When an error occurs in DAQFactory, an alert is generated.  Alerts appear in the docking window at the bottom of the screen labelled Command / Alert.  This window maintains a list of alerts along with the command line.  

Alerts are programmatically available with history like a channel for use in sequences or expressions. strAlert[0] will retrieve the most recent alert message. strAlert has a 100 entry history.  Note that even though your commands appear in the command/alert window, only alert messages are saved in this history.

Alerts are not automatically logged.  You must specify them in a logging set by hitting Manual and entering Alert.  Alerts are strings so can’t be used in binary mode logging sets.

Alert Preferences:

There are two preferences relating to alerts.  These are available from the preferences window by select File - Preferences from the main menu.

Flash Window on Alert?  If checked, the DAQFactory window will flash whenever an alert arrives.  If not, only the alert area of the status bar will flash.

Show all Alerts in Alert box only: This is identical to the option presented when an alert is displayed and eliminates any alert popups.
