The Windows 8/8.1 app version of Internet Explorer is also known as IE Metro because of the “Metro” codename (inspired by navigation signs in public transport] of the Modern UI design language promoted by Microsoft). However that version isn’t the full Internet Explorer, in that it is unfortunately not supporting extensibility via plugins in the ...

My comment at: https://github.com/loarabia/ManagedMediaHelpers/issues/16 While trying to use Mp3MediaSource at ClipFlair Studio’s AudioRecorder control (http://clipflair.codeplex.com), I noticed that when I was doing Stop() at MediaElement and then Play() it kept on playing from where it was before at Mp3MediaStreamSource So I did the ...

At ClipFlair’s AudioRecorderControl (used in Captions/Revoicing component of ClipFlair Studio), I use the following code to initialize a MediaElement to use for playback. After a long time a found out that if the MediaElement is not in the visual tree (for example defined in XAML, or defined in code and then added to the visual […]

Just added the following comment to: https://github.com/loarabia/ManagedMediaHelpers/issues/15 Managed Media Helpers contains the very useful Mp3MediaSource class for .NET / Silverlight / Windows Phone. Added compile-time SWITCHES and respective code to Silverlight demo code for PRELOAD (into memory stream) and AUTOPLAY (this was a bit tricky, ...

Just fixed a nasty bug in ClipFlair Studio (http://studio.clipflair.net), where one couldn’t click hyperlinks in the Text component when set at ReadOnly mode. In that mode hyperlinks should open up new web pages (in Edit mode you can edit/remove them only of course), but instead when clicked they would show something like a focus rectangle ...

PivotViewer is an impressive Silverlight control (see my usage at http://gallery.clipflair.net), however Microsoft never released it for WPF. One could work arround this by embedding Silverlight in their WPF app using the WebBrowser control and talking to it via the JavaScript Bridge of Silverlight, however they could also embed one of those HTML5 ...

at System.IO.Path.GetInvalidPathChars one reads: The array returned from this method is not guaranteed to contain the complete set of characters that are invalid in file and directory names note: can also call this method from non-trusted Silverlight app – not as Intellisense tooltip wrongly says in Visual Studio 2013 with Silverlight 5.1 I ...

I was recently adding drop-files support to ClipFlair Studio, so I had to do some research on the related API that is available to Silverlight apps. Silverlight supports a limited set of Drag-and-Drop interaction with the operating system (supposedly for security reasons, but most probably because of the classic cross-platform implementation ...

It seems that CaptureMouse is behaving differently in WPF and Silverlight, in that in the former one it immediately calls OnLostMouseCapture at a Visual, whereas in Silverlight it doesn’t get called if the element didn’t have the mouse capture already (btw, in Silverlight that method is at a UIElement – there is no Visual ...

I was looking into some third-party code, upgrading it from Silverlight 4.x and was getting error ‘The member "Content" is not recognized or is not accessible’ at the following code part: Looking it up, found that you don’t need to bind the Content property of a ContentPresenter at all if you put it inside the […]

My contribution to http://stackoverflow.com/questions/1101841/linq-how-to-perform-max-on-a-property-of-all-objects-in-a-collection-and-ret Based on  another answer there, here is what I’ve just added to my enhanced version of SilverFlow library’s FloatingWindowHost (copying from FloatingWindowHost.cs at ...

At ClipFlair Studio (a Silverlight app), I had some time ago implemented a confirmation warning upon user trying to close the webpage (when it was running inside the web browser), which then had stopped functioning. It seems at some refactoring I had added code like the following: var activityView = activityView(); and it was failing […]

One of our ClipFlair Studio users reported on having some issue trying to install Silverlight on MacOS-X, so I gathered some related info below:     First of all, at the Silverlight installation webpage, at the System Requirements tab, you can find the following requirements: Macintosh (Intel-based) Intel Core Duo 1.83-gigahertz (GHz) or ...

based on the other samples posted at StackOverflow on how to format XML created by DataContractSerializer, that use XmlWriter, here’s a version (from ClipFlair source code) that works with streams (and Ionic.Zip library in specific). It also shows how the code is when you don’t apply formatting (using conditional compilation).  ...

I was just adding a storable (persistent) Volume property to the MediaPlayerView class used at ClipFlair’s MediaPlayerWindow (connected to the underlying SMF player’s VolumeLevel property), when I realized that after reloading saved state, the SMF player’s Volume control would show a different value than the value set to it (which I could confirm ...

At ClipFlair’s Image component I use the following XAML to make it show an image from a URL that its ViewModel holds at a property named “Source”, of type Uri (URI = Uniform or Universal Resource Identifier in W3C parlance, something like a superset of the old classic URLs). <Image Name="imgContent"        ...

While stepping through “ShowDialog()” method of OpenFileDialog with Visual Studio 2010 debugger, at the Silverlight code pictured below (for loading a ClipFlair window’s stored options), I got a “Dialogs must be user-initiated” exception. Same behaviour will be shown with SaveFileDialog too, every time you try to step through the “ShowDialog()” ...

For ClipFlair, I’m looking into implementing advanced search using Silverlight PivotViewer   A really nice example of PivotViewer search is at: http://www.appletoncompassion.org/VirtualExhibitViewer This may take long time to load, since its loading 10000 children art DeepZoom image tiles You can use the mousewheel to zoom in there or the ...

Project Linker is a Visual Studio Extension that “helps to automatically create and maintain links from a source project to a target project to share code that is common to Silverlight and WPF”. In ClipFlair, where I have shared code between a Silverlight and a WPF project (I guess same would be for XNA projects [...]

If you want to use the latest DotNetZip library (version 1.9.1.8) with Silverlight, you should get a patched version from http://dotnetzip.codeplex.com/workitem/14049, instead of the official download for Silverlight. It seems the Silverlight build in 1.9.1.8 official download doesn’t work correctly, since it tries to get IBM437 Encoding (as ...

At ClipFlair’s Playground Silverlight app I’m using DotNetZip library (Ionic.Zip namespace) for writing saved component state to a .ZIP file. In fact the Activity container there can create one .ZIP for each state that contains one .ZIP per-component it hosts (it can even host multiple instances of its own Activity componnt type to have nested ...

Since our onoing project ClipFlair is a follow-up of the succesful project LeViS, during its development I’m also looking at covering possible use-cases I infer from feedback entries at LvS application issue tracker on Codeplex (note that ClipFlair is also opensourced on Codeplex at http://ClipFlair.codeplex.com). One such issue ...
