NICのMacアドレスを取得する: Win32_NetworkAdapterConfigration
■Topics
NICのMacアドレスを取得するサンプルです。Win32_NetworkAdapterConfigrationクラスを使用します。
Private Sub Command1_Click()
Dim NicSet As SWbemObjectSet
Dim Nic As SWbemObject
Dim Locator As SWbemLocator
Dim Service As SWbemServices
Dim MesStr As String
Set Locator = New WbemScripting.SWbemLocator
Set Service = Locator.ConnectServer
Set NicSet = Service.ExecQuery _
("Select * From Win32_NetworkAdapterConfiguration")
For Each Nic In NicSet
If Nic.IPEnabled = True Then
MesStr = MesStr + _
"NICの種類：" + Nic.Description + vbCrLf + _
"NICのMacアドレス：" + Nic.MACAddress + vbCrLf
End If
Next
MsgBox "NicのMacアドレスです。" + vbCrLf + _
vbCrLf + MesStr + vbCrLf + "ですよ。"
Set NicSet = Nothing
Set Nic = Nothing
Set Locator = Nothing
Set Service = Nothing
End Sub
Dim NicSet As SWbemObjectSet
Dim Nic As SWbemObject
Dim Locator As SWbemLocator
Dim Service As SWbemServices
Dim MesStr As String
Set Locator = New WbemScripting.SWbemLocator
Set Service = Locator.ConnectServer
Set NicSet = Service.ExecQuery _
("Select * From Win32_NetworkAdapterConfiguration")
For Each Nic In NicSet
If Nic.IPEnabled = True Then
MesStr = MesStr + _
"NICの種類：" + Nic.Description + vbCrLf + _
"NICのMacアドレス：" + Nic.MACAddress + vbCrLf
End If
Next
MsgBox "NicのMacアドレスです。" + vbCrLf + _
vbCrLf + MesStr + vbCrLf + "ですよ。"
Set NicSet = Nothing
Set Nic = Nothing
Set Locator = Nothing
Set Service = Nothing
End Sub
実行すると搭載されているNICのMacアドレスを表示します。
