WriteableBitmap is quite useful when app requires image processing. It provides a BitmapSource, which can be written & manipulated. Ultimately that bitmap source is supplied to image control of Windows 8 app. Majorly WritableBitmap is more used with WriteableBitmapEx library, which is a collection of extension methods for the WriteableBitmap. But we won't go for manipulating

WebView is a control which enables developers to host the HTML content. In WinRT framework WebView still lacks some features when we compare it to the WebBrowser of WPF. WebView class inherits from FrameworkElement class, but many properties of base class in not working in WebView. Recently I was creating an app and I want to disable the horizontal & vertical scrolling of WebView. I tried

Introduction Microsoft's documentation & sample for printing is too much complex. The sample app for printing shows only how to print RichTextBlock. There's no tutorial to print the TextBox content in Windows Store app. Moreover to print single line of string, one has to write too much code rather than maximum 10 lines in WinForm. So this helper class provides simplest method to print the

One of the many new features with upcoming Windows 8 is the Windows Store distribution and monetization channel. Developers can now add in-app purchasing to their apps. The prizes are the same as application prizes in store, e.g. starting from 1,49 USD (1,19 EUR) and gradually growing up in 50 cent increments. Because it seems testing in-app purchasing system isn’t trivial to everybody, here’s a

I wanted to create a simple ALT+S shortcut in my app to jump to a TextBox in my Windows Store App (no this is not the Win+Q search charm shortcut). However, this is not that obvious to get working app-wide, so I’ll share it here:The obvious way to do this is assign a KeyDown event to your page using the typical “this.KeyDown += MyKeyDownHandler”, or override OnKeyDown. However this has one

It has been work around to have more than one data template in a list to display the data. In Windows 8 it has been eased, WinRT introduces the DataTemplateSelector class, where we could have more than one template to display in an items source control in Windows 8. In this article we would discover that.To explore the sample, you definitely need Windows 8 Consumer Preview and Visual Studio

It’s always a good idea to test your application before submitting it to the store. The Windows Application Certification Kit (WACK) tool can save you from failing the early automated tests.The first thing you’ll want to do is uninstall any existing build of your application. This is important because the WACK tool may fail if a previous debug build is still installed on the system. To

By default Bitmap Images are cached by WinRT with no intervention required by the developer.  Often times this is a good thing but there are some occasions where this is undesirable.  Although there doesn’t appear to be any obvious control in the API reference I have found that adding a dummy querystring to the BitMapImage source filename reference does the trick and also can offer

Protocol activation, what is it? Well, when you run “http:{something}” you expect a browser to launch, right? When you type “mailto:{something}” you expect a mail client to launch, right?

There is a lot of different file format when it comes to 3D objects. One of the most used is the FBX from Autodesk. This file format can be exported by all major DCC but the key point is that it can be complex for a game or 3D developer to open such file format. I would like to propose here a solution that can allows you to easily offline files importation. The idea is to simulate a MSBuild

Windows 8 is changing how and when applications run, and you’ll want to understand the nuances of the new application lifecycle so you can build apps that respond as they should at every point. Apps that conform to the Microsoft lifecycle management guidelines offer a better experience for the user, especially on small devices where memory and battery conservation are warranted. Read More

Any programmer with previous experience in any of the XAML-based frameworks has probably at least heard of the Model-View-ViewModel (MVVM) pattern. Some have been using it extensively in all of their Windows Presentation Foundation (WPF), Silverlight or Windows Phone applications. Others have avoided it, either because they misunderstand what the pattern does, exactly, or because they don’t

You can avoid performance bottlenecks and enhance the overall responsiveness of your application by using asynchronous programming. However, traditional techniques for writing asynchronous applications can be complicated, making them difficult to write, debug, and maintain. Visual Studio 2012 introduces a simplified approach, async programming, that leverages asynchronous support in the .NET
