Slow Painting

[Brian P. Hammer]

All - I have a form with a tab control. On several of the tab pages, I have
user controls with 50+ controls - A label, textbox and checkbox * 17. Each
time the tab page is selected, you can see each label, textbox and checkbox
drawn on the form. I have set doublebuffered on each item. How can I set
the user control not to show until all items are drawn on the control?

Thanks,
Brian

Double buffering is probably slowing things down. Child controls paint in
their own windows and so double buffering a parent will have no effect other
than to make the parent draw more slowly. Double buffering all the controls
will make them all draw more slowly.

Thanks Bob. I turned off double buffering and also built a release and ran
outside of the IDE. That speeds things up considerably.

Thanks,
