Access webpage with credentials using winforms in C#.Net

Question

Hi all,

Thanx in adv,

i have a windows application which gets the username and password for a webpage.

On clicking a button in the windows application after filling the username and password, it has to open that particular webpage using the credentials.

Kindly tell some method to acheive.

I followed

System.Diagnostics.process.start("Weblink", username, password, domain);

it is giving Win32 exception stating "Parameter is Incorrect".

I think it is problem with the domain name what i have given.

what should be the domain name in Webpage.

Regards,

Ansar
