如何获取网卡的型号和详细信息 mac地址等

[lpi]

获得地址：
1)在Visual Basic创建 Form1。
2)在Form1中添加一命令按钮，缺省名为Command1。
3)把下列代码放到Form1中说明部分。

Option Explicit
Private Const NCBASTAT = &H33
Private Const NCBNAMSZ = 16
Private Const HEAP_ZERO_MEMORY = &H8
Private Const HEAP_GENERATE_EXCEPTIONS = &H4
Private Const NCBRESET = &H32

Private Type NCB
　　ncb_command As Byte 'Integer
　　ncb_retcode As Byte 'Integer
　　ncb_lsn As Byte 'Integer
　　ncb_num As Byte ' Integer
　　ncb_buffer As Long 'String
　　ncb_length As Integer
　　ncb_callname As String * NCBNAMSZ
　　ncb_name As String * NCBNAMSZ
　　ncb_rto As Byte 'Integer
　　ncb_sto As Byte ' Integer
　　ncb_post As Long
　　ncb_lana_num As Byte 'Integer
　　ncb_cmd_cplt As Byte 'Integer
　　ncb_reserve(9) As Byte ' Reserved, must be 0
　　ncb_event As Long
End Type

Private Type ADAPTER_STATUS
　　adapter_address(5) As Byte 'As String * 6
　　rev_major As Byte 'Integer
　　reserved0 As Byte 'Integer
　　adapter_type As Byte 'Integer
　　rev_minor As Byte 'Integer
　　duration As Integer
　　frmr_recv As Integer
　　frmr_xmit As Integer
　　iframe_recv_err As Integer
　　xmit_aborts As Integer
　　xmit_success As Long
　　recv_success As Long
　　iframe_xmit_err As Integer
　　recv_buff_unavail As Integer
　　t1_timeouts As Integer
　　ti_timeouts As Integer
　　Reserved1 As Long
　　free_ncbs As Integer
　　max_cfg_ncbs As Integer
　　max_ncbs As Integer
　　xmit_buf_unavail As Integer
　　max_dgram_size As Integer
　　pending_sess As Integer
　　max_cfg_sess As Integer
　　max_sess As Integer
　　max_sess_pkt_size As Integer
　　name_count As Integer
End Type

Private Type NAME_BUFFER
　　name As String * NCBNAMSZ
　　name_num As Integer
　　name_flags As Integer
End Type

Private Type ASTAT
　　adapt As ADAPTER_STATUS
　　NameBuff(30) As NAME_BUFFER
End Type

Private Declare Function Netbios Lib "netapi32.dll" (pncb As NCB) As Byte
Private Declare Sub CopyMemory Lib "kernel32" Alias "RtlMoveMemory" _
　　(hpvDest As Any, ByVal hpvSource As Long, ByVal cbCopy As Long)
Private Declare Function GetProcessHeap Lib "kernel32" () As Long
Private Declare Function HeapAlloc Lib "kernel32" _
　　(ByVal hHeap As Long, ByVal dwFlags As Long, _
　　ByVal dwBytes As Long) As Long
Private Declare Function HeapFree Lib "kernel32" (ByVal hHeap As Long, _
　　ByVal dwFlags As Long, lpMem As Any) As Long

把下面的代码放入Command1_Click的事件中：

Private Sub Command1_Click()
　　Dim myNcb As NCB
　　Dim bRet As Byte
　　myNcb.ncb_command = NCBRESET
　　bRet = Netbios(myNcb)
　　myNcb.ncb_command = NCBASTAT
　　myNcb.ncb_lana_num = 0
　　myNcb.ncb_callname = "*　　　　　　 "
　　Dim myASTAT As ASTAT, tempASTAT As ASTAT
　　Dim pASTAT As Long
　　myNcb.ncb_length = Len(myASTAT)
　　Debug.Print Err.LastDllError
　　pASTAT = HeapAlloc(GetProcessHeap(), HEAP_GENERATE_EXCEPTIONS _
　　　　Or HEAP_ZERO_MEMORY, myNcb.ncb_length)
　　If pASTAT = 0 Then
　　　　Debug.Print "memory allcoation failed!"
　　　　Exit Sub
　　End If
　　myNcb.ncb_buffer = pASTAT
　　bRet = Netbios(myNcb)
　　Debug.Print Err.LastDllError
　　CopyMemory myASTAT, myNcb.ncb_buffer, Len(myASTAT)
　　MsgBox Hex(myASTAT.adapt.adapter_address(0)) & " " & _
　　　　Hex(myASTAT.adapt.adapter_address(1)) _
　　　　& " " & Hex(myASTAT.adapt.adapter_address(2)) & " " _
　　　　& Hex(myASTAT.adapt.adapter_address(3)) _
　　　　& " " & Hex(myASTAT.adapt.adapter_address(4)) & " " _
　　　　& Hex(myASTAT.adapt.adapter_address(5))
　　HeapFree GetProcessHeap(), 0, pASTAT
End Sub

4)按F5，运行该程序。
5)点击Command1。注意，网卡地址将在一信息框中显示出来。
