//
// Interface: IShellLinkTracker
//
//  The IShellLinkTracker interface is used to access the ShellLink's
// CTracker object.  For example, Monikers call this interface to set
// the creation flags in the CTracker.
//
//
// [Member functions]
//
//    Initialize
//          This function is called to set the Creation Flags on
//          a ShellLinkTracker object
//
//          Parameters: [DWORD] dwCreationFlags
//
//    GetTrackFlags
//          This function is used to get the creation flags (known externally
//          as "track flags").
//  
//          Parameters: [DWORD *] pdwTrackFlags
//
//    Resolve
//          This function resolves the shell link, searching for the
//          link if necessary.
//
//          Parameters: [HWND] hwnd
//                          -   The window of the caller (can be GetDesktopWindow()).
//                      [DWORD] fFlags
//                          -   Flags to control the Resolve, from the SLR_ enumeration.
//                      [DWORD] dwRestricted
//                          -   Track Flags to be OR-ed with the ShellLink object's
//                              internal Track Flags (a.k.a. Creation Flags).
//                      [DWORD] dwTickCountDeadline
//                          -   The maximum amount of time, in milliseconds, for
//                              which a search should execute (if a search is necessary).
//
