VS.Net C# 调用 Active 组件

　　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。
<html>
    <head>
        <title>testactive</title>
        <meta name="generator" content="microsoft visual studio .net 7.1">
        <meta name="code_language" content="c#">
        <meta name="vs_defaultclientscript" content="javascript">
        <meta name="vs_targetschema" content="http://schemas.microsoft.com/intellisense/ie5">
    </head>
    <body >
        <font face="arial" size="1">
            <object id="mycontrol1" name="mycontrol1" classid="http://localhost/webapplication1/activexdotnet.dll#activexdotnet.abeencontrol"

            </object>
        </font>
        <form id="frm" name="frm">
            <input type="text" name="txt" value="请输入数据：" id="text1">
            <input type="button" value="确定" id="button1" name="button1">
            <script type="text/javascript">
            function doscript()
            {
                 mycontrol1.labeltext=frm.txt.value;
            }
           
            </script>
        </form>
    </body>
</html>
