I basically am working on a application where a person signs in by providing authentication details in a visual basic application. Now when he signs in through this application, Internet Explorer opens.I have made this application System Model. But i dont want the user to access the local drives through Internet Explorer.Which i am not able to control currently. I know i can stop access to local drives by making changes in Registry i.e. HKEY_CURRENT_USER\Software\Policies\Microsoft\Internet Explorer\Restrictions. Please advice me how do i make changes in registry through visual basic.I have to changes the values when the application starts and again when the application ends.
