I use GetContextMenuManager()->ShowPopupMenu and I need one item to be
disabled in some cases.
Following code does not work for me:
CMFCPopupMenu* pMenuActive = CMFCPopupMenu::GetActiveMenu();
CMFCToolBarMenuButton* pMenuButton = pMenuActive->GetMenuItem(0);
pMenuButton->EnableWindow(FALSE);
Attempt to use EnableMenuItem also did not help.

Could you please advise how to display CMFCPopupMenu with an item disabled
conditionally?

Thanks,
-Boris

Have you trid ON_UPDATE_COMMAND_UI

In your window's message map:
ON_UPDATE_COMMAND_UI(ID_OF_MENUITEM,OnUpdateMenuItem)


void CMyWndClass::OnUpdateMenuItem(CCmdUI *pCmdUI)
{
pCmdUI->Enable(BasedOnYourCondition);
}

AliR.

It sounds like you are using a menu that is mapped to command handlers.
The handler takes precedence so use a ON_UPDATE_COMMAND_UI(...) to
disable the item.

Best, Dan.
