Alternative for Postmessage and sendmessage

Question

i have a program which is using several threads to execute some task. Each thread is having a bunch of task to execute. after executing one of them, each thred will call a post

Answer 1

Instead of posting messages, you can put messages in a thread safe queue.

In your main thread, use a timer event to drain the queue.

To remain responsive though, do not stay in the timer event too long.

In many cases I have found this better than posting messages.

In Delphi XE there is a class called TThreadedQueue which you can use.

Edit :

I uploaded a sample sort application utilizing different thread to GUI techniques.

See ThreadedQueueDemo
