// IBriefcaseStg Interface
|
||
|
|
//
|
||
|
|
// This is a private interface for use between the shell and the briefcase.
|
||
|
|
//
|
||
|
|
// This interface is used by the Shell's IShellFolder implementation
|
||
|
|
// when it is bound to a folder that is (in) a briefcase. The IShellView
|
||
|
|
// of the particular folder binds to this interface to open the briefcase
|
||
|
|
// database storage and optionally make modifications. File-objects that
|
||
|
|
// are added to a folder in a briefcase are not added to the storage
|
||
|
|
// database until IBriefcaseStg::AddObject is called. Keep in mind the
|
||
|
|
// difference between IBriefcaseStg and IShellFolder. IBriefcaseStg
|
||
|
|
// simply provides access to the briefcase storage database--the file-system
|
||
|
|
// objects are only affected upon subsequent reconciliation using
|
||
|
|
// IBriefcaseStg::UpdateObject, unless otherwise noted.
|
||

// IBriefcaseStg::Initialize(pszFolder, hwndOwner)
|
||
|
|
//
|
||
|
|
// Initializes the interface by specifying the folder for this storage
|
||
|
|
// instance. If the folder does not exist somewhere in a briefcase
|
||
|
|
// storage hierarchy, then a briefcase database is created for this
|
||
|
|
// folder.
|
||
|
|
//
|
||
|
|
// IBriefcaseStg::AddObject(pdtobj, pszFolderEx, uFlags, hwndOwner)
|
||
|
|
//
|
||
|
|
// Adds a file-object(s) to the briefcase storage. This function also
|
||
|
|
// performs an update of the specific files to immediately make them
|
||
|
|
// up-to-date.
|
||
|
|
//
|
||
|
|
// Typically pdtobj refers to a file-object(s) outside the
|
||
|
|
// briefcase. Calling this function implies adding the object(s) to
|
||
|
|
// the briefcase storage database in the folder that was specified by
|
||
|
|
// IBriefcaseStg::Initialize(). This rule holds unless pszFolderEx is
|
||
|
|
// non-NULL, in which case pdtobj is sync-associated to pszFolderEx
|
||
|
|
// instead.
|
||
|
|
//
|
||
|
|
// AddObject() returns NOERROR if the object(s) were added. S_FALSE
|
||
|
|
// is returned if the caller should handle the action (eg, moving
|
||
|
|
// files from folder-to-folder within the briefcase).
|
||
|
|
//
|
||
|
|
// IBriefcaseStg::ReleaseObject(pdtobj, hwndOwner)
|
||
|
|
//
|
||
|
|
// Releases a file-object(s) from the briefcase storage database. This
|
||
|
|
// does not delete the file from the file-system.
|
||
|
|
//
|
||
|
|
// IBriefcaseStg::UpdateObject(pdtobj, hwndOwner)
|
||
|
|
//
|
||
|
|
// Performs a file-synchronization update to pdtobj. If pdtobj refers to
|
||
|
|
// the root of a briefcase storage hierarchy, the entire storage is updated.
|
||
|
|
//
|
||
|
|
// IBriefcaseStg::UpdateOnEvent(uEvent, hwndOwner)
|
||
|
|
//
|
||
|
|
// Performs a complete update of the briefcase storage based on the
|
||
|
|
// indicated event. The event ordinals may be:

||
|
|
//
|
||
|
|
// UOE_CONFIGCHANGED Indicates a PnP DBT_CONFIGCHANGED message wants

// IBriefcaseStg::GetExtraInfo(pszName, uInfo, wParam, lParam)
|

//

// Gets some specified extra info from the briefcase storage. The

|

|

// null-terminated string, where the first is the old pathname, and the
