Hi!

In order to implement multiple languages in my application,
I'm using stringtable resources like this:

**********

STRINGTABLE LANGUAGE LANG_GERMAN, SUBLANG_NEUTRAL
BEGIN

  START_EDITOR       "&Editor";
  START_VERWERFEN    "&Verwerfen";

END

STRINGTABLE LANGUAGE LANG_ENGLISH, SUBLANG_NEUTRAL
BEGIN

  START_EDITOR       "&Editor";
  START_VERWERFEN    "&Discard";

END

**********

I've found a piece of code on MSDN which works:

**********

wchar_t* GetWideStringFromStringTable(UINT uStringID, int iLanguage)
{
   wchar_t   *pwchMem, *pwchCur;
   UINT      idRsrcBlk = (uStringID >> 4) + 1;
   int       strIndex  = uStringID % 16;
   HINSTANCE hModule = NULL;
   HRSRC     hResource = NULL;

   hResource = FindResourceEx(HInstance,
                              RT_STRING,
                              MAKEINTRESOURCE(idRsrcBlk),
                              MAKELANGID(iLanguage, SUBLANG_NEUTRAL));

   if (hResource != NULL)
   {
      pwchMem = (wchar_t*) LoadResource(hModule, hResource);

      if (pwchMem != NULL)
      {
         pwchCur = pwchMem;

         for (int i = 0; i < 16; i++)
         {
            if (*pwchCur)
            {
               int cchString = *pwchCur;  // String size in characters.
               pwchCur++;

               if (i == strIndex)
               {
                  // The string has been found in the string table.

                  wchar_t *pwchTemp = new wchar_t[cchString];
                  wcsncpy(pwchTemp, pwchCur, cchString);
                  pwchTemp[cchString] = '\0';

                  return pwchTemp;
               }

               pwchCur += cchString;
            }
            else
               pwchCur++;
         }
      }
   }

   return NULL;
}

**********

The problem: When I switch languages during the run of my
application, I sometimes get the error "illegal pointer operation"
or the application throws an "EExternalException".

Could anybody please tell me why?

Additional question: In the code above I replaced "wchar_t"
with "char" and "wcsncpy" with "strncpy", but then the code
won't work any more. Why?

Thanx alot
