I have a number of questions regarding lines in Mappoint.

I have no trouble drawing them from the points I want (programmically), but I do not want the user to have the ability to move and or delete them.
I really would like to create "something like a read only" line.

In addition, is there any way to know which line the user has selected? For instance Program draws a line between Milw and Chicago. Program draws another line from Miami to Orlando. User clicks on the Orlando line, in VB how do I know?
