Selenium - How to hide command prompt window

I am trying to hide command prompt window when starting selenium chrome, but I can't figure it out.
Here is my code:
var driverService = ChromeDriverService.CreateDefaultService();
driverService.HideCommandPromptWindow = true;
var chromeOptions = new ChromeOptions();
chromeOptions.AddArguments("--headless");
var browser = new ChromeDriver(driverService, chromeOptions);
But it crash on: System.InvalidOperationException: 'session not created: This version of ChromeDriver only supports Chrome version 85
I tried to manually add path to driver but It crash's also.
Different code I used
var driverService = ChromeDriverService.CreateDefaultService();
driverService.HideCommandPromptWindow = true;
var chromeOptions = new ChromeOptions();
chromeOptions.AddArguments("--headless");
chromeOptions.BinaryLocation = "C:\\Users\\TriX\\Downloads\\chromedriver_win32";
var browser = new ChromeDriver(driverService, chromeOptions)
Now it crash on: OpenQA.Selenium.WebDriverException: 'unknown error: Failed to create Chrome process.'
Thanks for help I am completely lost :(
I tried different codes as shown, but without success.

Thanks to #r000bin i managed to resolve the problem. I also find out that I installed outdated version of ChromeDriver. So, I downloaded the correct one and it started to work.
I had old ChromeDrive nuget version
Downloaded the new one and uninstalled old one
Started to work :)

Enable Firefox Popup Blocking using C# and Selenium

I'm using the Selenium 3.14 Webdriver to test a site with Firefox. (I test other browsers also - but this problem is with Firefox).
For some tests I want to enable popup blocking. My Firefox instantiation is:
driver = new FirefoxDriver(geckodriverDirectory);
driver.Manage().Timeouts().PageLoad = TimeSpan.FromMinutes(1.0d);
I tried adding an option, as follows:
var options = new FirefoxOptions();
options.SetPreference("disable-popup-blocking", false);
driver = new FirefoxDriver(driverDir, options);
driver.Manage().Timeouts().PageLoad = TimeSpan.FromMinutes(1.0d);
But that failed to enable popup blocking. Any ideas for setting the correct Firefox option?

I finally solved this by setting the following preference instead of the preference shown above:
options.SetPreference("dom.disable_open_during_load", true);
The true value seems counter intuitive - because the impact is to have popup blocking enabled - but it works.
It would be great if Firefox would publish a list of preferences that their webdriver recognizes.

ChromeDriver v90 does not give correct URL when connecting to remote-debugging port through the ChromeDriverService

We use ChromeDriver in C# to connect to existing instances of Chrome that have the remote debugging port 9222 set. Here is how we connect:
var svc = ChromeDriverService.CreateDefaultService(path);
ChromeOptions options = new ChromeOptions();
options.DebuggerAddress = "127.0.0.1:9222";
var driver = new ChromeDriver(svc, options);
var url = driver.Url;
The problem is that the value of driver.Url is not what it used to be when using ChromeDriver version 88.
At that point and all earlier versions, driver.Url was the value of the URL for the current active tab in Chrome. So if Chrome had five tabs open and tab 4 is active, the Url was that of tab 4. And that made sense.
Once we upgraded to version 90 that is no longer the case. It appears that the value of Url is... well it's not clear. Sometimes the last active tab, sometimes some other tab, sometimes the first. I do not see a pattern.
Is this an error in ChromeDriver? In the past, whatever was the active tab was the one that driver.Url yielded. Now it's indeterminate which wreaks havoc with our code.
Update: If I have two tabs open, then the driver.Url and driver.Title are for the tab that was just prior active. So always the other tab. With 3 tabs it may be the 2nd to the last active tab. This feels like a off-by-one error within an internal array of tabs.

I had the same problem. I solved it using the method suggested here
ChromeDriverService driverService =
ChromeDriverService.CreateDefaultService();
var options = new ChromeOptions();
options.DebuggerAddress = "127.0.0.1:9222";
var driver = new ChromeDriver(driverService, options);
driver.SwitchTo().Window(driver.WindowHandles[0]); // Switch to the recently opened tab
MessageBox.Show("driver.Url: " + driver.Url);

C# selenium chromedriver click on Allow store files on this device

Hi.
How can I click on 'Allow' button? I really can't find any solution in the internet. I don't want to use c++ hooks or simulate mouse clicks by coordinates. Is there any good way to allow this notification?
new ChromeOptions.AddUserProfilePreference("profile.default_content_setting_values.automatic_downloads", 2);
doesn't help

Found two solutions:
1) Thanks for #Floren 's answer: C# selenium chromedriver click on Allow store files on this device
There is an argument for Chromium --unlimited-storage
Chromium source code reference:
// Overrides per-origin quota settings to unlimited storage for any
// apps/origins. This should be used only for testing purpose.
const char kUnlimitedStorage[] = "unlimited-storage";
# Prevent the infobar that shows up when requesting filesystem quota.
'--unlimited-storage',
C# usage:
var chromeOptions = new ChromeOptions();
chromeOptions.AddArgument("--unlimited-storage");
var driver = new ChromeDriver(chromeOptions);
2) #Simon Mourier's answer C# selenium chromedriver click on Allow store files on this device
Click on Allow button using .NET UIAutomation
var andCondition = new AndCondition(new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Button), new PropertyCondition(AutomationElement.NameProperty, "Allow"));
AutomationElement chromeWindow = AutomationElement.FromHandle(_windowPointer); // IntPtr type
var buttonsFound = chromeWindow.FindAll(TreeScope.Descendants, andCondition);
if (buttonsFound.Count > 0)
{
var button = buttonsFound[0];
var clickPattern = button.GetCurrentPattern(InvokePattern.Pattern) as InvokePattern;
clickPattern.Invoke();
}

You can't, this is an OS level dialogue, not something inside the DOM.
The way to get around it is by using desired capabilities to configure chrome to not show this dialogue.
I'm going to suggest
ChromeOptions options = new ChromeOptions();
options.AddUserProfilePreference("download.prompt_for_download", 0);
options.AddUserProfilePreference("settings.labs.advanced_filesystem", 1);
Other potential commands to add the options if AddUserProfilePreference doesn't work would be:
AddLocalStatePreference
AddAdditionalChromeOption
AddAdditionalCapability
For more details about desired capabilities and chrome have a look at:
The ChromeOptions documentation
This list of command line switches, or the command line switched defined directly in code.
The preferences defined directly in code
The ChromeOptions class in the Selenium codebase

var chromeOptions = new ChromeOptions();
var downloadDirectory = #"C:\Users\";
chromeOptions.AddUserProfilePreference("download.default_directory", downloadDirectory);
chromeOptions.AddUserProfilePreference("download.prompt_for_download", false);
chromeOptions.AddUserProfilePreference("disable-popup-blocking", "true");
chromeOptions.AddUserProfilePreference("profile.default_content_setting_values.automatic_downloads", 1);
IWebDriver _driver = new ChromeDriver(chromeOptions);
Can you try with this one ?

is it possible to interact or avoid ChromeDriver (Webdriver) save password alert?

is it possible to interact with save password alert in ChromeDriver? or just to configure chromedriver such that it doesn't appear.
I have tried following things however it's not working.
ChromeOptions Options = new ChromeOptions();
Options.AddArgument("--enable-save-password-bubble=true");
IWebDriver.driver.SwitchTo().Alert().Accept();

The --enable-save-password-bubble=true is deprecated from what I've seen. I've done a lot of searching on this recently and this is the fix that worked for me. Note that false should not be surrounded by quotes.
var options = new ChromeOptions();
options.AddUserProfilePreference("credentials_enable_service", false);
options.AddUserProfilePreference("profile.password_manager_enabled", false);
