如何通过VB获取网卡地址

1)在Visual Basic生成标准的EXE文件。缺省创建 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 Su 5)点击Command1。注意，网卡地址将在一信息框中显示出来。
