The OPC Server Dialog (OpcServerDialog class) allows the user to select the OPC server interactively from the list of OPC “Classic” servers installed on a particular machine.

To select from OPC Alarms&Events servers, you use the same dialog as with OPC Data Access servers – for details on that dialog, see OPC Server Dialog under “User Interface for OPC-DA”. The only difference is that before running the dialog, you need to make sure that its ServerFamilies property is set so that it includes (or only contains) the OpcAlarmsAndEvents enumeration member.
