From LINQ to SilverLight – Watch videos and hear about all the cool technologies coming and the people behind them. http://channel9.msdn.com/Forums en Wed, 22 May 2013 22:50:16 GMT Wed, 22 May 2013 22:50:16 GMT Rev9 14 -14 -1 The Sandbox - My first Avalon application: DesktopClock Just playing with the new WinFX SDK, and the result is my first Avalon application, a desktop clock. Contains simple scalable vector graphics.

Built with VS2005 beta 2 and WinFX SDK beta 1 RC.

Sources and binaries are included. A good (but simple) demo for the transformation features of Avalon.

EDIT1:

Context menu added, right click to reach it. You can choose a smoother, nicer animation-like update method, but that consumes more processor cycles.

I wanted blurred shadows but there are no image effect classes, left out in this release.

What did you use to create the vector graphics? I've been looking for an image editor to create vector graphcis with.

There’s nothing special. There are lines only and text for the numbers. The most interesting thing of this application is its simplicity. The scaling feature is about 5-6 lines of coding. The canvas has a scaling transformation and when its size changes the scale factor is updated.

Avalon is a great developing platform. It would be nice to work with Avalon sooner. I can experience its strength while I developed this tiny application. I recommend learning it for everybody.

One suggestion: you can use Viewbox element which automatically scales its content so you don't have to handle the scaling yourself.

So the XAML code will look something like that:
<Viewbox Stretch="Uniform">
    <Canvas x:Name="canvas">
...

Really! I learned a new thing. Thanks. I have updated it.

I am not certain whether these problems are with Avalon or the app. But here goes:

Build a release version and run it out of VS (just to be sure there's no/less debug code).

Now open up task manager and the cpu usage graph. Now run the app and put the continous update mode.

Watch CPU usage graph rise for a minute or so.

You can try minimize the app and the cpu usage stays same.

I have created some performance session with not too big result:
The System.Windows.Media.RotateTransform.set_Angle(float64) function takes longest within the UpdateClockHands function.

I have inserted a line into the UpdateClockHands function which outputs the "n" TimeSpan variable values. UpdateClockHands called normally by 50 msecs as given to the DispatchTimer.Interval property.

I'm not sure, it's a bug or not.
