Word VBA"默默地"检索IP地址

Question

我需要将IP地址拉出到VBA宏中.此代码有效,但命令对话框可以短暂显示,这看起来并不好看.我可以使用修改"静默"吗？

Sub getIP()

Set objShell = CreateObject("WScript.Shell")
Set objExecObject = objShell.Exec("%comspec% /c ipconfig.exe")
Do Until objExecObject.StdOut.AtEndOfStream
    strLine = objExecObject.StdOut.ReadLine()
    strIP = InStr(strLine, "Address")
    If strIP <> 0 Then
        IPArray = Split(strLine, ":")
        strIPAddress = IPArray(1)
    End If
Loop
SynapseForm.LabelIP.Caption = strIPAddress

End Sub

更新,找到一个使用Wscript.Shell写入临时文件的变体,这个"默默地"工作不如下面Remou的方法那么好

    Sub getIPAddress()

Dim IP_Address: IP_Address = GetIP()

If IP_Address = "0.0.0.0" Or IP_Address = "" Then
MsgBox "No IP Address found.", , ""
Else
MsgBox IP_Address
'MsgBox IP_Address, , "IP address"
End If

End Sub

Function GetIP()

Dim ws: Set ws = CreateObject("WScript.Shell")
Dim fso: Set fso = CreateObject("Scripting.FileSystemObject")

Dim TmpFile: TmpFile = fso.GetSpecialFolder(2) & "/ip.txt"
Dim ThisLine, IP

If ws.Environment("SYSTEM")("OS") = "" Then
ws.Run "winipcfg /batch " & TmpFile, 0, True
Else
ws.Run "%comspec% /c ipconfig > " & TmpFile, 0, True
End If

With fso.GetFile(TmpFile).OpenAsTextStream
Do While Not .AtEndOfStream
ThisLine = .ReadLine
If InStr(ThisLine, "Address") <> 0 Then
IP = Mid(ThisLine, InStr(ThisLine, ":") + 2)
End If
Loop
.Close
End With

'WinXP (NT? 2K?) leaves a carriage return at the end of line
If IP <> "" Then
If Asc(Right(IP, 1)) = 13 Then IP = Left(IP, Len(IP) - 1)
End If

GetIP = IP

fso.GetFile(TmpFile).Delete

Set fso = Nothing
Set ws = Nothing

End Function

我认为这可能更容易,它使用WMI.

strComputer = "."
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\CIMV2")
Set colItems = objWMIService.ExecQuery( _
    "SELECT * FROM Win32_NetworkAdapterConfiguration", , 48)
For Each objItem In colItems
    If Not IsNull(objItem.IPAddress) Then
        ''Commented line
        ''Debug.Print "IPAddress: " & Join(objItem.IPAddress, ",")
        ''Message box
        MsgBox "IPAddress: " & Join(objItem.IPAddress, ",")
        ''String for later use
        strIPAddress = strIPAddress & Join(objItem.IPAddress, ",")
    End If
Next
''Later
SynapseForm.LabelIP.Caption = strIPAddress
