I have a problem. I want write the contents of every data cell of every data row to a file and then I want to load this file again to my tableview (with 2 data cells). How can I do this?
Many thanks for your help!

Here is my code. I can write the contents of the table to a file, but when I load the file every cell and every row is the same!
property tableData : {{the_name:"Bart Simpson", the_city:"Springfield", the_zip:"19542", the_age:12}, {the_name:"Ally McBeal", the_city:"Boston", the_zip:"91544", the_age:28}}
property pathName : "TableData"
on awake from nib the_object
tell the_object to center
my load_data(tableData)
show window "main"
end awake from nib
on clicked the_object
set object_name to name of the_object as string
if object_name = "write" then
my writeData()
else if object_name = "load" then
my loadData()
end if
end clicked
on should quit after last window closed the_object
return true
end should quit after last window closed
on load_data(the_data)
tell window "main"
set the_data_source to data source of table view "myTableView" of scroll view "myScrollView"
tell the_data_source
try
delete data rows
end try
try
delete data columns
end try
make new data column at end of data columns with properties {name:"the_name"}
make new data column at end of data columns with properties {name:"the_city"}
make new data column at end of data columns with properties {name:"the_zip"}
make new data column at end of data columns with properties {name:"the_age"}
end tell
append the_data_source with the_data
tell table view "myTableView" of scroll view "myScrollView" to update
end tell
end load_data
on writeData()
tell window "main"
set the_data_source to data source of table view "myTableView" of scroll view "myScrollView"
tell the_data_source
set informationFromEveryCell to contents of every data cell of every data row of the_data_source
set theFile to open for access (pathName as POSIX file) with write permission
set toSave to {tabellData:informationFromEveryCell}
write toSave to theFile
close access theFile
end tell
end tell
end writeData
on loadData()
set theFile to open for access (pathName as POSIX file)
set theData to read theFile
close access theFile
tell window "main"
set the_data_source to data source of table view "myTableView" of scroll view "myScrollView"
tell the_data_source
set contents of every data cell of every data row of the_data_source to theData
end tell
end tell
end loadData
I don’t understand what you’re trying to do. Perhaps that is why no one has answered. Your script seems to indicate you have 4 columns, but you mention “two data cells.”
Can you describe more fully what you are trying to do, and then what is happening with the code you have now?
I have a app with a tableview with 4 columns! Sorry…
I want to save all contents of the tableview to a file and I would like to be able to load the file to my tableview again.
But now, when i load the .txt-file with the contents from tableview to my tableview, there are in every data cell the complete contents from the file…
When i load the file to my tableview i want to have the contents from the column 1 in column 1 an from column 2 in column 2 and so on…
but how can i load this file again to my tableview with two columns (the_name & the_city)
Now can anybody help me? I hope so…
Many thanks for your help!
That´s my script:
property tableData : {{the_name:"Bart Simpson", the_city:"Springfield"}, {the_name:"Bart Simpson", the_city:"Springfield"}, {the_name:"Bart Simpson", the_city:"Springfield"}}
property tableData2 : {{the_name:"Judy Sorn", the_city:"NYC"}}
property the_arrow : missing value
property pathName : "TableData"
on awake from nib the_object
tell the_object to center
my load_data(tableData)
show window "main"
end awake from nib
on clicked the_object
set object_name to name of the_object as string
if object_name = "quit" then
quit
else if object_name = "data1" then
my load_data(tableData)
else if object_name = "load" then
my get_prefs()
else if object_name = "data2" then
my load_data(tableData2)
else if object_name = "save" then
my save_data()
end if
end clicked
on should quit after last window closed the_object
return true
end should quit after last window closed
on load_data(the_data)
tell window "main"
set the_data_source to data source of table view "myTableView" of scroll view "myScrollView"
tell the_data_source
try

end try
make new data column at end of data columns with properties {name:"the_name"}
make new data column at end of data columns with properties {name:"the_city"}
end tell
append the_data_source with the_data
tell table view "myTableView" of scroll view "myScrollView" to update
end tell
end load_data
on save_data()
set p to open for access (pathName as POSIX file) with write permission
set the_data_source to data source of table view "myTableView" of scroll view "myScrollView" of window "main"
set eof p to 0
tell the_data_source
set every_data_row to every data row of the_data_source
repeat with i in every_data_row
set the_name to contents of data cell 1 of i
set the_city to contents of data cell 2 of i
my write_line(("the_name:") & (the_name) & " " & ("the_city:") & (the_city), p)
end repeat
end tell
--set informationFromEveryCell to contents of every data cell of every data row of the_data_source
close access p
end save_data
on write_line(a, b)
write a to b
write (ASCII character 10) to b
end write_line
