How to create Redirect URI OAuth2 in C# Console App with Dropbox API?

I've tried to create a Redirect URI, but seems that it is wrong. Actually, it's my first time trying to work with Dropbox API using .Net and I don't know many things.
As I said, I'm using Console Application in Visual Studio 2017. I wrote the code down below.
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
if(String.IsNullOrEmpty(Properties.Settings.Default.AccessToken))
{
this.GetAccessToken();
}
else
{
this.GetFiles();
}
}
private void GetAccessToken()
{
var login = new DropboxLogin("wbjcj6pa94berli", appKey, "https://www.dropbox.com/developers/apps/info/wbjcj6pa94berli", false, false);
login.Owner = this;
login.ShowDialog();
if (login.IsSuccessfully)
{
Properties.Settings.Default.AccessToken = login.AccessToken.Value;
Properties.Settings.Default.Save();
}
else
{
MessageBox.Show("Error...");
}
}
private void GetFiles()
{
}
}
I've created this Redirect URI in My App on Dropbox's site for Developers.
Redirect URI on Dropbox's WebPage:

I'm getting that MessageBox with "Error..." because, obviously, something is wrong.
Could any of you guys help me with this? Thanks a lot.

Is it possible to show DisplayAlert on startup (Xamarin.Forms)

In my mobile application (xamarin forms), I'm getting data from internet so it needs internet connection. Since I have a dictionary which I initialize in App.xaml.cs and I use data from internet, I need to check for internet connection. I have seen this question where OP asks for something similar, but the answer doesn't work for me since I need to check for internet connection whenever app launches, not after MainPage is launched. For example, Clash of Clans. Whenever the app launches, the app checks for internet connection and if there's no connection, it displays a alert to user repetitively until there's a connection.
using Xamarin.Forms;
using Xamarin.Forms.Xaml;
using System.Collections.Generic;
using HtmlAgilityPack;
using System.Text.RegularExpressions;
using System;
[assembly: XamlCompilation(XamlCompilationOptions.Compile)]
namespace Multi
{
public partial class App : Application
{
static GroupStage groupstage = new GroupStage();
public static HtmlWeb web = new HtmlWeb();
public static HtmlDocument doc = LoadUrlAndTestConnection();
//The reason why I have put a method is because I wanted to try if I can use try-catch to display alert, however this didn't work.
public static HtmlDocument LoadUrlAndTestConnection()
{
bool con = true;
while (con)
{
try
{
doc = web.Load(someURL);
}
catch (Exception ex)
{
var sth = new ErrorPage();
sth.InternetErrorDisplay();
con = true;
continue;
}
con = false;
}
return docSK;
}
public static Dictionary<string, Country> _countries = new Dictionary<string, Country>
{
["Australia"] = new Country(1, "Australia", false, "AU", "ausFlag.png", 3, groupstage, GetScore("Australia", 3)),
public static string[] GetScore(string name, int GroupID)
{
//Gets the score data from internet
}
public App()
{
InitializeComponent();
TwitchClass.MainAsync().Wait();
MainPage = new OpeningPage();
}
protected override void OnStart()
{
}
protected override void OnSleep()
{
}
protected override void OnResume()
{
}
}
}
//GetScore method requires internet connection as it gets the score data from internet.
and the InternetErrorDisplay method is,
public void InternetErrorDisplay() => DisplayAlert("Connection Error", "Could not detect internet connection. This application requires access to internet.", "Retry");
Is it possible to have this behaviour in xamarin forms app? How can I achieve it?

Yes, why should it not be possible?
Here is an example which uses async/await
using System;
using Xamarin.Forms;
using Xamarin.Forms.Xaml;
using System.Threading.Tasks;
[assembly: XamlCompilation(XamlCompilationOptions.Compile)]
namespace LoadingSample
{
public partial class App : Application
{
public App()
{
InitializeComponent();
//MainPage = new MainPage();
}
protected override async void OnStart()
{
// shows Loading...
MainPage = new LoadPage();
await Task.Yield();
// Handle when your app starts
// Just a simulation with 10 tries to get the data
for (int i = 0; i < 10; i++)
{
await Task.Delay(500);
// await internet_service.InitializeAsync();
await MainPage.DisplayAlert(
"Connection Error",
"Unable to connect with the server. Check your internet connection and try again",
"Try again");
}
await Task.Delay(2000);
// after loading is complete show the real page
MainPage = new MainPage();
}
protected override void OnSleep()
{
// Handle when your app sleeps
}
protected override void OnResume()
{
// Handle when your app resumes
}
}
}

Adding EventFiringWebDriver to Selenium Framework

I need help with expanding my already build Selenium framework with WebDriver. I want to add eventHandlers that use EventFiringWebDriver on top of my code to add event for each action triggered by WebDriver for logging purposes.
To begin with, I will try to clearly present code flow.
Test starts...
Step 1. CspTestBase
public class CspTestBase : CommonElements
{
[BeforeScenario]
public void Init()
{
Initialize(); <- Code to init driver.
// more code here.
LoginPage.Goto();
LoginPage.LoginAs(TestConfig.Username).WithPassword(TestConfig.Password).Login();
}
[AfterScenario]
public void CleanUp()
{
Close();
}
When it jumps to Init method. This class holds all methods that directly require WebDriver instance.
public static class Driver
{
public static IWebDriver Instance { get; private set; }
public static void Initialize()
{
Instance = new TestDriverFactory().CreateDriver(); <- Next step
Instance.Manage().Timeouts().ImplicitlyWait(new TimeSpan(0, 0, 30));
Instance.Manage().Cookies.DeleteAllCookies();
//Instance.Manage().Window.Maximize();
}
Then when WebDriver Instance is created:
public class TestDriverFactory
{
public IWebDriver CreateDriver()
{
return new TestBase().Create(
new LocalDriverConfig(
TestConfig.Browser));
}
}
And when it finally comes to creating actual driver:
public class TestBase
{
private static IWebDriver _driver;
//string env;
private DesiredCapabilities _capabilities;
public IWebDriver Create(LocalDriverConfig config)
{
switch (config.Browser)
{
case "Chrome":
_driver = new ChromeDriver(#"C:\Utilities");
break;
case "Firefox":
SetFirefoxCapabilities();
//_driver = new FirefoxDriver(_capabilities);
break;
...
private void SetFirefoxCapabilities()
{
...
_capabilities = DesiredCapabilities.Firefox();
//FirefoxOptions options = new FirefoxOptions();
//options.SetLoggingPreference(LogType.Browser, LogLevel.Warning);
_capabilities.SetCapability(FirefoxDriver.ProfileCapabilityName, profile);
//capabilities.SetCapability(FirefoxDriver.ProfileCapabilityName, options);
EventFiringWebDriver firingDriver = new EventFiringWebDriver(new FirefoxDriver(binary, profile, TimeSpan.FromSeconds(60)));
// copy the profile for ommiting duplicate references
firingDriver.ExceptionThrown += firingDriver_TakeScreenshotOnException;
_driver = firingDriver;
}
private void firingDriver_TakeScreenshotOnException(object sender, WebDriverExceptionEventArgs e)
{
TakeScreenshot();
}
As you can see, I'm using EventFiringWebDriver already but I want to have it done properly to save me as much work as possible.
I did some reading and looked up solutions but these were simple or in Java. Any help will be much appreciated.

C# Web Traffic Listener

I am trying to write a simple c# console application which shows the accessed websites (sort of proxy server) . I understood that the right approach would be using .Net Sockets and TCP Listeners. However, I tried some code samples and I can get working none of them.
Any suggestions would be great!

You can use FiddlerCore
public class HttpProxy : IDisposable
{
public HttpProxy()
{
Fiddler.FiddlerApplication.BeforeRequest += FiddlerApplication_BeforeRequest;
Fiddler.FiddlerApplication.Startup(8888, true, true);
}
void FiddlerApplication_BeforeRequest(Fiddler.Session oSession)
{
Console.WriteLine(String.Format("REQ: {0}", oSession.url));
}
public void Dispose()
{
Fiddler.FiddlerApplication.Shutdown();
}
}
static void Main(string[] Args)
{
var p = new HttpProxy();
Console.ReadLine();
p.Dispose();
}

Handling Server-side RtmpConnection.Invoke() when connecting with NetConnection as a client using FluorineFx

I am trying to create a basic console app in order to stress test our FluorineFx based flash remoting server.
I can connect fine but the server method I am calling invokes this client-side function:
connection.Invoke("onServerDataPush", new string[] { "someParam", "anotherParam" });
I am struggling to find out how I can expose this method to the connection. The NetConnection.Call() method allow you to pass in a callback but the result of this is always null and the NetConnection call fails with the following error:
Could not find a suitable method with name onServerDataPush
Here is my client-side code:
class Program
{
private NetConnection _netConnection;
static void Main(string[] args)
{
var program = new Program();
program.Connect();
Console.ReadLine();
}
public void Connect()
{
_netConnection = new NetConnection();
_netConnection.ObjectEncoding = ObjectEncoding.AMF3;
_netConnection.OnConnect += netConnection_OnConnect;
_netConnection.NetStatus += netConnection_NetStatus;
_netConnection.Connect("rtmp://localhost:1935/MyApplication");
}
void netConnection_OnConnect(object sender, EventArgs e)
{
var responder = new Responder<object>(x =>
{
var test = x;
});
//The NetConnection object is connected now
_netConnection.Call("MyServerMethod", responder, "someParameter");
}
void netConnection_NetStatus(object sender, NetStatusEventArgs e)
{
string level = e.Info["level"] as string;
}
}

Debugging through RtmpClient line 308 finally allowed me to solve this.
You must set the NetConnection.Client property to the class that contains a method of the same signature as the one being invoked by the server (in my case this as the method is in the Program class).
public void onServerDataPush(string type, string json)
{
}
FluorineFx then calls the method using reflection.
