Answer 1

You can override the web-browser's control method CreateWebBrowserSiteBase.

protected override WebBrowserSiteBase CreateWebBrowserSiteBase()
{
    return new ExtendedWebBrowserSite(this);
} 

and implement ExtendedWebBrowserSite like this:

class ExtendedWebBrowserSite : WebBrowser.WebBrowserSite,
    IDocHostShowUI,
    IfacesEnumsStructsClasses.IServiceProvider,
    IInternetSecurityManager
    ...

That can call the class IInternetSecurityManager.

One option would be to create your own dialog form (in C#) with another custom-security WebBrowser control on it. Then you can call from Javascript to C# to open the form instead of using showModalDialog.
