VB如何执行Telnet命令（不出现命令提示符窗口）
不希望用生成批处理BAT后用Shell去调用，然后隐藏 提示符窗口 的做法！
Telnet进去后，还得执行3个命令，用VBS脚本我会做，但是运行了还是会出现 提示符窗口
我希望做出来得结果是：能在VB的TEXT文本框里看到执行后返回的数据，全部过程不需要调用到CMD提示符窗口
Telnet 命令如下：
-----------------------------------------------------
telnet members.3322.org 80
GET /dyndns/update?system=dyndns&hostname=myDB.3322.org&wildcard=OFF&offline=NO HTTP/1.1
Host: members.3322.org
Authorization: Basic bXlEQjoxMjM0NTY=
------------------------------------------------------
VBS脚本是这样的：
--------------------------------------------------
Set WshShell = CreateObject("WScript.Shell")
WshShell.Run "telnet members.3322.org 80"
WScript.Sleep(1200)
WshShell.SendKeys "GET /dyndns/update?system=dyndns&hostname=myDB.3322.org&wildcard=OFF&offline=NO HTTP/1.1{enter}"
WScript.Sleep(500)
WshShell.SendKeys "Host: members.3322.org{enter}"
WScript.Sleep(500)
WshShell.SendKeys "Authorization: Basic bXlEQjoxMjM0NTY={enter}"
WScript.Sleep(500)
WshShell.SendKeys "{enter}"
---------------------------------------------------
希望高手指教！！！！！

一个text1控件和一个winsock1控件
大致代码就这样子
Option Explicit
Private Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)
Private Sub Form_Load()
Winsock1.Protocol = sckTCPProtocol
Winsock1.Connect "members.3322.org", 80
End Sub
Private Sub Winsock1_Connect()
Dim Str As String
Str = "GET /dyndns/update?system=dyndns&hostname=myDB.3322.org&wildcard=OFF&offline=NO HTTP/1.1 " & vbCrLf
Str = Str & "Host: members.3322.org" & vbCrLf
Str = Str & "Authorization: Basic bXlEQjoxMjM0NTY=" & vbCrLf
Winsock1.SendData Str
End Sub
Private Sub Winsock1_DataArrival(ByVal bytesTotal As Long)
Dim Data As String
Winsock1.GetData Data
Text1.Text = Data
End Sub

可以用winsock控件直接做
telnet 协议你可以用sanddata 一行一行给他发指令的,用vbcrlf加在每行结尾就行了
[其他解释]
能否用 API ，别用winsock控件呢？
带多个控件感觉麻烦，HOHO~~~~
[其他解释]
用API可以实现啊。不过只实现登录，一点用也没有，而实现一个完整的Telnet客户端，工作量又太大，所以建议楼主不妨自己GOOGLE一下，慢慢地实现一个。
[其他解释]
2楼的代码也不正确，没通过
[其他解释]
报错吗?
我这里可以运行的啊.
网上有用api实现winsock功能的类,代码很多啊,关键分清楚要做的是什么,陷在那堆API代码里是不是值得
[其他解释]
没报错，但是运行后没产生连接，TEXT里也没接收到返回的数据
[其他解释]
路过,顶一下

VBS 改为如下：
Set WshShell = Wscript.CreateObject("WScript.Shell")
a = WshShell.Run ("telnet members.3322.org 80" , 0)
WScript.Sleep(1200)
WshShell.SendKeys "GET /dyndns/update?system=dyndns&hostname=myDB.3322.org&wildcard=OFF&offline=NO HTTP/1.1{enter}"
WScript.Sleep(500)
WshShell.SendKeys "Host: members.3322.org{enter}"
WScript.Sleep(500)
WshShell.SendKeys "Authorization: Basic bXlEQjoxMjM0NTY={enter}"
WScript.Sleep(500)
WshShell.SendKeys "{enter}"[其他解释]
用管道可以完成你的这个任务
pipe技术
等明天我找下代码来再给你
[其他解释]
一是可以用vbhide的方式启动窗口，然后用>重定向符输出到txt文件。
另外一个比较高级的技术
是使用管道技术
VB下用管道方式运行dos命令，可以把dos命令返回的结果显示在自己的窗口上。
就相当于在dos窗口和vb程序间建立了一个通道
在管道里开启一个进程，
让程序在管道里运行，
等待进程结束，
后将留在管道里的程序执行信息文件读取出来。

我倒了,以 g 或者 p 打头的数据包winsock控件居然拒发~ 程序没有错,控件拒绝发送

自己找到解决方法了，全部API实现
