web service setup, getting user information on installing [v-urgent]

Hello,

VS 2005

I have created a web service and the web service as a connection string in the config file.

Only the user will know the connection string details when they first install the web service. i.e. server, user id, database etc.

I have created the setup using the msi webSetup.

However, my problem is how do i get the user information for the connection string from the user and update the web.config with the new connection details.

Need serious help with this, and code examples would be most helpful.

Thanks very much,

Steve
