Constants

Uninstall drivers and helper DLLs from previous component versions (e.g., 2017). NOTE: This functionality is only available in Windows. This flag does not remove the old PnP driver (VPnpBus) from the system because that driver is not versioned. Use the installer DLL of the old version and its Uninstall() function if you need to uninstall the PnP driver.

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 itself) set it previously.

NOTE: This functionality is only available in Windows.

Install files when their version is the same as the version of already installed files. If this flag is not set (default), the installation logic will overwrite the existing file only if the version number of the file being installed is larger than the version of the file being overwritten. Setting this flag causes the installation logic to overwrite the file even when it has the same version.

NOTE: This functionality is only available in Windows.

Whether the driver should require the controller process to have elevated or system privileges. If this flag is set, the driver will verify that the controller process is a system service or is running with elevated privileges anytime a rule-related operation is performed. If the controller process does not meet these requirements, the operation will be denied.

After installation, the effects of this flag can be changed using the ForceAppPermissionCheck configuration setting.

The packet is dropped (discarded).

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.

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

The packet should be dropped (discarded).

The packet should be sent further.

The packet has been modified and the modified variant should be sent. The Buffer parameter of the Packet event contains modified data that should be sent instead of the original packet.
