Extending a File Dialog

[Stuart]

I'm looking to implement a Standard File Open Dialog, and put a little File
Preview segment onto the dialog. Unfortunately it's not as straightforward
as just inheriting a regular file open dialog and adding the bits I need.

Does anyone know of any easy way to achieve what I'm looking for? Or will it
be a case of me having to write a whole new dialog from scratch?

Many thanks

Stuart

Hi,

IIRC OpenFileDialog is declared as sealed, therefore you cannot extend it,
now I do remember reading some article ( I found it );

Stuart... Can't you make use of the various Protected methods - such as
HookProc and especially OwnerWndProc?
