Very nice code snippet.

I did something much like it -- thank you for the inspiration.

* I combined the Load & Save loops into a single loop (LoadSaveSettings), with a direction value, so that new controls only need be added to one location.

* I modifed the storage code for TextBoxes to encrypt (DPAPI) values in password text boxes (I'm testing on the SystemPasswordChar right now).

* I used a Settings class, instead of RegKey, so I can abstract storing a string/value pair -- my version does that via a Settings class, which talks to a SettingsStorageProvider which it gets from a factory of such -- so that the decision whether to store via XML or registry can be made at a much higher level.

* I return a FormSettings object from the single-line invocation (your Register) call, which can be ignored (for a one-line form solution, like yours), or caught, to adjust settings (eg, use customized entropy values for keys, or to use to save the settings at other points than the close).

* I adjusted the save code to not save if the DlgResult is set to Cancel, as I don't like saving settings when user is cancelling a dialog.

There's no easy way to modify the standard message box... your best bet would be to simply create a new form that has whatever features you want (including a checkbox) and then ShowDialog on it instead of doing MessageBox.Show.

I want to save setting like your suggested in your class, but I want a checkbox on the messagebox to ask the user to save the setting. Something like never asked this question again...

How do you add this?

Nicely done! Thanks a lot for this, it is going to save me a lot of time :-P

Incedently, if anyone wants to use this code in a class, they will need to use the following namespaces...

using System;
using System.Windows.Forms;
using System.Reflection;
using System.Diagnostics;
using Microsoft.Win32;

(just in case ppl get stuck)
