在.NET中调用DataWindow操作数据库

Sybase在2004/1/19日推出了Pb 10 beta1版本，其中包含DataWindow.NET 1.0,这真是一个另人兴奋的消息! 在PB市场日益萎缩的今天，在.NET大行其道的今天Sybase公司终于推出了DataWindow.NET,它支持DataWindow绝大部份原有事件和属性，PB技术终于可以重新又派上用场了!!

下过来安装程序，便急不可待的在VS.NET2003下面做了一个简单的例子，发现真的很好用!源代码、界面如下：



using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;

namespace cjgl.Report
{
/// <summary>
/// DataWindowTest 的摘要说明。
/// </summary>
public class DataWindowTest : System.Windows.Forms.Form
{
private Sybase.DataWindow.DataWindowControl dw;
private Sybase.DataWindow.Transaction Trans;
private System.Windows.Forms.Button btnRetrieve;
private System.Windows.Forms.Button btnDelete;
private System.Windows.Forms.Button btnInsert;
private System.Windows.Forms.Button btnSave;
private System.ComponentModel.IContainer components;

public DataWindowTest()
{
//
// Windows 窗体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 );
}
