This is my answer at http://stackoverflow.com/questions/4475391/wpf-silverlight-find-the-name-of-a-color Modified answer from Thomas Levesque to populate the Dictionary only when 1st needed, instead of taking the cost at startup (going to use at speech recognition-driven turtle graphics, so that user can pronounce known color names to change the turtle’s pen color) //Project: SpeechTurtle (http://SpeechTurtle.codeplex.com) //Filename: ColorUtils.cs //Version: 20150901 […]

HowTo: Insert new line and spacing at content of WPF TextBlock control

While adding more voice commands at SpeechTurtle, I had to update the active legend where the available commands are displayed and their text is highlighted as the respective commands are recognized by the speech recognition engine (using .NET’s managed Speech API). A problem I faced was how to add a newline and prefixing the 2nd […]

HowTo: Free up some disk space by disabling hibernation on Windows 10

I have a small older Tablet PC (Lenovo S10-3t) that I’m running Windows 10 on, having replaced its internal classic SATA hard disk with an SSD one, and since SSD space is scarce (being more expensive I got a smaller in size disk than the original one), I needed to make free space. Since that […]

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 […]

HowTo: Open page from Internet Explorer (Metro) app into desktop IE
20 Απριλίου 15 11:03 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   
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 […]

HowTo: Delete all nodes and relationships from Neo4j graph database
18 Απριλίου 15 02:54 πμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   
At a Neo4j question in http://stackoverflow.com/questions/19624414/delete-node-and-relationships-using-cypher-query-over-rest-api, a recent reply (older ones use obsolete Cypher syntax) says: Both START and the [r?] syntax are being phased out. It’s also usually not advised to directly use internal ids. Try something like: match (n{some_field:"some_val"}) optional match (n)-[r]-() delete n,r So, to delete all nodes (including disconnected ones) and […]

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). WordPress Codex have documentation on how to configure URL rewriting in web.config that is necessery for Permalinks to work in IIS. e.g. at http://ClipFlair.net, if you press the "about" […]

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 […]

But then we get the error “The type or namespace name ‘…’ does not exist […]

Trovigo.com is an unwanted search engine hijacker that renders Internet Options of Windows / Internet Explorer inaccessible. To restore them on an older Windows XP installation, one way that I’ve found to work is to update Internet Explorer to a newer version, aka IE 8 (say via the embedded Windows Update facility or Microsoft Update […]

HowTo: Drop files onto Silverlight controls
27 Μαρτίου 14 05:14 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   
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 […]

I think Timer runs the code in its own thread, so you […]
