dllcall  调用 Iphlpapi.dll  中的 CreateIpForwardEntry  函数修改路由表，应该怎么调用。这两天把论坛里关于dllcall的贴子都翻完了。还是没搞懂。。

写到一下程度可能运行不正确具体哪些参数怎么填我也懒得翻资料了
Local $str =" dword dwForwardDest;dword dwForwardMask;dword dwForwardNextHop;dword dwForwardIfIndex;dword dwForwardType;dword dwForwardProto;dword dwForwardPolicy;dword dwForwardAge;dword dwForwardNextHopAS;dword dwForwardMetric1;dword dwForwardMetric2;dword dwForwardMetric3;dword dwForwardMetric4;dword dwForwardMetric5"
Local $a = DllStructCreate($str)
DllStructSetData($a, "dwForwardDest", inet_addr("1.2.3.4") );目的地址
DllStructSetData($a, "dwForwardMask",  inet_addr("255.255.255.0"));掩码
DllStructSetData($a, "dwForwardNextHop", inet_addr("1.10.10.10") );下一跳
DllStructSetData($a, "dwForwardIfIndex", 1);网卡索引
DllStructSetData($a, "dwForwardType", 4)
DllStructSetData($a, "dwForwardProto",3)
DllStructSetData($a, "dwForwardPolicy ",0)
DllStructSetData($a, "dwForwardAge",0)
DllStructSetData($a, "dwForwardNextHopAS",0)
DllStructSetData($a, "dwForwardMetric1", 10 )

DllStructSetData($a, "dwForwardMetric3", 0xFFFFFFFF)
DllStructSetData($a, "dwForwardMetric4", 0xFFFFFFFF)
DllStructSetData($a, "dwForwardMetric5", 0xFFFFFFFF)
Local $dll = DllOpen("Iphlpapi.dll")
Local $aResult = DllCall($dll, "dword", "CreateIpForwardEntry", "ptr",DllStructGetPtr($a))
        If @error Then 
        MsgBox (0,"","错误")
Else
        MsgBox(0,"","成功返回结果："&$aResult[0]&"         "&$aResult[1]);$aResult[0]就是返回值
EndIf
DllClose ($dll)


Func inet_addr($sIP);转换ip格式
$hWs2_32 = DllOpen( "Ws2_32.dll" )
$iRet = DllCall($hWs2_32, "uint", "inet_addr", "str", $sIP)
DllClose($hWs2_32)
If $iRet[ 0 ] = 0xffffffff Then Return False
Return $iRet[ 0 ]

    IpForwardTable.dwForwardIfIndex = g_dwIndex;
    IpForwardTable.dwForwardType = 4;  //路由类型 3是最终目标，4是非最终目标,我们加的路由都是要过网关的，设成4 
    IpForwardTable.dwForwardProto = 3;  //路由协议，这个在这个函数里要设成3 
     //IpForwardTable.dwForwardAge = NULL;
     //IpForwardTable.dwForwardNextHopAS = NULL;
    IpForwardTable.dwForwardMetric1 = 1; 
    IpForwardTable.dwForwardMetric2 = 0xFFFFFFFF;
    IpForwardTable.dwForwardMetric3 = 0xFFFFFFFF;  
    IpForwardTable.dwForwardMetric4 = 0xFFFFFFFF;   
    IpForwardTable.dwForwardMetric5 = 0xFFFFFFFF; 
    DWORD dwRetVal = CreateIpForwardEntry(&IpForwardTable);
    return dwRetVal;
}

这个是在网上找到的代码，看不懂。。

我也纠结了 楼主为什么不用DOS命令解决 这种微软自己编的东西基本上就是对这一函数非常熟悉才能用的好

用批处理,或是au3.如果上千条路由命令.要半小时以上!!!!

还是不行啊，谁帮我看看啊？返回值87，提交了无效参数。。

MIB_IPFORWARDROW IpForwardTable 这两个又是个什么情况？
