Dismissing All Loading Overlays in Ionic 4

August 16th 2019 Ionic 4/5 Async

In Ionic 4, the dismissAll method for closing all currently open loading overlays has been removed. This might not be such a bad idea since it could cause problems when used carelessly. Still, when porting an existing Ionic 3 app to Ionic 4 not having an equivalent for it available can be a problem. I created my own replacement to make porting easier and minimize the required code changes.

Returning Results from Alerts in Ionic 4

June 28th 2019 Ionic 4/5 Async

Last year I wrote a blog post about making code for displaying alerts reusable and testable by wrapping it into a function which returns the user's response as a promise. The sample was written in Ionic 3. The code doesn't work in Ionic 4 without modifications. Since I recently received a request for an Ionic 4 version of the code, I decided to write this follow-up post.

Angular Tutorial with Async and Await

January 27th 2017 Async TypeScript Angular

In version 2.1 that was released in December 2016, TypeScript finally added support for downlevel transpilation of async and await keywords for ES3 and ES5 targets. To give this new feature a try, I decided to convert the Angular Tour of Heroes tutorial to use async and await.

It's May again, which means the annual NT Conference was taking place in Portoro┼ż at the beginning of this week. This year I had two sessions scheduled, the first one on Monday and the second one on Tuesday.

Unit Testing Asynchronous UI Code in WinRT

December 9th 2013 Windows Store Unit Testing Async

Writing unit tests for code that needs to be run on the UI thread can be quite a challenge in WinRT. TestMethodAttribute supports asynchronous test methods but doesn't run them on UI thread. UITestMethodAttribute runs test methods on UI thread but doesn't support asynchronous methods. Still, I managed to make the test method asynchronous and run it on the UI thread.

Wrapping Other Asynchronous Patterns in Awaitable Tasks

July 22nd 2013 Async .NET Framework

Writing asynchronous code in .NET framework 4.5 is pure joy thanks to task-based asynchronous pattern (TAP) and the async/await syntactic sugar. Although many APIs have been updated since the introduction of TAP to provide task based asynchronous methods which can be used with async and await, occasionally you will still encounter operations in APM (Asynchronous programming model) or EAP (Event-based asynchronous pattern) without a TAP equivalent. Fortunately .NET framework provides helpers which will make wrapping older style asynchronous operations into tasks much easier.

Calling Task-based Asynchronous Methods from Class Constructors

Task-based asynchronous pattern has many advantages over other asynchronous patterns introduced in the past, most of them boiling down to the fact that it's really easy to get into and start using it. Like any other technology, it does have its pitfalls and there are many details to know about once you get into more advanced scenarios.

What's New in .NET Framework 4.5 Session from Visual Studio 2012 Bootcamp

On Monday our local Microsoft subsidiary organized Visual Studio 2012 bootcamp as a preconference to Bleeding Edge 2012. For my talk I selected 3 new features in .NET Framework 4.5 that excite me most.
