Question

I need to stop publishing of a page when a certain condition exists, for example if the page name contains ‘one’ using the Event System. Also, the other pages should continue to publish.

I am thinking to use a PublisherException instead of a generic exception.

The problem is the I do not know the resourceName of the LocalizableMessage. Any ideas?

if (item.Title.ToString().Contains("one"))
{
     Localization.LocalizableMessage errResource = new Localization.LocalizableMessage("error");
     throw new PublisherException(errResource, new Exception("Can't get there from here!"));
}

The Event System can stop Publishing, there is no middle ground there though, when you throw an exception, it stops the entire transaction.

Like Puntero mentions, if you want to remove an item from a Publish Transaction, that is where a Custom Resolver comes in. From here you cannot communicate back to the Publish Transaction, but you have access to the Tridion Logger (eventlog):

Tridion.Logging.Logger.Write("your message string", "MyResolver", LoggingCategory.General, TraceEventType.Information);

With regards to your LocalizableMessage in the Event System, you should be able to do the following:

throw new PublisherException(new LocalizableMessage(Properties.Resources.ResourceManager, "PagePublishErrorMessage"));

Where the resourceName is pointing to the name of a String resource you have in your Project.
