
// ---------------
//      When this flag is set, we are building code for the Win32 platform and
//      may use Win32 specific functions (such as LoadString).  This gives us
//      a couple of nice extras for the code.
//
//      Obviously, Microsoft's is not the only compiler available for Win32 out
//      there.  So I can't just check to see if _MSC_VER is defined to detect
//      if I'm building on Win32.  So for now, if you use MS Visual C++ or
//      Borland's compiler, I turn this on.  Otherwise you may turn it on
//      yourself, if you prefer

#if defined(_MSC_VER) || defined(__BORLANDC__) || defined(_WIN32)
 #define SS_WIN32
#endif

// MACRO: SS_ANSI

//      When this macro is defined, the code attempts only to use ANSI/ISO
//      standard library functions to do it's work.  It will NOT attempt to use
//      any Win32 of Visual C++ specific functions -- even if they are
//      available.  You may define this flag yourself to prevent any Win32
//      of VC++ specific functions from being called.

// If we're not on Win32, we MUST use an ANSI build

#ifndef SS_WIN32

// MACRO: SS_ALLOCA
// ----------------
//      Some implementations of the Standard C Library have a non-standard
//      function known as alloca().  This functions allows one to allocate a
//      variable amount of memory on the stack.  It is needed to implement
//      the ASCII/MBCS conversion macros.
//
//      I wanted to find some way to determine automatically if alloca() is
//    available on this platform via compiler flags but that is asking for
//    trouble.  The crude test presented here will likely need fixing on
//    other platforms.  Therefore I'll leave it up to you to fiddle with
//    this test to determine if it exists.  Just make sure SS_ALLOCA is or
//    is not defined as appropriate and you control this feature.

#if defined(_MSC_VER) && !defined(SS_ANSI)
  #define SS_ALLOCA
#endif


// MACRO: SS_MBCS
// --------------
//    Setting this macro means you are using MBCS characters.  In MSVC builds,
//    this macro gets set automatically by detection of the preprocessor flag
//    _MBCS.  For other platforms you may set it manually if you wish.  The
//    only effect it currently has is to cause the allocation of more space
//    for wchar_t --> char conversions.
//    Note that MBCS does not mean UNICODE.
//
//  #define SS_MBCS
//

#ifdef _MBCS
  #define SS_MBCS
#endif


// MACRO SS_NO_LOCALE
// ------------------
// If your implementation of the Standard C++ Library lacks the <locale> header,
// you can #define this macro to make your code build properly.  Note that this
// is some of my newest code and frankly I'm not very sure of it, though it does
// pass my unit tests.

// #define SS_NO_LOCALE


// Compiler Error regarding _UNICODE and UNICODE
// -----------------------------------------------
// Microsoft header files are screwy.  Sometimes they depend on a preprocessor
// flag named "_UNICODE".  Other times they check "UNICODE" (note the lack of
// leading underscore in the second version".  In several places, they silently
// "synchronize" these two flags this by defining one of the other was defined.
// In older version of this header, I used to try to do the same thing.
//
// However experience has taught me that this is a bad idea.  You get weird
// compiler errors that seem to indicate things like LPWSTR and LPTSTR not being
// equivalent in UNICODE builds, stuff like that (when they MUST be in a proper
// UNICODE  build).  You end up scratching your head and saying, "But that HAS
// to compile!".
//
// So what should you do if you get this error?
//
// Make sure that both macros (_UNICODE and UNICODE) are defined before this
// file is included.  You can do that by either
//
//    a) defining both yourself before any files get included
//    b) including the proper MS headers in the proper order
//    c) including this file before any other file, uncommenting
//       the #defines below, and commenting out the #errors
//
//  Personally I recommend solution a) but it's your call.

// SS_USE_FACET macro and why we need it:
//
// Since I'm a good little Standard C++ programmer, I use locales.  Thus, I
// need to make use of the use_facet<> template function here.   Unfortunately,
// this need is complicated by the fact the MS' implementation of the Standard
// C++ Library has a non-standard version of use_facet that takes more
// arguments than the standard dictates.  Since I'm trying to write CStdString
// to work with any version of the Standard library, this presents a problem.
//
// The upshot of this is that I can't do 'use_facet' directly.  The MS' docs
// tell me that I have to use a macro, _USE() instead.  Since _USE obviously
// won't be available in other implementations, this means that I have to write
// my OWN macro -- SS_USE_FACET -- that evaluates either to _USE or to the
// standard, use_facet.
//
// If you are having trouble with the SS_USE_FACET macro, in your implementation
// of the Standard C++ Library, you can define your own version of SS_USE_FACET.

// INLINE FUNCTIONS ON WHICH CSTDSTRING RELIES
//
// Usually for generic text mapping, we rely on preprocessor macro definitions
// to map to string functions.  However the CStdStr<> template cannot use
// macro-based generic text mappings because its character types do not get
// resolved until template processing which comes AFTER macro processing.  In
// other words, the preprocessor macro UNICODE is of little help to us in the
// CStdStr template
//
// Therefore, to keep the CStdStr declaration simple, we have these inline
// functions.  The template calls them often.  Since they are inline (and NOT
// exported when this is built as a DLL), they will probably be resolved away
// to nothing.
//
// Without these functions, the CStdStr<> template would probably have to broken
// out into two, almost identical classes.  Either that or it would be a huge,
// convoluted mess, with tons of "if" statements all over the place checking the
// size of template parameter CT.

//    inline int sscpy(PWSTR pDst, PCWSTR pSrc, int nMax=-1);
//    inline int sscpy(PWSTR pDst, PCSTR pSrc, int nMax=-1);
//
// DESCRIPTION:
//    This function is very much (but not exactly) like strcpy.  These
//    overloads simplify copying one C-style string into another by allowing
//    the caller to specify two different types of strings if necessary.
//
//    The strings must NOT overlap
//
//    "Character" is expressed in terms of the destination string, not
//    the source.  If no 'nMax' argument is supplied, then the number of
//    characters copied will be sslen(pSrc).  A NULL terminator will
//    also be added so pDst must actually be big enough to hold nMax+1
//    characters.  The return value is the number of characters copied,
//    not including the NULL terminator.
//
// PARAMETERS:
//    pSrc - the string to be copied FROM.  May be a char based string, an
//         MBCS string (in Win32 builds) or a wide string (wchar_t).
//    pSrc - the string to be copied TO.  Also may be either MBCS or wide
//    nMax - the maximum number of characters to be copied into szDest.  Note
//         that this is expressed in whatever a "character" means to pDst.
//         If pDst is a wchar_t type string than this will be the maximum
//         number of wchar_ts that my be copied.  The pDst string must be
//         large enough to hold least nMaxChars+1 characters.
//         If the caller supplies no argument for nMax this is a signal to
//         the routine to copy all the characters in pSrc, regardless of
//         how long it is.
//
// RETURN VALUE: none

  // FUNCTION:  CStdStr::Format
  //    void _cdecl Formst(CStdStringA& PCSTR szFormat, ...)
  //    void _cdecl Format(PCSTR szFormat);
  //
  // DESCRIPTION:
  //    This function does sprintf/wsprintf style formatting on CStdStringA
  //    objects.  It looks a lot like MFC's CString::Format.  Some people
  //    might even call this identical.  Fortunately, these people are now
  //    dead... heh heh.
  //
  // PARAMETERS:
  //    nId - ID of string resource holding the format string
  //    szFormat - a PCSTR holding the format specifiers
  //    argList - a va_list holding the arguments for the format specifiers.
  //
  // RETURN VALUE:  None.
  // -------------------------------------------------------------------------
  // formatting (using wsprintf style formatting)

    // If they want a Format() function that safely handles string objects
    // without casting

#ifdef SS_SAFE_FORMAT

    // Question:  Joe, you wacky coder you, why do you have so many overloads
    //      of the Format() function
    // Answer:  One reason only - CString compatability.  In short, by making
    //      the Format() function a template this way, I can do strong typing
    //      and allow people to pass CStdString arguments as fillers for
    //      "%s" format specifiers without crashing their program!  The downside
    //      is that I need to overload on the number of arguments.   If you are
    //      passing more arguments than I have listed below in any of my
    //      overloads, just add another one.
    //
    //      Yes, yes, this is really ugly.  In essence what I am doing here is
    //      protecting people from a bad (and incorrect) programming practice
    //      that they should not be doing anyway.  I am protecting them from
    //      themselves.  Why am I doing this?  Well, if you had any idea the
    //      number of times I've been emailed by people about this
    //      "incompatability" in my code, you wouldn't ask.

  // DESCRIPTION:
  //    This function formats the string with sprintf style format-specs.
  //    It makes a general guess at required buffer size and then tries
  //    successively larger buffers until it finds one big enough or a
  //    threshold (MAX_FMT_TRIES) is exceeded.
  //
  // PARAMETERS:
  //    szFormat - a PCSTR holding the format of the output
  //    argList - a Microsoft specific va_list for variable argument lists
  //
  // RETURN VALUE:
  // -------------------------------------------------------------------------

// MSVC USERS: HOW TO EXPORT CSTDSTRING FROM A DLL
//
// If you are using MS Visual C++ and you want to export CStdStringA and
// CStdStringW from a DLL, then all you need to
//
//    1.  make sure that all components link to the same DLL version
//      of the CRT (not the static one).
//    2.  Uncomment the 3 lines of code below
//    3.  #define 2 macros per the instructions in MS KnowledgeBase
//      article Q168958.  The macros are:
//
//    MACRO    DEFINTION WHEN EXPORTING    DEFINITION WHEN IMPORTING
//    -----    ------------------------    -------------------------
//    SSDLLEXP  (nothing, just #define it)    extern
//    SSDLLSPEC  __declspec(dllexport)      __declspec(dllimport)
//
//    Note that these macros must be available to ALL clients who want to
//    link to the DLL and use the class.  If they
//
// A word of advice: Don't bother.
//
// Really, it is not necessary to export CStdString functions from a DLL.  I
// never do.  In my projects, I do generally link to the DLL version of the
// Standard C++ Library, but I do NOT attempt to export CStdString functions.
// I simply include the header where it is needed and allow for the code
// redundancy.
//
// That redundancy is a lot less than you think.  This class does most of its
// work via the Standard C++ Library, particularly the base_class basic_string<>
// member functions.  Most of the functions here are small enough to be inlined
// anyway.  Besides, you'll find that in actual practice you use less than 1/2
// of the code here, even in big projects and different modules will use as
// little as 10% of it.  That means a lot less functions actually get linked
// your binaries.  If you export this code from a DLL, it ALL gets linked in.
//
// I've compared the size of the binaries from exporting vs NOT exporting.  Take
// my word for it -- exporting this code is not worth the hassle.

  //   dwError - a DWORD value representing the error code to be translated
  //   dwLangId - the language id to use.  defaults to english.
  //
  // RETURN VALUE:
  //   a CStdStringA equivalent of the error code.  Currently, this function
  //   only returns either English of the system default language strings.
