Programmatically Deleting an Instance
I'm trying to just get a basic NS app up and running. While I can get through the samples just fine, it seems there are no samples that programmatically manage Instances/Applications, etc. I've googled around and not found anything either. Essentially it looks to me that everyone uses the IDF/ADF files. The SDK has some very sparse documentation on it, so I've started there and tried to get things working.
I have code to create the instance/application programmatically, but when I want to drop the whole thing and create it again, upon calling instance.Create() I get an exception (actually this is what the innerException says) saying:
Notification Services failed to read the NSVersionInfo table.
I’m following the example in the SDK (doing Disable/UnregisterLocal/Drop). Interestingly when I do the Disable/Unregister/Drop in SQL Management Studio it works fine. It's also interesting to note that when I ignore the exception it comes up once more, but after that the instance and associated databases seem to be created.
Here’s the short version of my code (getFreshInstance()is the entry method):
private void configureInstance(nmo.Instance instance)
{
prototypeApplication = new nmo.Application(instance, applicationName);
AddDeliveryChannels(instance);
configureApp(prototypeApplication);
instance.Applications.Add(prototypeApplication);
}
private void configureApp(nmo.Application app)
{
AddGenerator(app);
AddDistributor(app);
}
private void checkAndDrop(string name)
{
if (notificationServices.Instances.Contains(name))
{
nmo.Instance instance = new nmo.Instance(notificationServices, name);
instance.Refresh();
instance.Disable();
instance.UnregisterLocal();
instance.Drop();
}
}
private nmo.Instance getFreshInstance()
{
nmo.Instance instance = new nmo.Instance(notificationServices, instanceName);
checkAndDrop(instanceName);
configureInstance(instance);
instance.Create();
instance.RegisterLocal();
instance.Enable();
return instance;
}
Anyone know what I'm doing wrong?
