so I've started using the Webbrowser control, and I've got it doing most of what I want (a button takes them straight to the correct page on the correct site, it's filling in text boxes, will fill out more once I get to that step).

However when I go to the particular secure site my users are supposed to login to, it brings up what I assume is a windows domain login prompt with a check box to save the userid/password.

Saving the password is not allowed for this secure site, and when I use system.webclient to get the first page so I can use my own windows for getting the login info, it doesn't carry over the authentication info to the webbrowser if I let it go back to using the web browser's default navigation methods, nor does it load the images or the page properly.

I was thinking I needed to set the webbrowser's credentials, but I can't find anything exposed to make changes to or override if I try to inherit.

i'm behind a webproxy, and the site itself requires login. I've figured out in code how to pull back secure pages that require you to be logged in, but when I pass that html up to the webbrowser it doesn't know how to access or load the images or other things that the html instructs it to do.
