用Visual C#来增加数据记录

nextrec.Location = new System.Drawing.Point ( 205 , 312 );
nextrec.ForeColor = System.Drawing.Color.Black ;
nextrec.Size = new System.Drawing.Size ( 40 , 24 ) ;
firstrec.Text = "首记录";
firstrec.Click += new System.EventHandler(GoFirst);
previousrec.Location = new System.Drawing.Point ( 135 , 312 ) ;
previousrec.ForeColor = System.Drawing.Color.Black ;
l_booktitle.Location = new System.Drawing.Point ( 24 , 108 ) ;
l_booktitle.Text = "书 名：";
l_booktitle.Size = new System.Drawing.Size ( 112 , 20 ) ;
//把Dataset绑定books数据表
myCommand.Fill ( myDataSet , "books" ) ;
//关闭此OleDbConnection
myConn.Close ( ) ;
}
catch ( Exception e )
{
MessageBox.Show ( "连接错误! " + e.ToString ( ) , "错误" ) ;
}
}
private void InitializeComponent ( )
{
components = new ponentModel.Container ( ) ;
nextrec = new Button ( ) ;

//以下是对数据浏览的四个按钮进行初始化

//释放程序使用过的所以资源

二．用Visual C#往SQL SERVER数据库中插入记录：
（1）用Visual C#往Access 2000和SQL SERVER添加记录的主要区别在于使用了不同的数据库引擎。在编写程序之前，首先假设数据库服务器名称为：server1，要访问的数据库名称为：data1，数据表名称为：books。用户名为：sa。其中数据表的数据结构和Access 2000的表的结构相同。下面是程序中打开SQL SERVER的数据引擎程序代码：
string strCon = "Provider = SQLOLEDB.1 ; Persist Security Info = False ; User ID = sa ; Initial Catalog = data1 ; Data Source = server1 " ;
OleDbConnection myConn = new OleDbConnection ( strCon ) ;
nextrec.Font = new System.Drawing.Font ( "仿宋" , 8f ) ;
nextrec.Text = "下一条" ;
nextrec.Click += new System.EventHandler ( GoNext );
lastrec.Location = new System.Drawing.Point ( 275 , 312 ) ;
public static void Main ( ) {
Application.Run ( new DataAdd ( ) ) ;
}
public void GetConnected ( )
{
try{
// 设定数据连接字符串，此字符串的意思是打开Sql server数据库，服务器名称为server1,数据库为data1，用户名为sa。
lastrec.Text = "尾记录" ;
lastrec.Click += new System.EventHandler ( GoLast ) ;
//以下是对显示标签进行初始化
