Is there a way to implement custom InternetSecurityManager in .Net.
Problem Description:-
We currently have WebBrowser control implemented in C++. We do a custom implentation of InternetSecurityManager in our code. Reason being we have our own ActiveXControls embedded in our HTML pages. IE by default shows security Manager "An ActiveX Control might be unsafe for other parts of this page....................". We handle this messagebox ourselves instead of letting user do it everytime they navigate through the app.
Now we want to host webbrowser control in .net using managed c++ extensions or c#.
How can I get the same functionality in .net or is there a better way to allow ActiveX controls to run without showing the security warnings. Our App only suppresses security warnings for our own ActiveX controls and we don't alter IE's security settings.
Thanks for your help.
