在編碼中不可否認(rèn)調(diào)用Active會給編程帶來很大便利，雖然微軟不太支持.net調(diào)用Active 組件。
本實(shí)例是一個簡單Web頁面調(diào)用Active組件的例子，實(shí)現(xiàn)把數(shù)據(jù)傳入并顯示在active組件里的控件中。
實(shí)例代碼如下：
1、建立Active組件（這里用.net c#創(chuàng)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(quán)限使它能在頁面上顯示。
using System;
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(shè)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(shè)計器支持所必需的
///
this.label1.Text="test";
container.Add(this);
InitializeComponent();
//
// TODO: 在 InitializeComponent 調(diào)用后添加任何構(gòu)造函數(shù)代碼
//
}
public AbeenControl()
{
/**////
/// Windows.Forms 類撰寫設(shè)計器支持所必需的
///
InitializeComponent();
//
// TODO: 在 InitializeComponent 調(diào)用后添加任何構(gòu)造函數(shù)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(shè)計器生成的代碼#region 組件設(shè)計器生成的代碼：
/**//// <summary>
/// 設(shè)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(nèi)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="點(diǎn)擊完成！";
}
private void AbeenControl_Load(object sender, System.EventArgs e)
{
}
}
}

2、web頁面調(diào)用Active組件
注意web頁面調(diào)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>
<form id="frm" name="frm">
