 |
|
Hello!
How can I execute thread (derived from TThread) ? Execute() method has
already finished, and I would like to execute this thread once again without
destroing and creating object. Resume() doesn't work, and Execute method
cannot be called directly.
thanks
Adam

You don't execute it yourself. It is called automatically when the
underlying thread object begins running.

There is no way to do that. Once Execute() exists, the underlying thread is
finished as no longer running and cannot be restarted.
The only way to do what you are asking for is to not let Execute() finish to
begin with. Change your Execute() code to run inside a loop. At the end of
an iteration of the loop, if the thread has not been signalled for
termination then suspend the thread, keeping it running. When you need the
thread later, resume the thread and let the loop continue, re-executing the
thread's work. In other words:
void __fastcall TMyThread::Execute()
{
while( !Terminated )
{
// do work...
if( !Terminated )
Suspend();
}
}
TMyThread *thread = new TMyThread(false);
//...
if( thread->Suspended )
thread->Resume();
// ...
thread->Terminate();
thread->Resume();
//...
