active
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。

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";

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";
//

//
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。
