HowTo: Tell AddThis to not append tracking suffix on addressbar
20 Νοεμβρίου 12 12:24 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

ClipFlair’s project description website is based on WordPress (a quite extensible blogging platform based on PHP). The other day we had an issue with the AddThis Plugin for WordPress, which was adding tracking suffices (in the form #.UAxxxxx) to the end of our URLs on the browser address bar. Moreover this wasn’t occuring in Internet [...]

HowTo: Multi-row captions and wrapping at Silverlight Media Framework
19 Νοεμβρίου 12 06:27 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

One of the main goals of the ClipFlair project is to explore the use of Video Captioning (together with Revoicing) for Foreign Language Learning (FLL). There both are important enhancements compared to the simpler two-line subtitling that was put in use in its ancestor project LeViS. Captioning means that multi-row text is needed while text [...]

HowTo: Check MSDN Subscriber downloads for tampering via SHA-1 key

Supposing you have an MSDN Subscription, you could download say SQL Server 2012 Standard Edition (x86 and x64) – DVD (English) from the following URL: http://msdn.microsoft.com/en-us/subscriptions/downloads/hh442898.aspx#FileId=48810 Suppose you do so and you keep that .ISO file (a CD/DVD image that you can burn to a disk using Windows 7 or Active@ ISO Burner tool, or [...]

HowTo: Hide Video area of Silverlight Media Framework Player
03 Οκτωβρίου 12 12:25 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

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 (http://lvs.codeplex.com/workitem/11511) was titled “Allow video hiding while [...]

HowTo: load CaptionElements into Silverlight Media Framework player
03 Σεπτεμβρίου 12 03:38 πμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

Trying to make CaptionsGridWindow of ClipFlair serve captions editing on-the-fly to SMF (Silverlight Media Framework [now called MMPPF]) player component, I had a real hard time, plagued by a bug at TimedTextElementStyle. It seems to be setting default FontSize for captions using a “Cell” unit instead of using a “Pixel” unit. Currently SMF only supports [...]

HowTo: Scale control arround its center using a render transform
15 Αυγούστου 12 07:02 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

In the context of ClipFlair development, I was recently adding independent scaling (zooming) functionality to its ZUI container’s floating windows (apart from the container zooming functionality) and came across some strange behavior, where the windows seemed to also move apart from getting scaled. After banging my head a bit I decided to take a closer [...]

HowTo: Bind to a DataContext property named Source in XAML
14 Αυγούστου 12 03:27 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

While refactoring ClipFlair code to use MVVM (Model-View-ViewModel) pattern, I came across the XAML error “Object reference not set to an instance of an object.”, shown in Visual Studio when trying to bind to my ViewModel (accessed implicitly, being set as the DataContext of the XAML control) for a property named Source. I have settled [...]

HowTo: Compress speech audio using CSpeex codec at Silverlight apps
04 Αυγούστου 12 07:15 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

Following up on my post on how to fix CSpeex (http://cspeex.codeplex.com) to compile at Silverlight 5 (see http://zoomicon.wordpress.com/2012/06/09/fix-compile-cspeex-audio-codec-at-silverlight-4-rc-and-silverlight-5/).  Initially I thought it was not working correctly, but then I noticed I was running it on Terminal Server and didn’t have an audio device available. Running SLAudioDemo included in the CSpeex distribution (after doing the fix [...]

Vertical Centering with CSS
03 Αυγούστου 12 04:50 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

According to http://www.w3.org/Style/Examples/007/center.en.html#vertical CSS level 2 doesn’t have a property for centering things vertically. There will probably be one in CSS level 3. But even in CSS2 you can center blocks vertically, by combining a few properties. The trick is to specify that the outer block is to be formatted as a table cell, because [...]

How to space StackPanel items in XAML (has no Padding property)
11 Ιουλίου 12 01:34 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

While adding some properties to the back panels of ClipFlair windows, I came upon the issue of how to space items in a StackPanel. A Padding property is missing from multiple item containers (only single content controls have such), but a nice solution is described at: http://stackoverflow.com/questions/932510/how-do-i-space-out-the-child-elements-of-a-stackpanel Sergey Aldoukhov suggested there (WPF example): Use Margin [...]

HowTo: Set UI language (CurrentUICulture) in Silverlight
20 Ιουνίου 12 04:11 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

At LvS (the opensource application of LeViS), I’ve been using this (VB.net) code to set the UI language (for example to Greek): Thread.CurrentThread.CurrentUICulture = CultureInfo.GetCultureInfo("el") Others seem to have been using (C# – that’s why there is a trailing semicolon): Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture("el"); assuming System.Globalization and System.Threading namespaces have been imported. However, now that I’m [...]
