1)在Visual Basic生成標準的EXE文件。缺省創建 Form1。
2)在Form1中添加一命令按鈕,缺省名為Command1。
3)把下列代碼放到Form1中說明部分。

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

Private Type ADAPTER_STATUS
  adapter_address(5) As Byte 注釋:As String * 6
  rev_major As Byte 注釋:Integer
  reserved0 As Byte 注釋:Integer
  adapter_type As Byte 注釋:Integer
  rev_minor As Byte 注釋: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

把下面的代碼放入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 Su
5)點擊Command1。注意,網卡地址將在一信息框中顯示出來。
