In CEditView, if  I select some text and cut it, my Undo menu gets disabled. Also my toolbar button to handle Undo command gets greyed. I want to control the enable/disable of these by myself. How can I do it?

first you need to set

m_bAutoMenuEnable  = FALSE;

it is member of CFrameWnd, so if you are using standard SDI/MDI app you can do it in CMainFrame constractor

Downside here is that now you need to overwrite UPDATE_COMMAND_UI handler for EVERY menu item you want to enable/disable based on certain conditions.

something like this:

void CMainFrame::OnUpdateFileLogon(CCmdUI* pCmdUI)
{
     if (SecurityDLL_IsUserLoggedOn())
          pCmdUI->Enable(FALSE);
}
otherwise they will always be enabled.

Hope it helps

hi mblat,
I set m_bAutoMenuEnable  = FALSE; in constructor of my CMainFrame. It still disables the menu and toolbar button on using Cut. It's ok for  me if they never get disabled. Comment with m_bAutoMenuEnable in AFXWIN.H says:

BOOL m_bAutoMenuEnable;
          // TRUE => menu items without handlers will be disabled

I think this is for automatic enabling/disabling of menu items with/without handlers. What I need is the  menu item never gets automatically disabled.

// TRUE => menu items without handlers will be disabled

so, did you define handler?  try to define it and then try to define UPDATE_COMMAND_UI handler.
