Visual links between items/links


I want to make a program with some visual links (relation) between the
records/items of two tables/listboxes.

A line/arrow should be drawn between the two tables/listboxes and it
should be possible to move these lines in run-time.

So, you could do me a great favor by sending me examples or ideas about
- drawing lines between controls
- resizing/moving these lines
- ...

Thanks in advance
