Company Firewall With System.Windows.Forms.WebBrowser
Nov 22, 2010VB2005. In my application I am required to go to a website, collect info, and then display both the webpage and the info collected. For this I am using the System.Windows.Forms.WebBrowser component and have it working faily well. The only thing now is that in order to get to external websites the company requires us to login to the firewall proxy server. For example when I visit [URL] a login box pops-up for our firewall server [URL] and I sign in with ID 9999 and password "pass". I am trying to programatically do this with the WebBrowser by using the credentails but have not found any relevant examples. Is this possible with the System.Windows.Forms.WebBrowser component?
