Hallo Phil,

 PC> How do I create a MS_CONDITIONALCASCADE menuitem?

 PC> Can I add MS_CONDITIONALCASCADE to the .rc file, or do I have to call
 PC> some API?

you have to use API calls. Try this:

VOID
setCascadeDefault( HWND hwndMenu, USHORT usSubmenu, USHORT usDefault )
//-------------------------------------------------------------------------
// This function sets the default menuitem for the specified cascade menu.
//
// Input:  hwndMenu - specifies the menu window handle.
//         usSubmenu - specifies the id of the cascade menu.
//         usDefault - specifies the id of the default menuitem.
//-------------------------------------------------------------------------
{
   MENUITEM miItem;
   ULONG    ulStyle;

   WinSendMsg(chwndMenu, MM_QUERYITEM,
              MPFROM2SHORT(usSubmenu,TRUE), MPFROMP(&miItem) );
   ulStyle = WinQueryWindowULong(miItem.hwndSubMenu,QWL_STYLE);
   ulStyle |= MS_CONDITIONALCASCADE;
   WinSetWindowULong(miItem.hwndSubMenu,QWL_STYLE,ulStyle);
   WinSendMsg( miItem.hwndSubMenu, MM_SETDEFAULTITEMID,
               MPFROM2SHORT(usDefault,FALSE), 0L );
   WinSendMsg( miItem.hwndSubMenu, MM_SETITEMATTR,
               MPFROM2SHORT(usDefault,TRUE),
               MPFROM2SHORT(MIA_CHECKED,(TRUE?MIA_CHECKED:0)) );
}

ciao
  Richard
