// Object identifiers in the explorer's name space (ItemID and IDList)
//
// All the items that the user can browse with the explorer (such as files,
// directories, servers, work-groups, etc.) has an identifier which is unique
// among items within the parent folder. Those identifiers are called item
// IDs (SHITEMID). Since all its parent folders have their own item IDs,
// any items can be uniquely identified by a list of item IDs, which is called
// an ID list (ITEMIDLIST).
//
// ID lists are almost always allocated by the task allocator (see some
// description below as well as OLE 2.0 SDK) and may be passed across
// some of shell interfaces (such as IShellFolder). Each item ID in an ID list
// is only meaningful to its parent folder (which has generated it), and all
// the clients must treat it as an opaque binary data except the first two
// bytes, which indicates the size of the item ID.
//
// When a shell extension -- which implements the IShellFolder interace --
// generates an item ID, it may put any information in it, not only the data
// with that it needs to identifies the item, but also some additional
// information, which would help implementing some other functions efficiently.
// For example, the shell's IShellFolder implementation of file system items
// stores the primary (long) name of a file or a directory as the item
// identifier, but it also stores its alternative (short) name, size and date
// etc.
//
// When an ID list is passed to one of shell APIs (such as SHGetPathFromIDList),
// it is always an absolute path -- relative from the root of the name space,
// which is the desktop folder. When an ID list is passed to one of IShellFolder
// member function, it is always a relative path from the folder (unless it
// is explicitly specified).

// Task allocator API
//
// All the shell extensions MUST use the task allocator (see OLE 2.0
// programming guild for its definition) when they allocate or free
// memory objects (mostly ITEMIDLIST) that are returned across any
// shell interfaces. There are two ways to access the task allocator
// from a shell extension depending on whether or not it is linked with
// OLE32.DLL or not (purely for efficiency).
//
// (1) A shell extension which calls any OLE API (i.e., linked with
// OLE32.DLL) should call OLE's task allocator (by retrieving
// the task allocator by calling CoGetMalloc API).
//
// (2) A shell extension which does not call any OLE API (i.e., not linked
// with OLE32.DLL) should call the shell task allocator API (defined
// below), so that the shell can quickly loads it when OLE32.DLL is not
// loaded by any application at that point.
//
// Notes:
// In next version of Windowso release, SHGetMalloc will be replaced by
// the following macro.
//
// #define SHGetMalloc(ppmem) CoGetMalloc(MEMCTX_TASK, ppmem)

// IContextMenu interface
//
// [OverView]
//
// The shell uses the IContextMenu interface in following three cases.
//
// case-1: The shell is loading context menu extensions.
//
// When the user clicks the right mouse button on an item within the shell's
// name space (i.g., file, directory, server, work-group, etc.), it creates
// the default context menu for its type, then loads context menu extensions
// that are registered for that type (and its base type) so that they can
// add extra menu items. Those context menu extensions are registered at
// HKCR\{ProgID}\shellex\ContextMenuHandlers.
//
// case-2: The shell is retrieving a context menu of sub-folders in extended
// name-space.
//
// When the explorer's name space is extended by name space extensions,
// the shell calls their IShellFolder::GetUIObjectOf to get the IContextMenu
// objects when it creates context menus for folders under those extended
// name spaces.
//
// case-3: The shell is loading non-default drag and drop handler for directories.
//
// When the user performed a non-default drag and drop onto one of file
// system folders (i.e., directories), it loads shell extensions that are
// registered at HKCR\{ProgID}\DragDropHandlers.
//
//
// [Member functions]
//
//
// IContextMenu::QueryContextMenu
//
// This member function may insert one or more menuitems to the specified
// menu (hmenu) at the specified location (indexMenu which is never be -1).
// The IDs of those menuitem must be in the specified range (idCmdFirst and
// idCmdLast). It returns the maximum menuitem ID offset (ushort) in the
// 'code' field (low word) of the scode.
//
// The uFlags specify the context. It may have one or more of following
// flags.
//
// CMF_DEFAULTONLY: This flag is passed if the user is invoking the default
// action (typically by double-clicking, case 1 and 2 only). Context menu
// extensions (case 1) should not add any menu items, and returns NOERROR.
//
// CMF_VERBSONLY: The explorer passes this flag if it is constructing
// a context menu for a short-cut object (case 1 and case 2 only). If this
// flag is passed, it should not add any menu-items that is not appropriate
// from a short-cut.
// A good example is the "Delete" menuitem, which confuses the user
// because it is not clear whether it deletes the link source item or the
// link itself.
//
// CMF_EXPLORER: The explorer passes this flag if it has the left-side pane
// (case 1 and 2 only). Context menu extensions should ignore this flag.
//
// High word (16-bit) are reserved for context specific communications
// and the rest of flags (13-bit) are reserved by the system.
//
//
// IContextMenu::InvokeCommand
//
// This member is called when the user has selected one of menuitems that
// are inserted by previous QueryContextMenu member. In this case, the
// LOWORD(lpici->lpVerb) contains the menuitem ID offset (menuitem ID -
// idCmdFirst).
//
// This member function may also be called programmatically. In such a case,
// lpici->lpVerb specifies the canonical name of the command to be invoked,
// which is typically retrieved by GetCommandString member previously.
//
// Parameters in lpci:
// cbSize -- Specifies the size of this structure (sizeof(*lpci))
// hwnd -- Specifies the owner window for any message/dialog box.
// fMask -- Specifies whether or not dwHotkey/hIcon paramter is valid.
// lpVerb -- Specifies the command to be invoked.
// lpParameters -- Parameters (optional)
// lpDirectory -- Working directory (optional)
// nShow -- Specifies the flag to be passed to ShowWindow (SW_*).
// dwHotKey -- Hot key to be assigned to the app after invoked (optional).
// hIcon -- Specifies the icon (optional).
//
//
// IContextMenu::GetCommandString
//
// This member function is called by the explorer either to get the
// canonical (language independent) command name (uFlags == GCS_VERB) or
// the help text ((uFlags & GCS_HELPTEXT) != 0) for the specified command.
// The retrieved canonical string may be passed to its InvokeCommand
// member function to invoke a command programmatically. The explorer
// displays the help texts in its status bar; therefore, the length of
// the help text should be reasonably short (<40 characters).
//
// Parameters:
// idCmd -- Specifies menuitem ID offset (from idCmdFirst)
// uFlags -- Either GCS_VERB or GCS_HELPTEXT
// pwReserved -- Reserved (must pass NULL when calling, must ignore when called)
// pszName -- Specifies the string buffer.
// cchMax -- Specifies the size of the string buffer.

// IExtractIcon interface
//
// This interface is used in two different places in the shell.
//
// Case-1: Icons of sub-folders for the scope-pane of the explorer.
//
// It is used by the explorer to get the "icon location" of
// sub-folders from each shell folders. When the user expands a folder
// in the scope pane of the explorer, the explorer does following:
// (1) binds to the folder (gets IShellFolder),
// (2) enumerates its sub-folders by calling its EnumObjects member,
// (3) calls its GetUIObjectOf member to get IExtractIcon interface
// for each sub-folders.
// In this case, the explorer uses only IExtractIcon::GetIconLocation
// member to get the location of the appropriate icon. An icon location
// always consists of a file name (typically DLL or EXE) and either an icon
// resource or an icon index.
//
//
// Case-2: Extracting an icon image from a file
//
// It is used by the shell when it extracts an icon image
// from a file. When the shell is extracting an icon from a file,
// it does following:
// (1) creates the icon extraction handler object (by getting its CLSID
// under the {ProgID}\shell\ExtractIconHanler key and calling
// CoCreateInstance requesting for IExtractIcon interface).
// (2) Calls IExtractIcon::GetIconLocation.
// (3) Then, calls IExtractIcon::ExtractIcon with the location/index pair.
// (4) If (3) returns NOERROR, it uses the returned icon.
// (5) Otherwise, it recursively calls this logic with new location
// assuming that the location string contains a fully qualified path name.
//
// From extension programmer's point of view, there are only two cases
// where they provide implementations of IExtractIcon:
// Case-1) providing explorer extensions (i.e., IShellFolder).
// Case-2) providing per-instance icons for some types of files.
//
// Because Case-1 is described above, we'll explain only Case-2 here.
//
// When the shell is about display an icon for a file, it does following:
// (1) Finds its ProgID and ClassID.
// (2) If the file has a ClassID, it gets the icon location string from the
// "DefaultIcon" key under it. The string indicates either per-class
// icon (e.g., "FOOBAR.DLL,2") or per-instance icon (e.g., "%1,1").
// (3) If a per-instance icon is specified, the shell creates an icon
// extraction handler object for it, and extracts the icon from it
// (which is described above).
//
// It is important to note that the shell calls IExtractIcon::GetIconLocation
// first, then calls IExtractIcon::Extract. Most application programs
// that support per-instance icons will probably store an icon location
// (DLL/EXE name and index/id) rather than an icon image in each file.
// In those cases, a programmer needs to implement only the GetIconLocation
// member and it Extract member simply returns S_FALSE. They need to
// implement Extract member only if they decided to store the icon images
// within files themselved or some other database (which is very rare).
//
//
//
// [Member functions]
//
//
// IExtractIcon::GetIconLocation
//
// This function returns an icon location.
//
// Parameters:
// uFlags [in] -- Specifies if it is opened or not (GIL_OPENICON or 0)
// szIconFile [out] -- Specifies the string buffer buffer for a location name.
// cchMax [in] -- Specifies the size of szIconFile (almost always MAX_PATH)
// piIndex [out] -- Sepcifies the address of UINT for the index.
// pwFlags [out] -- Returns GIL_* flags
// Returns:
// NOERROR, if it returns a valid location; S_FALSE, if the shell use a
// default icon.
//
// Notes: The location may or may not be a path to a file. The caller can
// not assume anything unless the subsequent Extract member call returns
// S_FALSE.
//
// if the returned location is not a path to a file, GIL_NOTFILENAME should
// be set in the returned flags.
//
// IExtractIcon::Extract
//
// This function extracts an icon image from a specified file.
//
// Parameters:
// pszFile [in] -- Specifies the icon location (typically a path to a file).
// nIconIndex [in] -- Specifies the icon index.
// phiconLarge [out] -- Specifies the HICON variable for large icon.
// phiconSmall [out] -- Specifies the HICON variable for small icon.
// nIconSize [in] -- Specifies the size icon required (size of large icon)
// LOWORD is the requested large icon size
// HIWORD is the requested small icon size
// Returns:
// NOERROR, if it extracted the from the file.
// S_FALSE, if the caller should extract from the file specified in the

// [Member functions]
//
//
// IShellBrowser::GetWindow(phwnd)
//
// Inherited from IOleWindow::GetWindow.
//
//
// IShellBrowser::ContextSensitiveHelp(fEnterMode)
//
// Inherited from IOleWindow::ContextSensitiveHelp.
//
//
// IShellBrowser::InsertMenusSB(hmenuShared, lpMenuWidths)
//
// Similar to the IOleInPlaceFrame::InsertMenus. The explorer will put
// "File" and "Edit" pulldown in the File menu group, "View" and "Tools"
// in the Container menu group and "Help" in the Window menu group. Each
// pulldown menu will have a uniqu ID, FCIDM_MENU_FILE/EDIT/VIEW/TOOLS/HELP.
// The view is allowed to insert menuitems into those sub-menus by those
// IDs must be between FCIDM_SHVIEWFIRST and FCIDM_SHVIEWLAST.
//
//
// IShellBrowser::SetMenuSB(hmenuShared, holemenu, hwndActiveObject)
//
// Similar to the IOleInPlaceFrame::SetMenu. The explorer ignores the
// holemenu parameter (reserved for future enhancement) and performs
// menu-dispatch based on the menuitem IDs (see the description above).
// It is important to note that the explorer will add different
// set of menuitems depending on whether the view has a focus or not.
// Therefore, it is very important to call ISB::OnViewWindowActivate
// whenever the view window (or its children) gets the focus.
//
//
// IShellBrowser::RemoveMenusSB(hmenuShared)
//
// Same as the IOleInPlaceFrame::RemoveMenus.
//
//
// IShellBrowser::SetStatusTextSB(lpszStatusText)
//
// Same as the IOleInPlaceFrame::SetStatusText. It is also possible to
// send messages directly to the status window via SendControlMsg.
//
//
// IShellBrowser::EnableModelessSB(fEnable)
//
// Same as the IOleInPlaceFrame::EnableModeless.
//
//
// IShellBrowser::TranslateAcceleratorSB(lpmsg, wID)
//
// Same as the IOleInPlaceFrame::TranslateAccelerator, but will be
// never called because we don't support EXEs (i.e., the explorer has
// the message loop). This member function is defined here for possible
// future enhancement.
//
//
// IShellBrowser::BrowseObject(pidl, wFlags)
//
// The view calls this member to let shell explorer browse to another
// folder. The pidl and wFlags specifies the folder to be browsed.
//
// Following three flags specifies whether it creates another window or not.
// SBSP_SAMEBROWSER -- Browse to another folder with the same window.
// SBSP_NEWBROWSER -- Creates another window for the specified folder.
// SBSP_DEFBROWSER -- Default behavior (respects the view option).
//
// Following three flags specifies open, explore, or default mode. These .
// are ignored if SBSP_SAMEBROWSER or (SBSP_DEFBROWSER && (single window .
// browser || explorer)). .
// SBSP_OPENMODE -- Use a normal folder window
// SBSP_EXPLOREMODE -- Use an explorer window
// SBSP_DEFMODE -- Use the same as the current window
//
// Following three flags specifies the pidl.
// SBSP_ABSOLUTE -- pidl is an absolute pidl (relative from desktop)
// SBSP_RELATIVE -- pidl is relative from the current folder.
// SBSP_PARENT -- Browse the parent folder (ignores the pidl)
//
//
// IShellBrowser::GetViewStateStream(grfMode, ppstm)
//
// The browser returns an IStream interface as the storage for view
// specific state information.
//
// grfMode -- Specifies the read/write access (STGM_READ/WRITE/READWRITE)
// ppstm -- Specifies the LPSTREAM variable to be filled.
//
//
// IShellBrowser::GetControlWindow(id, phwnd)
//
// The shell view may call this member function to get the window handle
// of Explorer controls (toolbar or status winodw -- FCW_TOOLBAR or
// FCW_STATUS).
//
//
// IShellBrowser::SendControlMsg(id, uMsg, wParam, lParam, pret)
//
// The shell view calls this member function to send control messages to
// one of Explorer controls (toolbar or status window -- FCW_TOOLBAR or
// FCW_STATUS).
//
//
// IShellBrowser::QueryActiveShellView(IShellView * ppshv)
//
// This member returns currently activated (displayed) shellview object.
// A shellview never need to call this member function.
//
//
// IShellBrowser::OnViewWindowActive(pshv)
//
// The shell view window calls this member function when the view window
// (or one of its children) got the focus. It MUST call this member before
// calling IShellBrowser::InsertMenus, because it will insert different
// set of menu items depending on whether the view has the focus or not.
//
//
// IShellBrowser::SetToolbarItems(lpButtons, nButtons, uFlags)
//
// The view calls this function to add toolbar items to the exporer's
// toolbar. "lpButtons" and "nButtons" specifies the array of toolbar
// items. "uFlags" must be one of FCT_MERGE, FCT_CONFIGABLE, FCT_ADDTOEND.
