I need a line control that raises events for Click, ConnectEndPoint, etc. The Line control that is intrinsic to VB does not notify you when a user selects it. The project I'm doing allows users to connect boxes. When they select a line, I want to show the hotpoints, and allow them to delete the line. For the hotpoints to show, I have to receive a select event. Then I can draw little boxes or circles at the ends and in the middle. When the user connects an endpoint with a another control, I will show the line being connected by maybe changing the connection point to green.

Similar to how it works in Visio. But I don't want to do this inside Visio, or with the Visio object model.

That sounds rather complicated. Are you sure you shouldn't implement this yourself? Take for example intersecting lines... And most controls have square hit-boxes.
