请教一下，如何在Win7下实时流量监控。

看过别人的源代码试过 iphlpapi.dll 在WIN7下不行，XP下可以
还试过其它的源代码，偏差值太大了。

Declare Function GetNetworkParams Lib "iphlpapi.dll" (FixedInfo As Any, pOutBufLen As Long) As Long
Declare Function GetIfTable Lib "iphlpapi.dll" (ByRef pIfTable As MIB_IFTABLE, ByRef pdwSize As Long, _
ByVal bOrder As Long) As Long
Declare Function GetIfEntry Lib "iphlpapi.dll" (pIfRow As MIB_IFROW) As Long
Type MIB_IFROW
'保存结果信息
wszName(0 To 511) As Byte '接口名称的Unicode字符串，必须为512字节
dwIndex As Long '接口编号
dwType As Long '接口类型，参看IP_ADAPTER_INFO类型的Type成员
dwMtu As Long '最大传输单元
dwSpeed As Long '接口速度(字节)
dwPhysAddrLen As Long '由bPhysAddr获得的物理地址有效长度
bPhysAddr(0 To 7) As Byte '物理地址
dwAdminStatus As Long '接口管理状态
dwOperStatus As Long '操作状态，以下值之一:
dwLastChange As Long '操作状态最后改变的时间
dwInOctets As Long '总共收到(字节)
dwInUcastPkts As Long '总共收到(unicast包)
dwInNUcastPkts As Long '总共收到(non-unicast包)，包括广播包和多点传送包
dwInDiscards As Long '收到后丢弃包总数(即使没有错误)
dwInErrors As Long '收到出错包总数
dwInUnknownProtos As Long '收到后因协议不明而丢弃的包总数
dwOutOctets As Long '总共发送(字节)
dwOutUcastPkts As Long '总共发送(unicast包)
dwOutNUcastPkts As Long '总共发送(non-unicast包)，包括广播包和多点传送包
dwOutDiscards As Long '发送丢弃包总数(即使没有错误)
dwOutErrors As Long '发送出错包总数
dwOutQLen As Long '发送队列长度
dwDescrLen As Long 'bDescr部分有效长度
bDescr(0 To 255) As Byte '接口描述
End Type
Type MIB_IFTABLE '包含结果表
dwNumEntries As Long '当前网络接口的总数
MIB_Table(9) As MIB_IFROW '指向一个包含MIB_IFROW类型的指针
End Type

'由Net.dwNumEntries获得接口数量，然后用for…next循环获取每个接口信息:
