CHAPTER 1 AN INTRODUCTION TO REALBASIC At press time, REALbasic 2006 Standard Edition for Linux was free. In addition, you could purchase a license key for the Macintosh or Windows version of REALbasic Standard Edition for $99.95. The purchase price for any of the three Professional Editions of REALbasic is $499.95. Once installed, you can activate either the Standard or the Professional Edition of REALbasic by entering the software key you obtained from www.realsoftware.com. In other words, if you enter a key for the Standard Edition, REALbasic Standard Edition will run. However, if you enter a key for the Professional Edition, the REALbasic Professional Edition will run. Note If you don t get your software key before you install REALbasic on your computer, REALbasic prompts you to do so the first time you start it up. REALbasic vs. Visual Basic When it comes to the development of Windows applications, REALbasic s main competitor is Microsoft s Visual Basic programming language. If you are a Windows programmer with a background in Visual Basic, you are going to find that REALbasic is remarkably similar to Visual Basic. As a result, you can get up and running quickly and can leverage nearly all your Visual Basic programming experience. This is especially true for Visual Basic programmers with a Visual Basic 6 background. The reason is because REALbasic closely mirrors much of what is in Visual Basic 6. Programmers with a background based on Visual Basic .NET also find the transition to REALbasic relatively smooth and can bring over most of their Visual Basic programming experience, less any .NET-specific features. Because REALbasic is so similar to Visual Basic, you ll find it is relatively easy to port your Visual Basic applications over to REALbasic. In fact, you ll probably find you can port your applications over in an hour or a day, instead of weeks or months, as would be the case if you moved from Visual Basic over to another programming language, such as C++ or Java. REALbasic and Visual Basic are similar to one another, but plenty of important differences exist. These similarities and differences are highlighted in the following sections. The Development Environment Both REALbasic s and Visual Basic s IDE are similar and their development process is nearly identical. You start by adding controls to a window (called a Form in Visual Basic). Then, you set window and control properties, and add code. Next, you test your application and, when you are ready, you compile your stand-alone application.
