B4J Question Best way to save Textarea data to a file

I've been searching in the forum and outside of the forum, and I can't find an example of how to save Textarea data to a text file?

Can I write the entire Textarea in one line or do I need to use a for next loop?

Thank you for any help...

Can I write the entire Textarea in one line

Yes ... no need to Loop.

You could use the following ...

File.WriteString(File.DirData("MyApp"), "Text.txt", TextArea1.Text)   'write text to file

TextArea1.Text = File.ReadString(File.DirData("MyApp"), "Text.txt")   'read text from file

You could also use KeyValueStore (Internal lib) ... It is very simple to use and can store much more in single database (App settings, maps, lists etc)

Private KVS As KeyValueStore  'Process_Global

KVS.Initialize(File.DirData("MyApp"), "datastore.db")  'App Start


KVS.Put("TextArea1 Contents", TextArea1.Text)        'write data

'If KVS.ContainsKey("TextArea1 Contents") Then
    TextArea1.Text = KVS.Get("TextArea1 Contents")   'get the data ...  (your choice to check that key exists first.)
'End If
