Subscriber.Enabled() returning incorrect result

Hi Pinal -

This code snippet demonstrates how to use the SubscriberEnumeration object to retrieve a subscriber object and view its Enabled property in a Label.

private void button1_Click(object sender, System.EventArgs e)
{
//the subscriber id we will work with
string subId = "joew@webbtechsolutions.com";

//Create an NSInstance object
string instanceName = "myNotifyInstance";
NSInstance instance;
instance = new NSInstance(instanceName);

//create disable an existing subscriber
Subscriber subscriber =new Subscriber(instance);
subscriber.SubscriberId = subId;
subscriber.Enabled = false;
subscriber.Update();

//create a new subscriber object
Subscriber subscriber2 = new Subscriber(instance);

//set the subscriberId
subscriber2.SubscriberId = subId;

//Create a SubscriberEnumeration object
SubscriberEnumeration subscribers = new
SubscriberEnumeration(instance);

//retrieve the subscriber object
subscriber2 = subscribers[subId];

//check the enabled property
label1.Text = subscriber2.Enabled.ToString();

}

HTH....

Hi Shyam -

I think that the following code snippet (v2.0) may reproduce what Pinal was experiencing.
If so, the main issue seems to be in the GetSubscriptions method. Intuitively, one may be likely to think that calling the function would populate the subscriber object - including the Enabled value, however in this case it doesn't seem to do that, leaving the default value of true in place. (I could not find anywhere in BOL that said that it would.)
private void button1_Click(object sender, System.EventArgs e)

{

//the subscriber id we will work with
string subId = "joe@webbtechsolutions.com";

//Create an NSInstance object
string instanceName = "myNotify";
NSInstance instance;

instance = new NSInstance(instanceName);

//create disable an existing subscriber
Subscriber subscriber =new Subscriber(instance);
subscriber.SubscriberId = subId;
subscriber.Enabled = false;
subscriber.Update();

//create a new subscriber object
Subscriber subscriber2 = new Subscriber(instance);

//set the subscriberId
subscriber2.SubscriberId = subId;

//use the GetSubscriptions to retrieve the subscriber object
SubscriptionEnumeration subscriptions = subscriber2.GetSubscriptions(new NSApplication(instance, "myApp"), "mySubscription");

//check the enabled property
label1.Text = subscriber2.Enabled.ToString();

}

OK, I see the problem. You are creating a new subscriber object to represent the existing subscriber, but nowhere is that object being initialized from the database. The GetSubscriptions object does not initialize the subscriber object.

Instead of creating a new objects, you should retrieve a subscriber object for the existing subscriber from the SubscriberEnumeration. This will obtain the correct values from the database.

The code would look something like this (it may be a little off because I'm typing this from memory - I'm not at a setup where I can test this right now):

SubscriberEnumeration subscribers = new SubscriberEnumeration(nsInstance);
Subscriber existingSubscriber = subscribers["exstingSubscriberId"];

if there is no existing subscriber with the id you pass to the indexer ("existingSubscriberId", in my example), the call will throw an IndexOutOfRangeException.

Hope this helps.
