Are There No Thread Messages?

[Gary Beene]

In one of the PB sample apps, a user-defined message is generated when the thread completes.

Are there no messages automatically sent to a dialog when a thread is created or when it closes?

Here's the relevant segments of code from that application.

%CM_THREAD_COMPLETE = %WM_USER + 1

    Case %CM_THREAD_COMPLETE
      Thread Close hThread TO hThread
      Control Enable CB.Hndl, %ID_BTN_CALC

Function PrimeThread(BYVAL hDlg AS LONG) AS LONG
  Dialog Post hDlg, %CM_THREAD_COMPLETE, 0, 0
End Function

Um, what if the application has NO dialogs? How about if it has twenty-seven dialogs?

However when a thread function ends, the thread object is signalled. This means you could automatically detect a thread function's termination by modifying your message loop to use a MsgWaitForMultipleObjects() call... which of course means you'll have to change to a modeless dialog or regular window, since you don't have access to the modal dialog's message loop.

Ok, so the short answer is: "No."
