How to Attach Notes to TreeView Branches in Delphi

Here's my latest video on programming a collapsible outliner using Delphi. In this one, I associate text notes with the branches (nodes) of a TreeView.

Ruby Instances and Instance Variables

What the heck is an 'instance' and why does it have its own variables? My latest YouTube video for Ruby programmers explains all...

Program a Collapsible Outliner in Delphi with Object Pascal

Collapsible Outliners are fantastically useful things. And they aren’t all that difficult to program. I have a short free course on YouTube that shows you how to create an outliner using the free Delphi Community Edition from Embarcadero and the Object Pascal language.

This free course shows you how to add branches and sub-branches to an outline and even how to drag and drop branches from one place (one ‘node’) to another in the outline ‘tree’. Later in the series I’ll show how to add formatted notes to branches so that you can create a brainstorming tool. This is a fun and useful project and a great way to learn to program in Delphi.

Delphi, incidentally is 25 years old this week. How time flies! I was one of the beta-testers for Delphi 1 and for over ten years I wrote the Delphi programming column for ‘PC Plus’ magazine in the UK. Object Pascal is a really nice language and Delphi is an excellent Windows-based IDE.

Incidentally, even if you aren’t interested in Delphi, bear in mind that I have lots more free programming lessons on YouTube. At the moment, I’m releasing one new video every week on topics ranging from Ruby programming to writing an adventure game in Java.

These free courses can all be found in my playlists here: https://www.youtube.com/user/BitwiseCourses/playlists

Learn To Program C, Pointers and Recursion

I’m pleased to announce that Bitwise Courses is now partnered with Bitwise Books! We’ve been working away at this for most of the last year. Our aim is to publish a range of tightly-focused programming books that explain just what you really need to know without any padding.

The series is called The Little Book Of… and our first three titles are:

The Little Book Of C Programming
Amazon.com
Amazon.co.uk

The Little Book Of Pointers
Amazon.com
Amazon.co.uk

The Little Book Of Recursion
Amazon.com
Amazon.co.uk

In addition, we have created a series of free programming guides called A Really Simple Guide To… These include A Really Simple Guide To Object Orientation, C IDEs and Pointers. To can get the guides delivered straight to your inbox (no purchase necessary) from the Bitwise Books site.

We’ll be announcing more Really Simple Guides and Little Books Of (various programming topics) soon.

Constructors in C#

Before you can use an object you have to create it. That is what this video from my C# course explains...



My course ‘Learn C# Programming (in ten easy steps)’ was first created in 2012 but now, in 2017, it has been completely remade. Every single video has been re-done and no less than 86 new video lessons have been added. What’s more, students can also download the entire version 1 of the course (almost 4 more hours of video) as an added bonus. This is what the course contains:

• 117 video lessons
• 7 hours, 7 minutes of video
• 32 sample projects
• 10 quizzes
• 89-pages of pdf documentation
• PLUS: The entire version 1 course as a free download!

The regular price for this course is $145. But use the link below to sign up for just $35 (valid only until the end of 2017, so don’t wait!)

Pointers and arrays in C

This is an extract from my advanced c course on pointers...

Pointers for C Programming - new course

Get this $95 course for just $15.

Pointers. In C, there is just no getting away from them. Understanding and being able to use pointers correctly (and safely) – well, it’s the difference between a professional programmer and an amateur. But pointers are really difficult to use. Aren’t they?

The fact of the matter is, they needn’t be. If you understand them. And that’s what my new course is all about. “Advanced C Programming: Pointers” explains pointers from the ground up. What exactly is a pointer variable and how does it work with addresses in memory? What is indirection? How can you avoid common pointer problems such as memory leaks and program crashes?

Topics covered include:

• Pointers and addresses
• Indirection and multiple indirection
• Pointers and arrays
• Pointers to structs
• Data-type alignment
• Generic pointers and casts
• Null pointers
• Memory allocation and reallocation
• Freeing memory safely
• Pointer arithmetic
• Singly and doubly linked lists
• Queues and stacks
• Pushing and popping
• Function pointers
• Deep and shallow copying
• Common pointer errors

…and much more

NOTE: This is not a course for beginners. It is aimed at programmers who already have a good working knowledge of C programming and who need to take the next step in mastering C by gaining a deep understanding of pointers. (If you are a beginner, you should sign up to my C Beginners Course first).

Course contents:

• 58 Lectures
• Over 3.5 hours of video instruction
• Downloadable source code of all examples
• Quizzes and course notes
• Lifetime access
