Here Enabling and Disabling of manager Menu can be done,
now u have updated the manager menu like this :

SORT
|
MANAGER --- SUBMENU1
--- SUBMENU2

here u will not be able to disable the MANAGER menu as u will not be able to add an Valid event for it. Since u have added the SUNBMENU's now , u can again create the ONUPDATE event for them, then try to put the same logic into them and disable both of the sub menus. Here in the MANAGER menu when u click on it no event will be generated. MANAGER menu will be now same as SORT menu where valid event handler's cant be added. hope this helps u .

Yes, that is correct. But I can disable Sort. The code for that is given below.

C++ Syntax (Toggle Plain Text) 
  1. void CDept::DisableSort(void)
  2. {
  3. 	CWnd* pParent = GetParent(); // This is a point to the window
  4. 	 // This is a pointer to the menu on that window
  5.         CMenu* pMenu = pParent->GetMenu();        
  6.  
  7.         if (m_pSet->GetRecordCount()==0) {
  8. 		MessageBox("Error", MB_ICONSTOP);
  9.                 // This disables the menu item in the 6th position which  
  10.                     is  Sort
  11. 		pMenu->EnableMenuItem(5 , MF_BYPOSITION | MF_GRAYED );		
  12. 	}
  13. 	m_pSet->MoveFirst();
  14. 	pParent->DrawMenuBar(); // To redraw the menu
  15. 	OnSortEmployee(); // To reset the sort back to the “default condition”
  16. }

But the question is how am i suppose to gray out or disable the menu item in the sort. Check out the code bellow
C++ Syntax (Toggle Plain Text) 
  1. //(5) is the position of the sort, (MF_BYPOSITION ) is saying that it can be done by position of the Sort which is 5, (MF_GRAYED) means it grays out the SORT. 
  2.  
  3. pMenu->EnableMenuItem(5 , MF_BYPOSITION | MF_GRAYED );

Now the problem is I can not do the same thing for the sub menu of Sort. But I don't know the position for that. If there is another piece of code to get the job done, then I have no idea about it. This is where I am stuck.
