Hi Graeme (and George Campbell),
George, I don't believe that Graeme's overflow problem is due to VB
changing the ScaleMode to User, but rather it is a bug in VB which was
discovered and reported shortly after the VB forum opened. The bug can be
created simply by using the VB Line command to draw a line which extends
well beyond the border of the picture. This will give an overflow no matter
what ScaleMode is active.
Graeme. Hi. What part of Australia? Beautiful, delightful, Western
Australia or somewhere else?<g> If you use the Win3 GDI functions to do
your drawing, you can avoid this overflow problem. It's more work, but
probably less than having to write your own code to clip complex objects.
Also, the GDI is somewhat faster than VB.
If you need any help with the GDI, give us a shout. I know a little bit
about it and Ted Young knows a *lot* about it.
