我正在使用ActiveX控件并通过msi安装它。 使用ActiveX用户控件类编写的方法正在触发，但UI不可见

Question

<object name="Form" id='Form' classid='2F76566A-964F-4547-BD48-EE498AE1A7A2' 
       codebase='ActiveXControl.cab#version=1,0,0,0'
       width="500px" height="500px" style="background-color:Blue">
</object>

<script type="text/javascript" language="javascript">
    var x = new ActiveXObject("ActiveXControl.ControlClass");
    x.UserTxt = "Aashish";
    x.password = "Rockstar";
    x.getmethod();
    alert(x.Data());
</script>

我在Htm文件中使用了对象标记，并为我的代码提供了classid和代码库。 我的方法Data（）成功调用，但是ActiveX控件的视图不可见。 我不想使用Caspol.exe修复我的查询

    public partial class ControlClass : UserControl, Intermediate, IObjectSafety

            InitializeComponent();
        }
        public string UserTxt { get; set; }
        public string password { get; set; }

        public void getmethod()
        {
            textBox1.Text = UserTxt;
            textBox2.Text = password;
        }
        public string Data()
        {
            return textBox1.Text +" " + textBox2.Text;
        }
        public enum ObjectSafetyOptions
        {
            INTERFACESAFE_FOR_UNTRUSTED_CALLER = 0x00000001,
            INTERFACESAFE_FOR_UNTRUSTED_DATA = 0x00000002,
            INTERFACE_USES_DISPEX = 0x00000004,
            INTERFACE_USES_SECURITY_MANAGER = 0x00000008
        };

        public int GetInterfaceSafetyOptions(ref Guid riid, out int pdwSupportedOptions, out int pdwEnabledOptions)
        {
            ObjectSafetyOptions m_options = ObjectSafetyOptions.INTERFACESAFE_FOR_UNTRUSTED_CALLER | ObjectSafetyOptions.INTERFACESAFE_FOR_UNTRUSTED_DATA;
            pdwSupportedOptions = (int)m_options;
            pdwEnabledOptions = (int)m_options;
            return 0;
        }

        public int SetInterfaceSafetyOptions(ref Guid riid, int dwOptionSetMask, int dwEnabledOptions)
        {
            return 0;
        }
    }
}

这段代码是用我的ActiveX类编写的，可以清楚地看到构造函数正在调用方法来初始化表单对象。
