//  MODULE:   ctxmenu.cpp
//
//  PURPOSE:   Implements the IContextMenu member functions necessary to support
//             the context menu portioins of this shell extension.  Context menu
//             shell extensions are called when the user right clicks on a file
//             (of the type registered for the shell extension--see SHELLEXT.REG
//             for details on the registry entries.  In this sample, the relevant
//             files are of type .W3D) in the Explorer, or selects the File menu 
//             item.

//  FUNCTION: CShellExt::QueryContextMenu(HMENU, UINT, UINT, UINT, UINT)
//
//  PURPOSE: Called by the shell just before the context menu is displayed.
//           This is where you add your specific menu items.
//
//  PARAMETERS:
//    hMenu      - Handle to the context menu
//    indexMenu  - Index of where to begin inserting menu items
//    idCmdFirst - Lowest value for new menu ID's
//    idCmtLast  - Highest value for new menu ID's
//    uFlags     - Specifies the context of the menu event
//
//  RETURN VALUE:
//
//
//  COMMENTS:
