.net - Programmatically add trusted sites to Internet Explorer

Question

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.

Answer 1

Have a look at this

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

HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionInternet SettingsoneMapDomainsDOMAINNAME

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