C#

// CAN message

[StructLayout(LayoutKind.Sequential, Pack = 1)]

public struct TPCANMsg

{

public uint ID; // 11/29 bit identifier

public byte MSGTYPE; // Bits from MSGTYPE_*

public byte LEN; // Data Length Code of the Msg (0..8)

[ MarshalAs( UnmanagedType.ByValArray, SizeConst = 8 )]

public byte[] DATA ; //Data 0 .. 7

}

So In labView....

So I've created a Cluster with a U16(ID), U8 (MSGTYPE),U8(LEND) and an Array of 8 U8s (DATA),

It is not possible to create an equivalent to your C# structure in Labview.

What Labview creates will be something like this:

(C++-Syntax)

struct TPCANMsg{

unsigned int ID;

char MSGTYPE;

char LEN;

LVArray** Data;

}

struct LVArray{

int Length;

char Data[1];

}

You also have to check that your dll uses 1byte struct member alignment. This is what LabView expects.
