Status Bitfields - neoVI API

There are two status bitfields in the message structures that define specific attributes of the message. The two status bitfields are named StatusBitfield and StatusBitfield1.

Examples

C/C++ Example

Determining if we there's an error in the message (This is indicated by SPY_STATUS_GLOBAL_ERR bit set)

if (mMsg.StatusBitField & SPY_STATUS_GLOBAL_ERR)
{
 // This message has an error in it
}

Visual Basic .NET Example

Determining if we transmitted a message (This is indicated by icsSpyStatusTx bit set)

If (Msg.StatusBitField And icsSpyDataStatusBitfield.icsSpyStatusTx) > 0 Then
        '// The message was transmitted by us
End If

Transmitting a CAN Extended ID Remote Frame

'// Load the message to be transmitted ArbID = FF extended remote frame with DLC=4
With stMessagesTx
    .ArbIDOrHeader = &HFF
    .NumberBytesData = 4
    .StatusBitField = icsSpyDataStatusBitfield.icsSpyStatusXtdFrame + icsSpyDataStatusBitfield.icsSpyStatusRemoteFrame
End With
lResult = icsneoTxMessages(m_hObject, stMessagesTx, NETID_HSCAN, 1)

C# Example

Determining if we there's an error in the message (This is indicated by SPY_STATUS_GLOBAL_ERR bit set)

if (mMsg.StatusBitField & SPY_STATUS_GLOBAL_ERR)
{
  // This message has an error in it
}
