yes I found the formula for straight lines and I was wondering what was the one for bezier curves, so your reply could not have come a better moment. Thanks I will study it and implement it.�

Hello,

You may want to calculate the distance between the mouse position and
your path (I guess a bezier curve). Then given this distance and a
tolerance to zero you decide if the mouse position is more or less on
your path. Calculating the distance you will also get for free the place
where to add a point on your path.
