Hi, I've jumped projects again (as I tend to do) and for this particular project, I'm using Custom Properties to save text data. I've based my script on a good stack I found in RevOnline. That all works fine except it loads one line from each field.

So I've been thrashing about trying to come up with a way to retrieve/save multiple lines from each field. For retrieving, my thinking is that when the user selects a particular line in a list box, then if I could find that particular string in the field with the data saved as the custom property, then the next amount of items could easily be put into the relevant fields.

So here's my clumsy code (in the list field):

Code: Select all

on mouseUp pMouseBtnNo
       set itemdel to "#"
put the selectedText of me into Thisone
find Thisone in field "Main"
  put the number of item Thisone in field "Main" into tCount
  put item tCount into field "A"
put item tCount + 1 into field "B"
put item tCount + 2 into field "C"
end mouseUp

The basic problem with this is I don't know how to find the item number within the field "Main" of the string taken from field "Choice". (i.e my code "put the number of item Thisone in field "Main" into tCount" doesn't work...) Could anyone advise me please

hi gyroscope,
look for itemOffset(itemToFind,stringToSearch[,itemsToSkip])
I dont really understand how you get the selection etc
this works, kind of, in a button

Code: Select all

on mouseUp
    set itemdel to "#" 
    put the selectedtext of field "choice" into Thisone 
    put itemoffset(Thisone,field "main") into tCount
    put item tCount of field "main" into field "A" 
    put item tCount + 1 of field "main" into field "B" 
    put item tCount + 2 of field "main" into field "C" 
end mouseUp

watch out for multiple occurences of the item, without the skip you always find the first one
maybe you would like to post a sample of your data and stack in revonline
cheers

If your list is showing all the items in the same sequence as your complete data container field, it can be as simple as

Code: Select all

on selectionChanged
  put the hilitedLine of me into ThisLine
  put line ThisLine of field "Main" into ThisLineData
  -- now extract items out of of ThisLineData to populate your fields
  set the itemDelimiter to "#"
  put item 1 of ThisLineData into field 1
end selectionChanged

However, if the lines in your list field are in a different sequence, you're best off using the lineOffset function to find the exact line on which your data is.

Code: Select all

on selectionChanged
  put line (the hilitedLine of me) of me into ThisLine
  put line lineOffset(ThisLine & "#", field "Main") of field "Main" into ThisLineData
  -- now extract items out of of ThisLineData to populate your fields
  set the itemDelimiter to "#"
  put item 1 of ThisLineData into field 1
end selectionChanged
