    <p>I have tried to goole solutions for hours...</p> <p>I'm doing an app for windowsphone, which is used to show public transport details. I need to change values of WhereFrom and WhereTo and click submit in the tinyurl webpage and then scrape the info. If you can recommend any other way to do this, please tell it. I have also tried webclient, httpwebrequest, but their instructions and examples are way too complicated for me.</p> <p>I'm stuck with the error mentioned before and the selain.InvokeScript("eval"); line causes it. Even stranger is that I only got this error in this tinyurl website. eg when using www.bing.com site I have another error: 80020101 using the third Invokescript line.</p> <pre><code>using System.Net; using System.Windows; using System.Windows.Controls; using System.Windows.Documents; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Animation; using System.Windows.Shapes; using Microsoft.Phone.Controls; using System.Runtime.InteropServices; //COMException namespace PhoneApp5 { public partial class MainPage : PhoneApplicationPage { // Constructor public MainPage() { InitializeComponent(); //selain as WebBrowser.

    1. COI got tired with this solution and tried httpwebrequest,httpwebresponse and Html agility pack with much better results :). httpwebrequest is slightly more annoying to use but it works.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
