Re: Measure point to point

Hi Peter,

Thanks for the great tip and I am able to make some reasonable progress
on it. I am still searching for a way to draw a line between 2 points that
will show the measurement.

Basically none. You can do this by creating a full screen empty form
(Borderstyle bsNone, all Bordericons set to false, Windowstate set to
maximized) that is transparent (or shows a bitmap image of the full
screen in its client area). You can fake transparency easily by setting
the forms Brush.Style to bsClear in the forms OnCreate event. The form
then simply does not draw anything, so the previous background appears
unchanged. The form will get mouse events, though, and you can draw on
its Canvas (use an xor pen to be able to erase what you have drawn, if
needed).

Search the newsgroup archives for "unit PBCaptureFormU" as a phrase,
that should turn up an old post of mine that shows the technique.
