This is for a Desktop C# app in Visual Studio 2012.
I need to use a WebBrowser control in C# to log into a Windows Live instance, getting the control to open the page is nothing, but signing in is causing me a headache.
I've tried about 4 different suggestions gleaned from Google, but I'm not getting logged in properly.
This is what I've got:
//FORM1 code
//Added reference to 'Microsoft Internet Controls'
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace WindowsFormsApplication3
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
webBrowser1.Url = new Uri("http://digitbot.com/live/");
}
SHDocVw.WebBrowser nativeBrowser;
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
nativeBrowser = (SHDocVw.WebBrowser)webBrowser1.ActiveXInstance;
nativeBrowser.NewWindow2 += nativeBrowser_NewWindow2;
}
protected override void OnFormClosing(FormClosingEventArgs e)
{
nativeBrowser.NewWindow2 -= nativeBrowser_NewWindow2;
base.OnFormClosing(e);
}
void nativeBrowser_NewWindow2(ref object ppDisp, ref bool Cancel)
{
var popup = new Form2();
popup.Show(this);
ppDisp = popup.Browser.ActiveXInstance;
}
}
}
//FORM2 code
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace WindowsFormsApplication3
{
public partial class Form2 : Form
{
public Form2()
{
InitializeComponent();
}
public WebBrowser Browser
{
get { return webBrowser1; }
}
}
}
This launches the login pop-up in the second window, but somehow it never seems to complete the process.
Following the link in the code above in a browser should get you logged in and should show raw JSON of calendar events followed by a profile picture. I need to get the same result in the WebBrowser control.
Any help would be great, I'm stuck.
Never got my initial approach to work, so I switched to using a WebClient and Browser with REST server-side since I needed to do stuff with the user logged out.
This is the basic setup on the C# Windows 8 side with WPF:
static string client_id = "your-client-id";
static string client_secret = "your-client-secret";
static string accessTokenUrl =
String.Format(@"https://login.live.com/oauth20_token.srf?client_id={0}&client" +
@"_secret={1}&redirect_uri=https://login.live.com/oauth20_desktop.srf&grant_type" +
@"=authorization_code&code=", client_id, client_secret);
static string apiUrl = @"https://apis.live.net/v5.0/";
public Dictionary<string, string> tokenData = new Dictionary<string, string>();
This is the bulk of the code in my main window:
private void getAccessToken()
{
if (App.Current.Properties.Contains("auth_code"))
{
makeAccessTokenRequest(accessTokenUrl + App.Current.Properties["auth_code"]);
}
}
private void makeAccessTokenRequest(string requestUrl)
{
try
{
WebClient wc = new WebClient();
wc.DownloadStringCompleted += new DownloadStringCompletedEventHandler(accessToken_DownloadStringCompleted);
wc.DownloadStringAsync(new Uri(requestUrl));
lError.Content = "";
}
catch (Exception ex)
{
lError.Content = "There has been an internet connection error.";
}
}
void accessToken_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
{
tokenData = deserializeJson(e.Result);
if (tokenData.ContainsKey("access_token"))
{
App.Current.Properties.Add("access_token", tokenData["access_token"]);
App.Current.Properties.Add("refresh_token", tokenData["refresh_token"]);
getUserInfo();
}
}
private Dictionary<string, string> deserializeJson(string json)
{
var jss = new JavaScriptSerializer();
var d = jss.Deserialize<Dictionary<string, string>>(json);
return d;
}
private void getUserInfo()
{
if (App.Current.Properties.Contains("access_token"))
{
try
{
makeApiRequest(apiUrl + "me?access_token=" + App.Current.Properties["access_token"]);
lError.Content = "";
}
catch (Exception ex)
{
lError.Content = "There has been an internet connection error.";
}
}
}
private void makeApiRequest(string requestUrl)
{
try
{
WebClient wc = new WebClient();
wc.DownloadStringCompleted += new DownloadStringCompletedEventHandler(client_DownloadStringCompleted);
wc.DownloadStringAsync(new Uri(requestUrl));
lError.Content = "";
}
catch (Exception ex)
{
lError.Content = "There has been an internet connection error.";
}
}
void client_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
{
changeView(e.Result);
}
private void changeView(string result)
{
string imgUrl = apiUrl + "me/picture?access_token=" + App.Current.Properties["access_token"];
imgUser.Source = new BitmapImage(new Uri(imgUrl, UriKind.RelativeOrAbsolute));
String code = "" + App.Current.Properties["refresh_token"];
String auth = "" + App.Current.Properties["access_token"];
}
void browser_Closed(object sender, EventArgs e)
{
try
{
getAccessToken();
lError.Content = "";
}
catch (Exception ex)
{
lError.Content = "There has been an internet connection error.";
}
}
The Windows Live authorization will then happen in this browser and go away once we're logged in.
XAML for the browser:
<Window x:Class="WpfApplication3.BrowserWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Sign In" Height="460" Width="423.881"
ShowInTaskbar="False" WindowStartupLocation="CenterScreen">
<Grid>
<WebBrowser Height="419" HorizontalAlignment="Left"
Name="webBrowser" VerticalAlignment="Top"
Width="406" LoadCompleted="webBrowser_LoadCompleted" />
</Grid>
</Window>
And here's the browser code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Shapes;
using System.Text.RegularExpressions;
namespace WpfApplication3
{
public partial class BrowserWindow : Window
{
static string scope = "wl.signin wl.calendars wl.offline_access wl.contacts_calendars";
static string client_id = "your-client-id";
static Uri signInUrl = new Uri(String.Format(@"https://login.live.com/oauth20" +
@"_authorize.srf?client_id={0}&redirect_uri=https://login.live.com/" +
@"oauth20_desktop.srf&response_type=code&scope={1}", client_id, scope));
MainWindow mainWindow = new MainWindow();
public BrowserWindow()
{
InitializeComponent();
webBrowser.Navigate(signInUrl);
}
private void webBrowser_LoadCompleted(object sender, System.Windows.Navigation.NavigationEventArgs e)
{
if (e.Uri.AbsoluteUri.Contains("code="))
{
if (App.Current.Properties.Contains("auth_code"))
{
App.Current.Properties.Clear();
}
string auth_code = Regex.Split(e.Uri.AbsoluteUri, "code=")[1];
App.Current.Properties.Add("auth_code", auth_code);
this.Close();
}
}
}
}
