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.

Accepted Answer

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
