        Hi back...

        I've just figured it out myself, so I'll be happy to pass on that
knowledge (it now seems obvious).  First, the concepts.  One thing that
differentiates dialogs from frames (regular windows), is that they repaint
themselves.  When you load up a dialog (WinLoadDlg), the dialog paints
itself automatically.  But when you add something to the dialog, like, oh,
lets say a menu, you need to tell the dialog that something has changed, and
that it needs to repaint itself.  So the answer to the question is to send
the WM_UPDATEFRAME message.  In my program, I've decided to add the menu when
the dialog is initialized.  So here's my code:

        MRESULT EXPENTRY MyDialogFunction(HWND hdlg, ULONG msg, MPARAM ...){
        HWND hmenu;

        switch(msg){
        case WM_INITDLG:
                hmenu=WinLoadMenu(hdlg, 0, IDD_MENU);
                WinSendMsg(hdlg, WM_UPDATEFRAME, 0, 0);
                ...


        It almost seems simple now that I know the answer.  Here's some
additional info that might be useful.  If you want to know the state of a
menu item, use:

        WinSendMsg(hmenu,                      //menu handle
                   MM_QUERYITEMATTR,           //message
                   MPFROM2SHORT(ID_MENUITEM,   //which menuitem to check on
                                TRUE),         //search submenus for menuitem
                                                 or just the base menu
                   MPFROM2SHORT(attribute,     //report on which attribute
                                0));           //unused

        For example, if you wanted to check on MIA_DISABLED, this function
would return TRUE if the menuitem was disabled, and false if the menuitem
was ?functional? (not sure of the correct term).

        And if you want to set an attribute, use:

        WinSendMsg(hmenu,
                   MM_SETITEMATTR,
                   MPFROM2SHORT(ID_MENUITEM,
                                TRUE),
                   MPFROM2SHORT(attribute,     //which attribute to change
                                set));         //change attribute to what

        For example, if you wanted to clear MIA_DISABLE, you would use:

WinSendMsg(hmenu, MM_SETITEMATTR, MPFROM2SHORT(ID_MENUITEM, TRUE),
        MPFROM2SHORT(MIA_DISABLED, 0);

And if you wanted to check it, then you would replace 0 with MIA_DISABLED.

        Related functions also allow you to insert, remove, and delete
menuitems.  But I don't need that functionality, so I haven't gone over it
yet.
