Implementing Edit and Format Features in a WPF RichTextBox

by Ged Mead via XTab (Ged Mead) on 3/8/2010 7:35:00 AM

In previous blogs, I looked at how to access a plain text file through a RichTextBox and then how to open and save content in RTF format . In the second blog, I also looked at some core editing features which are available as keyboard shortcuts. This time I want to look at how to create a simple text editor based around the RichTextBox. I also want to cover the scenario where you load a file of one type, such as a plain text file, make changes and then save it as an ... [ read more ]

Programmatically changing radio buttons

by LarryBlake via VB & .NET Blogs @ vbCity.com on 3/3/2010 9:15:00 PM

You might think that a set of radio buttons behaves like a single control, and can be used interchangeably with a single-select ComboBox. Often it can, however there is a slight difference that can trip you up. If you add a "CheckedChanged" event to all the buttons (or a single one that handles them all), you will find that the event code fires twice. Checking a new button fires the change event for the new button, because it is now checked. It also fires ... [ read more ]

WPF RichTextBox: How To Load, Edit and Save Rich Text Format

by Ged Mead via XTab (Ged Mead) on 3/1/2010 4:05:00 PM

In an earlier blog , I looked at how to load and save plain text between a RichTextBox and a txt file. This time I want to look at a different case where text formatting has been applied to the content. For the purposes of this sample I’m going to take a document that has been created in MS Word. One of the many formats that both MS Word and WordPad support is RTF. You can view and edit the RTF document in the RichTextBox. The WPF Window ... [ read more ]

Visual Basics - Banker's Rounding

by Mike McIntyre via Mike McIntyre on 2/28/2010 4:48:00 PM

When you add rounded values together, always rounding .5 in the same direction results in a bias that grows with the more numbers you add together. This is sometimes called "Common Rounding". One way to minimize the bias is with banker's rounding. ...( read more )

Parallel Programming with Visual Basic 2010 – Part 2

by Mike McIntyre via Mike McIntyre on 2/27/2010 4:30:00 AM

This blog post provides an example of parallel programing with Visual Basic 2010. This example uses Parallel Linq (PLINQ) which is a parallel implementation of LINQ to Objects. PLINQ implements the full set of LINQ standard query operators as extension methods for the T:System.Linq namespace and has additional operators for parallel operations. PLINQ queries scale in the degree of concurrency based on the capabilities of the host computer. PLINQ increases the speed of LINQ to O ... [ read more ]

On The Blink (Matt Gertz)

by VBTeam via The Visual Basic Team on 2/27/2010 1:22:00 AM

One of the really fun things about being associated with the Visual Basic team is getting to see all of the varied usages to which our customers put it. From enterprise software to games, our customer base covers a wide range. The most fun to see, however, are the hobby applications, because the writers of that code come up with some pretty off-the-wall (but very cool) uses for it. Case in point: I was contacted two weeks ago by a gentleman named David Swoboda ... [ read more ] 5 comment(s)

The VB.Net "triple comment"

by LarryBlake via VB & .NET Blogs @ vbCity.com on 2/23/2010 12:06:00 PM

If you go into a Visual Studio method and start typing "MessageBox", you get a pop-up with some helpful text like "Displays a message box with the specified text...". As you pick one of the overloaded methods, the pop-up changes appropriately, and explains each field. For example, it might show " Text: the text to display in the message box". You can have Visual Studio give you the same hints on your own methods by using ... [ read more ] 1 comment(s)

WPF RichTextBox : How to Load and Save Plain Text Content

by Ged Mead via XTab (Ged Mead) on 2/22/2010 2:39:00 AM

The RichTextBox can be a very useful control to take in text input from a user. With minimal work, you can create a reasonable text editor based on this control. But there’s not much point in having a multifunctional RichTextBox around if you can’t save the input or redisplay it when needed. So in the next few blogs I’m going to demonstrate some of the ways you can load and save content with a WPF RichTextBox. Loading Plain Text Files OK, ... [ read more ]

Windows Interop – Inside Kernel32 Part 1 (AllocConsole & CreateHardLink)

by James Atkinson via VB & .NET Blogs @ vbCity.com on 2/17/2010 6:24:17 PM

It’s no secret that many of the .NET Framework functions are built on top of the Windows APIs. A quick visit to www.pinvoke.net provides a quick glance at many of those functions and more. While numerous of these functions are built-in to the .NET Framework, some of the more interesting ones are left aside. Here we examine two functions provided by the Kernel32.dll. Wikipedia defines the Kernel32.dll as: “Exposes to applications most of the Win32 base APIs, such as memory management ... [ read more ]
