Thanks for quick reply.

Hello.

EasyAENotificationEventArgs has an Event property, of type AEEvent. This object contains members like Message, Severity etc.

Note that first notifications (and some others) you receive after a subscription is made are special ones, and may contain a null Event. More information is e.g. here:

Hello
I used easyAEClient to get alarms from server.Everything is working.I got alams.
BUT !!! in client_Notification event I cannot get event info at all. Your NotificationEventsArg structure does not contains any event information like message ,severity etc.

How to get this info ?????
thanks

Hello,
Thank you for your interest in our products.

Let me get some clarification first:

Are you interested in
1) obtaining alarms that originate *in the OPC Server (or the underlying process)*, and are delivered using OPC Alarms & Events specification, or
2) using OPC Data Access specification, and getting information such as "connection to OPC Server broken", "connection reestablished" etc.? If so, do you plan to invoke "reads" explicitly from your app code, or would you rather "subscribe" for significant changes, and have them delivered as necessary, via callbacks?
3) both?

Best regards,

Hello
I downloaded your trial version for NET. Works fine under NET 4.0 and in VS 2010.

Major question: your codes are done for data reading from server. BUT how I can get alarms,generated by server or other events(like loading,connection,timeout etc.) This event handling is the most important for my application.Use C#.
Any ideas ???
Thanks
