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 […]

Fix: TortoiseHg not commiting files
04 Φεβρουαρίου 15 06:00 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   
It seems that sometimes TortoiseHg Mercurial (Hg) client on Windows fails to remove a 0-byte-sized file named “wlock” (a write lock to avoid simultaneous write to a local repository) in the “.hg” subfolder that holds a local repository. This results in the Commit dialog never commiting changed/removed/added files and you have to press Close there […]

at http://zachis.it/blog/7-dangers-of-using-windows-server-on-a-wordpress-installation/ the thing that guy says about Permalinks isn’t accurate at all (not that the other things that he says are any accurate that is).

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 […]

HowTo: use PivotViewer in WPF
04 Σεπτεμβρίου 14 02:12 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   
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 PivotViewer-compatible controls […]

Gotcha: no prefix increment/decrement VB.net operators, but get parsed
09 Αυγούστου 14 03:39 πμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   
In C/C++ and C# one has useful prefix (++index) and postfix (index++) increment operators and corresponding decrement ones. Although they have a single operant, they’re not working like functions as single + or – prefix would do, but instead they cause side-effects – they edit the variable passed to them. The prefix increment operator first […]

Trovigo.com is an unwanted search engine hijacker that renders Internet Options of Windows / Internet Explorer inaccessible.

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 pains). For example it […]
