An activex control on this page might be unsafe

activex

I created a com component in C#, which I registered by using Regasm. I am able now to use this in IE by using ActiveXObject(…). However this only works when I change my IE security settings and allow to run unsigned activex controls, in which case I get the message:

An ActiveX control on this page might be unsafe to interact with other parts of the page. Do you want to allow this interaction?

I always want IE to allow this interaction without the prompt. Does anybody know how this can be done?

Thanks

Your ActiveX control must implement the IObjectSafety interface in order for IE to stop showing the "unsafe?" prompt. I did this several years ago for a VB6 ActiveX control. In the 5th step of This page is shown how to do it in .Net.

By pure hackery, I discovered that setting the following registry value does it:

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\0]
"1201"=dword:00000000

But I'm still wondering whether there's any supported way of doing this.

You can't. Your users can, by giving your page trusted access to their computer (e.g., by adding the URL to the "Trusted Sites" zone).
