// Note!
//
//  If this DLL is dynamically linked against the MFC
//  DLLs, any functions exported from this DLL which
//  call into MFC must have the AFX_MANAGE_STATE macro
//  added at the very beginning of the function.
//
//  For example:
//
//  extern "C" BOOL PASCAL EXPORT ExportedFunction()
//  {
//   AFX_MANAGE_STATE(AfxGetStaticModuleState());
//   // normal function body here
//  }
//
//  It is very important that this macro appear in each
//  function, prior to any calls into MFC.  This means that
//  it must appear as the first statement within the
//  function, even before any object variable declarations
//  as their constructors may generate calls into the MFC
//  DLL.
//
//  Please see MFC Technical Notes 33 and 58 for additional
//  details.
