how to fill the user/pass fields in the popUp window of the HTACCESS from c#

Question

i want 2 automate the proccess of login into site usin Htaccess.. and instead of enetering the user/pass in the annoying popup window i wanna login directly into the site.. .like http://user:[email protected]... but this is not available in IE.. so i wodered if there any way from c# (maybe using axWebBrowser, or something else) 2 fill the 2 fileds of user/pass automaticly into the pop up window, or skip it completly cause i open the ie from c# like that: System.Diagnostics.Process.Start("iexplore.exe",site) and i have the user/pass already stored in xml file... so i dont wanna retype it again int the pop up window of HTaccess thx ahead!
