Create single instance applications linked to
associated file types. When the associated file is
double clicked it will be handled by a single
instance of your application.

This lets your application act like Media Player
rather than Notepad. Each time you double click a
media file Media Player does not open a new window
but re-uses the existing one.

This is normally difficult to achieve in Visual Basic
but the OneOnly control makes it simple and also
allows you to create the associations between file
types and your application.

Extending the association allows you to add items to
the right click pop-up context menu for your
associated file types as well.

ActiveX control for VB6.
