outlook c# add-in

[Chris Millar]

I have created a com add-in using c# that is a custom command bar button
displayed in the standard toolbar.

I wish to add an action to the button so that when clicked will open the
contacts form. I have the event handler for the button click all that i
need is the sample of how to load a contact form when clicked.

how is this done?

thanks in advance
