    <p>When you initialize the sysStatus, you set it to SystemStatus.NullStatus, which I assume is a static SystemStatus instance. This assignment updates the sysStatus variable to point to the NullStatus object in memory - it does NOT make a copy of that object. When you set values through the sysStatus variable, it will update the same object pointed to by SystemStatus.NullSTatus, which is a static object shared by all instances. You may want to change this to a struct, or use a new SystemStatus() instead of pointing sysStatus to that static instance.</p> <p>EDIT: Below was my original answer...</p> <p>I suspect the key to your problem is here:</p> <blockquote> <p>The ParseSystemStatus function is called from an event handler that is triggered every time a UDP message is received</p> </blockquote> <p>All 3 of your instances are wired up to listen for the PacketReceived event. When the OnPacketReceived method is called and it triggers the event stored in PacketReceived, that will fire off <em>all</em> of the event handlers which are wired up to listen to it. That means the client_UnsolicitedMessageReceived method will be called individually for each instance of your class.</p> <p>In other words, the way your system is written now, you have 1 UDP server. Every time it receives a packet, it will notify every instance of SuccinctClass that the packet was received. If you want different behavior, you may have to come up with a way to specify which instance you really want to notify, or to detect from within an instance of SuccinctClass whether you really want to act on a particular packet or leave it up to another instance of the class.</p>

    1. COHmmm. Looks like this comes down to my lack of knowledge then. I was under the impression that since each instance had its own UdpServer that when the event fired it would only notify the instance that created it as that instance is a unique object. It appears you are saying that whenever an object calls the method wired to its event handler it calls that method on all current instances of the class?

    2. COI just tried something and adding a logging statement every time a packet is received. When it is received I log that it was received and the instance that received it identified by a string. The log only logged reception for one instance? The log looked like this...<br><br>Packet Received Device1<br>Packet Received Device1<br><br>If it was notifying all instances I should see Device2,Device3, etc. Now I am even more confused.

    3. COYou would be correct, except that it looks like all of your UdpServer instances are listening on the same port (port 3000, from your comment). If that's the case, either they can all be triggered, or the other two listeners may never even bind to the port or listen at all.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
