Adding custom controls to a forms.

[Jose]

I want to add a custom control (generic .dll) to a custom Outlook form such as the meeting built-in form .Of course in a new page
My question is wich features may have my control (dll) to bind to an item properties .As you can image, I need to store the value of the control.This control is a visual drop-down calendar, in which you can select the date (month) ; so I need to store this date in an item property

Other question : Can I get this control dll ?

Thanks a lot , jose .
