Flood fill...

Hi,

I'm trying to do a "fill" function in a drawing app. using a picture box.
Has anybody an idea how to do that?

Thanks, Claude.

Humm.
I think my question was not very clear:(I'm french, sorry)
The fact is that I can only fill circles and rectangles with the FillColor and FillStyle property of a PictureBox, but not a custom shape. That's what I'm trying to do.
Or if someone has some code (or link) to make a little drawing application, I would appreciate.

Thank you.
