Constants

All constants are accessible through the callback.PCAPFilter.Constants class.

Install Flags

INSTALL_REMOVE_OLD_VERSIONS

Value: 0x00000001

Uninstall drivers from previous component versions (e.g., 2022).

INSTALL_KEEP_START_TYPE

Value: 0x00000002

Keep the driver's current start type setting in the registry. If this flag is not set (default), the installation logic will reset the driver's start type setting in the Windows registry to the default value. Setting this flag causes the installation logic to preserve the current value, which may be necessary if the user (or the application) set it previously.

INSTALL_OVERWRITE_SAME_VERSION

Value: 0x00000004

Install the driver file when its version and build number is the same as the version of the already installed driver.

Packet Actions

PACKET_ACTION_DROP

Value: 0x01

The packet is dropped (discarded).

PACKET_ACTION_CAPTURE

Value: 0x02

The packet is captured with the possibility to modify it in the event handler. The Packet event is fired for captured packets with an option to modify the packet contents and send the modified packet.

PACKET_ACTION_NOTIFY

Value: 0x03

The driver asynchronously notifies about the packet, not taking any specific action in regard to it. The NotifyPacket event is fired for captured packets.

Packet directions

PACKET_DIRECTION_ANY

Value: 0x00

All packets are processed.

PACKET_DIRECTION_INCOMING

Value: 0x01

Incoming packets are processed.

PACKET_DIRECTION_OUTGOING

Value: 0x02

Outgoing packets are processed.

Operation modes

PCAP_MODE_CAPT

Value: 0x00

Capture mode. Individual packets are reported through the Packet event as they are received from the network driver. Only packets that match the filter criteria specified in Filter and Direction will trigger the event.

PCAP_MODE_STAT

Value: 0x01

Statistical mode. The component does not report individual packets. Instead, it will collect packet statistics and provide aggregated packet data via the Statistics event.
