I am having issues with Authentication in my Windows Phone 7 app using Facebook SDK .net
here is the authentication part
var facebookClient = new FacebookClient();
facebookClient.AppId = FacebookAppId;
facebookClient.AppSecret = FacebookSecret;
var authUrl = facebookClient.GetLoginUrl(new
{
client_id = FacebookAppId,
client_secret = FacebookSecret,
scope = "publish_stream",
response_type = "token",
display = "touch",
redirect_uri = "https://www.facebook.com/connect/login_success.html"
});
browser.Navigate(authUrl);
So the browser screens seem to work fine, login screen shows and then the permissions screens show. When I press OK on the last permission screen I just get a white screen. In fact I have been staring at this white screen for 10mins now.
Any ideas?
Here is the Browser.Navigated event handler. I have commented where I have put breakpoints
async void browser_Navigated(object sender, System.Windows.Navigation.NavigationEventArgs e)
{
FacebookOAuthResult result;
var facebookClient = new FacebookClient(); // Put break point here to make sure the event is handled
if(facebookClient.TryParseOAuthCallbackUrl(e.Uri, out result))
{
if (result.IsSuccess) // Put break point here to check result but its never reached
{
Logging.WriteLine("Authentication was a success!");
Classes.Facebook.Instance.AccessToken = result.AccessToken;
CreateFacebookPost();
}
else
{
MessageBox.Show(string.Format("Error: {0}\nReason:{1}", result.ErrorDescription, result.ErrorReason), "Authentication Error", MessageBoxButton.OK);
Logging.WriteLine("Authentication Failed");
Logging.WriteLine(string.Format("Error: {0}\nReason:{1}", result.ErrorDescription, result.ErrorReason));
}
browser.Visibility = System.Windows.Visibility.Collapsed;
browser.Navigated -= browser_Navigated;
}
}
EDIT 1:
Just some more info. I know the authentication (from Facebooks view) is a success as I can now see the app on my Facebook. Also, if I push back on the phone to go to previous screen of the app and then go back into the facebook section it shows everything is ok and I can make posts.
EDIT 2:
Using very similar code, this works fine in a Windows Phone 8 app. I have compared the 2 and can't seen any difference.
Looks like I have found the solution. You have to set IsScriptedEnabled=True on the WebBrowser control. By default it is false.

I want a phone number from a TextView to call the phone number when clicked:
The issue I am facing is that when clicking the link, the message app is opening instead. I tried the following code in iOS 12 and it worked as expected, but when I try on iOS 13 and 14, the message app opens instead of making a call using the "phone dialer app".
Tentative 1:
textView.Editable = false;
textView.DataDetectorTypes = UIDataDetectorType.PhoneNumber;
Tentative 2:
var phoneNumberLink = new Dictionary<string, string>(){ { "(855) 757-7328","tel:8557577328" } }
textView.Editable = false;
textView.SetAttributedTextForLinks("Please call us at (855) 757-7328", phoneNumberLink);
Actually, telpromt://0123456789 also did not work. I had to intercept the interaction with URL, the recommended ShouldInteractWithUrl did not work (ShouldInteractWithUrl was not triggered or called), so I had to use AllowUrlInteraction instead. The code looked something like this:
var description = new KiteEmbeddedLinkTextView()
{
Editable = false,
DataDetectorTypes = UIDataDetectorType.PhoneNumber,
Text = message.MessageText
};
description.AllowUrlInteraction += AllowUrlInteraction;
private bool AllowUrlInteraction(UITextView textView, NSUrl url, NSRange characterRange, UITextItemInteraction interaction)
{
UIApplication.SharedApplication.OpenUrl(url);
return false;
}
For some reason none of the previous options worked for me, besides this one.

How to intercept click on link in UITextView?
As mentioned https://forums.xamarin.com/discussion/33798/open-phone-dialer-from-app
The correct way to open the dialer is
telprompt://0123456789
Make sure that there are no spaces.
I have two instances of the ChromiumWebBrowser in my WinForms project (Visual Studio 2012). My goal is to have the second browser instance "copy" the behavior of the user input in the first browser instance. I can successfully retrieve the input from the first browser, and I managed to hook up Selenium in the project as well.
However, I'm having one issue. Whenever Selenium sends its commands, the first browser is the one that responds to them. For the life of me, I can't seem to figure out how to make the second browser respond. Whenever I completely remove the first browser, the second one starts responding correctly, but adding the first browser again will make only have the first browser use the Selenium commands. I even tried to switch out the moments the browsers are added to the form, but to no avail: whenever there are two available, the wrong one is responsive.
Relevant code:
public BrowserManager(Controller controller, string startingUrl)
{
_controller = controller;
var settings = new CefSettings { RemoteDebuggingPort = 9515 };
Cef.Initialize(settings);
// Input browser
inputBrowser = new ChromiumWebBrowser(startingUrl);
var obj = new XPathHelper(this);
inputBrowser.RegisterJsObject("bound", obj); //Standard object registration
inputBrowser.FrameLoadEnd += obj.OnFrameLoadEnd;
// Output browser
var browserSettings = new BrowserSettings();
var requestContextSettings = new RequestContextSettings { CachePath = "" };
var requestContext = new RequestContext(requestContextSettings);
outputBrowser = new ChromiumWebBrowser(startingUrl);
outputBrowser.RequestContext = requestContext;
outputBrowser.AddressChanged += InitializeOutputBrowser;
outputBrowser.Enabled = false;
outputBrowser.Name = "outputBrowser";
}
The selenium part:
public class SeleniumHelper
{
public SeleniumHelper()
{
DoWorkAsync();
}
private Task DoWorkAsync()
{
Task.Run(() =>
{
string chromeDriverDir = #"ActionRecorder\bin\x64\Debug\Drivers";
var chromeDriverService = ChromeDriverService.CreateDefaultService(chromeDriverDir);
chromeDriverService.HideCommandPromptWindow = true;
ChromeOptions options = new ChromeOptions();
options.BinaryLocation = #"ActionRecorder\bin\x64\Debug\ActionRecorder.exe";
options.DebuggerAddress = "127.0.0.1:9515";
options.AddArguments("--enable-logging");
using (IWebDriver driver = new OpenQA.Selenium.Chrome.ChromeDriver(chromeDriverService, options))
{
driver.Navigate().GoToUrl("http://www.google.com");
var query = driver.FindElement(By.Name("q"));
query.SendKeys("A google search test");
query.Submit();
}
});
return null;
}
}
And finally, a screenshot for some visualization:
Some help with the issue would be very much appreciated. If i missed some crucial info, feel free to ask for it. Thanks in advance!

The behavior is correct. You have one debug address and you can only have one debug address for CEF. Which means when you use Selenium it is only seeing one browser.
By default Selenium will send an command to current active Tab or Window. Now in your case you have multiple Chrome view embedded, but they are technically Chrome Tab/Windows which you have placed on the same form.
So if you are in luck below code in should be able to move you to the Window you are interested in
driver.SwitchTo().Window(driver.WindowHandles.Last());
See if it works. If it doesn't then your only other workaround would be to change the order of Adding ChromiumWebBrowser and that should reverse the window it works on.
Below are some important threads that you should read from top to bottom. Very relevant to your issue/request

I am attempting to help a user log into their account using a custom WebBrowser control. I am trying to set the value of an input tag to the players username using the WebBrowser's InvokeScript function. However, my current solution is doing nothing but rendering a blank white page.
My current code looks like this (web is the name for my WebBrowser control):
web.Navigate(CurrentURL, null, #"<script type='text/javascript'>
function SetPlayerData(input) {
username.value = input;
return true;
}
</script>");
web.Navigated += (o, e) =>
{
web.IsScriptEnabled = true;
web.InvokeScript("SetPlayerData", #"test");
};
As mentioned, this does not work right now. I am attempting to do this on Windows Phone so a number of the example's I have found here and in other places will not work as I do not have access to the same functions.
How would I perform this successfully?
EDIT: Perhaps I was not clear, but I am working with Windows Phone, which has a limited API available meaning I do not have access to the Document property and a number of other functions. I do have access to InvokeScript, but not much more.
webBrowser1.Document.GetElementById("navbar_username").InnerText ="Tester";
webBrowser1.Document.GetElementById("navbar_password").InnerText = "xxxxxxxxxxx";
foreach (HtmlElement HtmlElement1 in webBrowser1.Document.Body.All)
{
if (HtmlElement1.GetAttribute("value") == "Log in")
{
HtmlElement1.InvokeMember("click");
break;
}
}

It's been along time since this question is posted but I think I'll post an answer to this so that it will help some one who came across the same situation
try
{
webBrowser1.Document.GetElementById("navbar_username").SetAttribute("value", "your user");
webBrowser1.Document.GetElementById("navbar_password").SetAttribute("value", "your pass");
webBrowser1.Document.GetElementById("Log in").InvokeMember("click");
}
catch { }
I have tried to find answers on following questions for at least one hour but with no success.
I have WPF project (C#) and I have webBrowser control to navigate to my Facebook page http://www.facebook.com/TennisHelper and I want to do next few things:
I want to avoid login by creating user settings in my application which will contain email and password, but I don't know how to do that with C# Facebook SDK,
I want to make able for my user to post textual posts on that page via textBox control,
I want to make able for my user to post photos from his computer directly to that page, but with not creating new albums. Just to post image on page wall.
I was searching Google for all those problems but with no success
Let me know actually what is your requirement.I think your first requirement is to add a facebook login(or register with facebook page) button in your Website login page.
step1:You need to register a new facebook application on facebook.
step 2:install facebook c# sdk .You can either download the zip file manually or install it using nuget.I recommend the second option.I am using c# sdk 5.4.1 What is nuget? How to install a package using nuget?
step 3:Now you can add name space facebook to the page
step 4:Insert a login button(simply a button with text login) in login page(say login.aspx).Let it be button1
step 5:On click button redire to another page (let login1.aspx)
here is a sample code for login 1
using Facebook;//
FacebookOAuthClient fb = new FacebookOAuthClient();
UriBuilder red = new UriBuilder("www.example.com/Login1.aspx");
protected void Page_Load(object sender, EventArgs e)
{
string appid = "{your app id}";
string appsecret = "{your app secret}";
string permissions = "publish_stream";
if(Request.QueryString["code"] == null)
{
try
{
Response.Redirect("https://www.facebook.com/dialog/oauth?client_id=" + appid + "&redirect_uri=" + red.Uri.ToString() + "&scope=" + permissions +"&state=djfjfdjj");
}
catch (Exception b)
{
Label1.Text = b.ToString();
}
}
else
{
try
{
FacebookOAuthClient cl = new FacebookOAuthClient();
cl.RedirectUri = red.Uri;
cl.AppId = appid;
cl.AppSecret = appsecret;
dynamic result = cl.ExchangeCodeForAccessToken(Request.QueryString["code"]);
Label1.Text = Convert.ToString(result);
if (result["access_token"] != null)
{
Session["access_token"] = result["access_token"].ToString();//Now you have access token
Response.Redirect("Welcome.aspx");//replace welcome.aspx
}
else
{
Label1.Text = "Unable to authenticate\n Please try again later";
}
}
catch(Exception b)
{
Label1.Text = b.ToString();
}
}
}
Now you have access token saved in session.
for getting basic information of the client
dynamic me=fb.Get("\me");
it in cludes first name, last name ,email address,location,image url etc. of the current user.Now you can use this e-mail or name to verify your user or register new user etc.(its up to you ).
posting on that page is possible but diffiult How can I use the Facebook C# SDK to post on Facebook Pages
You should register an application on Facebook in order to use Facebook log in.navigate to
http://developers.facebook.com
create an appllication.You will get an application id and application secret.Use it as appid,appsecret
I have pages that I admin in the Facebook and I want to share a link(not post) from that page using Facebook C# SDK. How can I do that? For clarify question, Facebook pages has link button that you can share link with page's picture.
Simply facebookclient.Post("me/feed",parameters);
For the parameters see https://developers.facebook.com/docs/reference/api/post/
messagePost["message"] = message;
messagePost["caption"] = caption;
messagePost["description"] = descr;
messagePost["link"] = "http://xxx";
FacebookClient fbClient = new FacebookClient(FacebookAdminToken); //users have to accept your app
dynamic fbAccounts = fbClient.Get("/" + FacebookAdminId + "/accounts");
if (pageID != null)
{
foreach (dynamic account in fbAccounts.data)
{
if (account.id == pageID)
{
messagePost["access_token"] = account.access_token;
break;
}
}
dynamic publishedResponse = fbClient.Post("/" + pageID + "/links", messagePost);
message.Success = true;
}
Hope his helps.
there is two majour problems with my solution:
1) my FacebookAdmintoken was created using the soon to be deprecated offline_status. there currently is no way for the access_token to stay alive otherwise. Facebook claims it does, but it just doesn't work.
2) there is a bug in the facebook API. when you use post('/id/LINKS') you cannot specify the picture (FB chooses a random pic from the site) and using post('/id/FEED') people can see the result, but they cannot SHARE it.
Seriously FB, get your act together!!!!!
