How to animate a line

My problem is to animate a line, a line starting from a point and progressively increasing in length over time. I cannot achieve this using the draw methods in flash. Because when using these methods to draw the line the results occur in a “Flash”.

What I want is the line to grow from a point A to a point B slowly in a smooth fashion.

Any suggestions?

Thanks for all the help

Cure :skull:

This is really cool. How would you convert it to make it where it connects to a movie clip when the movie clip is clicked?
