That doesn’t mean you need to hit return and start a new line it just means that the margins of a You will sometimes see the ¬ symbol in a code example. Most of the code examples in this book are accompanied by a series of steps explaining how things work. It will probably provide more details about the task you’re working on. This is a more detailed explanation of the step above. If that happens, type what’s inside the quotation marks, but not the quotation marks themselves. 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) Meant to be typed into Xojo exactly as it appears on the page.
theMessage = theMessage + myString + EndOfLineĪs you read this book, you also will notice different formats of text.Īnother format you will see is steps. You should type it in all on one line, like this: One of the sample apps is web-based, so you’ll see that its TheMessage = theMessage + myString ¬ ! + EndOfLineĪpps for different operating systems, some of the screenshots in this book were taken on Windows and some were taken on OS X. So if you see code like this:īecause Xojo can run on different operating systems and build See the ¬ symbol, don’t type it in just keep typing what’s indented on the next line. Special thanks go out to Brad Rhine who wrote the original versions of this book with help from Geoff Perlman (CEO of Xojo, Inc). Once you’ve learned one language, though, the others become much easier, because ii 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. (unless you already were when you started!), but you should haveĪ solid grasp on the basic building blocks of writing your own apps. This makes it very easy to start writing your own apps When you finish this book, you won’t be an expert developerĬomputers. 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 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. You’ve already learned the basic concepts involved.
