However, because the component serialization file format of ClipFlair Studio is XML plus media assets packed in .zip archive (with nesting allowed, where components and whole activities can be placed in other activities), Internet […]

Suggestion: Visual Studio should offer to implement callbacks 30 Νοεμβρίου 15 06:01 πμ | Μπιρμπίλης Γεώργιος | 0 σχόλια: I type-in new PropertyMetadata(OnCenterXPropertyChanged) but since I haven’t yet implemented On…, I get a suggestion by the IDE to implement it but it suggests to add field, property or read-only field, not to implement the callback for me with the given name.

HowTo: Use MEF to implement import/export etc. plugin architecture 03 Ιουνίου 15 01:13 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια: Copying here my comment at a discussion on the GraphX project: https://github.com/panthernet/GraphX/pull/15 in case it helps somebody in using MEF (Managed Extensibility Framework) in their software’s architecture ——– Using static classes instead of interfaces can mean though that you need to use reflection to call them (e.g. if you wan to have a list of […]

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 […]

HowTo: Use WordPress Permalinks on IIS 29 Οκτωβρίου 14 10:28 πμ | Μπιρμπίλης Γεώργιος | 0 σχόλια: 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).

Fix: Hypelinks not clickable in RichTextBox under Silverlight 07 Σεπτεμβρίου 14 04:18 πμ | Μπιρμπίλης Γεώργιος | 0 σχόλια: 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.

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 […]
