flex部分代码如下:
mxml文件

fs.GetData();

flex里的services_config.xml这个文件是一个配置文件就好比asp.net里的webconfig意思差不多吧都是xml结构,这个文件要跟mxml文件放在一个路径下文件内容如下:
<?xml version="1.0" encoding="UTF-8"?> <services-config> <services> <service id="remoting-service" class="flex.messaging.services.RemotingService" messageTypes="flex.messaging.messages.RemotingMessage"> <destination id="fluorine"> <channels> <channel ref="my-amf"/> </channels> <properties> <source>*</source> </properties> </destination> </service> </services> <channels> <channel-definition id="my-amf" class="mx.messaging.channels.AMFChannel"> <endpoint uri="http://localhost:6199/WebSite2/Gateway.aspx" class="flex.messaging.endpoints.AMFEndpoint"/> </channel-definition> </channels> </services-config>
好了到现在为止flex部分的文件已经完全展现给大家了.
下面是asp.net部分
首先确定在机器里已经安装了fluorinefx,现在fluorinefx已经可以支持在vs2008中使用了
打开vs2008或vs2005以后在就会出现一个fluorinefx的选项,建立好以后就可以通过修改cs代码来实现连接数据库的功能
代码如下:
using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Data.SqlClient;//引用“System.Data.SqlClient”
using System.Collections;//引用“System.Collections”
using FluorineFx.Management.Web;
using FluorineFx;
/// <summary>
/// GetSQLServer2000Data 的摘要说明
/// </summary>
namespace remoting //名称空间,可自定义
{
[RemotingService()]
public class GetSQLServer2000Data
{
public GetSQLServer2000Data()
{
}
public DataSet GetData()//获得数据库数据
{
SqlConnection conn = new SqlConnection();//定义“SqlConnnection”类实例
//数据库连接字符串
conn.ConnectionString = "Data Source=.;Initial Catalog=School;Persist Security Info=True;User ID=sa;Password=sa";
//定义“SqlCommand”实例，从“Notes”表中取数据
SqlCommand command = new SqlCommand("select * from Notes", conn);
conn.Open();//打开连接
SqlDataAdapter da = new SqlDataAdapter();//定义“SqlDataAdapter”类实例
da.SelectCommand = command;//将“command”值传递给“SqlDataAdapter”的“SelectCommand”属性
DataSet ds = new DataSet();//定义“DataSet”类实例
da.Fill(ds, "tables");//取数据
//关闭数据库
conn.Close();
return ds;
}
public void InsertData(string title, string content, string publisher)//插入数据
{
SqlConnection conn = new SqlConnection();//定义“SqlConnnection”类实例
//数据库连接字符串
conn.ConnectionString = "Data Source=.;Initial Catalog=School;Persist Security Info=True;User ID=sa;Password=sa";
SqlCommand command = new SqlCommand("select Max(noteId) from Notes", conn);
conn.Open();//打开连接
SqlDataAdapter da = new SqlDataAdapter();//定义“SqlDataAdapter”类实例
da.SelectCommand = command;//将“command”值传递给“SqlDataAdapter”的“SelectCommand”属性
DataSet ds = new DataSet();//定义“DataSet”类实例
da.Fill(ds, "tables");//取数据
string newid = (Convert.ToInt32(ds.Tables["tables"].Rows[0][0].ToString()) + 1).ToString();
command = new SqlCommand("insert into Notes values('" + newid + "','" + title.Trim() + "','" + content.Trim() + "','" + publisher.Trim() + "')", conn);
command.ExecuteNonQuery();
conn.Close();
}
}
}
