• Add a Tabbed Pane component to your SwingAndTweet application, so you can show your own timeline on one tab and your friends’ timeline on another tab.
• Use a JScrollPane component to add vertical and horizontal scrollbars to your friends’ timeline list.
• Use the getFriendsTimeline() method from the Twitter4J API to get the 20 most recent tweets from your friends’ timeline.
• Apply font styles to your JLabel components via the Font class
• Add a black border to separate each individual tweet by using the BorderFactory and Color classes.
• Add the date and time of creation of each individual tweet by using the getCreatedAt() method from the twitter4j.Status interface, along with the Date class.

Installing FrontPage 2002 Server Extensions for IIS 7 on Windows 7 Ultimate

Last Friday I had to configure a Windows 7 Ultimate machine for developing Web applications with Visual Web Developer 2008, SQL Server Express 2008 and IIS 7. I needed the FrontPage 2002 Server Extensions, and found a new version here: http://www.iis.net/downloads/default.aspx?tabid=34&g=6&i=1630

I installed them on a Windows 7 virtual machine created in VirtualBox, and they work perfectly!

Audio problem in Windows 7 virtual machine with VirtualBox 3.1.2 corrected

I recently installed Windows 7 Ultimate edition on a virtual machine created with VirtualBox 3.1.2, and noticed it didn't recognize the audio driver. Then I googled for an answer to my problem, and found on the VirtualBox forum that I had to download the AC97 drivers from http://www.realtek.com.tw/ and install them on the Windows 7 virtual machine. I did that and the problem disappeared! Now I can hear sound on my Windows 7 VM!

Swinging and Tweeting with Java and NetBeans: Part 2

In Swinging and Tweeting with Java and NetBeans: Part 1 of this article series, we saw a simple way to see your last tweet via a Java application called SwingAndTweet using the Twitter4J API.

In this article by Alfonso Romero, we will add some more functionality to our SwingAndTweet Java application.

Here, we will learn how to:

• Create a twitterLogin dialog to take care of the login process
• Add functionality to show your 20 most recent tweets right after logging in
• Add the functionality to update your Twitter status

In this tutorial, we'll develop the simple Java application further to add some more functions. Now that we can connect to our Twitter account via the Twitter4J API, it would be nice to use a login dialog instead of hard-coding our Twitter username and password in the Java application.

But before we start to build our enhanced SwingAndTweet application, let me show you how it will look like once we finish all the exercises in this part of the tutorial:
