• ABCs of Threat modeling ...

  Larry Osterman has an interesting series of posts on Threat modeling.. It starts from the basics and is very comprehensive. A application needs to go through the threat modeling process to identify possible threats, the mitigations, and the risks involved. From a tester's perspective it opens up several testing scenarios. So if you are unfamiliar with this topic or its something which needs some brushing up, give the posts a look :) ... Happy reading 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: 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...
