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

Using powershell it is quite easy.

#Setting IExplorer settings
Write-Verbose "Now configuring IE"
#Add http://website.com as a trusted Site/Domain
#Navigate to the domains folder in the registry
set-location "HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings"
set-location ZoneMap\Domains

#Create a new folder with the website name
new-item website/ -Force
set-location website/
new-itemproperty . -Name * -Value 2 -Type DWORD -Force
new-itemproperty . -Name http -Value 2 -Type DWORD -Force
new-itemproperty . -Name https -Value 2 -Type DWORD -Force

Answer 2

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
