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>

I have used object tag in Htm file and have provided the classid and codebase to my code. My method Data() is calling successfully but the view of my ActiveX control is not visible. I don't want to use Caspol.exe to fix my query

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Data;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Runtime.InteropServices;

namespace ActiveXControl
{
    [ComVisible(true)]
    [ClassInterface(ClassInterfaceType.None)]
    [Guid("2F76566A-964F-4547-BD48-EE498AE1A7A2")]
    [ProgId("ActiveXControl.ControlClass")]
    [ComDefaultInterface(typeof(Intermediate))]
    public partial class ControlClass : UserControl, Intermediate, IObjectSafety
    {
        public ControlClass()
        {
            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;
        }
    }
}

This code is written in my ActiveX class where it can be clearly seen that constructor is calling the method to Initialize form object.
