Application is locked here (onterminate is called in locked state).

but does it successfully if called at end of OnExecute.
If you want to be refreshed by waitus() in onterminate do
application.unlock;
waitus(100);
application.lock;

How do You debug threaded apps ? Open the thread window, select the thread you want to debug. Linux gdb works better for debugging threads then the Windows version. Sometimes 'Project'-'Options'-'Call GUI_DEBUGBEGIN/GUI_DEBUGEND must be activated in order to prevent gdb crashes. For evil apps it also good to restart GDB after app run :) ( todays' experience ) PS: ExitCode+Terminate work excellent. -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

Probably. There will be an immediate abort of the program without calling finalize routines. Unit's finalization is called.

Which are conditions of terminating (finishing) thread ? 2012/7/24, Ivanko B ivankob4m...@gmail.com: Set the global variable ExitCode and set application.terminated to true. = This looks as a solution. 2012/7/23, Sieghard s_c_...@arcor.de: Hallo IvankoB, Du schriebst am Mon, 23 Jul 2012 17:02:02 +0500: PS: Since me still can't get proper threading mechanics, Me have dead lock in my application. Did you make sure that all ressources are reserved strictly in the sme order everywhere they're used? Requesting ressources in varying order is a sure method to create deadlocks: A: request Ra, request Rb B: request Rb, request Ra If the order of processing is A:Ra, B:Rb, then you have it. Try it with B reqesting the other way, and see if you can create a deadlock that way. Then you can proceed to more complex scenarios. ;-) -- (Weitergabe von Adressdaten, Telefonnummern u.ä. ohne Zustimmung nicht gestattet, ebenso Zusendung von Werbung oder ähnlichem) --- Mit freundlichen Grüßen, S.
