Is there an ON EXIT run sub/function?

[xra7en]

Hi
Need to do a little app cleanup if a user clicks the "X" vs regular "q"uit etc.. In my case, I want to execute a "save_game" funciton even if they just "x" out of the app

VB5,6 have this, just curious if qb64 does :-)

THIS I know. I need a function/sub to run if they click the "x" (and not a "Q"uit option )

However, it will NOT run a sub or function if a user clicks the "x" on the terminal window. the terminal window will just stop.

For example clicking the red "x" in firefox, it will run some cleanup and delete cookies etc...

a qb64 window will just exit/end

edit: I know the title is confusing but there was not a better way to write that
I need the "exit/end" to RUN a sub/function

You'd use the _EXIT command in your main loop to check for the exit condition.


DO
    count = count + 1
    PRINT count
    IF _EXIT THEN RunExitSub

   _LIMIT 30
LOOP

SUB RunExitSub
   PRINT
   PRINT "Closing files and stuff...."
   _DELAY 5
   SYSTEM
END SUB

o interesting!

did not think to check for _exit LOL, actually did not know I could

I'll give it a shot.

OK, that's a little tricky. it's not just ANY loop, if you have an inkey$ loop, I have to put it there. Had it in the main loop and it did nothing.

I wonder if you might need it everywhere a loop might run? It's like an event.

In that case, set an ON TIMER event to check it every half second or so.
