I have a webbrowser control that navigates to sharepoint port.
How can i send credentials to webbrowser control, so i can navigate to the site with custom credentials?
It depends on the authentication method used by the server. For form authentication you just need to simulate a form post. But most likely the site is using integrated Windows authentication and you need to implement IAuthenticate(Ex) Or impersonate via LogonUser.
