This series explores the various gadget objects and how they can be used enhance the functionality of your gadget. They're grouped based on their functionalities:
  • Contacts
  • Debugging and diagnostics
  • Sidebar gadgets UI
  • Machine information
  • Emails
  • Network
  • Sounds
  • Time and time zones
Part 1 covered the first four functionalities, and Part 2 will cover the last four.

Emails
Using Sidebar, you can access the email content of your Windows Mail (formerly known as Outlook Express) account using the following gadget objects:

  • System.MessageStore
  • System.MessageStoreFolder
  • System.MessageStoreMessage
System.MessageStore
The System.MessageStore object returns a collection of System.MessageStoreFolders objects. The following code prints out the various folders in Windows Mail (default email account):

var result = document.getElementById("result"); //---get all the different folders in the mailbox--- var folders = System.MessageStore.Folders; for (i=0; i<folders.count; i++) { var folder = folders.item(i); result.innerHTML += "Name: " + folder.name + "<br/>"; }

Here's an example of the output:


Name: Inbox Name: Outbox Name: Sent Items Name: Deleted Items Name: Drafts Name: Junk E-mail

Add the following code and you can print out the total number of messages contained within the folders—in addition to printing the folder names:

result.innerHTML += "Name: " + folder.name + "<br/>"; result.innerHTML += "Unread Messages: " + folder.unreadMessageCount + "<br/>"; result.innerHTML += "Messages: " + folder.messageCount + "<br/>";

System.MessageStoreFolder and System.MessageStoreMessage
The System.MessageStoreFolder object returns a collection of System.MessageStoreMessage objects.

The code in Listing 1 prints out the content of all the messages contained in each folder.
