Detailed Description

An item in the shell's name space.

All items in the shell's namespace can be identified by a fully qualified pidl. Another way to uniquely identify an item is via it's parent and an item id (i.e., a single item rather than a list). A TShellItem contains a parent (TComRef<IShellFolder> ParentFolder) and the item id (TPidl pidl)

Constructor & Destructor Documentation

TShellItem() [1/6]

owl::TShellItem::TShellItem	(	const tchar *	path,
		bool	throwOnInvalidPath = true,
		HWND	windowOwner = 0 )

TShellItem constructor to make a TShellItem for a file or directory in the file system.

If the throwOnInvalidPath argument is true, an exception will be raised if the path is not valid or if the file or directory does not exist. If this argument is false, no exception will be raised and the Valid() function should be called to make sure it returns true. If Valid() returns false, the TShellItem does not represent a object in the shell namespace.

Parse a display name into a TShellItem (actually, into a TCreateStruct)

ParseDisplayName parses a "for parsing" display name into a TCreateStruct (which can be used to create a TShellItem).

In general, it is not necessary to call this function when using OWL's shell classes.

Note

It is only meaningful to call this function if the TShellItem is a folder; consequently, if this function is called on a TShellItem that is not a folder, an exception will be thrown.

ResolveShortcut resolves this TShellItem (if it's a shortcut) and returns the underlying TShellItem.

Note

IMPORTANT: This function calls CoCreateInstance. Therefore an application that uses this function MUST have previously called CoInitialize (or OLEInitialize).

IMPORTANT: If the shortcut cannot be resolved, this function will return an empty (invalid) item. One MUST check for this by calling IsValid() upon return from this function.
