Well,
I also consider it Unlikely, but that is what both Concept mistakes and stupid Bugs are made of.

The Tick Messages are sent to the Application. The Application has a List of Structures, consisting of: the hWnd of the Dialog, the Default TimeOut, and the Current Count. Upon every tick the Top Count get decremented, and, when it reaches 0, a Registered Windows Message, WM_REG_TIME_OUT is sent to all Dialogs, in Sequence. The CTimedDialog primitive answers to this by a virtual OnDlgTimeOut(), which by default ends the dialog by OnEndDialog(IDABORT). If the Dialog ends for "Natural" reasons, the EndDialog() of CTimedDialog Pops the reference to the Top Dialog of the list, and resets the Current Count of the new Top Object to it's Default value. I have used a CRITICAL_SECTION where needed, but did not go over the top with belts and braces.

The Time-Out bar on the dialogs is more of a debug feature than anything else. It assures me that the clock is ticking, and that things did not deadlock.

Thanks for giving me the foothold for assuring me that I am not doing something fundamentally wrong,as other books and autors seem to suggest. (NEVER mix a Worker and a GUI Thread) my Concept is at least not wrong in your judgement. I Start looking for a stupid mistake somewhere.

Timed and Activity based actions are notoriously difficult to debug.

Stupid Mistakes, (and I made many in the past 60 odd years), are the most difficult ones to find.
I'll let you know when I discover what went wrong. I also think that when I get it right, that the subject is of sufficient interest to merit an article.

Regards, Smile | :)
