How to change text to speech language in Xamarin.Android C#

I wanted to make a text to speech application for a project and I used this as a reference: https://github.com/xamarin/monodroid-samples/tree/main/PlatformFeatures/TextToSpeech
However, whenever i open the app it always opens up the google tts service and I cannot change the language, and the spinner does not show any languages only "Default" is there a way to make this program not open up google tts service each time and making the language options available on the spinner? thanks so much!

Navigation- PopAsync() does not seem to work

I am creating a login form using Xamarin which accepts email, password fields.
After the user enters his details and clicks on login button, no alert box is displayed. It comes out of the app. Here is the code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data.SqlTypes;
using Xamarin.Forms;
using SQLite;
using System.IO;
namespace LoginPage.Views
{
public class AddDetails : ContentPage
{
private Entry _emailEntry;
private Entry _passwordEntry;
private Button _saveButton;
string _dbPath = Path.Combine(System.Environment.GetFolderPath(System.Environment.SpecialFolder.Personal), "myDB.db3");
public AddDetails()
{
this.Title = "Add Details";
StackLayout stackLayout = new StackLayout();
_emailEntry = new Entry();
_emailEntry.Keyboard = Keyboard.Text;
_emailEntry.Placeholder = "Email";
stackLayout.Children.Add(_emailEntry);
_passwordEntry = new Entry();
_passwordEntry.Keyboard = Keyboard.Text;
_passwordEntry.Placeholder = "Password";
stackLayout.Children.Add(_passwordEntry);
_saveButton = new Button();
_saveButton.Text = "Login User";
_saveButton.Clicked += _saveButton_Clicked;
stackLayout.Children.Add(_saveButton);
Content = stackLayout;
}
private async void _saveButton_Clicked(object Sender, EventArgs e)
{
var db = new SQLiteConnection(_dbPath);
db.CreateTable<User>();
var maxPk = db.Table<User>().OrderByDescending(c => c.Id).FirstOrDefault();
User user = new User()
{
Id = (maxPk == null ? 1 : Convert.ToInt32(maxPk.Id) +1),
Email = _emailEntry.Text,
Password = _passwordEntry.Text
};
db.Insert(user);
await DisplayAlert(null, user.Email + "Saved", "Ok");
await Navigation.PopAsync();
}
}
}
Login screen gets displayed, but no alert box which should say Email saved. Also, it comes out of the app abruptly

Have you set
MainPage = new NavigationPage (new Page1Xaml ());

C# GTK# MenuBar isn't displaying

I am trying to learn GTK# (obviously in C#). I am using Ubuntu and I compile with mono. I want to create a MenuBar and add some Menu, and MenuItem to it.
When I compile, all is OK but my menu isn't displaying.
public MainWindow() : base("LayText")
{
SetDefaultSize(800, 600);
SetPosition(WindowPosition.Center);
DeleteEvent += delegate { Application.Quit(); };
this.InitializeComponent();
ShowAll();
}
private void InitializeComponent()
{
this.m_new = new MenuItem("Nouveau fichier");
this.m_open = new MenuItem("Ouvrir fichier");
this.m_exit = new MenuItem("Quitter");
this.file = new Menu();
this.file.Append(this.m_new);
this.file.Append(this.m_open);
this.file.Append(this.m_exit);
this.menu_file = new MenuItem("Fichier");
this.menu_file.Submenu = this.file;
this.menu_bar = new MenuBar();
this.menu_bar.Append(this.menu_file);
this.vbox_princ = new VBox(false, 2);
this.vbox_princ.PackStart(this.menu_bar, false, false, 0);
this.Add(this.vbox_princ);
}
When I compile this code I am getting the window but without the menu I've set.
Screenshot of the window
Thanks for helping me.
Layce17

The following code (just a modification/completion or yours) works perfectly. I see you are using Ubuntu. Though I don't use it, I think it shows the menu bar in the top status bar. Have you checked that out?
using Gtk;
namespace Kk
{
class MainWindow: Gtk.Window {
public MainWindow() : base("LayText")
{
SetDefaultSize(800, 600);
SetPosition(WindowPosition.Center);
DeleteEvent += delegate { Application.Quit(); };
this.InitializeComponent();
ShowAll();
}
private void InitializeComponent()
{
var m_new = new MenuItem("Nouveau fichier");
var m_open = new MenuItem("Ouvrir fichier");
var m_exit = new MenuItem("Quitter");
var file = new Menu();
file.Append(m_new);
file.Append(m_open);
file.Append(m_exit);
var menu_file = new MenuItem("Fichier");
menu_file.Submenu = file;
var menu_bar = new MenuBar();
menu_bar.Append(menu_file);
var vbox_princ = new VBox(false, 2);
vbox_princ.PackStart(menu_bar, false, false, 0);
this.Add(vbox_princ);
}
public static void Main()
{
Application.Init();
new MainWindow();
Application.Run();
}
}
}
Hope this helps.

How to login to google accounts using awesomium in C#.net?

I'm learning Awesomium and following is the code in which I'm trying to login to https://accounts.google.com. I'm successfully able to set the login and password field values in the page, but not able to submit the login form, neither does the click works. Can anyone help me how to login?
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Awesomium.Core;
namespace Awesom
{
class Program1
{
public static void Main(String[] args)
{
Console.WriteLine("Started....");
WebView wv = WebCore.CreateWebView(1024, 600);
wv.Source = new Uri("https://accounts.google.com");
wv.LoadingFrameComplete += (s, e) =>
{
if (!e.IsMainFrame)
return;
dynamic document = (JSObject) wv.ExecuteJavascriptWithResult("document");
using(document)
{
//Works
var tbox = document.getElementById("Email");
tbox.value = "XXXXXXXX#gmail.com";
//Works
var pbox = document.getElementById("Passwd");
pbox.value = "**********";
//Doesnt work
var lform = document.getElementById("gaia_loginform");
lform.submit();
//Doesnt work
var sbox = document.getElementById("signIn");
sbox.click();
}
BitmapSurface surface = (BitmapSurface)wv.Surface;
surface.SaveToPNG("result.png", true);
WebCore.Shutdown();
};
WebCore.Run();
}
}
}
Result image:

It IS working, you're just taking the screenshot too early. You need to account for the second frame navigation, if you use .click().
public static void Main(String[] args)
{
Console.WriteLine("Started....");
WebView wv = WebCore.CreateWebView(1024, 600);
wv.Source = new Uri("https://accounts.google.com/");
FrameEventHandler handler = null;
handler = (s, e) =>
{
if (e.IsMainFrame)
{
// we have finished loading main page,
// let's unhook ourselves
wv.LoadingFrameComplete -= handler;
LoginAndTakeScreenShot(wv);
}
};
wv.LoadingFrameComplete += handler;
WebCore.Run();
}
private static void LoginAndTakeScreenShot(WebView wv)
{
dynamic document = (JSObject)wv.ExecuteJavascriptWithResult("document");
using (document)
{
//Works
var tbox = document.getElementById("Email");
tbox.value = "XXXXXXXX#gmail.com";
//Works
var pbox = document.getElementById("Passwd");
pbox.value = "**********";
FrameEventHandler handler = null;
handler = (sender, args) =>
{
if (args.IsMainFrame)
{
wv.LoadingFrameComplete -= handler;
BitmapSurface surface = (BitmapSurface)wv.Surface;
surface.SaveToPNG("result.png", true);
WebCore.Shutdown();
}
};
wv.LoadingFrameComplete += handler;
var sbox = document.getElementById("signIn");
sbox.click();
}
}

C# edit property of panel using run-time generated button

I'm a complete noob in C# programming. This is my problem: I have a form with a panel that is generated upon clicking button 1, the panel also containes a button (btnColor1) to change the backcolor of the panel. I would like to refer to the panel's backcolor in btnColor1, but I get the error "The name 'btnColor1' does not exist in the current context". How can I fix this?
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 TEST_APP_1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
Panel myPanel1 = new Panel();
myPanel1.Location = new System.Drawing.Point(100, 50);
myPanel1.Name = "Panel 1";
myPanel1.Size = new System.Drawing.Size(200, 100);
myPanel1.BackColor = Color.Red;
TextBox textBox1 = new TextBox();
textBox1.Location = new Point(10, 50);
textBox1.Text = "empty field";
textBox1.Size = new Size(150, 30);
Button btnColor1 = new Button();
btnColor1.Location = new Point(10, 10);
btnColor1.Text = "GOLD";
btnColor1.Size = new Size(100, 30);
btnColor1.Click += myButton1_Click;
myPanel1.Controls.Add(textBox1);
myPanel1.Controls.Add(btnColor1);
Controls.Add(myPanel1);
}
private void myButton1_Click(object sender, EventArgs e)
{
throw new NotImplementedException();
btnColor1.BackColor = Color.Gold;
}
}
}

btnColor1 is declared in the scope of the button1_Click method so does not exist as a variable to reference in your event handler. Change the event handler to this:
private void myButton1_Click(object sender, EventArgs e)
{
throw new NotImplementedException();
(sender as Button).BackColor = Color.Gold;
}

You can try to use the parent property of the button to access the panel and the form:
private void myButton1_Click(object sender, EventArgs e)
{
Button but = (sender as Button);
but.BackColor = Color.Gold;
// this changes the color of the panel
but.Parent.BackColor = Color.Gold;
// this changes the color of the form containing the panel
if (but.Parent.Parent != null)
{
but.Parent.Parent.BackColor = Color.Gold;
}
}
