  TCHAR is a macro. It contains either a short * or a char *, depending on if Unicode is defined. I believe that std::string also maps to Unicode or ANSI, so this should always work

  TCHAR buffer[MAX_PATH+1];

  DWORD iNombreChars = sizeof(buffer);

  iNombreChars = GetCurrentDirectory(iNombreChars, buffer);

  string strPath(buffer);

  You may need

  string strPath(&buffer[0]);

  but I don't think so.

This works: TCHAR buffer[MAX_PATH+1]; DWORD iNombreChars = GetCurrentDirectory(MAX_PATH, buffer); string strPath; strPath.assign(&buffer[0], &buffer[iNombreChars]); FWIW, this works because a pointer is an acceptable random access iterator.

  Or simply like this:

  std::string str(MAX_PATH+1, 0);
  GetCurrentDirectory(MAX_PATH, &str[0]);

  thanks for helping
  
  tho im getting this error after doing your steps :
  
  Error 1 error C2664: 'std::basic_string<_Elem,_Traits,_Ax>::basic_string(std::basic_string<_Elem,_Traits,_Ax>::_Has_debug_it)' : cannot convert parameter 1 from 'TCHAR *__w64 ' to 'std::basic_string<_Elem,_Traits,_Ax>::_Has_debug_it' c:\projets\banquet\banquet\banquesecuretrav.cpp 110
  
  TCHAR buffer[MAX_PATH+1];
  DWORD iNombreChars = sizeof(buffer);
  
  iNombreChars = GetCurrentDirectory(iNombreChars, buffer);
  
  string strPath(&buffer[0]); //Also tried without & and [0]

  As far as I understand it, std::string is always basic_string<char> and std::wstring is basic_string<wchar_t>. This means that you need to use std::string if TCHAR is a char (ANSI build) and std::wstring if TCHAR is a short (Unicode build).

  There is a constructor for basic_string that takes a pointer to the buffer to copy (and an allocator) - Either of the string constructors should work if the type of string matches the current build setting - if ANSI then strPath should be std::string, if Unicode then strPath should be std::wstring.

  Best regards,

  The usage of sizeof here is wrong. GetCurrentDirectory wants the sizeof chars that are allowed, not the buffers size.

  DWORD iNombreChars = sizeof(buffer)/sizeof(TCHAR);

  Would be correct.
