paint event on picturebox

Hy, 

thank for your code that could be used in some other application.

Next gif shows a VB6 program that (if you pay attention) add point after point of a physical variable:

I can do the same with Visual Studio, the difference is that with VB6 i write only:

form1.PictureBox.PSet (x,y)

With Visual Studio I have to write all the drawing (points). 

Regards
