winforms - ThreadPool.QueueUserWorkItem new Form CreateHandle Deadlock -

-

i have thread needs create popup window. start thread using threadpool.queueuserworkitem(new waitcallback(createpopupinthread)) thew thread creats new form. application freases in new form constructor @ createhandle. worker thread locked... how can fix this?

this how create form 

var form = new confirmationform                            {                                text = entry.caption,                                label = entry.text,                            };

in constructor thread enters deadlock

public confirmationform()         {             initializecomponent();         }

i think better create "popup window" on ui thread , create thread in "popup window" process want do.

as suspected, can´t show form created on non ui thread.
see answer: possible construct form on background thread, display on ui thread

(or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
