A '''daemon''' is a process that runs in the background, not usually visible to a user. In LabVIEW, daemons are usually implemented as one of two types: self-launched or launched.

==Self-launching daemon==
A ''self-launching daemon'' is a VI that executes, closes its own [[front panel]], and continues to run in the background. A VI normally ceases to execute when its front panel is closed. To avoid this, a daemon VI first opens a [[VI reference]] to itself. The VI can then use the Front Panel:Open method to set the state of the VI to "hidden." In LabVIEW versions earlier than 8.0, the Front Panel:Open method is not available, but the Front Panel Window:Open property can be used.
