The code between /* ### */ is - of course - not in the original ...
8-|

const CString& CString::operator=(LPCTSTR lpsz)
{
/* ### */
if (lpsz != NULL && HIWORD(lpsz) == NULL)
{
UINT nID = LOWORD((DWORD)lpsz);
if (!LoadString(nID))
TRACE1("Warning: implicit LoadString(%u) failed\n", nID);
return *this;
}
/* ### */

ASSERT(lpsz == NULL || AfxIsValidString(lpsz));
AssignCopy(SafeStrlen(lpsz), lpsz);
return *this;
}

thanks microsoft!

Passing a resource ID is supported in the CString ctor, but apparently not
in the operator =. How were you planning to use this capability? Like
this?

  CString str;
  str = MAKEINTRESOURCE(IDC_MY_STRING);

This is highly unusual. This code is more readable and supported in the
standard CString:

  CString str;
  str = CString(MAKEINTRESOURCE(IDC_MY_STRING));
