签署用作ActiveX控件的.NET DLL

Question

我有一个COM可见的.NET DLL文件,在Internet Explorer中显示的网页中用作ActiveX控件.

当通过网页上的JavaScript代码调用时,控件本身可以正常工作(虽然有一些注意事项).

问题在于签署DLL并使其可靠地访问.我(据我所知)在Visual Studio中签署项目.在项目的"签名"属性中,我创建了一个.pfx文件,并使用它来签署DLL.

在Internet Explorer中,无论我做什么,我都无法让Internet Explorer在没有手动进入安全设置的情况下加载ActiveX控件并更改"下载未签名的ActiveX控件"和"初始化和脚本ActiveX控件不标记为脚本安全" '启用/提示选项.

似乎原始问题与文件的签名无关,而是在IObjectSafety的实现中.为了允许IE加载,我需要正确实现该接口,并且它工作正常(即使没有有效的签名).

简单的例子:

[ComImport()]
[Guid("CB5BDC81-93C1-11CF-8F20-00805F2CD064")]
[InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
interface IObjectSafety
{
    [PreserveSig()]
    int GetInterfaceSafetyOptions(ref Guid riid, out int pdwSupportedOptions, out int pdwEnabledOptions);

    [PreserveSig()]
    int SetInterfaceSafetyOptions(ref Guid riid, int dwOptionSetMask, int dwEnabledOptions);
}

班级本身:

[ProgId("Testing.Test")]
[ClassInterface(ClassInterfaceType.AutoDispatch)]
[ComVisible(true)]
public sealed class Test : IObjectSafety
{
    #region Saftey Interface
    private const int INTERFACESAFE_FOR_UNTRUSTED_CALLER = 0x00000001;
    private const int INTERFACESAFE_FOR_UNTRUSTED_DATA = 0x00000002;
    private const int S_OK = 0;

    [ComVisible(true)]
    public int GetInterfaceSafetyOptions(ref Guid riid, out int pdwSupportedOptions, out int pdwEnabledOptions)
    {
        pdwSupportedOptions = INTERFACESAFE_FOR_UNTRUSTED_CALLER | INTERFACESAFE_FOR_UNTRUSTED_DATA;
        pdwEnabledOptions = INTERFACESAFE_FOR_UNTRUSTED_CALLER | INTERFACESAFE_FOR_UNTRUSTED_DATA;
        return S_OK;
    }

    [ComVisible(true)]
    public int SetInterfaceSafetyOptions(ref Guid riid, int dwOptionSetMask, int dwEnabledOptions)
    {
        return S_OK;
    }
    #endregion

    [ComVisible(true)]
    public string TestString
    {
        get
        {
            return 'A Test';
        }
    }
}
