28 Δεκεμβρίου 15 06:34 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

I was setting up a new Lumia phone (with Windows Phone 8.1) and neither phone update, nor the (Here) maps downloads were working. When trying Settings / Phone Update, it was showing error 80072f8f and was pointing to http://www.windowsphone.com/en-us/how-to/wp8/basics/solutions-to-update-issues to read more info. However that error code wasn’t listed there. Wonder if there is any […]

Suggestion: If and while etc. clauses should accept bool? in C#

At TrackingCam app (http://TrackingCam.codeplex.com) I have the following WPF code, where cbTrackingPresenter is a CheckBox control defined in my MainWindow’s XAML: private void cbTrackingPresenter_Checked(object sender, RoutedEventArgs e) {       if (cbTrackingPresenter.IsChecked == true)           StartTrackingPresenter();       else           StopTrackingPresenter(); } Note the (redundant in my opinion) == true pattern used there. If the == true […]

Suggestion: Add Fullscreen and Pin buttons on Titlebar of Windows
09 Δεκεμβρίου 15 05:53 πμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

Here are some suggestions I’ve sent via Windows Insider feedback app for Windows 10: 1) Add the Fullscreen button to titlebar of ALL windows, not just the ones of Windows 8.1 Store apps. UWP (Universal Windows Platform) apps don’t seem to show zoom button on their titlebar (to make it and any borders autodisappear and […]

HowTo: show inner exception message if available, else outer one
09 Δεκεμβρίου 15 05:44 πμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

Sometimes when you catch an exception in .NET, the message it prints out isn’t very informative, since it is wrapping another exception that had been thrown a bit inner in the code. That exception is in that case accessible via InnerException of the Exception instance. That inner exception is also an Exception, so one would […]

Suggestion: C# static extension methods invokable on class type too
09 Δεκεμβρίου 15 05:30 πμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

it would be nice if C# supported syntax like: public static DependencyProperty Register(static DependencyProperty x, string name, Type propertyType, Type ownerType, FrameworkPropertyMetadata typeMetadata) that is static extension methods for classes, that can be invoked without a class instance (just with the class type), apart from normal extension methods that can be invoked on a class […]

HowTo: Pause and Resume Speech Recognition with Microsoft engines
07 Δεκεμβρίου 15 09:59 πμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

At SpeechTurtle application, I’ve just added speech feedback (voicing of a command) when an available command is executed using a mouse click on its name. That could also help the user learn the expected pronunciation in English in case the speech recognition engine doesn’t understand some of the commands as voiced by the user. One […]

Based on others answers at http://stackoverflow.com/questions/3123870/find-the-location-of-my-applications-executable-in-wpf-c-or-vb-net here’s an example that shows how to remove the executable name from the path and combine the result with some subfolder and filename: At my updated version of Hotspotizer (http://github.com/birbilis/Hotspotizer), I’ve just added support for loading a Gesture Collection file at startup, if found at Library\Default.hsjson, by using the […]
