• MindMap app using Hyperbolic tree

  I recently came across a Hyperbolic tree implementation on codeplex using WPF and thought that a nice usage of it could be in writing a mind map creating application.... I tweaked some of the original code and got a tree with editable nodes... Its been laying around for sometime, so I thought it best to put it out there so that you folks can continue its development. Though its not functional in the true sense, it does provide the basic functionality like saving and opening (albeit to the same file)... Currently only the text is serialized... The project (VS 2008) is attached Note that the usage of the Hyperbolic tree and its code is under the Codeplex License terms Share this post Read More...

• .NET Source code

  Now thats what I call WOW ... For .NET developers this is like getting hold of the holy grail :) ... " We'll begin by offering the source code (with source file comments included) for the .NET Base Class Libraries (System, System.IO, System.Collections, System.Configuration, System.Threading, System.Net, System.Security, System.Runtime, System.Text, etc), ASP.NET (System.Web), Windows Forms (System.Windows.Forms), ADO.NET (System.Data), XML (System.Xml), and WPF (System.Windows). We'll then be adding more libraries in the months ahead (including WCF, Workflow, and LINQ). The source code will be released under the Microsoft Reference License (MS-RL). You'll be able to download the .NET Framework source libraries via a standalone install (allowing you to use any text editor to browse it locally). We will also provide integrated debugging support of it within VS 2008. " Read the complete post at Scott's blog Share this post Read More...

• Testing using WPF UI automation

  One question that often pops up among WPF app developers is UI testing... WPF enables this scenario through a new accessibility framework.

• 3.5 features: Viewport2DVisual3D

  Viewport2DVisual3D .... this new feature makes things a lot easier in the 3D world.. What this enables is putting interactive 2D on 3D. This makes things like having a textbox in 3D a breeze... < Viewport2DVisual3D x:Name = " vp2d_multiple_children " Geometry = " {StaticResource mesh} " > < Viewport2DVisual3D.Material > < DiffuseMaterial Viewport2DVisual3D.IsVisualHostMaterial = " True " Brush = " White " /> </ Viewport2DVisual3D.Material > <TextBox /> </ Viewport2DVisual3D > One other thing is mapping 3D points to 2D is so much more easier... Earlier on I had a post on mapping a mouseclick on a 3d model to a 2d coordinate. This involved using some barycentric coordinates and such... Now all you need is call e.GetPosition(relativeTo) in the mouse event handler... tada!!... your coordinates are ready... so using this new stuff i created a simple app for keeping track of your travels. right clicking on the globe puts a tag on the globe. Clicking on the Read More...

• 3.5 Features: Enabled hyperlinks in RichTextBox

  hmmm... that was one often requested feature. So to enable hyperlinks in RichTextBox all that is needed is to set the property IsDocumentEnabled on the RichTextBox. Type the following in XamlPadX and you have the hyperlink navigation working. < RichTextBox IsDocumentEnabled = " True " xmlns = ' http://schemas.microsoft.com/winfx/2006/xaml/presentation ' xmlns:x = ' http://schemas.microsoft.com/winfx/2006/xaml ' > < FlowDocument > < Paragraph > < Hyperlink NavigateUri = " http://club.live.com " > Live Games </ Hyperlink > </ Paragraph > </ FlowDocument > </ RichTextBox > A couple of things to notice here: 1> The Navigation is possible only on a Ctrl Click operation 2> There is no tooltip to indicate that navigation is possible. You could add this to the Hyperlink. A simpler alternative is to just subclass the Hyperlink and add the tooltip in the constructor public class MyHyperlink : Hyperlink { public MyHyperlink() { this .ToolTip = Read More...

• 3.5 features: Filtering text with IME languages

  So 3.5 beta2 is out and it has quite a lot of features. So one of them is the filtering mechanism for IME languages. This was not a problem in the english and other non-IME languages. The problems were the events associated with IME input - TextInputStart/Update/input... A major concern was that it was not possible to determine where the composition took place. Now all these issues have been fixed and filtering in these languages is a breeze. I came up with a sample calculator with the filtered IME textbox which shows how the filtering is done for IME languages. If you go through the code, you will notice that min max positions of the composition are tracked in the events to determine the correct caret position after the filter is applied. The textbox takes any ime input and filters the characters after the composition is complete. The sample project is included to demonstrate the usage of the events. The project also includes a filtered richtextbox even though its not used in the demo Read More...
