Segments

Hi all.

Within as form I have a sub that draws segments that go to make a pie chart,
The sub has these args:
R As RECT
StartPercent As Single
EndPercent As Single
TheColour As Long
TheHDC As Long

So- if I had the code:
DrawSegment R, 25, 58, vbRed, Me.Hdc - then a red one third segment would be
drawn on the form.
All works well.

Question 1:
How can I find out the X & Y (in pixels) of the two points of the segment on
the diameter of the circle.
Question 2:
I would like to have a tooltip that says what the sement is representing
when the mouse is over the segment. But how would I know when the mouse
cursor is over the segment.

Any ideas would be appreciated.

Thanks

Ivar
