| 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 ExplicitPrivate Const NCBASTAT = &H33Private Const NCBNAMSZ = 16Private Const HEAP_ZERO_MEMORY = &H8Private Const HEAP_GENERATE_EXCEPTIONS = &H4Private Const NCBRESET = &H32Private 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 LongEnd TypePrivate 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 IntegerEnd TypePrivate Type NAME_BUFFER name As String * NCBNAMSZ name_num As Integer name_flags As IntegerEnd TypePrivate Type ASTAT adapt As ADAPTER_STATUS NameBuff(30) As NAME_BUFFEREnd TypePrivate Declare Function Netbios Lib "netapi32.dll" (pncb As NCB) As BytePrivate 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 LongPrivate Declare Function HeapAlloc Lib "kernel32" (ByVal hHeap As Long, ByVal dwFlags As Long, ByVal dwBytes As Long) As LongPrivate 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!"
