VS.Net C#调用Active组件

【IT168技术文档】

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.ComponentModel;

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.Button button1;
private System.Windows.Forms.GroupBox groupBox1;
/**//**//**//// <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
// 
}

...{

components.Dispose();
}
}
base.Dispose( disposing );
}

this.ResumeLayout(false);

}

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。
