How do you change Button Labels with script?


The script below does not work, Why?

set the label of Button1 to "David"

Thanks,

David

Sorry to be such a bother!

After looking at some more examples and beating my head against the wall, I saw my error.

The code should have been:

set the label of button Button1 to "David"

Good work.

Do you see that the first script was syntactically correct? But that it changed the label of a button you were not interested in? Did you see that label change, and did that give you a clue as to what you really needed?

I didn't see the error immediately either -- which is why I try not to name objects starting with their type. I.e., I avoid names like "button1" because when I read it I don't notice any problem. If I name it something descriptive like "Next page" then the missing object specifier is easy to spot. It's kind of too bad the IDE does that sort of naming by default. I always change them.

Sometimes I do want the object type in the name though. In those cases I put it at the end: "editingFld" or "firstnameLbl" to avoid trip-ups.

Well, now that I read it correctly...

So you got an error. I thought is was "button 1", when in fact it was "button1". You did not have an object identifier, only a name.

You could do something to "button 1" (the first button). But you need to specify what object "button1" is. Could be a field.

Craig,

Thanks for your following of my posts and your understanding .

The "Button1" is not a good name in a real program,
I am just writing a test program to explore what LiveCode can do in my current project to develop an mobile app for my Sunday school class.
