VS.Net C#调用Active组件

2010-08-28 10:50:52来源:西部e网作者:

在编码中不可否认调用Active会给编程带来很大便利,虽然微软不太支持.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。
