Setting an alert in WebProvisioned event

Question

I want to set alerts for all users whenever a new subsite is created under the root site.

I am using the WebProvisioned event, but when I attempt to Update() my new alert I get an error: "There is no web named ". "A first chance exception of type 'System.IO.FileNotFoundException' occurred in Microsoft.SharePoint.dll"

Any help appreciated, thanks.

My code is below:

public override void WebProvisioned(SPWebEventProperties properties)
   {
       base.WebProvisioned(properties);
       if (properties.Web.ParentWeb.Name == "emerg")
       {
           SPSite site = new SPSite(properties.Web.Url);
           SPWeb web = site.OpenWeb(properties.Web.Url);

           SPAlert newAlert = web.Alerts.Add();
           newAlert.AlertFrequency = SPAlertFrequency.Immediate;
           newAlert.AlertType = SPAlertType.List;
           newAlert.EventType = SPEventType.All;
           newAlert.Title = "all alerts - " + properties.Web.Name;
           newAlert.Update(false); //errors here
       }
   }

Answer 1

1. try adding Synchronous in the Elements.xml to ensure operations do not run in separated threads.
2. Make sure you check for the properties.Web!=null to make sure you actually get the site successfully created.
3. No need to use SPWeb web= site.OpenWeb again, rather use directly properties.Web. Besides do use Disposable pattern when instiantiating new SPWeb, e.g. put in a using {}.
