Hallo Xojo community,
I’m a new member. I beginn to learn with the ToDo listbox tutorial. At the end I added a “SAVE” button but don’t have any knowledge to write the appropriate code to save the ToDo list, for example as csv-file, in a manner that I can later load the file, to add further tasks and save it one more time.
please take a look at these topics in the Xojo-Documentation(->Help ->Language Reference or F1 within Xojo):
Everything you need is described there with examplecode (for listbox data there is a example at textinputstream) to start with.
Desktop, Web, List, iOS ?
Compare the code below * to the TextInputStream example I took it from:
Dim t As TextOutputStream
Dim f As FolderItem
f = GetSaveFolderItem("", "Save_As_Example.csv")
If f <> Nil Then
t = TextOutputStream.Create(f)
Nota: the code above do not makes reliable backup file (in one test, it store everything from a certain Row until the end of the Listbox into only one Row instead of 20/280 Rows.
But this is an example.
LB is the reference of the ListBox.
The Column delimiter is the default value: a Tab.
If you want another delimiter, change it before saving it to disk.Same apply of you want to put all Cells contents between quotes.
And so on.
Load LibreOffice, create a Calc File, populate it and try to export it to csv to know how “the industry” proposes.
Now you have an example to works from (simplistic).
Did I told you that examples of csv files and question about csv exists in this forum ?
BTW: I took the example from the API 1 LR. Changes may happens with API 2.
Hallo Rolf, Danke.
Bonjour Emily, Merci.
I will try my best and post a feedback.
Pardon Emile, i wrote wrong your Name.
