Control Inheritance?

My question for the day is :
How can I do multiple inheritance?

I created a Party control which is a group box with labels,
textboxes, and some functionality...AND I want to inherit this
control into a new control which is a form and create a new
control with the form and a menu. BUT since the form already
inherits System.Windows.Forms.Form it will not allow me to inherit my control. ANY SUGGESTIONS? ;)

Public Class ctlPartyForm
Inherits System.Windows.Forms.Form
Inherits ctlNODlib.ctlParty
'DEVELOPMENT TIME ERROR: 'Inherits' can appear only once
'within a 'Class' Statement and can only specify one class.
End Class

THANKS IN ADVANCE!!!
