C#

Properties.Settings.Default.ProgramTitle = head;

If these are user settings then they are not writing in your application config file but elsewhere. If you were to restart the application and fetch the values again you should see the new values. Check that these setting are indeed user settings because application settings cannot be changed at runtime.

How do you know that they are not saved ?

Vartan Khachatourian 8-Aug-12 6:27am

Because when I'm checking them they seem not changed and when I restart the application, it loads the previouse values.

You have your setting in a class library, it should be part of your application.
If your settings are supposed to be changed from within your library then create an interface on top of the settings where all properties that are needed in the library are specified, then create a partial class for the settings class and add the interface. From then on you can pass the interface towards the library and start using the interface. The interface should be part of the library too.

The code that changes the values and saves (in my question) is in the class library. It's already trying to change the setting from the class library.

Philip Stuyck 8-Aug-12 7:57am

application settings cannot belong to a class library. That is the problem.

Ok Philip I'm trying this. I'll tell you the result. by now
