#1,190 – VisualChildrenCount and GetVisualChild

AddThis Social Bookmark Button
A FrameworkElement provides the VisualChildrenCount property and the GetVisualChild method, typically used during layout to walk through the child elements of the element participating in layout.  When you create a custom control that derives from FrameworkElement, you typically override both members, providing values that make sense for your control. Below, we use these members to get a report of the visual children […]

Implementing an F# Signal Generator

AddThis Social Bookmark Button
As part of a larger project I have been working on a signal generator. A signal generator is a device (in this case an F# program) that is often used to generate waves at a particular frequency that can be interpreted as sound (by applying to a speaker as a voltage). For my project I want to generate pitches and then convert the signal to PCM audio data, wrapped in the windows WAVE file format. PCM format means that the signal is represented as a series of positive or negative values within a certain range. The number of samples per
second is called the sample rate (44,100 for CD audio). The range of the values is governed by the bit depth, again I will stick with the CD audio standard 16 bit audio, giving me a range of -32768 to 32767. Generating Signals The simplest and purest representation of a particular frequency is given by a sine wave. This graph was generated using FSharp.Charting and the following fsx file #load "../packages/FSharp.Charting.0.90.7/FSharp.Charting.fsx" open FSharp.Charting let c = seq { for x in [1.0..0.1..20.0] do yield (x, sin x) } |> Chart.Line Note that the wave has a range from -1 to 1 and a recurring regular frequency....(Read whole news on source site)

If you configure Active Directory Federated Services (ADFS) you can use corporate identities with existing VSO accounts. Link to your internal domain and you can get a completely seamless Single-Sign-on from your local network to the cloud for Office 365, SharePoint Online, and now Visual Studio Online (VSO). The post Use corporate identities with existing VSO accounts appeared first on naked ALM - Experts in ALM, TFS & lean-agile with Scrum.
