VBScript-检查端口是否正在侦听+窗口以通知用户

netstat vbscript service

我有一个关于vbs的问题。我需要监视端口5900上的连接是否已建立。脚本应作为服务运行,并应经常检查连接是否已建立。当建立连接时,它应该打开一个小窗口(不允许用户交互(例如,无法关闭,没有“确定”按钮等)),其中包含类似“建立连接//[连接的设备的主机名]”的内容。如果连接已关闭,则小窗口也应关闭。

如果我运行脚本并且建立了连接,ATM就可以弹出消息

迄今为止我的代码:

Dim ObjExec
Dim strFromProc

Set objShell = CreateObject("WScript.Shell")
Set ObjExec = objShell.Exec("%comspec% /c netstat -a | find ""ESTABLISHED"" | find "":5900""" )

Do Until ObjExec.Stdout.atEndOfStream
    strFromProc = strFromProc & ObjExec.StdOut.ReadLine & vbNewLine
    WScript.Echo "Connection Established"
Loop

顺致敬意,

尝试这样的方法:使用 .Popup method

Option Explicit
Dim ObjExec,objShell,strFromProc,intButton,Port
Port = "5900"
Set objShell = CreateObject("WScript.Shell")
Set ObjExec = objShell.Exec("%comspec% /c netstat -a | find "& DblQuote("ESTABLISHED") & "| find " & DblQuote(Port) &"")
strFromProc = ObjExec.StdOut.ReadAll
If Instr(strFromProc,"ESTABLISHED") > 0 Then
    intButton = objShell.Popup(strFromProc,3,"Connection Established @ Port "& Port &"",vbInformation)
Else    
    intButton = objShell.Popup("Connection Not Established @ Port "& Port,3,"Connection Not Established @ Port "& Port &"",vbExclamation)
End If  
'****************************************************************
Function DblQuote(Str)
    DblQuote = Chr(34) & Str & Chr(34)
End Function
'****************************************************************

如果你想避免使用黑色控制台;试试这个方法:

Option Explicit
Dim ObjExec,strCommand,OutPutData,objShell,strFromProc,intButton,Port
Port = "5900"
Set objShell = CreateObject("WScript.Shell")
strCommand = "%comspec% /c netstat -a | find "& DblQuote("ESTABLISHED") & "| find " & DblQuote(Port) &""
OutPutData = Run_Cmd(strCommand)
If Instr(OutPutData,"ESTABLISHED") > 0 Then
    intButton = objShell.Popup(OutPutData,3,"Connection Established @ Port "& Port &"",vbInformation)
Else    
    intButton = objShell.Popup("Connection Not Established @ Port "& Port,3,"Connection Not Established @ Port "& Port &"",vbExclamation)
End If  
'****************************************************************
Function DblQuote(Str)
    DblQuote = Chr(34) & Str & Chr(34)
End Function
'****************************************************************
Function Run_Cmd(strCommand)
    On Error Resume Next
    Const ForReading = 1
    Const TemporaryFolder = 2
    Const WshHide = 0
    Dim wsh, fs, ts
    Dim strTempFile,strFile, strData
    Set wsh = CreateObject("Wscript.Shell")
    Set fs = CreateObject("Scripting.FileSystemObject")
    strTempFile = fs.BuildPath(fs.GetSpecialFolder(TemporaryFolder).Path, fs.GetTempName)
    strFile = fs.BuildPath(fs.GetSpecialFolder(TemporaryFolder).Path, "result.txt")
    wsh.Run "cmd.exe /c " & strCommand & " > " & DblQuote(strTempFile) & "2>&1", WshHide, True
    wsh.Run "cmd.exe /u /c Type " & DblQuote(strTempFile) & " > " & DblQuote(strFile) & "", WshHide, True
    Set ts = fs.OpenTextFile(strFile, ForReading,true,-1)
    strData = ts.ReadAll
    Run_Cmd = strData
    ts.Close
    fs.DeleteFile strTempFile
    fs.DeleteFile strFile
End Function
