» Object Oriented Programming (OOP) - The Basics
Published 07/15/2009 | .NET Newbie Visual Studio 2008 | Rating:

This is the first article in a series that will cover the very basics of OOP.  It is based on a course I used to run.   When I first wrote this I wanted to create something that I would have found useful in my very early VB.NET days.  A really from-the-bottom explanation that assumed I knew nothing about OOP which would walk me through the basics.

   I hope I have managed to achieve this in this series.

Part 1 covers Properties and Fields

» How To Use The Visual State Manager(VSM) In Silverlight 2
Published 06/26/2009 | Visual Studio 2008 | Rating:

This article walks you through the steps involved in using The Visual State Manager in Silverlight 2.

Most articles seem to use the button as the demonstration element - probably because that makes things very easy.  But as soon as you move away from the small core set of elements such as button that have States preset for you, you will find that you need a slightly different approach.

In this article, I will cover both situations.

» Windows Presentation Foundation: Flow Documents (Part 2)
Published 09/15/2008 | Windows Presentation Foundation | Rating:

  In Part 1, you saw how easy it is to populate a WPF RichTextBox with a XAML FlowDocument.  If you've ever previously struggled with trying to force a RichTextBox to accept an image - and place it exactly where you want it - in Windows Forms, then you'll welcome this new tool.

 However, for legacy reasons you might want to populate the RichTextBox with content that has been saved in RTF format.  In this part we will look at how that can be achieved.

» WinForms and WPF Interop - The Best of Both Worlds

  Whenever I see a question along the lines of "How can I include an image alongside each item in a list of items or use more than one font, or varying background colors?" I usually find myself muttering "WPF!".    This is a lot more sociable and positive than many of the things I mutter as I sit here each day, but finally I've realised that I need to do something about it.

  The result is this article, which works through the steps needed to harness the rich UI features of WPF to the more familiar paradigm of Windows Forms.

   The example used will show you how easy it can be to use a WPF control in a Windows Forms application and you can use this article as the stepping stone to creating your own.  The ListBox layout shown below will be created in WPF and ported over to be used in a Windows Forms application.

» Multithreading The Easy Way: The BackgroundWorker

  Sometimes you may need  your application to work on a slow or time- consuming task in such a way that your user isn't kept waiting unnecessarily while this is happening.

   The answer to this problem is to use multithreading.   Having seen many forum questions about multithreading, I know that many people are a bit apprehensive about tackling it.  However,  as it turns out, the BackgroundWorker component is versatile  and easy to use, providing a painless solution to this requirement. 

   In this article I will show you how you can  incorporate the BackgroundWorker into your projects to give your users a more professional and less frustrating experience.

» Windows Presentation Foundation: FlowDocuments (Part 1)
When WPF first came on the scene, one of the features that got a lot of air time was the display of documents.  Leading edge projects like the NY Times Reader and the British Library manuscript display raised a lot of awareness of the possibilities.  Strangely though, since VS 2008 shipped there doesn't seem to have been a lot of mention of this part of the package.  So I thought I'd take a look at how easy (or not) document handling really is in WPF.

» OOP: Create, Collect, Sort, Save and Retrieve Objects
Published 03/18/2007 | .NET Newbie Visual Studio 2005 Visual Basic 2005 | Rating:

  Several recent posts in the VBCity Forums made me realise that it might be useful to have an article that dealt with some of the basic requirements when it comes to creating your own classes and objects.  

   Many beginners start by creating a simple game and this is often a good learning project so we will use this approach in this article.  Two key elements of a game application like this will probably be a way of creating Players and keeping a record of their High Scores . Users can log in to the game using their Player name and see their last score.

   As they play again in this session they might increase this score or start over from zero. They might even want to see how their score rates against other Players.    So we would need a way of creating a collection of Players and their Scores.  And as we usually want to see the Scores listed from highest to lowest, there will have to be a way to sort those Score values that are stored in the collection.

   Finally, it wouldn't be much use if the Scores were all lost each time the application ends, so we should also build in a way of saving the latest data to the hard drive and of course a means of retrieving  them when you need them.

   This article for beginners uses VB 2005 and shows you how to meet all these requirements.

» Professional Visual Studio 2005
Published 11/19/2006 | Book Reviews | Rating:


  The average VB.NET developers' book starts  with the language and uses the IDE to help along the way.  This  book takes a different approach.  It starts with the IDE and radiates out from there.  (IDE-centric I think they  call it in the publisher's blurb).   It's an interesting approach, but does it work?

Ged Mead decided to find out.

» Application Settings in VB 2005
Published 11/09/2006 | .NET Newbie Visual Basic 2005 Win Forms | Rating:

   There may be times when you would like to give your users the opportunity to save various settings (and they would probably appreciate having the facility too!).   In the past, the SaveSettings and GetSettings methods were the usual avenue, but in VB 2005 you have some more flexible choices at your disposal.

  Ged Mead looks at these new tools.

  Matthew MacDonald is a well-known and respected technical book author.    I already own and regularly use several of his previous .NET books, so when this one came out I was particularly interested to see if it came up to his usual high standard.

 

  Overall, I was impressed with the detail and clarity of this book which was firmly targeted at Classic VB developers who are ready to move on to .NET now that the promised improvements in VB2005 are finally here.

» Book Review- "Visual Basic 2005 Express: Now Playing"
Published 05/14/2006 | .NET Newbie Book Reviews | Rating:

 If you are a complete newcomer to programming, you should seriously consider getting a copy of this book.  It never loses sight of the fact that beginners don’t always “get it” first time, every time and it uses non-technical explanations and good learning reinforcement techniques to show you the skills in the easiest, least complicated way possible.

    In the Preface to the book, author Wallace Wang sets out his philosophy:

“This book is dedicated to everyone who didn’t have the “right” education, test scores or job skills, but wound up succeeding at their chosen goal anyway.   If you want to learn or do anything in your life, such as learn to program a computer, go ahead and do it and don’t let anyone ever tell you otherwise.”

» Chart Success : GDI+ Graphics At Work Part 4
Published 05/10/2005 | .NET Framework Graphics | Rating:

 Back in Part 2 of this series we created a basic Bar Chart.  It did the job, but - let’s face it - it isn’t likely to win any prizes in the “GUI of the Year “ competition.

  So, in this article we will use the same basic approach, but will build a better  3D bar chart to give the display more depth, color and hopefully, as a result, more impact.

» Chart Success: Second Helpings of Pie. Part 3
Published 03/23/2005 | .NET Newbie Graphics | Rating:

The first two articles in this series introduced some basic graphics skills which were used to create a Pie Chart in Part 1 and a Bar Chart in Part 2. Both charts were elementary, but served their purpose. As the series progresses we will look at ways of building on these early steps and creating more challenging displays. In both of those articles the data was created in advance at design time and hard coded  into the project. In this article,  data will be taken from the user and used to create a pie chart. This project also introduces HatchStyles - a range of predefined patterns - to replace the solid colors used in the first Pie Chart example.

Charts are a great way of displaying data in a format that is easy to understand. A chart is a pictorial representation of your data. If it is true that a picture is really worth a thousand words, then a chart must surely be worth a thousand lines in a DataGrid. In this series of articles, we will look at various ways you can use the GDI+ tools in .NET to create a range of charts for a wide variety of uses. In Part 1, we will look at one of the easier options, the Pie Chart.
