Many thanks to several people who gave me info about creating buttons on
the fly. It works nicely. I have another beginning HC programmer question.
If I have a script attached to the openStack event, and I screw it up badly,
i.e. I have an infinite loop, is there any way to get to the script to fix it?
After you get done laughing, if you have any suggestions I'd appreciate them.
Thanks,
Jamii

To fix the error in the openStack handler (assuming it is in the stack
script) you should be able, with any other stack (like home) open, to
just enter via the message box:
edit the script of stack foo

(using HC1.2) I would like to create a script which simply allows me to use the select tool to erase an area. I can't figure out how to cut or erase the selected area. The script should read something like this: choose select tool drag from 100,100 to 100,200 ?????? choose browse tool Can anyone fill in the ????? I've checked through Goodman's book and also looked through Apple's HyperCard Script Lan- guage Guide. Much appreciated. Lou Rosenfeld

Please note that "Clear Picture is only available as a menu option when a valid selection has been made; "drag from 100,100 to 100,200" encloses a rectange of zero area, so no selection is made. Something like "drag from 100,100 to 200,200" works fine. -- Bill Johnston (johnston@oscar.ccm.udel.edu) -- 38 Chambers St.; Newark, DE 19711; (302)368-1949

I had to do this in a keydown handler in order to distinguish upper and lower case letters. Hope this helps, Keith Conover. ireland@ac.dal.ca

I want a button to disappear when a field is empty and appear the
instant a user types a character into it. My code looks like this:
on keyDown theParm
send "keyDown" && theParm to this card
if me is empty then
hide card button "button"
else
show card button "button"
end if
end keyDown
It works fine, except when the user types a space. Then the message
gets confused. What gets passed is probably "keyDown " and the second
space isn't interpreted as the key. Is there a good way around this?
I'd like to avoid any hacks.

Any ideas how to fix that problem too? Jim

One solution to both problems is to time the hiding/showing of the button until
the enter key is pressed, ie when you have finished entering text in the field.
The script in the field could be something like:
on EnterInField
if [card] field <fieldname> is empty then
hide [background] button <buttonname>
else
show [background] button <buttonname>
end if
pass EnterInField
end EnterInField
This is a fairly simple answer, and may not be quite what you need; however,
since you presumably wouldn't want to press the button until you've finished
entering text, it shouldn't be a problem from that aspect.
Hope it helps!
