How to use DllStructGetData for enumerated type in MIB_IF_ROW2?

[d77fn]

Should I use ulong for NET_LUID? (Well I find it should be uint64)
Things like "NET_LUID InterfaceLuid;" is not like "type name" style. They are two name. The type name "NET_LUID" is defined in other file.
So I should be lookup every type if they are not explicit written?
If I just write DllStructCreate(NET_IFINDEX InterfaceIndex; )  will it work!? Should I include some .h file?! Will it automatically find the correct type?
And the I don't know how to do with enum type.

What about that sub-struct started with BOOLEAN which 1st one is HardwareInterface : 1; And it's ended with InterfaceAndOperStatusFlags;
Should this "InterfaceAndOperStatusFlags" write inside DllStructCreate?

What about NDIS_MEDIUM MediaType;? It's a NDIS_MEDIUM type and is a enum!!!

typedef enum _NDIS_MEDIUM
{
    NdisMedium802_3,
    NdisMedium802_5,
    NdisMediumFddi,
    NdisMediumWan,
    NdisMediumLocalTalk,
    NdisMediumDix,              // defined for convenience, not a real medium
    NdisMediumArcnetRaw,
    NdisMediumArcnet878_2,
    NdisMediumAtm,
    NdisMediumWirelessWan,
    NdisMediumIrda,
    NdisMediumBpc,
    NdisMediumCoWan,
    NdisMedium1394,
    NdisMediumInfiniBand,
#if ((NTDDI_VERSION >= NTDDI_VISTA) || NDIS_SUPPORT_NDIS6)
    NdisMediumTunnel,
    NdisMediumNative802_11,
    NdisMediumLoopback,
#endif // (NTDDI_VERSION >= NTDDI_VISTA)

#if (NTDDI_VERSION >= NTDDI_WIN7)
    NdisMediumWiMAX,
    NdisMediumIP,
#endif

    NdisMediumMax               // Not a real medium, defined as an upper-bound
} NDIS_MEDIUM, *PNDIS_MEDIUM;

No, it won't work. You should spend some time to understand the basics of AutoIt and then how conversions from Windows API types to AutoIt types are done. Also you can check this repository with some AHK code that use similar data types like AutoIt. However don't take them blindly, for example NET_LUID it clearly unsigned not signed.

Hello just converted it for fun.

Local $sTag_NDIS_MEDIUM = "uint64 InterfaceLuid;int InterfaceIndex;dword Data1InterfaceGuid; word Data2InterfaceGuid; word Data3InterfaceGuid; byte Data4InterfaceGuid[8];wchar Alias[257];wchar Description[257];ulong PhysicalAddressLength;" & _
        "byte PhysicalAddress[32];byte PermanentPhysicalAddress[32];ulong Mtu;ulong Type;int TunnelType;int MediaType;int PhysicalMediumType;int AccessType;int DirectionType;" & _
        "boolean HardwareInterface;boolean FilterInterface;boolean ConnectorPresent;boolean NotAuthenticated;boolean NotMediaConnected;boolean Paused;boolean LowPower;boolean EndPointInterface;" & _
        "int OperStatus;int AdminStatus;int MediaConnectState;dword Data1NetworkGuid; word Data2NetworkGuid; word Data3NetworkGuid; byte Data4NetworkGuid[8];int ConnectionType;" & _

So If I don't use emulated type, I can just write a wrong type like "int" and leave if alone?
I see you don't use STRUCT ... ENDSTRUCT for booleans. Is it still work?

Do you mean an enumeration? - These are all usually 32bit values, as long as the lengths match you should be OK.

I could be doing something bad, but I've never really used the struct - end struct tags... 

The only thing to watch when dealing with odd lengths in the middle of a struct is alignment. You may end up with 00s appearing in the middle to move a value up to the next dword or something. I've been caught before, the struct was fine in 32bit, but it broke when compiling as 64bit. (but you can use the align tag to get out of that one!)

You must be aware of bit fields declarations. For InterfaceAndOperStatusFlags it will be used one byte, not 8 bytes:

struct {
    BOOLEAN HardwareInterface : 1;
    BOOLEAN FilterInterface : 1;
    BOOLEAN ConnectorPresent : 1;
    BOOLEAN NotAuthenticated : 1;
    BOOLEAN NotMediaConnected : 1;
    BOOLEAN Paused : 1;
    BOOLEAN LowPower : 1;
    BOOLEAN EndPointInterface : 1;
  } InterfaceAndOperStatusFlags;

Local $sTAG_InterfaceAndOperStatusFlags = "boolean HardwareInterface;boolean FilterInterface;boolean ConnectorPresent;boolean NotAuthenticated;boolean NotMediaConnected;boolean Paused;boolean LowPower;boolean EndPointInterface;"
Local $tInterfaceAndOperStatusFlags = DllStructCreate($sTAG_InterfaceAndOperStatusFlags)

ConsoleWrite(DllStructGetSize($tInterfaceAndOperStatusFlags) & @CRLF)
