Syntax

Sub ipmonitorcontrol_IPPacket(SourceAddress As String, SourcePort As Long, DestinationAddress As String, DestinationPort As Long, IPVersion As Integer, TOS As Integer, Id As Long, Flags As Integer, Offset As Integer, TTL As Integer, Checksum As Long, IPProtocol As Integer, Payload As String)

Remarks

When Active is True, the control will listen for network traffic. For each packet sent across the interface in LocalHost, the control will parse the packet and fire an IPPacket event with the header fields and payload. The parameters are defined as follows:

SourceAddressThe IP address of the originating host in IP dotted format.
DestinationAddressThe IP address of the destination host in IP dotted format.

OffsetThe fragment offset of this packet in relation to larger data.
TTLThe time to live for this packet.
IPProtocolThe IP protocol used in the payload.
PayloadThe data field of the IP packet. This field may contain extra IP headers, depending upon the IP protocol used to create it.
