4. Set the names, types, and default values to whatever you like. DO NOT change the scope to “Application” if you plan on being able to edit the settings from the code.

5. Getting and Setting the property:

    Setting:  Properties.Settings.Default.[Name of Property] = [String, Int, etc. (As long as it is the same type as the property)];
