I want this code to eventually compare full screen-captures, so if there is any way to speed it up, I am open for advice.
Take out the progress bar and then see how it does. Setting a progress indicator on every repeat often takes longer than running the entire rest of the handler.
If you do need a progress bar, only update it occasionally; for example, every few hundred iterations:
if c mod 500 = 0 then set the thumbpos of sb "progress" to c -- Jacqueline Landman Gay | [email protected] HyperActive Software | http://www.hyperactivesw.com _______________________________________________ use-revolution mailing list [email protected] Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
