How can an application change settings in the web.config file? I need to
allow users to configure SMTP email settings with functionality similar to
that provided developers by the ASP.NET Web Site Administration Tool. I
believe that I can get the settings using ConfigurationMa nager.GetSectio n,
but how can I save changes? If I do find a way to save changes, how can I
get IIS to read the file again so that the changes become immediately
available to the web site?
Thanks,

Hi Keith,
You're in luck because ASP.NET 2.0's Web Admin application does all this and
the source code is included. Take a look here:
C:\WINDOWS\Micr osoft.NET\Frame work\v2.0.50727 \ASP.NETWebAdmi nFiles\AppConfi g
Also, check out the Save method here: http://msdn2.microsoft.com/en-us/lib...ve(VS.80).aspx

// check if session expired

String.IsNullOr Empty((string)S ession[APP_PHYSICAL_PA TH])) {
Server.Transfer ("~/home2.aspx");
}
config.Save(Con figurationSaveM ode.Minimal);

As for the second question, IIS resets the application as soon as there's a
change to the web.config.

There's lots of ways, such as simply reading and writing your changes via
file classes, to reading the file into a XMLDom object, making changes, and
saving it again.
However, you should be VERY careful about this, since changing the
web.config file will cause any currently running application (including the
one you're making the changes in) to reset, losing things like session
variables, authentication, the currently state, etc.. Basically, you will
dump the user out of the website entirely, as well as every other user
currently on the site.
If that's not what you want, then you might need to look at other ways of
storing your data that needs changing.
If you want your changes to be immediately available after being written
without having the web application restart on you, then you'll need to wite
them either to an xml file or preferably to a database.
You can have a method in your configuration class's code that automatically
re-reads the data from the database (or file) whenever a change is made.
IIS doesn't read web.config files - the ASP.NET runtime does.

ConfigObj is a module to enable you to much more *simply* access

This is version 3, which is a big overhaul. It extends ConfigObj to
reading config files with sections and various other simplifications.
