[Gambas-user] Corruption of application.conf with Raspberry Pi

[Bruce Steers]

sorry i read your question on my phone at work and misread it.

various things can cause default settings load.
difference in exe filename/launching from a link, etc. By default
Settings.class uses the application name if you create a symlink then the
application gets a different name and so does the settings file , to fix
this use an explicit name.
Ie.  make a public variable
*Public mySettings As Settings*

then use...
*mySettings = New Settings(Settings.DefaultDir &/
"myExplicitSettingsFile.conf")*
then search and replace* Settings[ *for *mySettings[ *in your source.
then you are sure to use *myExplicitSettingsFile.conf *every time.

alternatively you could simply import the Settings.class and modify it to
work exactly how you want it to.
I wrote a quick "how to" on importing the gb.settings component here...
https://forum.gambas.one/viewtopic.php?f=6&t=1029
If you do not know how to import gb.settings then that will let you know
how.

you could then add a static *DoNotSave* variable to your Settings.class
file and stop it saving in* Public sub _free()*

Hope that helps
