target frame detached Selenium c#

I wrote a class to automaticly translate text with selenium. When the translate button is pushed the page doesn't reload completly, I assume this happens with Javascript. I added a wait function to wait until the text shows up. However in 3 of the 10 generated translations I get the next error at line 30:
OpenQA.Selenium.WebDriverException: 'target frame detached (Session info: chrome=102.0.5005.115)'
Any solutions to fix it? thanks in advance!

OpenQA.Selenium.NoSuchElementException was unhandled + C# + Another Website

I am new to selenium, currently exploring on how it works. Started using it for ASP.NET application, i am using C# Selenium driver, IE Driver server ( 32 bit as it's faster than 64 bit)
I navigated to a application there I am clicking a link which should take me to ANOTHER WEBSITE where I have to find a textbox and clear it and enter some text (SendKeys) and then click a button.
When it goes to a another website from main website, It's unable to find the element ( I tried using by.ID and by.Name). I made sure element is available on the webpage. As recommened I used ImplicitlyWait but no luck, tried thread.sleep() no lucK.. Does the test needs to be on the same website which launched initially ?.. Below is my code snippet.. Please help me..
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using OpenQA.Selenium;
using OpenQA.Selenium.IE;
using OpenQA.Selenium.Support.UI;
using System.Threading;
namespace mySelenium
{
class Program
{
private static void Main(string[] args)
{
IWebDriver driver = new InternetExplorerDriver(#"C:\Users\msbyuva\Downloads\IEDriverServer_Win32_2.45.0\");
driver.Manage().Timeouts().ImplicitlyWait(TimeSpan.FromSeconds(10));
driver.Navigate().GoToUrl("http://MyorgName.org/Apps/Sites/2015/login.aspx");
IWebElement userNameTxtBox = driver.FindElement(By.Id("ContentPlaceHolder1_Login1_UserName"));
userNameTxtBox.SendKeys("MSBYUVA");
IWebElement passwordTxtBox = driver.FindElement(By.Id("ContentPlaceHolder1_Login1_Password"));
passwordTxtBox.SendKeys("1234");
var myButton = driver.FindElement(By.Id("ContentPlaceHolder1_Login1_LoginButton"));
myButton.Click();
var EMailLink = driver.FindElement(By.LinkText("Email Testing Link"));
EMailLink .Click();
//Thread.Sleep(10000);
// -- HERE IT IS THROWING ERROR (ANOTHER WEBSITE AFTER CLICKING HYPERLINK)
var toEmailAddress = driver.FindElement(By.Name("ctl00$ContentPlaceHolder1$txtTo"));
toEmailAddress.Clear();
toEmailAddress.SendKeys("msbyuva#gmail.com");
var chkEmailAttachment = driver.FindElement(By.Name("ctl00$ContentPlaceHolder1$ChkAttachMent"));
chkEmailAttachment.Click();
var sendEmailButton = driver.FindElement(By.Id("ctl00_ContentPlaceHolder1_BtnSend"));
sendEmailButton.Click();
}
}
}

You need to switchTo newly opened window and set focus to it in order to send any commands to it
string currentHandle = driver.CurrentWindowHandle;
driver.SwitchTo().Window(driver.WindowHandles.ToList().Last());
After you done with newly opened window do(as need)
driver.Close();
driver.SwitchTo().Window(currentHandle );
More perfectly use PopupWindowFinder class
string currentHandle = driver.CurrentWindowHandle;
PopupWindowFinder popUpWindow = new PopupWindowFinder(driver);
string popupWindowHandle = popUpWindow.Click(EMailLink );
driver.SwitchTo().Window(popupWindowHandle);
//then do the email stuff
var toEmailAddress = driver.FindElement(By.Name("ctl00$ContentPlaceHolder1$txtTo"));
toEmailAddress.Clear();
toEmailAddress.SendKeys("msbyuva#gmail.com");
var chkEmailAttachment = driver.FindElement(By.Name("ctl00$ContentPlaceHolder1$ChkAttachMent"));
chkEmailAttachment.Click();
var sendEmailButton = driver.FindElement(By.Id("ctl00_ContentPlaceHolder1_BtnSend"));
sendEmailButton.Click();
}
}
}
//closing pop up window
driver.Close();
driver.SwitchToWindow(currentHandle);

Screen Capture in C# using HtmlAgilityPack

Due to the lack of proper documentation, I'm not sure if HtmlAgilityPack supports screen capture in C# after it loads the html contents.
So is there a way I can more or less grab a screenshot using (or along with) HtmlAgilityPack so I can have a visual clue as to what happens every time I do page manipulations?
Here is my working code so far:
using HtmlAgilityPack;
using System;
namespace ConsoleApplication4
{
class Program
{
static void Main(string[] args)
{
string urlDemo = "https://htmlagilitypack.codeplex.com/";
HtmlWeb getHtmlWeb = new HtmlWeb();
var doc = getHtmlWeb.Load(urlDemo);
var sentence = doc.DocumentNode.SelectNodes("//p");
int counter = 1;
try
{
foreach (var p in sentence)
{
Console.WriteLine(counter + ". " + p.InnerText);
counter++;
}
}
catch (Exception e)
{
Console.WriteLine(e);
}
Console.ReadLine();
}
}
}
Currently, it scrapes and output all the p of the page in the console but at the same time I want to get a screen grab of the scraped contents but I don't know how and where to begin.
Any help is greatly appreciated. TIA

You can't do this with HTML Agility Pack. Use a different tool such as Selenium WebDriver. Here is how to do it: Take a screenshot with Selenium WebDriver

Could you use Selenium WebDriver instead?
You'll need to add the following NuGet packages to your project first:
Selenium.WebDriver
Selenium.Support
Loading a page and taking a screenshot is then as simple as...
using System;
using System.Drawing.Imaging;
using System.IO;
using OpenQA.Selenium;
using OpenQA.Selenium.Firefox;
using OpenQA.Selenium.Support.UI;
namespace SeleniumTest
{
class Program
{
static void Main(string[] args)
{
// Create a web driver that used Firefox
var driver = new FirefoxDriver(
new FirefoxBinary(), new FirefoxProfile(), TimeSpan.FromSeconds(120));
// Load your page
driver.Navigate().GoToUrl("http://google.com");
// Wait until the page has actually loaded
var wait = new WebDriverWait(driver, new TimeSpan(0, 0, 10));
wait.Until(d => d.Title.Contains("Google"));
// Take a screenshot, and saves it to a file (you must have full access rights to the save location).
var myDesktop = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
((ITakesScreenshot)driver).GetScreenshot().SaveAsFile(Path.Combine(myDesktop, "google-screenshot.png"), ImageFormat.Png);
driver.Close();
}
}
}

How do load FEEDS youtube apis v3 on windows store c#

to show a news feed, music, sports. thanks.
private void loadfeedYoutube()
{
string feedUrl="https://gdata.youtube.com/feeds/api/standardfeeds/most_popular";
var request=new
Feed<Video> videoFeed = request.Get<Video>(new Uri(feedUrl));
printVideoFeed(videoFeed);
static void printVideoFeed(Feed<Video> feed)
{
foreach (Video entry in feed.Entries)
{
printVideoEntry(entry);
}
}
}
I'm using:
using Google.Apis.Auth.OAuth2;
using Google.Apis.Services;
using Google.Apis.Upload;
using Google.Apis.Util.Store;
using Google.Apis.YouTube.v3;
using Google.Apis.YouTube.v3.Data;
Error: not finding Feed, request...

There is using myToolkit
private void GetYoutubeChannel(string feedXML)
{
try
{
SyndicationFeed feed = new SyndicationFeed();
feed.Load(feedXML);
List<YoutubeVideo> videosList = new List<YoutubeVideo>();
YoutubeVideo video;
foreach (SyndicationItem item in feed.Items)
{
video = new YoutubeVideo();
video.YoutubeLink = item.Links[0].Uri;
string a = video.YoutubeLink.ToString().Remove(0, 31);
video.Id = a.Substring(0, 11);
video.Title = item.Title.Text;
video.PubDate = item.PublishedDate.DateTime;
video.Thumbnail = YouTube.GetThumbnailUri(video.Id, YouTubeThumbnailSize.Large);
videosList.Add(video);
}
MainListBox.ItemsSource = videosList;
}
catch { }
}

You can try to use SyndicationFeed to help you,
check this example, which using Mytoolkit project to implement.
http://code.msdn.microsoft.com/windowsapps/Youtube-Sample-Get-Youtube-e9a3e0be
and you using feedUrl method is an old api which is v2 not v3.

#Lê Thiên Hoàng
using http://gdata.youtube.com/demo/index.html to generate you want to get.
if you want get music popular, then your RESTFul Api link is:
http://gdata.youtube.com/feeds/api/standardfeeds/most_viewed/-/{http://gdata.youtube.com/schemas/2007/categories.cat}Music?alt=rss
But I recommend if you can, using Youtube API Version3, is better and easier to get different category video.

How can I programmatically control Firefox, preferably with a C# application?

I'm looking to write a program that opens up an instance of Firefox, namely the default instance of Firefox that contains my various login information, and then simply switch through a few sites. I'm sort of able to do this, using the following code:
System.Diagnostics.Process.Start("firefox.exe", "thisIsMyURL");
However, as I'm sure you're mostly aware, this simply opens a new Firefox process with the given URL as a default site to open to. In order to do what I want, I'd essentially have to open a new Firefox process, do what I need to on the page, kill the process, and repeat this for each page I need. This is less than ideal. So, I'm hoping that someone will know of a way to programmatically control Firefox, through an API or library or something. I've searched on Google, and so far have only found outdated solutions that didn't really solve my problem in the first place.
As always, thanks for your help! Everything you can offer is appreciated.

You can use Selenium WebDriver for C #.
This is a cross-platform API that allows you to control various browsers using APIs for Java, C#, among others.

I was reading MSDN magazine a while back, and I saw an article about a project called "Watir" that piqued my interested, because I was doing a lot of automated testing at the time. I looked into it and found there is actually a project called WatiN which is .NET based. Check it out I think it is exactly what you're looking to do.

First start the process using :
Process.Start("firefox.exe", "www.example.com");
Then to kill it you need to do next:
Process[] processes = Process.GetProcessesByName("firefox.exe");
foreach (Process p in processes)
{
if (p.ProcessName.Equals("firefox.exe", StringComparison.OrdinalIgnoreCase))
{
p.Kill();
}
}
