• Drag drop library updated

  The drag drop entry that I had posted has been used by a lot of you guys out there and I have received a lot of suggestions/bugs. I also got a few ready made fixes from you... Thank You :) ... So I finally got down to incorporating all these changes and got the new library up ... One frequent problem was the adorner flickering and this was a result of the adorner being deleted and created ... so thats fixed. There are also some fixes, code moving around and the usual stuff. Hope you find the new library useful :) Library attached Share this post Read More...

• 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...

• 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: Addins

  In 3.0, we received a number of queries regarding creating plugins. So in 3.5 we got this in .. :) .. Creating an adding would bsically need the use of 3 dlls - System.Addin, System.Addin.Contract, System.Presentation The basic steps to create the addins involves creating a contract, then create the corresponding views and adapsters for both the host and the addin. So in total you will be creating 5 dlls in addition to the app and the actual addin. Even though this looks a bit overwhelming, its pretty simple. http://blogs.msdn.com/clraddins/ gives more information about creating addins. In order to try out this framework, I added the addin support to blogpad with the host being able to set text in the addins... So the app basically has an addin for a calculator (which can be removed) and an ad at the side... You can try out the code that is attached .. FYI, the ad plugin links to an xbap and this line is commented in code.. You might want to point it to a legit xbap to get this plugin working. 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...
