Not possible to apply Postmessage routine with a thread class in Delphi XE8. No message is processed from a thread methode.

[@BoianMitov]

+Skule Sørmo What do you mean? I use post messages from other thread, although not that often nowadays, and it works in XE8.

[@skulesrmo4986]

+Boian Mitov Works when PostMessage(Form.Hwindow....) is applie instead of PostMessage(Hwindow....) in thread execute procedure, and execute Application.ProcessMessages procedure after each PostMessage procedure applied. PostMessage does not work as showed in the video..

[@BoianMitov]

+Skule Sørmo You should never call Application.ProcessMessages from any thread other than the main thread. And you should avoid ever calling Application.ProcessMessages as it can cause recursive type of bugs, and many other peoblems.

[@skulesrmo4986]

+Boian Mitov Well, have a look at users.atw.hu/delphicikk/listaz.php?id=150&oldal=50 Removing of Application.ProcessMessages in thread implies that the program hangs. It works for me to have it..

[@BoianMitov]

Skule Sørmo I don't see PostMessage in that code. In any case, all my products use the PostMessage mechanism, and as you may have noticed they all work ;-) . Actually it is widely used across many applications. And I never use Application.ProcessMessages ;-) The problems you have may be related with other aspects of the design, such as deadlock ;-)
