With Yukon on the horizon, I'm thinking about the "unmanaged Yukon equivalent" we have now - Extended Stored Procedures.  I've used them in the past for such cleverness as calling out to Ws Services from within SQL Server and calling back to other boxes in an asychronous Observer-Observable pattern to let folks know about Data Changing for cache clearing events.

Now, no doubt Yukon will be much more robust even hosting in-proc componentry via Application Domains or out of proc via an ASP_WP style worker process, but until then, are Extended Stored Procedures (in VB6 and C++) evil? See http://tinyurl.com/4er4 (Google Groups Post)

Requirement:

Pre-Load the ASP.NET Application object and don’t allow other pages in your project to add/modify/delete. Basically, make Application read-only.

Solution:

         private void SetApplicationReadOnlyStatus( bool state ) {
                  Type type = Application.GetType().BaseType;
                  PropertyInfo readPropInfo = type.GetProperty("IsReadOnly",  BindingFlags.NonPublic | BindingFlags.Instance) ;
                  if( readPropInfo != null ) {
                        readPropInfo.SetValue( Application,Convert.ChangeType(state,readPropInfo.PropertyType ) ,null);
                  }
            }
            private void Page_Load(object sender, System.EventArgs e) {
                  Application["MyKey"] = "myValue";
                  // Set application to readonly so that we will not allow any changes.
                  SetApplicationReadOnlyStatus( true );
                  try
                  {
                        // Try setting a value 
                        Application["MyKey"] = "New value";
                        Response.Write("You won't see this");
                  }
                  catch(Exception ex) {
                        // You'll end up here
                        Response.Write(ex.Message);
                }
            }

Thanks to Sairama for the code!

Paul Allen's Vulcan Mini-PC. Here is another interesting device from CES this week. "A hitherto unknown group within multibillionaire Paul Allen's Vulcan Inc. techno-empire has designed a compact, lightweight, wireless computer that is expected to debut by Christmas for between $1,200 and $1,500." It runs Windows XP. Now this is a device I would want. I have never seen the interest in the OQO. Too big to be a PDA, to small to be a work machine. The Vulcan though is the ultimate mini-PC.

Specs include:

• 5.8-inch screen at 800X400
• 20GB drive
• Support for external keyboard and mouse
• Batteries last for up to four hours
• USB 2 port with external CD-ROM
• WiFi or one of two cellular technologies integrated at the choice of the OEM.
