Borland的C# Builder是一个基于C#语言的编程工具，C# Builder允许开发者用Java或CORBA工具开发，C# Builder同时也具有从多种数据库中读取数据的能力，可以混合和适应不同开发标准的能力。本文向大家介绍怎样用Borland C# Builder编写一个信箱监视程序， 程序主要是通过WinSock来进行网络通信。要实现这个程序，应对POP3协议有一定的了解，下面是对POP3协议的一个粗略的介绍，读者可以参看RFC 1225更为详细地了解该协议。
一、POP3协议简单介绍
POP3服务器程序通常在TCP端口110提供服务。当客户想要使用服务时，它便与服务器建立一个TCP连接。一旦连接建立，POP3服务器就向客户发送一条欢迎消息。然后客户开始给服务器发送命令，服务器则给出相应的回答。POP3的命令由一个关键词或者关键词加参数组成。每个命令以回车换行（0xD0xA）作为结束标志。对于所有的命令，POP3服务器都会提供一个回答。服务器的回答由一个状态标志加一些附加信息组成。目前使用的两个标志是“＋OK”和“－ERR”，分别表示客户的命令是否合法。所有的回答也是以回车换行结束。与本文讨论的话题相关的四个POP3命令是USER、PASS、STAT和QUIT。
USER命令
格式USER name
其中name是用户在该POP3服务器上的用户标识。客户应该在接到服务器的欢迎消息后或者在上一个USER或者PASS失败之后可以发送此命令。
PASS命令
格式PASS string
其中string为该用户的密码。客户在发送了USER命令并且收到了＋OK的回答之后方可发送此命令。如果用户名和密码都正确，服务器回答＋OK，否则－ERR。
STAT命令
格式STAT
STAT命令来查看邮箱的情况。STAT命令的回应中有两个数字，分别表示邮件的数量和邮件的大小。
QUIT命令
从POP3服务器上退出登录。
二、POP3信箱的监视程序分析
我们准备的做的程序要实现以下功能：
1.托盘图标，程序一运行，只显示一托盘图标，右键点击托盘图标可弹出菜单。
2.获取邮件数量，根据POP3协议，得到邮件的数量。
3.读取和写注册表，注册表中保存服务器、用户名、密码等设置。
4.用户提示信息，这里我们做一个与MSN一样的提示窗口。
三、程序实现
下面我们就不妨着手我们的程序。首先，打开Borland C# builder，新建一个项目，菜单 File->C# Applicaion 项目的名称不妨设为"chkpop3"，图示如下：
[ 相关贴图 ]
设计主窗口，如下图：
[ 相关贴图 ]
主要包括五个文本框，五个标签，三个按钮，一个选择框和一个timer。
WinForm设置如下：
text:收取邮件
startPosition:CenterScreen
MaximizeBox:false
三个按钮:
最小化按钮：最小化窗口，这里就是隐藏主窗口。
取邮件按钮：实现取得POP3信箱中的邮件数量，并用信息窗口提示。
应用按钮：保存设置到注册表中
timer1的功能：完成在一定时间间隔内取POP3信箱中邮件数量。
1.托盘的实现：
从tool palette选择组件contextMenu(加两个菜单项，设置和退出)、notifyIcon(text设为：邮箱检测，图标ICON选择一个16x16的小图标即可，contextMenu设为前面加入的contextMenu1，Visible设为true) 这样一个完整的托盘程序就设好了。
2.用户提示信息的实现：
新建一窗口WinForm1，把窗体的FormBorderStyle属性设置为None（无边框模式），然后把TopMost属性（总在最上方）属性设置为True，把ShowInTaskbar属性(是否在 Windows 任务栏中显示窗体)设置为False，并在窗体上加上一文字标签，将窗体的背景设置为你想要的图片和合适的大小。最后再放上三个Timer控件，其中，timer1控制窗体滚出的动画，timer2控制窗体停留时间，timer3控制窗体的滚入动画，将它们的Interval属性设置为10，如图：

3.获取邮件数量的实现，代码见下：
string str_server;
if ((tB_server.Text!="") && (tB_user.Text!="") && (tB_pwd.Text!=""))
{
TcpClient tcpc = new TcpClient(tB_server.Text,110);
Byte[] outbytes;
string input;
NetworkStream ns = null;
try{
ns = tcpc.GetStream();
StreamReader sr = new StreamReader(ns);
tB_status.Text=sr.ReadLine();
input = "USER " + tB_user.Text + "\r\n";
outbytes = System.Text.Encoding.ASCII.GetBytes(input.ToCharArray());
ns.Write(outbytes,0,outbytes.Length)
tB_status.Text=tB_status.Text+"\r\n"+sr.ReadLine();
input = "PASS " + tB_pwd.Text + "\r\n";
outbytes = System.Text.Encoding.ASCII.GetBytes(input.ToCharArray());
ns.Write(outbytes,0,outbytes.Length)
tB_status.Text=tB_status.Text+"\r\n"+sr.ReadLine();
input = "STAT" + "\r\n";
outbytes = System.Text.Encoding.ASCII.GetBytes(input.ToCharArray());
ns.Write(outbytes,0,outbytes.Length)
str_server=sr.ReadLine();
str_num="";
if (str_server.StartsWith("+OK")){
str_num=str_server.Split(' ')[1];
} else str_num="";
tB_status.Text=tB_status.Text+"\r\n"+"A:"+str_server;
input = "QUIT" + "\r\n";
outbytes = System.Text.Encoding.ASCII.GetBytes(input.ToCharArray());
ns.Write(outbytes,0,outbytes.Length)
tB_status.Text=tB_status.Text+"\r\n"+"B:"+sr.ReadLine();
}
catch(InvalidOperationException ioe){
tB_status.Text="Could not connect to mail server";
}
if (str_num!="") {
WinForm1 form = new WinForm1();
form.str_num=str_num;
form.ScrollShow();
}
程序与邮件服务器建立一个TCP连接，然后发送POP3的一些命令，取到服务器传回的信息，得到邮件的数量。
STAT命令的回应中有两个数字，分别表示邮件的数量和邮件的大小。一般格式是这样的“+OK 数量 大小”
所以，只要根据服务器返回的信息，提取+OK，然后再按空格分隔得到数量。代码见上。
4.注册表的读写：
我们知道，要实现程序在开机后自己运行，可以通过写注册表HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run实现
另外，为了方便用户，我们把邮件服务器，用户,密码等信息存入注册表，不用每次都再输一次。
保存信息代码如下：
RegistryKey rk;
Registry.CurrentUser.CreateSubKey("Software\\yousoft");
rk=Registry.CurrentUser.OpenSubKey("Software\\yousoft",true);
rk.Setvalue("server",tB_server.Text);
rk.Setvalue("user",tB_user.Text);
rk.Setvalue("pwd",tB_pwd.Text);
rk.Setvalue("interval",tB_mins.Text);
if (cB_autorun.Checked) {
rk=Registry.CurrentUser.OpenSubKey("Software\\Microsoft\\Windows\\CurrentVersion\\Run",true);
rk.Setvalue("chkmail",Application.ExecutablePath);
} else
{
rk=Registry.CurrentUser.OpenSubKey("Software\\Microsoft\\Windows\\CurrentVersion\\Run",true);
rk.Deletevalue("chkmail");
}
rk.Close();
启动程序时读入信息：
private void WinForm_Load(object sender, System.EventArgs e)
{
RegistryKey rk;
rk=Registry.CurrentUser.OpenSubKey("Software\\yousoft",false);
object srv=rk.Getvalue("server");
if (srv!=null) tB_server.Text=srv.ToString();
object usr=rk.Getvalue("user");
if (usr!=null) tB_user.Text=usr.ToString();
object pwd=rk.Getvalue("pwd");
if (pwd!=null) tB_pwd.Text=pwd.ToString();
object mins=rk.Getvalue("interval");
if (mins!=null) tB_mins.Text=mins.ToString();
rk.Close();
}
