What is "afxContextIsDLL" ? I got this error!

MFC >> What is "afxContextIsDLL" ? I got this error!

hi,all
I have a exe, unicode version and non MFC, it will load a dll(Unicode version) when it starts up. When I exit the program, I got a access violation error.
The exe app is like :
BOOL CMyApp::InitInstance()
{
AfxEnableControlContainer();
#ifdef _AFXDLL
Enable3dControls();
#else
Enable3dControlsStatic()
#endif
...............
..... Load my dll and run it, the main interface is in this dll
..... Free the dll
return FALSE;
}

And then I get the error at here:
int CWinApp::ExitInstance()
{
if (m_pCmdInfo == NULL ||m_pCmdInfo->m_nShellCommand != CCommandLineInfo::AppUnregister)
{
if (!afxContextIsDLL)//Error occurs here, in watch win, it shows this symbol is not found.
SaveStdProfileSettings();
}

// Cleanup DAO if necessary
if (m_lpfnDaoTerm != NULL)
{
// If a DLL, YOU must call AfxDaoTerm prior to ExitInstance
ASSERT(!afxContextIsDLL);
(*m_lpfnDaoTerm)();
}

return m_msgCur.wParam; // returns the value from PostQuitMessage
}

So what is afxContextIsDLL?
Thanks
