here the script that will not remove a card:
Code: Select all
command verwijderkaart
answer "remove card selected: hit OK"&cr&\
"not yet selected: hit Cancel, select card, after that hit OK" with Cancel and OK
if it="OK" then
put selectedtext of fld index into tSLT
put lineoffset(tSLT,fld index) into tLO
else
break
end if
go card tSLT
delete this card ----------errormessage, see below
sort lines of fld "index"
end verwijderkaart
errormessage
stack "NAW": execution error at line n/a (Object: stack locked, or object's script is executing)
As far as I may understand I remove the line "go card tSLT": now the errormessage is:
"stack "NAW": execution error at line 31 (Chunk: can't find card), char 4
But card tSLT is still there
What's wrong

Hi.
Have you tested this by stepping through the handler? I am thinking that maybe the reference to the card in field "index" may not be valid, and that there is no card to delete. If you step through, you will see if your navigation really sent you to the right place.
Not sure about this, but do check...

I did: nothing abnormal.
Suddenly I rememerd another stack, where it worked fine (thanks to Klaus).
I copied it.
Bingo.
Thanks anyway, Rob

It may not be related to the problem you had originally, but please please get into the habit of putting quotes around object references. They are *not* variables, ie
Code: Select all
put selectedtext of fld index into tSLT
should be
Code: Select all
put the selectedtext of fld "index" into tSLT

Hi Rob,
the error dialog is correct: You cannot delete a card where an object's script is currently executing!
Do something like this:
Add a new handler to your stack script:
Code: Select all
command delete_card the_card
delete card the_card
end delete_card
Then in the handler "verwijderkaart"
Code: Select all
...
## User a littel delay to give the script the time to finish.
## We use the card number as a paramer for the new handler
put the number of this cd into tNumber
send "delete_card tNumber" to me in 100 milisecs
sort lines of fld "index"
end verwijderkaart
Best
Klaus
P.S.
No need to change your lifestyle, change the way you think and script!

Hi Kluas,
for the moment there is this script in the menubuilder:
Code: Select all
case "deletecard"
global tLO,tSLT
answer "te verwijderen kaart al geselecteerd: klik op OK"&cr&\
"kaart nog niet geselecteerd: klik op Cancel, selecteer de kaart en klik daarna op OK" with Cancel and OK
if it="OK" then
put selectedtext of fld index into tSLT
put lineoffset(tSLT,fld index) into tLO
send "delete_card" to this stack in 1
end if
break
and in the stackscript:
Code: Select all
command delete_card
global tSLT,tLO
delete card tSLT
delete line tLO of fld "index"
end delete_card
This works well. Any reason to change ?
