Can't delete this stack? - Livecode - livecode

Question

I create new stack from mainstack and after I want to delete mainstack.
I can't it.
Here my code:
create stack "newstack"
go to stack "newstack"
delete stack "mainstack"
How do I do?
Thank you

Answer 1

Try this:
local tStackID
put the long ID of this stack into tStackID
create stack "newstack"
go to stack "newstack"
delete stack tStackID
That seems to work in a simple test.

The reason for the inability to delete the stack is probably the fact that a script of your main stack is still running. Try to send a message to the new stack. That way, no script in the old stack will be running when it is time to delete it.
on createNewStack
local myStackID
put the long ID of this stack into myStackID
create stack "newstack"
go to stack "newstack"
send "deleteOldStack myStackID" to stack "newstack" in 0 secs
end createNewStack
on deleteOldStack theStackID
delete stack theStackID
end deleteOldStack
Call createNewStack from a mouseUp handler for instance. Put the createNewStack in the same button, card or stack as the mouseUp handler (if you put createNewStack at stack level, you can put the mouseUp handler at button level, but they have to be in the same stack).
Put the deleteOldStack handler into the new stack at stack level. It will run when the script in the old stack finishes running.

Answer 3

Perhaps you are confusing the removal of a stack from memory, and the deletion of a file from the machine.
The first is indeed invoked as you wrote, using the "delete stack" command.
The second would require the use of the "delete file" command, appending the appropriate pathname.

Answer 4

If the code that removes the stack is inside an object or sub-stack, I think it must give an error. So you can try something like creating a stack and putting a code to that stack that is the one that removes the mainstack. Example:
on mouseUp
    local tStack
    put the long id of this stack into tStack
    create stack "NewStak"
    set the script of stack "NewStak" to "on deleteMainStack; delete" & tStack & "; end deleteMainStack"
    send "deleteMainStack" to stack "NewStak" in 0.1 sec
end mouseUp
Please note that when creating a substack this is part of your mainstack. So if you delete the mainstack it deletes all its substack. The above code creates another mainstack and deletes the one I call it. One way to delete the minstack of a substack is to tell it to merge into its own mainstack and then to delete the previous one. Remaining the same only in memory and not in the disc, since the filename property is substack it as that of its mainstack.
