# Graphical Panel Controls: Message History

This control allows you to review the messages received by Vehicle Spy, essentially embedding a [Messages View](/vspy-3-documentation/vehicle-spy-main-menus/main-menu-spy-networks/messages-view.md) window within a graphical panel. Message filters can be applied within the control so that only messages of interest are shown.

A list of common properties can be found under [Common Control Properties](/vspy-3-documentation/vehicle-spy-main-menus/main-menu-measurement/graphical-panels/graphical-panels-tools/graphical-panel-controls-common-control-properties.md).
