Hi

I am interested to Listen to events from the server.
I am able to read tag values using the EasyDAClient So I know that the OPC server is running fine and the connection between the client and the server is fine

I am interested to learn to Handle events that are triggered by the server. So I have tried doing this.


OpcLabs.EasyOpc.AlarmsAndEvents.EasyAEClient client = new OpcLabs.EasyOpc.AlarmsAndEvents.EasyAEClient();
client.SubscribeEvents("W7VM", "OPC.Siemens.XML.1", 1, (sender, evnentArgs) =>
{
MessageBox.Show(eventArgs.ToString());
});

But I keep getting the error stating that "{[12585994] *** System.InvalidCastException: No such interface supported };" Which means that the call back function is triggering but there is something that I am missing.

FYI.. I have Configured an Alarm in the WinCC server

Can someone please teach me as to how I can use the EasyAEClient to handle events that are triggered by the server.
