Polygon API Function

I am on that since this morning.
Sometimes it draw corectly my polygon, but in 90% it does not
work even if it's EXACTLY the same instructions !!!!!!

Giving "those" instructions could have been better !

May be it got something to do with ScaleMode property of Form/Picture box on which you are drawing. Most API fns assume pixel mode. So change to VbPixels mode and try.

or post that code.........

i found it last week

changing

type PointType
x as integer
y as integer
end type


by long variable x as long and y as long.


do not ask me why

Did you copy the POINTAPI structure from VB4 16bit ? or did you convert it from the original C header ?

A M$ C int is a 32bit integer - which is a Long in Visual Basic.


By the way - if you're interested in doing some fast polygon programming in VB, take a look at :
