The FileChooser is the event observer of the frmChooser object. When
frmChooser raises its "Change" event, it is catched by frmChooser_Change().
Then the "Change" event of FileChooser is raised, and this event will be
catched by a possible "xxxx_Change()" event handler in the parent object of
FileChooser.

{...} tells the compiler that a symbol is an identifier, and must not be
interpreted as a reserved keyword.
It's funny, because I took this syntax from Visual Basic, and that question
comes frequently. :-)
