// 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 .GAK) in the Explorer, or selects the File menu
// item.
//
#include "priv.h"
#include "shellext.h"
//
// 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:
