Automatically Populate Username and Password in Ie Windows Authentication Input Box

Visual Studio374
We are trying to automate the process of getting shipping rate quotes

from various shipping company web sites. Some of the web sites

present an input dialog box asking for a username and password when

you click login. (For example: when I navigate to

www.myyellow.com there is a logon link. When I click on the

link a separate authentication input box entitled "Connect to

www.myyellow.com" pops up and has a username field and a password

field. www.roadway.com does the same thing)



Is there anyway to programmatically populate the windows

authentication input box username and password field automatically

without using SendKeys? If so, does anybody have some example code

for doing this?



Thanks in advance,

Shawn
