Something new for Visual Basic developers!

Integrating Lotus Domino with Visual Basic or VBA applications is brain-dead
simple with the brand-new Domino Collaboration Objects. These are a set
of COM components that appear on the Visual Basic toolbar and allow developers
to instantly add Domino integration into their applications. Developers can
add true collaborative features to their business applications such as email
notifications, workflow process automation, calendaring and scheduling functions,
and viewing Notes/Domino information inside their applications.

As an added bonus, the Domino Collaboration Objects are free of charge and
OPEN SOURCE!
