Hi Jan,
Many thanks for your very prompt help.
I got the .DLL as you indicated.
Hope to let you know shortly if I have some success with my program.
By way of explanation I've built a quilting machine using servos(clock and dir) ex the parallel port.
Have written all my suite of programs (in QB4.5) to get from CorelDraw to pixel by pixel moves to drive the electronics.
As the traverse speed of of the sewing machine is not fast at this stage I am using the parallel port to provide the
x y & z drive information.
I am in the process of upgrading to VB 6.0 as a learning exercise with a view of achieving better graphics.
I hope that this is not too verbose.
Cheers
