Preserving My.Settings between product versions

Hi all,

Apologies if this is a FAQ - I've searched all the groups I can think of,
though.

I've written a VB.NET application and an associated Installer project in
Visual Studio 2005. My.Settings works just great, but the problem is that
when I produce a new version of the application, the My.Settings
user-related settings are lost - presumably because they're saved in the
version-specific application data directory and so when a new version number
arrives, the settings file reverts to the default (blank) values.

Is there a straightforward way of making the system "remember" the settings
when the version number increases?

Many thanks in anticipation,

David C
 
Hi David,

To reflect a most recent installation of the application, we can use
My.Settings.Upgrade method. It will search for the user.config file in the
most recent version of user profile, and copy it the current version
folder. Also, you have to make sure this method is only called once in
your app's first run.

For more information, please check the following link:

tingsbase.upgrade.aspx

If anything is unclear, please feel free to let me know.

Hi Kevin,

Sorry, been away. Yes, that worked a treat thanks. I've just added a boolean
to My.Settings, with default value False, and then in the .Load handler for
the application, chucked in:

IF NOT My.Settings.lUpgraded
My.Settings.Upgrade()
My.Settings.lUpgraded = 1
END IF

Works like a charm - many thanks.
