arrayEncode

[drOrganized]

I would like to store the content of a data grid in a file. I tried the following without success:

put the dgData of group "test" into pArrayData
open file "Test" for binary write
write arrayEncode(pArrayData) to file "test"
close file "Test"

Nothing is written to the file.

I tried also

open file "Test" for binary read
read from file "Test" until empty
put arrayDecode(it) into pArrayData
close file "Test"
set the dgData of group "test" to pArrayData

I suppose I could convert the array to a variable and then save the variable and vice versa, but I got the impression from the User Dictionary that the code above would work.

Any help much appreciated.

drOrganized,
I did not get your script to work either. I don't know why. But

Code: Select all

   put the dgData of group "DataGrid 1" into pArrayData
   put arrayEncode(pArrayData) into pArrayData
   put specialfolderpath ("desktop") & "/" into aPath
   put "arrayExportTest" after aPath
   put pArrayData into URL ("binfile:" & aPath)

works for me.
I reimported the data into the datagrid and with arrayDecode it works.

The difference between the working an non-working scripts suggests the issue is in the way the data is read.

I wonder if changing "read until empty" to "read until EOF" would work.

drOrganized,
here is the script that reads the data and populates the datagrid

Code: Select all

on mouseUp
    put specialfolderpath ("desktop") & "/" into aPath
    put "arrayExportTest" after aPath
    breakpoint
   put url ("binfile:"& aPath) into pArrayData
   put arrayDecode(pArrayData) into pArrayData
   set the dgData of group "DataGrid 1" to pArrayData
end mouseUp

this works for me
