I’ve managed to combine http://www.codeproject.com/Articles/85603/A-WPF-custom-control-for-zooming-and-panning and a cut-down version of it for Silverlight that was out there: http://www.codeproject.com/Articles/167453/A-Silverlight-custom-control-for-zooming-and-panni I did it in a way that the Silverlight version is source-code compatible ...

System.IO.IsolatedStorageSettings doesn’t exist in WPF (only in Silverlight) but can easily be ported from Mono project’s Moonlight implementation (the Moonlight project home is at http://www.mono-project.com/Moonlight), as suggested at: http://groups.google.com/group/wpf-disciples/browse_thread/thread/4ed6c009f3fb7d69 I found that ...

Just came across http://wangmo.wordpress.com/2007/09/27/themesgenericxaml/ which gave me a hint on why a WPF control wasn’t getting instantiated correctly when loaded from an external assembly (dll): to load generic.xaml for WPF, at the start of Properties\AssemblyInfo.cs you need (note this isn’t used/needed in Silverlight): using System.Windows; ...

Using Microsoft Web Platform Installer (aka WebPI), one can easily install WordPress on IIS (together with PHP and MySQL database engine. Btw, better install the latest PHP version from there and remove any older ones. Also do install from there the  Windows Cache Extension for PHP for the version of PHP you’re using.

Copying from MPPVE (formerly RCE) documentation: …might indicate that WCF is not correctly configured. To resolve the WCF issue The error returned is a “HTTP Error 404 – Not Found”. This might be due to an issue with the WCF scriptmaps registrations. To solve this issue: Open a command line console as Administrator Browse to [...]

I’ve been looking into porting Kael Rowan’s ZoomableCanvas (related to ZUI code used in Code Canvas, Debugger Canvas etc. VisualStudio add-ons) from WPF to Silverlight. One of the issues I found was that Silverlight’s Rect class (I guess this is a case for .NET Compact Framework in general) doesn’t have a method to check if [...]

Πρόσφατα το Taxisnet έδωσε άτυπη παράταση χρήσης της εφαρμογής περιουσιολογίου για τον έλεγχο και διόρθωση (χωρίς πρόστιμο) των παλαιότερων δηλώσεων E9 (μεταβολών περιουσιακής κατάστασης) για τις ημερομηνίες 1-1-2009, 1-1-2010, 1-1-2011, που κανονικά έληγε τέλος Μαρτίου.

Since widescreen format in monitors gets more and more common, how about a twist to the classic tabbed windows UI? Imagine being able to pin a tab and have it move to a side-view area in the same window. That are would keep the pinned tabs separated from the rest using a splitter / split-view [...]

A nice quote from ClipFlair project’s (http://clipflair.net) internal mailing list (the formatting is mine for your convenience): …difference between Dissemination and Impact: Impact is the measure of dissemintation.   For example: - Organising a conference is dissemintation.  - Number of people attending the conference is impact. - ...

Hello Microsoft, can you count? In the image above you can see the Windows 7 taskbar showing THREE (merged) icons/instances of Internet Explorer, although I only have ONE windows open (they seem to use multiple processes internally when you have many tabs, but why should the user care?). More importantly, in the popup shown when [...]

Ahem, Microsoft Connect says I can’t Connect (sign-in) to it for the moment. The Microsoft bug reporting site probably came upon some bug itself? #LOL Tagged: Bugs, Feedback, Microsoft

Όταν πρωτοκυκλοφόρησε το εκπαιδευτικό λογισμικό ΓΑΙΑ ΙΙ (το 2002) δεν υπήρχαν ακόμη τα Windows Vista και Windows 7, οπότε χρειάζεται μερικά παραπάνω βήματα από τα συνήθη η σωστή εγκατάσταση του.

A reader of my recent article on a page faking YouTube design to lure you into subscribing for a pay-per-message you receive scheme for mobile phones, told me that they came across a very similar one by typing wikipdia.org instead of Wikipedia.org.

A friend just called me this morning that their notebook with Windows 7 Starter started today showing the same icon for every Start menu item and for shortcuts (e.g. on the desktop) and when trying to open them the same program would always try to open them.

Πήγα και εγώ χθες στην εφορία μου κι έλαβα τον κλειδάριθμο για να πιστοποιήσω το λογαριασμό που είχα από παλιότερα (στο παλιό TAXISnet) – έδωσε και νέο password όπως μου ζήτησε και μπήκα να δώ τι καλούδια έχει.
