I have declared a CONNECTION key in app.config. Which I used throught out my application.
Want to have a SETTINGS page (GUI) in my application, which asks for Database name, Server, user id and password.
How can we change values in app.config file, updating the CONNECTION key with what user has entered.
Hope you understand what im looking for.
In a nutshell, you have declared a KEY in your app.config and you want to change it thru an interface.
