Where are My.Settings saved in VB 2010 .NET?

Question

Are My.Settings values saved in the program itself or do they get stored in the registry? So, for example, if I set a My.Settings value with a program, then I copy the program itself to another PC - is the My.Settings value still set?

Answer 1

It depends upon the scope you have selected. There are two scope settings - Application and User scope.

From MSDN article:

Application-scoped settings are read-only and are shared between all users of that application. These settings are stored in the app.config file in the section. At run time, the app.config file will be in your bin folder and will be named with your application's name (MySettingsDemo.exe.config).

User-scope settings are specific for each user. They can be read and set safely by the application code at run time. These settings are stored in a user.config file. To be technically accurate, there are two user.configs per user per application—one for non-roaming and one for roaming. Although the Visual Basic 2005 documentation states that the user.config file will be named according to the user's name (joe.config), this is not the case. The user.config file is created in the:

<c:\Documents and Settings>\<username>\[LocalSettings\]ApplicationData\<companyname>\<appdomainname>_<eid>_<hash>\<verison>.

Answer 2

Dim config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.PerUserRoamingAndLocal)
MessageBox.Show(config.FilePath)
