This flag indicates that the related condition requires acknowledgment of this event.
Syntax
'Declaration
 
<DefaultValueAttribute(False)>
Public Property AcknowledgeRequired As Boolean
 
'Usage
 
Dim instance As AEEventData
Dim value As Boolean
 
instance.AcknowledgeRequired = value
 
value = instance.AcknowledgeRequired
Remarks

This property is used only for Condition-Related Events (see EventType).

The determination of those events which require acknowledgment is server specific. For example, transition into a LimitAlarm condition would likely require an acknowledgment, while the event notification of the resulting acknowledgment would likely not require an acknowledgment.

This method or property does not throw any exceptions, aside from execution exceptions such as System.Threading.ThreadAbortException or System.OutOfMemoryException.

Requirements

Target Platforms: .NET Framework: Windows 10 (selected versions), Windows 11 (selected versions), Windows Server 2016, Windows Server 2022; .NET: Linux, macOS, Microsoft Windows
