Take the red pill, get the blue screen!

ha ha.. nice humor.

1. The Identity Selector dialog box is displayed only for SSL protected pages. Therefore you are required to deploy your application on a Web server and install a SSL Certificate.
2. Windows CardSpace does not work with Self Signed Certificates and will die horribly. These certificates do not have CRL field. It contains a URL that CardSpace will check for the revocation list.
3. For ASP.NET developers there is Toolbox control written by Christian Arnold. Add this to your Toolbox and you won’t need to write a single line of code. Watch demo.
4. When you use CardSpaceLogin controls you must run application over SSL. The application pool also need to be run under Local Systems identify; otherwise w3wp.exe process will not be able to retrieve server’s private key. In such case you may end up with error stating Keyset does not exist. Note: This is not advisory if the application pool is shared with other Web applications. [ Edited: Refer Barry Dorrans comment for more details.]
5. When using Information cards there is nothing like passwords.
6. CardSpaceLogin controls are integrated with your identify providers such as Forms Authentication. For example: If you use Information Card to register a user, his details are reflected in the identify source.

Steps:

1. Open your outlook
2. Press Alt+F11. This open the Visual Basic editor
3. On the Left Pane, one can see “Microsoft Outlook Objects”, expand this. Now one can see the “ThisOutLookSession”.
4. Click on “ThisOutLookSession”.
5. Copy and Paste the following code in the right pane.(Code Pane)
6. Private Sub Application_ItemSend(ByVal Item As Object, Cancel As Boolean)
   Dim strSubject As String
   strSubject = Item.Subject
   If Len(strSubject) = 0 Then
   Prompt$ = “Subject is Empty. Are you sure you want to send the Mail?”
   If MsgBox(Prompt$, vbYesNo + vbQuestion + vbMsgBoxSetForeground, “Check for Subject”) = vbNo Then
   Cancel = True
   End If
   End If
   End Sub
7. Now save and close the VB Code editor. From now on , this macro will make sure you do not make the mistake of sending a mail without subject.
