Gotcha: WPF UserControl SizeChanged event not firing at resizing
28 Νοεμβρίου 15 04:15 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

Useful to know: If you set the Width and Height on the UserControl though, you have set a fixed size and thus even if its parent tool window changes size, the UserControl never will.  You should not set Width and Height on the UserControl if you want that event to be raised as the parent […]

Gotcha: MarkerReached event of MediaElement returns new Markers
20 Μαρτίου 15 08:50 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

I just checked in the implementation code for a new feature for ClipFlair Studio’s Captions/Revoicing component: When playing back recorded (or loaded from a WAV or MP3 file) audio for a caption/revoicing entry, the playback is now limited to the duration of the respective caption, (End-Start) time that is (btw that component has a duration […]

Gotcha: MediaElement must be in visual tree for MediaOpened, MediaEnded to be fired
18 Νοεμβρίου 14 04:18 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

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 […]

Gotcha: MediaElement AutoPlay faster than doing Play at MediaOpened
18 Νοεμβρίου 14 02:27 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

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, need to call Play at MediaOpened event, not right after […]

Gotcha: OnLostMouseCapture always called by CaptureMouse at WPF
14 Μαρτίου 14 12:08 πμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

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 ancestor […]

Gotcha: var x = x() in Javascript gives “Object Expected” error
14 Ιουνίου 13 12:27 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

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 […]
