![]() ![]() ![]() You might be asked to set “Some Text” as something’s caption. A code example looks like this: Dim x As Integer Dim y As Integer Dim z As Integer x = 23 y = 45 z = y * x MsgBox Str(z) This is something you’re supposed to do. Anything in a code example is 1) meant to be typed into Xojo exactly as it appears on the page. A step looks like this: One format is code examples. theMessage = theMessage + myString + EndOfLine As you read this book, you also will notice different formats of text. One of the sample apps is web-based, so you’ll see that its You should type it in all on one line, like this: screenshots were taken in a web browser. So if you see code like this: Because Xojo can run on different operating systems and build theMessage = theMessage + myString ¬ ! + EndOfLine apps for different operating systems, some of the screenshots in this book were taken on Windows and some were taken on OS X. iii Conventions see the ¬ symbol, don’t type it in just keep typing what’s indented on the next line. Once you’ve learned one language, though, the others become much easier, because ii Acknowledgements Special thanks go out to Brad Rhine who wrote the original versions of this book with help from Geoff Perlman (CEO of Xojo, Inc). That’s why this book focuses on Xojo - because it’s easier to learn than many other languages. The hardest programming language to learn is the first one you learn. My hope is that reading Introduction to Programming with Xojo, you’ll be motivated to learn more about Xojo or any other programming language. a solid grasp on the basic building blocks of writing your own apps. This makes it very easy to start writing your own apps (unless you already were when you started!), but you should have without a big investment up front. Xojo is free to download, install, and run - you only need to pay if you need to compile your apps so that they can run on other people’s When you finish this book, you won’t be an expert developer computers. To do so, simply visit and click on the download link. Before you get started, you’ll probably need to download and install Xojo to your computer. Where possible, some commonalities and differences are pointed out in notes. So while this book does focus on Xojo, the concepts that are introduced are applicable to many different programming languages. After all, a loop is a loop in any language. For example, once you know to write code in Xojo, learning Java becomes much easier, not only because the languages are similar, but because you already know about arrays, loops, variables, classes, debugging, and more. Copyright & License Foreword you’ve already learned the basic concepts involved. ![]()
