[Gambas-user] Writing to a file on disk

[Matti]

If you want to store just a few informations from your project, there is also
the very simple way via the gb.settings component.

You have to choose this component in the project properties first.

Then (this is Gambas3, look in the docs if you use Gambas2):
Write:
Settings["MyText/1"] = result.Text
Read:
result.Text = Settings["MyText/1"]

The automagically generated file MyProject.conf is stored in ~/.config/gambas(3).

So, if you don't have to save "real" files, you don't have to care about
opening, reading, writing and closing files at all.

Regards
Matti
