custom properties

Hi All

I'm stuck... I've got a Mainstack plus a card. On a button that gets the directory I have the following code

Code: Select all

on mouseUp
   
   ClearVariables
      
   local tFolder
   answer folder "Please choose folder"
   put it into tFolder
   if there is no folder tFolder then exit mouseUp
   
   put tFolder into field "Folder"
   put listFiles(currentFolder()) into field "Result"
   
   set the cFolderDirectory of this stack to field "Folder"
   
   focus on fld "Result"
   
end mouseUp

When moving to another card I want to access the variable cFolderDirectory. I've been trying to do this for the last couple days and I've now come to the end of my tether... how the hell do I do this?

Hi Nigel,

well, you already used the correct syntax with "set"!
...
## Set a CP:
set the cFolderDirectory of this stack to field "Folder"
...
## Get a CP:
PUT the cFolderDirectory of this stack into tCurrentFolderDirectory
...
Hint:
Don't forget that unlike Variables, CPs are saved with the stack, so you might need to initialize/reset your CPs "on openstack", if neccessary.

Would this code snippet be on the 'other' card

## Get a CP:
PUT the cFolderDirectory of this stack into tCurrentFolderDirectory

My other card is called "MessageView"

I'm a little confused as I keep thinking in terms of OOP's rather than in LiveCode structure so i'm tripping up.

Hi Nigel,

this can be used on any card of "THIS" stack!

## Get a CP:
PUT the cFolderDirectory of this stack into tCurrentFolderDirectory
My other card is called "MessageView"

Doesn't matter, as long as the card is in "THIS" stack

If not, you can even:
...
put the cFolderDirectory of stack "Not THIS, but the other one" into tCurrentFolderDirectory
...

I'm a little confused as I keep thinking in terms of OOP's rather than in LiveCode structure so i'm tripping up.

Yep, better forget all the complicated stuff, this is Livecode!

Thx Klaus

I appreciate your assistance. You know I code in about 6 different languages, all oops oriantaed and I'm finding LiveCode the most difficult to get into, not because it's difficult but because its so simple that I over complicate things in my mind. BUT, i will crack it.

Good boy!
