在編碼中不可否認調用active會給編程帶來很大便利，雖然微軟不太只持.net調用active 組件。
       本實例是一個簡單web 頁面調用active組件的例子，實現把數據傳入并顯示在active組件里的控件中。
　　實例代碼如下：
１、建立active組件（這里用.net　c#創建）
        （本程序中：建立類庫添加組件類后托放：label 、 button  、groupbox各一個）
　　　需要注意的是在生成.dll之前一定要在類庫的assemblyinfo.cs中加入引用using system.security;和屬性[assembly : allowpartiallytrustedcallers()]，這是為了給控件賦予足夠的權限使它能在頁面上顯示。

using system.componentmodel;
using system.collections;
using system.diagnostics;
using system.windows.forms ;

namespace activexdotnet
{
    /**//// <summary>
    /// abeencontrol 的摘要說明。
    /// </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>
        /// 必需的設計器變量。
        /// </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 類撰寫設計器支持所必需的
            ///
            this.label1.text="test";
            container.add(this);
            initializecomponent();

            //
            // todo: 在 initializecomponent 調用后添加任何構造函數代碼
            //
        }

        public abeencontrol()
        {
            /**////
            /// windows.forms 類撰寫設計器支持所必需的
            ///
            initializecomponent();
           

            //
            // todo: 在 initializecomponent 調用后添加任何構造函數代碼
            //
        }

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

        組件設計器生成的代碼#region 組件設計器生成的代碼
        /**//// <summary>
        /// 設計器支持所需的方法 - 不要使用代碼編輯器修改
        /// 此方法的內容。

            this.label1 = new system.windows.forms.label();

        private void button1_click(object sender, system.eventargs e)
        {

        }

        private void abeencontrol_load(object sender, system.eventargs e)
        {

    }
}
２、web　頁面調用active組件
　　注意web頁面調用時需要把active的.dll放到web的虛擬要目錄下。
<html>
    <head>
        <title>testactive</title>
        <meta name="generator" content="microsoft visual studio .net 7.1">
        <meta name="code_language" content="c#">

        <font face="arial" size="1">

            </object>
        </font>
        <form id="frm" name="frm">

            function doscript()
            {
                 mycontrol1.labeltext=frm.txt.value;
            }
           
            </script>
        </form>
    </body>
</html>
