Cancel([ActorID])

Executes a Cancel action, in which the ActorID parameter is the user name. If omitted, it assumes Elipse Water Viewer's user logon, "Anonymous" if there is no user logged on, or "System" if that method's call started at the server. If there is a pending Operate or Select action, these actions are canceled and the OnOperateFinished or OnSelectFinished event is immediately triggered, executing the associated script and canceling this occurrence. For this action to occur, some conditions are expected:

•The Unit's parent Command must have its Enabled property set to True

•There must be no Cancel command pending in the Command Unit, that is, the ActionInProgress property must be set to 0 (zero, None), 1 (one, Operate), or 2 (two, Select)

•The OnCancel's event script must be defined in the type of configured command Conversion

This method waits for a feedback value up to the specified limit time if all the following conditions are met:

•The script was successfully executed

•The script was not canceled

•The feedback limit time of the Conversion is not 0 (zero)

•The feedback Tag's path is not empty

If the feedback value is not used by the Tag inside the limit time or the Tag's path is invalid, but it is not empty, this command is considered as failed.
