Question

Im利用国家空间学会开发一台安装装置供我使用。我需要与这个安装厂商做的是检查80号港口是否可用,如果该港口没有向80号停靠的加工名称发出错误信息,则该港口是否可供使用。

我找到了一种办法,检查80港是否可用。为此,我使用了Ports.nsh作为原始材料:。

${If} ${TCPPortOpen} 80
 MessageBox MB_OK|MB_ICONSTOP "PORT 80 is already using by another program..."
 Abort
${EndIf}

但是,由于这一原因,我无法在该港口找到一个运行进程。我需要发出错误信息,例如:

//Skype is running on port 80 and close Skype to continue with the installation.

请允许我就此帮助我。感谢。

Dim WshShell, oExec, key
Set WshShell = CreateObject("WScript.Shell")
Set oExec = WshShell.Exec("netstat -o -n -a")

Dim values
values = checkPortStatus(oExec, key)
portInUse = values(0)
input = values(1)

If portInUse Then
  x = InStrRev(input, " ")

  ProcessID = Mid(input, x+1)

  commandTxt = "tasklist /FI " & Chr(34) & "PID eq " & ProcessID & Chr(34)

Dim oExec2, key2

    ExeName = Left(input2, y-1)
        WScript.StdOut.WriteLine "Port 80 is using by " & ExeName

 ## If we explicitly set a Success code then we can avoid this.
