#806 — Quit from TaskManager

I have 'whipped-up' a quick multitasking application to check my 'Deleted'
SysLog file (AntiSpam deletions) every 5 minutes which opens the file in
the default text editor if it is of more than zero length.

It seems to work OK.

Unfortunately I notice I can't quit it from the task manager.

Does anyone have any hint as to what vital bit I've missed out which allows
this?

The program uses SYS "Wimp_PollIdle" to check every 5 minutes in a
procedure called PROC_pollidle.  Is it that it only returns to be
controlled by the task manager for that brief cycle or three every 5
minutes?

What is your poll (idle) mask?

When you initialise, do you initialise the RO3 way?

If so, what is your list of acceptable message? Is 0 (Quit) one of them?


Best wishes,

Rick.

I assume you're not responding to Poll events 17 and 18 (the user message
ones)?

You should be doing something in your Wimp_PollIdle CASE statement like

  WHEN 17, 18
    IF b%!16 = 0 THEN quit% = TRUE

(assuming that setting quit% to TRUE will cause your app to exit, of
course).  THat way, you exit when Message_Quit (0) is received.

You also need to be careful how you call Wimp_Initialise: passing 310 in R0
is a good idea if you don't want to worry about getting the Wimp to pass the
Message_Quit in to you.

No, that delay is just for the Null polls.  Other events arrive whenever
they need to, as soon as they are sent.

It turns out that my concept of WIMP programming and the required structure
was entirely trousers.

I also failed entirely to handle returned reason codes, so it's not
surprising that I failed to act on the message the WIMP was sending to me!

However, a private tutorial from Rick - always ready to help - sorted me
out.

Thanks also to Steve for spotting the core of the problem, though I needed
a bit more hand-holding.
