Question

I have a program which I want to store information in a string. I have been using the Properties.Setting.Default.STRINGname to store the information, which works fine on my PC, and I can see the saved strings (when I go to the settings in the application). But when I take the application to a new PC it losses the strings. Is there a way to be able to edit this information and save it in the app? So basically I need to be able to convert the user setting to application setting, but after the runtime.

var settings = Properties.Settings.Default;
        settings.H1 = textbox1.text;
        settings.H2 = textbox2.text;

        settings.Save();

MSDN explicit says something about this:

Settings that are application-scoped are read-only, and can only be changed at design time or by altering the .config file in between application sessions. Settings that are user-scoped, however, can be written at run time just as you would change any property value. The new value persists for the duration of the application session. You can persist the changes to the settings between application sessions by calling the Save method.

For this, Application setting will never work for you. However, if you are using a User scoped settings it does work, but soon you change the application from one computer to another (as you say you want to) you will loose the settings as that’s another machine (another user-scope)…

There are way to continue to have the same settings, you can do, at least 2 things:

• use a .config file to save the settings (it’s an XML file)
• use a service to host the settings and you can read if user has internet access

What you can’t do is

• using only one executable file, save the settings from computer to computer.
