Save Settings in VB.Net or C#

I recommend using Application Settings Property Binding.

There are many options as mrunion mentioned in his good answer, but I think the most simple way in Windows Forms Application is using Application Settings Property Binding. To do so using designer:

1. Select your CheckBox in design surface
2. In properties window, at top, expand (ApplicationSettings), open dropdown for Checked property and select (New...) at bottom of dropdown.
3. Add your desired property with default value.

4. Save settings in somewhere like Form_Closing event:

   • C#: Properties.Settings.Default.Save();
   • VB: My.Settings.Save()

(ApplicationSettings) in property window:

Expanded from above....

To persist settings between different program runs, you will have to store that data somewhere for the user. Assuming since you mentioned VB, I will also assume Windows as your target platform. The best options are the following:

1. Use the registry to store the persistent data. There are plenty of tutorials on setting and retrieving registry variables.
2. Use a configuration/INI file for your application. Again, plenty of tutorials exist for this option.
3. Use a database. This is more advanced, but allows for the most flexibility of storing and retrieving data. I would suggest not using this method at first, and revisit it when you are ready to learn database design/querying/etc.

This should point you in the right direction.
