Initializing Number Fields on Startup

[CodeTRUCKER]

How do I initialize various fields when a LC application is executed? Here is what I tried, but I don't get any results...

(open the stack, "stkMain")

Code: Select all

put 0 into GroundSpeed

(the text box, "groundspeedbox" does not show a "0" like it is supposed to)

Please help.

Hi CodeTRUCKER,
Welcome to the forums!

put 0 into GroundSpeed

You have not told the engine the container type you want to put it in. Right now it's thinking GroundSpeed is a variable.

Here is a lesson that should help:

Thank you for the welcome, Simon!

FYI - "GroundSpeed" is a variable. [Calvin scratches head as he makes his way to the lesson...]

Hi Calvin,
Ahh I see, you haven't made any link between groundspeed and groundspeedBOX
Sorry I read it too quickly the first time.

Hi Simon,

Code: Select all

put 0 into GroundSpeed
put GroundSpeed into GroundSpeedBox

Nope, still not working. I have read the page 3 times including reading it last night. I'm just not "getting it."

Take Two!

[Simon]

OK...
What is groundspeedbox?

Code: Select all

put 0 into GroundSpeed
put GroundSpeed into GroundSpeedBox

You will have to tell liveCode what it is... errr... groundspeed we know is a variable, right now liveCode thinks groundspeedbox is one as well.

Ah! You mean something like...

put 0 into GroundSpeed
put GroundSpeed into textbox(GroundSpeedBox)

I have looked for several hours since last night trying to locate *how* to read and wite into text fields. No joy yet (which is why I posted). It may take a while before I learn how LC does what.

Hi Simon,

Not a good idea (for me, at least). I get very confused easily if there are numerous things going on at the same time. Please let me continue this subject in this thread, if that is OK?

[CodeTRUCKER]

Moving on...

Do I have to structure it...

Code: Select all

put 0 into GroundSpeed
put GroundSpeed into GroundSpeedBox

Or can I just code it like this...

Code: Select all

put "0" into field GroundSpeedBox

Seems like the second one would work?

[Simon]

Yup. but quote the fields name

[CodeTRUCKER]

Yup. but quote the fields name

I tried...

Code: Select all

put "0" into field "GroundSpeedBox"

..., but it still doesn't work. I feel like an idiot.

[Simon]

Not sure but check very carefully for spaces in the field name
maybe a return?

Simon

[CodeTRUCKER]

Thanks for letting me keep the thread.

No spaces or returns.

Ok, let me ask you to code the following...

1. You have an app named "Simon's App."
2. When it opens you want a textbox to contain, "123."

How would *you* code it?

[Simon]

Hi Calvin,
The simple answer is just to save the app with 123 in the field.
But that is not what you are asking I think.

Start with a new stack put 1 button and 1 field on it (really new stack, no cheating)
in the button script put

Code: Select all

on mouseUp
put "123" into fld 1
end mouseUp

note fld is short for field
fld 1 is the lowest "layered" field

That should help you find out what is wrong with GroundSpeedBox naming

more to what you want, in the card script

Code: Select all

on openCard
put "123" into fld 1
end openCard
