Hi,
I'm developing and application that read a stream from serial port,
trasform byte in a structure and send it to the top-most dialog that
uses those data. When a frame is received I create (new) my structure
and send with a postmessage to the top-most dialog (it delete the
message too). What happen if I close the dialog before all messages
are elaborated ? Is there a way to wait until all messages are
processed ? How can I prevent leakage if some messages weren't
elaborated ?
Thanks in advance,
Stefano
I assume that the messages are posted from a secondary thread? If you pass
any reference (like pointer, HWND) to a secondary thread then you must
assure that these items remain valid until the thread exits. If your dialog
can close before the thread exits then the design is wrong. You could
either make sure the dialog closes the thread before it closes itself, or
you could change the PostMessage to go to some other window that is certain
to live longer than the secondary thread.
