SS 3.0 Autoscroll question
Hi:
When Autoscroll is checked, pieces of the log flash by in the log window. When Autoscroll is unchecked, the log scrolls slowly and readably.
1. Shouldn't it be no scrolling (last portion of log viewed) when unchecked?
2. When it's scrolling (Autoscroll unchecked), is the whole scraping session thereby slowed down to allow reading of the current results?
TIA

Todd:
Yes, it is a function of the view pane, as you mention. I finally figured it out.
When autoscroll is checked, the view is at the bottom of the log, where the most recent lines are posted. There is a considerable amount of jerkiness to the screen update if there are, say, 1000 lines in the buffer. It doesn't look like anything like "scrolling", since it is making the screen repaint entirely visible.
When it's not checked, you're looking at the end of the buffer before it scrolls out. You don't realize this, though, since here it is scrolling regularly a line at a time. But all the current posts are below off-screen, and you don't see them. It is very confusing if you don't realize this.
Thanks for your help.

Hi,
It will actually depend on when the "auto-scroll" box is checked, and how many lines you've designated to view in the log. If the "auto-scroll" box is checked screen-scraper makes sure the view port on the pane is always scrolled to the bottom. In some cases, though, that will just happen naturally because of when the box was checked, where the scroll bar was at the time it happened, and how many lines are to be viewed.
Regarding the slowing of the session, my experience has been that it seems a bit slower when the box is checked, simply because the GUI needs a bit more CPU in order to ensure it's updated correctly. Either way, when the session is run in a production environment (which should be from the command line or in server mode), the logging will have almost no impact on the speed.
Hopefully this helps. Let me know if I can clarify.
