.net – Programmatically add trusted sites to Internet Explorer

.netautomationinternet-explorertrusted-siteswatin

I'm doing an IE automation project using WatiN.

When a file to be downloaded is clicked, I get the following in the Internet Explorer Information bar:

To help protect your security,
Internet Explorer has blocked this
site from downloading files to you
computer.

In order to download the report, I can manually add the site to Internet Explorer's list of trusted sites, but I would prefer to check programmatically in .NET to see if the site is trusted and add it to the list if it is not.

FYI, I'm currently using IE7.

Have a look at this

Basically it looks as if all you have to do is create registry key in

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains\DOMAINNAME

then a REG_DWORD value named "http" with value==2

I wouldn't do it. Use virtual PCs instead. It might take a little setup, but you'll thank yourself in the long run. In my experience, you can't really get them cleanly installed side by side and unless they are standalone installs you can't really verify that it is 100% true-to-browser rendering.

Update: Looks like one of the better ways to accomplish this (if running Windows 7) is using Windows XP mode to set up multiple virtual machines: Testing Multiple Versions of IE on one PC at the IEBlog.

Update 2: (11/2014) There are new solutions since this was last updated. Microsoft now provides VMs for any environment to test multiple versions of IE: Modern.IE

Javascript – Detecting Current Internet Explorer Security Zone

In IE7, you could use the following JavaScript to get some idea of whether your site is trusted or not:

window.status = "test";
if (window.status == "test")
  alert("Trusted, or local intranet");
else
  alert("Not trusted, or internet");

This is based on the fact that in IE7 and onwards, scripts can no longer set the status bar text through the window.status method in the Internet and Restricted Zones. See the Release Notes for Internet Explorer 7
