Outlook Calendar Selection

[usabmaster]

Hello!

I am trying to create an holiday planner, which relies on the
appointment technique. So far I created a button to open the
appointment form with some pre-defined parameters.
But now I have the problem to get the information of the selection in
the calendar. For example: marked from 9.30 to 15.30. Then press the
button to open the form. But how can I get the information of the
selection into the form?

Another question: how can I add "new holiday" to the right-click-menu
on the calendar. the menu bars are no problem, but the context menu
is.

Thanks for any help in advance.
