vb.net - close a form without using invoker method? -

-

hi have main form has several mdi forms . have user authentication check if users given rights mdi form . happens on form load , if user not have rights close. wanted ask wether there method other invoker method.

 me.hide  me.begininvoke(new methodinvoker(addressof me.close))

since interface mdi, assume you're using menu or button, @ least click event, open form. put authenmtication in click event handler before open form, , if authentication fails notify user of instead of opening form. not more efficient use of resources, more secure since system lag leave information on form visible before closed.

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.
