Silverlight 6 Hosting - HostForLIFE.eu :: How to Control Playback in A Video

clock September 17, 2015 11:07 by author Rebecca

Using videos in a Silverlight based application is a very exciting feature. In this article, we will learn how we can control the playback of movie using some coding in code-behind. Let's see how!

Dealing with Automatic Start

By default videos automaticall get started when we run the project, it is distracting feature from the users point of view. To change auto start false, select the video on stage and in properties uncheck the 'AutoPlay' option.

Dealing with Endless Playback

By default, when the video reaches the end then it stops and does not start again. To change such a setting follow the steps:

1. Select the video on stage

2. In Properties, switch the mode from 'Properties' to 'Events'.

3. In the Event list, point to 'MediaEnded' label and type the event handler name (I will be using md_ended_eve) and then press tab to apply it and it automatically switches you to code-behind with a new event.

4. Now type the following code inside event handler:

(intro_wmv).Stop();
(intro_wmv).Play();

In above code 'intro_wmv' is my media fine name.

5. Now test the application.

XAML Code
<Grid
          xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
          xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
          x:Class="SilverlightApplication1.MainPage"
          Width="640" Height="480">
          <MediaElement x:Name="intro_wmv"
          Margin="54,64,104,60"
          Source="/intro.wmv"
          Stretch="Fill"
          MediaEnded="md_ended_eve" AutoPlay="False"/>
</Grid>

XAML.CS Code
using System;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Ink;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
namespace SilverlightApplication1
{
       public partial class MainPage : Grid
       {
              public MainPage()
              {
                     // Required to initialize variables
                     InitializeComponent();
              }
              private void md_ended_eve(object sender, System.Windows.RoutedEventArgs e)
              {
                     // TODO: Add event handler implementation here.
                     (intro_wmv).Stop();
                     (intro_wmv).Play();
              }
       }
}

Control Video Playback by Pause and Play

By default in Silverlight video plays and we can't control it by pausing and playing. But by writing some lines in code-behind we can control this playback. For this we have to create the event as we saw in above example. Let's follow the steps:

1. Open the event explorer by switching the property (look above image).

2. Type the event name in 'MouseLeftButtonDown', I will be using here 'pause_start_evn' and press tab to switch in event handler mode.

3. In the appeared event type the following code:

private bool IsPaused=true;
private void pause_start_evn(object sender, System.Windows.Input.MouseButtonEventArgs e)
              {
                     // TODO: Add event handler implementation here.
                     if(IsPaused)
                     {
                           (intro_wmv as MediaElement).Play();
                           IsPaused=false;
                     }
                     else
                     {
                           (intro_wmv as MediaElement).Pause();
                           IsPaused=true;
                     }
   }

4. Now test the application and check by right mouse click on video surface.

XAML Code
<Grid
          xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
          xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
          x:Class="SilverlightApplication1.MainPage"
          Width="640" Height="480">
          <MediaElement x:Name="intro_wmv"
          Margin="54,64,104,60"
          Source="/intro.wmv"
          Stretch="Fill"
          MediaEnded="md_ended_eve"
          MouseLeftButtonDown="pause_start_evn"/>
</Grid>

XAXM.CS Code

using System;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Ink;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;

namespace SilverlightApplication1
{
       public partial class MainPage : Grid
       {
              public MainPage()
              {
                     // Required to initialize variables
                     InitializeComponent();
              }

              private void md_ended_eve(object sender, System.Windows.RoutedEventArgs e)
              {
                     // TODO: Add event handler implementation here.
                     (intro_wmv).Stop();
                     (intro_wmv).Play();
              }
              private bool IsPaused=true;
              private void pause_start_evn(object sender, System.Windows.Input.MouseButtonEventArgs e)
              {
                     // TODO: Add event handler implementation here.
                     if(IsPaused)
                     {
                           (intro_wmv as MediaElement).Play();
                           IsPaused=false;
                     }
                     else
                     {
                           (intro_wmv as MediaElement).Pause();
                           IsPaused=true;
                     }
              }
       }
}

Now, that's all about the controlling of video playback in a Silverlight based application. Happy coding!

Silverlight 6 Hosting - HostForLIFE.eu :: How to Use ASP.NET to Create Silverlight Clock Apps

clock September 10, 2015 11:37 by author Rebecca

In this post, we will learn how to create Analog Clock completely from code behind using .NET Silverlight.

Step 1

Create a new project in Visual Studio and select "Silverlight Application".

Step 2

Open MainPage.xaml and add the following code:


    <UserControl x:Class="SilverlightAnalogClock.MainPage" 
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
        mc:Ignorable="d" 
        d:DesignHeight="300" d:DesignWidth="400"> 
     
        <Grid x:Name="LayoutRoot" Background="White"> 
            
        </Grid> 
    </UserControl>

HostForLIFE.eu Proudly Launches ASP.NET 4.6 Hosting

clock September 7, 2015 12:36 by author Peter

HostForLIFE.eu was established to cater to an underserved market in the hosting industry; web hosting for customers who want excellent service. HostForLIFE.eu – a cheap, constant uptime, excellent customer service, quality, and also reliable hosting provider in advanced Windows and ASP.NET technology. HostForLIFE.eu proudly announces the availability of the ASP.NET 4.6 hosting in their entire servers environment.

http://hostforlife.eu/img/logo_aspnet1.png

ASP.NET is Microsoft's dynamic website technology, enabling developers to create data-driven websites using the .NET platform and the latest version is 5 with lots of awesome features. ASP.NET 4.6 is a lean .NET stack for building modern web apps. Microsoft built it from the ground up to provide an optimized development framework for apps that are either deployed to the cloud or run on-premises. It consists of modular components with minimal overhead.

According to Microsoft officials, With the .NET Framework 4.6, you'll enjoy better performance with the new 64-bit "RyuJIT" JIT and high DPI support for WPF and Windows Forms. ASP.NET provides HTTP/2 support when running on Windows 10 and has more async task-returning APIs. There are also major updates in Visual Studio 2015 for .NET developers, many of which are built on top of the new Roslyn compiler framework. The .NET languages -- C# 6, F# 4, VB 14 -- have been updated, too.There are many great features in the .NET Framework 4.6. Some of these features, like RyuJIT and the latest GC updates, can provide improvements by just installing the .NET Framework 4.6.
