Hallo, I have the following problem with the Thread: I create the Thread first as SUSPENDED, but it does not start at the expectetd time. First the Program calls this function: ThreadStart(); /////////////////////////////// ThreadStart() { if (m_pSelThread != NULL) { if (::WaitForSingleObject(m_pSelThread->m_hThread, 0) != WAIT_OBJECT_0) return; delete m_pSelThread; m_pSelThread = NULL; } ::WaitForSingleObject(m_SEl_Start_Event, 0); m_SEl_Start_Event.SetEvent (); // CEvent Object CWinThread* m_pSelThread = AfxBeginThread(ThreadFunktion, this, THREAD_PRIORITY_NORMAL, 0, CREATE_SUSPENDED); m_pSelThread->m_bAutoDelete = FALSE; m_pSelThread->ResumeThread(); } UINT ThreadFunktion ( LPVOID param ) { if (param == NULL) return -1; DoSomeThing(); return 0; } The Thread does not come to the UINT ThreadFunktion(LPVOID param). Any help would be appriciated.

Shouldn't that be:
m_pSelThread = AfxBeginThread(ThreadFunktion, this, THREAD_PRIORITY_NORMAL, 0, CREATE_SUSPENDED);
i.e. you're hiding the class member variable with the local one. :)

What is the purpose of the above call? :)

Can't you just start the thread and wait for the event to happen within the thread before executing code? What's all this mess about? Why are you setting the
m_bAutoDeletemember to false? I see you may delete it manually, but *what* is the purpose of it?It is a crappy thing, but it's life -^ Carlo Pallini

That doesn't make sense. Anyway I made a test on my system: Without hiding the class member variable, the thread starts happily. :)

the thread mus t be created but not start immediately, autodelte false to tell him not to delet himself.
So, why should it not start immediately? Can't you just start it immediately, but not execute any code until the interested event happens? I asked for the reason behind your approach. I did not ask you what
m_bAutoDeleteis for. Tell me why do *you* want the thread not to delete itself.It is a crappy thing, but it's life -^ Carlo Pallini

Well you may want to do that, I mean that's nothing wrong in doing it (and that's the reason for delaying the thread start). :)

No, I asked why did he want to delete it manually (as opposed to leave it die in its way). There could be valid reasons, I wanted to know the OP's reason. :)

You're right: there could be valid reasons, anyway you're very (and, of course, politely) curious about her reason. :rolleyes:

Of course, politeness is guaranteed (or 100% money back), after Mr. Maunder's new commandment. :)

:-D BTW there's a polite way to advice someone to stop using threads? :rolleyes:
