I have a macro in LO BASIC that sets up a dialog, then, instead of

a Cancel button.
hope it helps
Disclaimer: I have never tried or considered what you desire to do,
but..... I suppose that I would first test this (should be easy to do).
This dialog is in my library and I'd like to find a way to set up the
"Cancel" button so it can either stop the script or possibly even
call a clean up routine when it's been pressed - or have it change
the state of a global variable so a routine could see if it's been
I know there are event handlers so I can do something on events like
MouseOver and so on.
And if I were not putting this in a library, I could easily specify,
in the Dialog Settings, which routine to call on Cancel.
But if I want the dialog in a library, is there a way, when calling
the function that sets it up, to specify a routine to call when the
Cancel button is pressed? Or is there some way to create a global
variable or any kind of flag that I could have changed when the
button is pressed?
In other words, other than putting in a "Stop" command, or specifying
one routine name to call when an event triggers it, can I pass on the
name or pointer to a routine that would be called when the button is
First, what is it that you are doing that you desire to interrupt?
Specifically, is it your macro code that is running for a long time,
or, did it make a call that is running for a long time? If it is your
own macro, I would try setting a global in an event handler and check
that global in your code. You could create a quick test
while the "cancel requested global is not true" and two minutes has
do something like add zero to a variable
Print "I am out and finished"
Then, you can check to see if you can set the global variable by
clicking on a cancel button and having the event handler be called. I
am not optimistic that this will work, but, it is worth a try. I am
very interested in your results.
