Windows AdDuplex NuGet support

The best way to integrate AdDuplex into your project is through NuGet system, and not Visual Studio Gallery on MSDN.

This prevent Visual Studio Designer from Unhandled Exceptions.

So, if you already added Reference on installed AdDuplex support from Visual Studio Gallery on MSDN, remove it, and add corresponding NuGet packages for AdDuplex support.

Then in Windows 10 Universal project:

Add a namespace declaration to your page

Add an AdControl to your page:
< adduplex:AdControl AdUnitId="xxxxxx" AppKey="xxxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" />

Then in Windows 8.1 Store project:

Add a namespace declaration to your page:

Add an AdControl to your page:
< adduplex:AdControl AdUnitId="xxxxxx" AppKey="xxxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" />

Then in Windows 8.1 Phone project:

Add a namespace declaration to your page:

Add an AdControl to your page:
< adduplex:AdControl AdUnitId="xxxxxx" AppKey="xxxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" />

Happy coding !

Parse News RSS 2.0 image in C#

If you want to parse News RSS 2.0 image from link, for example > http://codecanyon.net/feeds/new-codecanyon-items.atom

The following code can be used to match all img src in the source text and to populate list with value of src attribute.

private static IEnumerable<string> GetImagesInHTMLString(string htmlString)
            var images = new List<string>();
            const string pattern = Imgpattern;
            var rgx = new Regex(pattern, RegexOptions.IgnoreCase);
            MatchCollection matches = rgx.Matches(htmlString);

            for (int i = 0, l = matches.Count; i < l; i++)
                if (matches[i].Value.Contains(".jpg") || matches[i].Value.Contains(".png"))
                    var ms = Regex.Matches(matches[i].Value, Urlpattern);
                    if (ms.Count > 0)
                        if (!string.IsNullOrEmpty(ms[0].Value))
                            images.Add(ms[0].Value.Replace("\"", string.Empty));

            return images;

Decompiled C# Library : AppStudio.Common.dll

Wonderfull Microsoft Windows AppStudio on adress http://appstudio.windows.com generate Universal Applications for Windows Phone and Windows Store in C# - online.

Downloaded generated source code use closed library AppStudio.Common.dll, which breaks further portability.

Fortunately, the only items being used from this library are the BindableBase, BindableSchemaBase, and IDataSource. 

So I recreated these files in the directly, removing the AppStudio.Common.dll reference entirely from both the  Windows projects.

Here’s the code for the BindableBase:

using System;
using System.Collectionus.Generic;
using System.ComponentModel;
using System.Runtime.CompilerServices;

namespace SoftLabPro.Data
{ public abstract class BindableBase : INotifyPropertyChanged
    public event PropertyChangedEventHandler PropertyChanged;
    protected BindableBase()
    public virtual void Initialize(IDictionary<string, string> parameters)
    protected void OnPropertyChanged(string propertyName = null)
        PropertyChangedEventHandler propertyChanged = this.PropertyChanged;
        if (propertyChanged != null)
                propertyChanged(this, new PropertyChangedEventArgs(propertyName));
    protected bool SetProperty<T>(ref T storage, T value, [CallerMemberName] string propertyName = null)
        if (object.Equals((T)storage, value))
            return false;
        storage = value;
        return true;

Here is BindableSchemaBase:

using System;
using System.Runtime.CompilerServices;
using System.Text;

namespace SoftLabPro.Data
{ public abstract class BindableSchemaBase : BindableBase
    public BindableSchemaBase()
        this.Id = Guid.NewGuid().ToString();
    public abstract string GetValue(string propertyName);
    public virtual string GetValues(params string[] propertyNames)
        StringBuilder builder = new StringBuilder();
        foreach (string str in propertyNames)
            builder.AppendLine((this.GetValue(str) ?? string.Empty).ToString());
        return builder.ToString();
    public abstract string DefaultContent { get; }
    public abstract string DefaultImageUrl { get; }
    public abstract string DefaultSummary { get; }
    public abstract string DefaultTitle { get; }
    public string Id { get; set; }

And finally IDataSource:

using System.Collections.Generic;

using System.Threading.Tasks;

namespace SoftLabPro.Data

    public interface IDataSource<T> where T : BindableSchemaBase

    Task<IEnumerable<T>> LoadData();
    Task<IEnumerable<T>> Refresh();

Parse Google News RSS image in C#

If you want to parse Google News RSS image from link, for example > http://news.google.com/news?hl=us&q=android&output=rss

The following code can be used to match all img src in the source text and to populate list with value of src attribute.

private static IEnumerable<string> GetImagesInGoogleNewsString(string htmlString)
            List<string> imgSrcs = new List<string>();
            //const string pattern = Imgpattern;
            //var rgx = new Regex(pattern, RegexOptions.IgnoreCase);
            var imgSrcMatches = System.Text.RegularExpressions.Regex.Matches(htmlString, string.Format(@"<\s*img\s*src\s*=\s*{0}\s*([^{0}]+)\s*{0}", "\""),
               RegexOptions.CultureInvariant | RegexOptions.IgnoreCase | 

            foreach (Match match in imgSrcMatches)
                imgSrcs.Add("http:" + match.Groups[1].Value);

            return imgSrcs;
