"Unravel the esoteric delights of the little-used, but enormously useful RBScript class. Create cross-platform methods for scripting your application and turn your end-users into advocates, ace programmers, or small furry animals. Find out how to create plugins for your application without going bald trying to get the REAL Software guys to implement compiled libraries."

I Wish I Knew How To...Begin Programming Visual Studio 2019 C++/CLI and .NET on Windows Desktop will give you the starting code and controls needed to build your desktop program. Examples are shown with Variables, Conditional Statements, Arrays, Function and Subroutines, a long list of Controls, Text Files, and beginning simple Graphics.

This book is an introduction to those programmers who already know another language and are asked to update an existing C++/CLI program. Although the author wouldn't create a new project in C++/CLI, there are a large amount of programs written in this language that require maintenance, updates, and expanding of current projects.

C++/CLI is a slightly different language than pure C++ since the "CLI" portion of the language largely looks after memory management for you.

What is included in this book?

• 10 Chapters with over 300 pages
• More than 55 example projects
• All examples include code that you can open and run
• Uses the latest version of Visual Studio (2019)
• Uses the Community (Free) version of Visual Studio
• This is a great way to learn C++ while minimizing issues with memory

Topics and information about the book can be viewed at scispec.ca under the books section.

[Show More]

This is a classic example of Newton's Law of Cooling which states that the rate of temperature change of an object is proportional to the temperature difference between the object and its surroundings. In other words, as our cup of coffee nears room temperature, its change in temperature slows down. If we are to plot our coffee temperature with respect to time, the resulting plot will not be a straight line.

So how do we create a computer model of the coffee's change in temperature? This article will step by step, lead you through that fascinating problem. And amazingly, in the end, you will understand what was going on. Never look at a cup of coffee the same way again!

However, REALbasic shares these opportunities with older languages, including scripting languages such as Perl and Python. For anyone used to working in those languages, there's still something missing from the REALbasic tool set. You can create a Python script as a simple text file, set the executable bit on it, and then simply invoke it from the command line (or web page, or whatever). There is no compiling and no building; the operating system simply treats the text file like a program and runs it. Why can't you do the same thing in REALbasic?

As it turns out, you can. This article will show you how.

Xojo provides a RAD (Rapid Application Development) environment because it protects the user from the Operating System. Xojo has many helpful functions, and declares add to this existing toolbox.

Tapping into the Operating System directly with Declares opens up almost all of the options available for a program - but you are also out of the protection of the safe IDE (Integrated Development Environment) of Xojo. With the ability to change anything with the program or operating system, improper code also provides the ability of a crash. This is written for intermediate and advanced programmers of Xojo.

All examples have been converted to 32-bit, 64-bit, ANSI, and Unicode versions. This book is Version 3.0 (October 2018).

This book provides many examples that are converted from C++ functions to Xojo. Although there are many Visual Basic examples that can be converted, vb declare example are becoming outdated, have different parameters, or contain misinformation. For these reasons converting from C++ to Xojo is a long-lasting alternative and which this book provides many descriptions, reasons, references, and working examples for Xojo declares. There are 25 chapters and contains over 900 pages with over 140 example programs.

But most modern engines do more than just check and correct words. They recheck an edited word to see if it is still correct. They build a list of user-defined words and save that list to a file for later use. They replace all instances of a suspect word with one that the user provides. They also ignore words that match a certain pattern.

Some engines will also do basic style checks. Style checks, however, are beyond the scope of this article. Nevertheless, we will show how to add two simple checks to the basic engine.

Computers, on the other hand, have no such natural ability. Yet it's quite likely that sooner or later you'll have to program a computer to solve this exact problem, or one very much like it. These path-finding problems turn up in nearly every modern type of computer game, whether it's finding a route through a deadly minefield or simply navigating from one room to another. If computer games aren't your thing, keep reading anyway; it turns out that a great variety of other problems, which seem quite dissimilar on the surface, can be addressed with the very same techniques.

Oh, and please, don't stick compasses in your eyes, ok?

At the REALbasic Developer Conference in Frankfurt at the end of 2008 at least two developers talked to me about how to generate print files. They seemed to think this was something like brewing magic potions in Professor Snapes lessons!

Both developers were surprised to hear that I print several standard letters with my software without experiencing all those problems. But I’ll let it out at the beginning: I am cheating.

Instead of worrying about the complexities of formatting styled text and printing it on different platforms, I build new “print” documents from a pre-formatted template file. That way I don’t care about the structure or design of that file, or have to code my own printing routine. Instead I just care about placing the new content within the existing template file.

That’s easy! Perhaps it’s too basic for an article, but since these developers hadn’t used this approach, perhaps others out there will benefit from the same technique.

OpenGL is one of the few standards for creating a powerful software interface. There is a great deal of reusable code and material on the internet that can be adapted to Xojo.

This book builds a strong foundation on programming graphics. This is an advanced graphics book and it is highly recommended to understand the Xojo programming language first. An intermediate book called I Wish I Knew How to… Program the Canvas Control with Xojo Desktop is a good book to study and understand before learning OpenGL. Examples in this book have been created and tested on Windows 10 and OSX El Capitan operating systems. This book is focused on 32-bit programming. Much of the code works with a timer to provide smooth graphics and animation. Below are a few videos of examples that are included in this book. These examples are currently 32-bit.

Examples include:

• Many primitives (quads, triangles, etc.)
• Fundamentals of colours
• Movement and rotation
• Points
• Starting a graph and chart
• Beginning lighting
• Lots of texturing
• Blender models
• Transparency
• Camera viewing
• An introductory understanding of threads

[Show More]

The focus of this book is to work with topics related to the Canvas Control. All of these examples are created with native Xojo code and does not use any third party programs. The examples have been tested on Windows 10, OS X Mojave 10.14.3, and Ubuntu 18.04 Operating Systems.

By the time you finish the book you will be able to apply skills from these examples to create your own programs!

Examples were tested on Xojo 2018r4. There is an older Canvas book that has legacy code for Xojo 2014r2 that works without the changes in the Xojo Language.

Goals of the newer updated Canvas 2 book:

• Most drawings are drawn in the Paint event with the Graphics property
• Drawing speed has been increased
• Windows calls the paint event with Invalidate(False) to improve speed and prevent erasing the canvas
• Most examples have been converted to double data-types for drawing locations on the canvas
• Faster RGBSurface.Pixel drawing has been updated from the older graphics. Pixel method (deprecated since 2016 r1)
• Added basic sound in the Space Ship Shooter game
• Removed most PBuffer picture properties and replaced with algorithms to draw in the Paint event (some examples required this property to exist)
• Removed GDIPlus from Windows examples
• Added a couple HiDPI/Retina Examples
• Increased resolution of example screen grabs
• Used the more popular TargetWindows instead of TargetWin32 command
• Added PDF bookmarks for easier reference
• Attempts were made to maintain the same output of the original examples from the first Canvas book to the second Canvas book

What is included with the purchase of this book:

Thirteen chapters and over 450 pages of code to build 60 example programs. Create realistic 2D game motion. It also includes example images and the ways to use them in programs. The book is in PDF format with example chapter folders containing Xojo source code and running examples.

As usual, the answer is 'No.' REALbasic's design philosophy is to build the common functionality right into the product, but to provide all the hooks advanced users need to do advanced things. Deforming a mesh falls into the category of advanced things, but as you'll see here, you can do this in REALbasic while still working with standard RB classes and controls.

Many of these algorithms have been used in medical and scientific imaging. Many are also used for forensic and military work. And thanks to products such as Adobe PhotoShop, the consumer public gets to use some of these algorithms on their personal photos.

In this intro article on image processing techniques we will take a quick look at the field of image processing. Then we will study three basic processing algorithms. Next, we will incorporate these algorithms into three Thread subclasses. Then we will try out these subclasses on a standard test image.

The Concept of Readability

Word processors are both a boon and bane to writers. They allow writers to edit a document without retyping the whole thing. They can check a document's spelling and grammar, tasks that are otherwise tedious to do by hand. Some even have built-in dictionaries to help writers decide if they chose the right words.

[Show More]

For many programs, saving data is relatively trivial. Text in an EditField can be saved to a simple text file, or the contents of a listbox can be saved in a tab-delimitated file. Both of these tasks can easily be automated for simple reuse (for instance, it’s not hard to create EditField or Listbox subclasses that know how to save and reload themselves from a file).

But many programs require a slightly more complicated data structure than mere text. Even if the data itself is fairly straightforward, it may be scattered apart in different areas of your program (i.e., some in a Listbox, some in an EditField, some elsewhere), or it may simply be that you have different kinds of data (numbers and text and colors and pictures) and they can’t all be easily stored in a single file.

I had a vague dream: wouldn’t it be great if there was a pre-written routine, a class or module or something, where I could just pass it my data structure and it would auto-magically save and retrieve the entire thing no matter what the structure or what it contained? Just imagine how much easier that would make developing a new program!

Okay, so that’s still a fantasy, and probably will never happen, but I’ve created something that takes me part of the way there. Instead of trying to create something that will save every type of data structure, I’ve settled on my favorite data structure, the dictionary object. Dictionaries are awesome because they can contain almost anything (even other dictionaries). They provide lightening quick access, can be dynamically adjusted, and are nearly as easy to use as arrays.

What I have done is create a system of dictionary extensions and datatype classes that allow the contents of a dictionary object to be saved to/loaded from a disk file. I have unimaginatively called this “SaveDict.”

Yes, we can: with a design pattern called “Template-Method.” It’s helpful, if you have a fixed sequence of “something” but a lot of variations in that “something.” Is it complicated to make or difficult to understand? Does it need sophisticated mechanics? No, it’s just the good and straightforward use of the good old mechanism called inheritance.

This new book is called I Wish I Knew How To…Use MemoryBlocks with Xojo. The book provides working examples to modify memory, work with structures, and work with binary files. Eugene goes through Bitwise Operations, classic and new framework reading and writing of memory blocks, adding, editing, and removing data, and binary streams.

MemoryBlocks are difficult to master, and provide added speed and flexibility to your programs. Because this is a more challenging topic, there are few resources that are written and even less examples are available. This book provides information and examples on how to work through each solution whether you are a beginning or advanced Xojo programmer.

• Introduces memoryblock addresses and data theory
• Learn about data assignment and retrieval
• Techniques available for text encoding and decoding
• Code for Windows, OSX and Linux OS’s
• Understand solutions with strings and text
• Create, save, and read binary mixed data type binary data files
• Examples include both Classic MemoryBlock and New Framework MemoryBlock data types
• And more…

There are more than 180 pages with over 55 example programs that encompass 10 Chapters. These examples were written and tested with Xojo 2017 r2.

This ebook is a PDF document and all examples include Xojo code. It is presumed that you have an intermediate understanding of the Xojo programming language.

The MemoryBlock Table of Contents is available on the authors website at http://scispec.ca and click in the books header to search for the book. The table of contents has a listing of all the examples in the books, and many terms, and commands used with MemoryBlocks.

Vector graphics are ideal for things like block diagrams, charts, and graphs - anywhere you need graphics composed mainly of simple elements with nice clean lines. However, you may also use the vector graphics classes just to get a little more power for your traditional drawing. For example, if you need to draw a rotated string or picture, then vector graphics are the only way to do it in native RB.

The vector graphics classes may seem a little harder than the traditional Graphics methods at first, but the design is consistent and elegant. Once you get the hang of it, you may find you prefer to use them for all your 2D drawing needs.
