在编码中不可否认调用Active会给编程带来很大便利，虽然微软不太只持.net调用Active 组件。
       本实例是一个简单Web 页面调用Active组件的例子，实现把数据传入并显示在active组件里的控件中。
　　实例代码如下：
１、建立Active组件（这里用.net　c#创建）
        （本程序中：建立类库添加组件类后托放：label 、 button  、groupBox各一个）
　　　需要注意的是在生成.dll之前一定要在类库的AssemblyInfo.cs中加入引用using System.Security;和属性[assembly : AllowPartiallyTrustedCallers()]，这是为了给控件赋予足够的权限使它能在页面上显示。

using System;
using System.ComponentModel;
using System.Collections;
using System.Diagnostics;
using System.Windows.Forms ;

namespace ActiveXDotNet
{
    /**//// <summary>
    /// AbeenControl 的摘要说明。
    /// </summary>
    public class AbeenControl : System.Windows.Forms.UserControl
    {
        private System.Windows.Forms.Label label1;
        private System.Windows.Forms.Button button1;
        private System.Windows.Forms.GroupBox groupBox1;
        /**//// <summary>
        /// 必需的设计器变量。
        /// </summary>
        private System.ComponentModel.Container components = null;

        public string LabelText
        {
            get
            {
                return this.label1.Text.ToString();
            }
            set
            {
                this.label1.Text=value;
            }
        }

        public AbeenControl(System.ComponentModel.IContainer container)
        {
            /**////
            /// Windows.Forms 类撰写设计器支持所必需的
            ///
            this.label1.Text="test";
            container.Add(this);
            InitializeComponent();

            //
            // TODO: 在 InitializeComponent 调用后添加任何构造函数代码
            //
        }

        public AbeenControl()
        {
            /**////
            /// Windows.Forms 类撰写设计器支持所必需的
            ///
            InitializeComponent();
           

            //
            // TODO: 在 InitializeComponent 调用后添加任何构造函数代码
            //
        }

        /**//// <summary>
        /// 清理所有正在使用的资源。
        /// </summary>
        protected override void Dispose( bool disposing )
        {
            if( disposing )
            {
                if(components != null)
                {
                    components.Dispose();
                }
            }
            base.Dispose( disposing );
        }

        组件设计器生成的代码#region 组件设计器生成的代码
        /**//// <summary>
        /// 设计器支持所需的方法 - 不要使用代码编辑器修改
        /// 此方法的内容。
        /// </summary>
        private void InitializeComponent()
        {
            this.label1 = new System.Windows.Forms.Label();
            this.button1 = new System.Windows.Forms.Button();
            this.groupBox1 = new System.Windows.Forms.GroupBox();
            this.groupBox1.SuspendLayout();
            this.SuspendLayout();
            //
            // label1
            //
            this.label1.Location = new System.Drawing.Point(16, 24);
            this.label1.Name = "label1";
            this.label1.Size = new System.Drawing.Size(296, 23);
            this.label1.TabIndex = 0;
            this.label1.Text = "label1";
            //
            // button1
            //
            this.button1.Location = new System.Drawing.Point(120, 56);
            this.button1.Name = "button1";
            this.button1.TabIndex = 1;
            this.button1.Text = "button1";
            this.button1.Click += new System.EventHandler(this.button1_Click);
            //
            // groupBox1
            //
            this.groupBox1.Controls.Add(this.label1);
            this.groupBox1.Controls.Add(this.button1);
            this.groupBox1.Location = new System.Drawing.Point(0, 0);
            this.groupBox1.Name = "groupBox1";
            this.groupBox1.Size = new System.Drawing.Size(320, 88);
            this.groupBox1.TabIndex = 2;
            this.groupBox1.TabStop = false;
            this.groupBox1.Text = "groupBox1";
            //
            // AbeenControl
            //
            this.Controls.Add(this.groupBox1);
            this.Name = "AbeenControl";
            this.Size = new System.Drawing.Size(328, 96);
            this.Load += new System.EventHandler(this.AbeenControl_Load);
            this.groupBox1.ResumeLayout(false);
            this.ResumeLayout(false);

        }
        #endregion

        private void button1_Click(object sender, System.EventArgs e)
        {
            this.label1.Text="点击完成！";
        }

        private void AbeenControl_Load(object sender, System.EventArgs e)
        {
       
        }
    }
}
２、web　页面调用Active组件
　　注意web页面调用时需要把Active的.dll放到web的虚拟要目录下。
