Automatic login 2

[JontyMC]

I've created a login control for a windows form app. I want to add a checkbox so users can save their login details and automatically login. Question is this - how and where do I save the login details?

You can save them just about anywhere you want I guess.

I do most of my saving of data in XML. Something simple like a username and password could be a simple txt file.

I save settings that are application specific to System.Windows.Forms.CommonAppDataPath

And settings that are user specific to System.Windows.Forms.UserAppDataPath

You could also save them to the registry (Not recommended by MS) or to a database, if your application uses one.

And if you want security, you could scramble/encrypt the login and password before saving them to disk

What are these:

System.Windows.Forms.CommonAppDataPath?
System.Windows.Forms.UserAppDataPath?

those are strings, which are directory paths.

UserAppDataPath usually equates to something like:

C:\Documents And Settings\UserName\Application Data\Company Name\Application Name\1.0.0.0

and CommonAppDataPath equates to something like:

C:\Documents And Settings\All Users\Application Data\Company Name\Application Name\1.0.0.0

When I save a users settings file, I use this code:

using System.Windows.Forms;

mySettings.Save(UserAppDataPath + "\\Settings.xml");

Sorry I made a mistake, they should be

System.Windows.Forms.Application.CommonAppDataPath, and
System.Windows.Forms.Application.UserAppDataPath

Take a look at the AppSettings member of the ConfigurationSettings class. It gives you access to a XML file which can hold the entire configuration for your application ( sort of an .INI file, if you want). It is fully customizable, you can write anything you want there. You can store encrypted user/pasword/auto_logon options there.
