Complete noob teaching myself so please bear with me if this is covered somewhere, I really have searched.

I have learned how to populate a field with "chunks" from a different text field. Unfortunately I can only do this when the text field is part of the card I am working on. I have a number of different cards I would like them all to refer back to the same text field on the original card but somehow I can't find the syntax to make this happen.

Example

on mouseUp

set the itemDelimiter to ":"

get item 1 of field "linetest"

put item 1 of field "linetest" into line 1 of field "target"

end mouseUp

This works perfect as long as the field "linetest" is located within the card.
How can I make a button on a different card refer back to "linetest" on the original card?


Thanks in advance for any help you can give.

Hi mgamson,
Welcome to the forum!

You should lookup "name" in the dictionary
Try: "put the long name of this cd" in the Message Box (while you have your stack open).
Every control in LC has a name or ID, if you haven't directly named your Cards then your first card will be "card id 1002" then "card id 1003"etc.. (note: I hope you saw that even the name of the stack came back from the "put" above).

Since every control has a name or id you can address them directly:
"put field 1 of this cd into field 1 of cd id 1003"
Nice huh?
"set the label of button "myButton" of cd id 1003 to "LC is Fun!""

If I haven't been clear just write back.

WOW! brilliant!

Thank you so much. I knew I was missing something obvious. Incidentally after your suggestion, I realized the id number is displayed at the top of each property inspector window.

Thanks again for the quick response

HI MG,

I would highly recommend to give all your objects, cards and stacks meaningfull (= easy to remember!) names
so you do not need to use the IDs

And remember that you can address EVERYTHING with the correct "descriptoir", like:
...
put the text of fld "data entry" of cd "data entry card" of stack "data entry" into tVariable
...
Or even access objects from a substack in a stack that is not open:
...
put the text of fld "data entry" of cd "data entry card" of stack "data entry" of stack "path/to/stack/on_disk.livecode"into tVariable
...


Best

Thanks for the tip Klaus.

I actually had given the object a unique identifier called "linetest" but I could not figure out the syntax to call it up from a different card and it would not call up directly by that name. The IDnumber solved the problem but I could see how this could get confusing to keep track of without descriptive names.

Hi MG,
My quick guess at the trouble is that you have to put the name in quotes, unlike ID.

put field 1 of this cd into field "linetest" of cd id 1003

Like the button example above.

EDIT:
A bit more:
put field "inputLine" of this cd into field "linetest" of cd "theOtherCard"
even more:
put field "inputLine" of cd "inputText" of stack "My First Stack" into field "linetest" of cd "theOtherCard" of stack "mySubStack"

SOLVED !
Just found I'd written 'in card "xxx"', should have been 'OF card "xxx"'
Duh !

If you keep an open mind learning LiveCode can be
a really exciting adventure.
