Making ActiveX object Browser safe

[Navitas]

Hi

I've written a dll in vb.net that I then call from an IE page using javascript - new ActiveXObject etc

However when it initialises it prompts to ask if you want to allow the use of the activeX object.

I know this is standard IE security, but how do I register my dll as Browser safe so that the prompt doesn't appear.

Many thanks
Darren

AFAIK, this is a user initiated function only, not something you can "pre-code" into your dll.

There's always a better way. The fun is trying to find it!

I don't think you can - and if you think about it, it's common sense. After all - if you can mark your own ActiveX object as safe, what is to stop a malicious programmer marking a trojan, virus, worm, etc, as safe?

Even content from Microsoft, McAfee, and Macromedia prompts you - and they're probably safer than most things available.

This is a browser setting that you'd need to change.

Hope this helps,
Dan

OK I sorted it!

This info may be useful for anyone else facing the same problem!

Note however my dll was developed to work with a local application that uses IE pages for its user interface - ie there is no web download etc.

To mark your dll as web safe, find it's class ID and search the registry for it (in HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID). Then add a new key in the Implemented Categories folder with the following value as the key name : {7DD95801-9882-11CF-9FA9-00AA006C42C4}

Your dll will the be marked as browser safe

Hope this helps
