C# Class JWC.MruStripMenu

Represents a most recently used (MRU) menu.

This class shows the MRU list in a popup menu. To display the MRU list "inline" use .

The class will optionally load the last set of files from the registry on construction and store them when instructed by the main program.

Internally, this class uses zero-based numbering for the items. The displayed numbers, however, will start with one.

ShortenPathname ( string pathname, int maxLength ) : string	Shortens a pathname for display purposes. Shortens a pathname by either removing consecutive components of a path and/or by removing characters from the end of the filename and replacing then with three elipses (...) In all cases, the root of the passed path will be preserved in it's entirety. If a UNC path is used or the pathname and maxLength are particularly short, the resulting path may be longer than maxLength. This method expects fully resolved pathnames to be passed to it. (Use Path.GetFullPath() to obtain this.)
