Bézier Curve... how?

[Q_Me]

With given coordinate index how can a Bézier curve be made in VB using a standard picture box to plot the points?

eg.

Sub BezierThis(NumberofPoints as integer, TheseXY() as POITAPI)
For i = 0 to NumberofPoints - 1
 DoSomething
 pic1.pset (curvepoints), vbBlack
Next i
End Sub

Any ideas?
