And that was to help you learn to do things for yourself, not to get someone else to do it for you. Read your course notes.
my teacher only introduce what is Bspline and give this exercise to me... each student in my class is the same. they have another exercise, different from my exercise , ex: use surface to draw a face, draw a car by benzier curve... it is realy hard.... all informations i must find out help me... thank you very much.

Just press the left button and move the mouse following a BSpline shape (remember to choose the pen tool). :-D

Please read the posting guidelines. There's even no clear question in your message. You don't believe that somebody here will just provide you with the code, do you ? Ask a precise question. Explain what you have tried and where you are stuck exactly.

GDI has a function called
PolyBezierthat can be used to draw b-splines.«_Superman_» I love work. It gives me something to do between weekends.
