Application settings

Hi

For my db app, I need to save the location of the db (really a windows path)
which normally only needs to be set at the first app start (I can check if
the setting is missing and ask user for a value). Occasionally (once in a
blue moon) I may need to change this setting in case db is moved to a
different server etc.

My question is what sort of mechanism can/should I use to store this
setting?

Thanks

Regards

A simple way to do that is using My.Settings ...

Go to Project > Properties ... > Settings and add a setting name (i.e. =

db_path and set a Type for it)

Then, in your application, u can read it and write it using:

Read: Msgbox ( My.Settings.db_path.ToString )

Write: My.Settings.db_path =3D "anything"

ACK, but note that application-scoped settings cannot be changed using
'My.Settings'. Typically the user running the application doesn't have
rights to manipulate the contents of the program files folder.

If you have users without admin rights you're down to the registry or an
XML/ini file somewhere in the user's 'My Documents' folder.
