Use the Line method and set the Forms DrawStyle property to vbDot.
Me.DrawStyle = vbDot
Me.Line (X1,Y1) - (X2,Y2)
To Draw a Solid Grid contour line, use
Me.DrawStyle = vbSolid
Me.Line (X1,Y1) - (X2,Y2),,B
Some restrictions may apply: if you set DrawWidth to a value different from 1, it will be ignored. _________________________________
