Ozeki NG SMS Gateway

C# SMS API - onMessageDeliveredToNetwork

This event is invoked by the SMS Gateway when the SMS is accepted by the network for delivery. If you have a slow service provider connection (for example you use a GSM Modem) and you are sending a lot of messages Ozeki NG will put the messages into a message queue called outbox until there is capacity available for sending. As soon as service provider capacity becomes available the message is sent and the onMessageDelivedToNetwork event is invoked

To handle this event, the following delegate type is used:

public delegate void DeliveryEventHandler(string messageID, DateTime deliveryTime);

And the following event is accessed:

public event DeliveryEventHandler onMessageDeliveredToNetwork;

     Name Description
void onMessageDeliveredToNetwork( string messageID, DateTime deliveryTime); Create a function with this header and attach it to the onMessageDelivedToNetwork event to receive notifications about message delivery events.


messageID - The message id that was returned by the SMS Gateway when you have posted the message for sending using the sendMessage method.

deliveryTime - The timestamp that marks the occurence of the event


Step 1. - Create the event handling function:

   void myDeliveredToNetworkHandler(string messageID, DateTime
     console.writeln("The message is delivered");
Step 2. - Attach this event to the SMSClient object:

   mySMSClient.onMessageDeliveredToNetwork += ServerEventSink.wrap(myDeliveredToNetworkHandler);
Hint: Notice the ServerEventSink.wrap method, that is used to attach the event. This wrapper is used to work around an error that can happen when asynchronous callbacks are invoked in .NET remoting.
