The OnDigEvent command sets the handle of a window to receive a notification message when a digital
match event is triggered. This function uses the same mechanism as the OnEvent command. For details,
see the description of OnEvent .
Note: This function sets the event generation mechanism to be a window notification message,
replacing any previously defined event notification mechanism. Only one event notification
mechanism can be used at one time.
