    Since it's SDI, the preferred way of doing this is with the ON_COMMAND and ON_UPDATE_COMMAND_UI macros.

    Look in the MESSAGE_MAP of your view. You should see some common handlers already:

    Code:
    BEGIN_MESSAGE_MAP(CMyView, CScrollView)
      //...
      ON_COMMAND(ID_EDIT_COPY, OnEditCopy)
      ON_UPDATE_COMMAND_UI(ID_EDIT_COPY, OnUpdateEditCopy)
    END_MESSAGE_MAP()
    See:

    And if you are not using MFC, take a look at WM_INITPOPUPMENU to get the menu just before it is shown, then use EnableMenuItem() to Enable or Disable it.
