whenever the user clicks on the Open button.

OpenFileDialog is a sealed class,so you can’t derive from it.
However,if you want to customize the behavior of a file dialog,to
the extent that it is possible,you should create a brand new class
deriving from the abstract class FileDialog. In this case,you have
access to a couple of powerful but protected methods such as HookProc

o.OpenDialog.ShowDialog();
o.Reset();
