vb.net - How do delegates solve cross-threading issues? -

-

i know can't call gui update function background thread, yet can't see how creating delegate, assigning gui update function it, , calling solves problem. how different calling gui update function itself? how creating function pointer (delegate) solve problem?

delegates not solve problem, control.begininvoke() or dispatcher.begininvoke() methods do. know how run code on specific other thread, feature provided message loop (aka dispatcher loop) ui thread uses. such loop common solution producer-consumer problem.

these methods require delegate object, passed argument. know specific code needs run on ui thread.

Does Firefox offer AppleScript support to get URL of windows? -

-
i trying write applescript that, among other things, gets url of every open webpage in firefox. in safari (and chrome), done simply: tell application "safari" return url of every tab in every window however, seems me firefox offers no real applescript support, such getting url of tab or window. when google terms "firefox" , "applescript" together, firefox bug requests asking applescript support restored, last updated in 2010 or 2011 (like this , this ). am right in thinking, then, firefox no longer offers proper applescript support? realize there semi-workarounds, such simulating key-commands in applescript, aren't practical purposes. to see of applescript commands firefox responds to, launch applescript editor, select menu file > open dictionary... , , choose firefox application. you'll find you're expecting: firefox doesn't offer useful applescript commands.
