In order to run the BrowserTextControl component in Internet Explorer, the .NET Framework security mechanism
Code Access Security (CAS) must be adjusted. Our documentation describes how to adjust these settings manually:
Adjusting the Client-Side Settings Manually
So we need another confident way to adjust these settings.
The following screenshot shows a Windows Forms application that is able to adjust the settings with elevated user rights. This application can be published using
ClickOnce, so that your users can start this process directly on your website.
All you need to do is to download this project and to change the URLs in the
newSettings.MembershipUrl = @"http://www.textcontrol.com/*";
newSettings.RedirectUrl = @"http://www.textcontrol.com";
Then you might want to sign it using your certificate in order to publish the application using ClickOnce.
The password for the temporary certificate is: txtextcontrol
In the ASPX page that contains the BrowserTextControl OBJECT tag, you can add an HTML link that refers to the published wizard folder:
<a href="SecuritySettings/tx_security_wizard.application">Start security wizard</a>
When the wizard is downloaded and started, the user just need to click on the
Run button and the security settings are adjusted automatically. After that, all Internet Explorer instances are closed and reopened again automatically to apply these changes.
