In my Studio 2008 (VC++ 2008), I set the menu item's property to Grayed=True, Enabled=FALSE.

Doesn't do a thing either.

I'm moving ON_UPDATE_COMMAND_UI() into the //AFX_MSG_MAP section BEGIN_MESSAGE_MAP...

(PrevProgramView.cpp)
BEGIN_MESSAGE_MAP(CPrevProgramView, CView)
//{{AFX_MSG_MAP(CPrevProgramView)
     ON_COMMAND(ID_FILE_ADJUST, OnFileAdjustTimes)
     ON_UPDATE_COMMAND_UI(ID_FILE_ADJUST, OnUpdateFileAdjustTimes)
//}}AFX_MSG_MAP
END_MESSAGE_MAP()


then the function
void CPrevProgramView::OnUpdateFileAdjustTimes(CCmdUI *pCmdUI)
{
     if (m_existingFile)
          pCmdUI->Enable(TRUE);
     else
          pCmdUI->Enable(FALSE);
}

and my resource property for ID_FILE_ADJUST is set to: Enabled=False, Greyed=True

BEGIN_MESSAGE_MAP(CMyDlg, CDialog)
	//{{AFX_MSG_MAP(CMyDlg)
	ON_COMMAND(ID_UTILITIES_CONVERT, OnUtilitiesConvert)
	ON_UPDATE_COMMAND_UI(ID_UTILITIES_CONVERT, &CMyDlg::OnUpdateUtilitiesConvert)
	//}}AFX_MSG_MAP
END_MESSAGE_MAP()

and the new function (that IS called) is 
void CMyDlg::OnUpdateUtilitiesConvert(CCmdUI *pCmdUI)
{
	CFileStatus	cfStat;
	CString		sProcName;
	BOOL		bExists = FALSE;

	sProcName.LoadStringA(IDS_COORD_CONV);

	// Get the status of this file - exists or not
	bExists = CFile::GetStatus(sProcName, cfStat);
	pCmdUI->Enable( bExists );
}
with my resource ID_UTILITIES_CONVERT set to Enabled=False, Greyed=True.

Is there a difference in how menu items are handle in Doc/View applications Vs. a Dialog-based app?
