C# Selenium Webdriver

I started using selenium with CS and have one issue. When code is compiled, program cannot find webdriver path, because it's being moved into the .exe file. I fixed this problem, by copying driver into the bin folder, so program can access it again. However, I want it to be able to access that driver inside .exe file.
I was doing this in python using os path:
def resource_path(relative_path: str) -> str:
try:
base_path = sys._MEIPASS
except Exception:
base_path = os.path.dirname(__file__)
return os.path.join(base_path, relative_path)
If anyone knows how to do this in cs, please let me know.
Code that I'm using in c#:
var browser = new EdgeDriver();
browser.Navigate().GoToUrl(link);

webdrivermanager should be more helpful here. you can add its Nuget and use to manage drivers for browsers without requiring the driver exe files.

I use something like this and call this method everytime I need a browser.
public static InternetExplorerDriver InitBrowser(string browserName)
{
switch (browserName)
{
case "IE":
{
var IE_DRIVER_PATH = #"C:\PathTo\IEDriverServer";
InternetExplorerDriver driver = new InternetExplorerDriver(IE_DRIVER_PATH);
return driver;
}
}
return null;
}
This allows you to define the path from which to grab the driver, and so you wont have to depend on it being in your BIN folder. There are other solutions but this is what I have that works really well for me. You are set up to use this method for other browsers by adding more switch cases, and also from here you can easily add your browser options. You can call the method in your tests using:
InternetExplorerDriver driver = InitBrowser(IE);
Here it is simplified without the switch case:
var IE_DRIVER_PATH = #"C:\PathTo\IEDriverServer";
InternetExplorerDriver driver = new InternetExplorerDriver(IE_DRIVER_PATH);

Using IWebBrowserApp without admin rights possible?

I have a program that reads some data from a website, then clicks a link on that website and reads data again from the new site after navigation.
Everything works fine as long as the program is started with admin rights. The problem occurs when I start the program without admin rights. Here is some code:
void ReadHTML(string url)
{
try
{
InternetExplorer ie = new InternetExplorer();
IWebBrowserApp wb = (IWebBrowserApp)ie;
wb.Visible = false;
wb.Navigate(main.pathHcmOverview, null, null, null, null);
while (wb.Busy) ; // Here the program crashes already with exit code 0x800706ba
HTMLDocument doc = (HTMLDocument)wb.Document;
// Do something with the doc [I cut the code here as it is not relevant for the problem]
wb.Quit();
}
catch (Exception err)
{
}
}
The navigation command works, but the next command throws an error: "RPC Server not available - 0x800706ba".
Now my question: Can I use the code above only with admin rights? I did not find any information on that yet.
And if so, is there an alternative to accomplish my goal without admin rights?

I was able to resolve the problem by changing the following line
InternetExplorer ie = new InternetExplorer();
into
InternetExplorerMedium ie = new InternetExplorerMedium();
Tests worked fine after that. I will read into the documents now about the exact differences between those two.

how to get already opened IE browser handle in selenium?

I have one already opened IE browser , with some url.
After this, I Run below code which will open another IE browser. however it gives me only one window handle in below code.
Is it possible to get previously opened IE browser handle ?
IWebDriver IEdriver = new InternetExplorerDriver();
IReadOnlyCollection<String> browsers = IEdriver.WindowHandles;
foreach (String item in browsers)
{
IEdriver.SwitchTo().Window(item);
String url = IEdriver.Url;
}

I think this is what you're looking for:
String winHandleBefore = driver.getWindowHandle();
//Do whatever operations you have to do
for(String winHandle : IEdriver.getWindowHandles()){
IEdriver.switchTo().window(winHandle);
}

Be careful as what you are trying to do, is not robust solution to write tests cases. If one test case causes browser to crash you will be getting all the test cases failed.
Also I don't think it should be possible to get handles on previously opened window by default, because when you write code
IWebDriver IEdriver = new InternetExplorerDriver();
It calls for a constructor of InternetExplorerDriver class and opens new instance of Internet Explorer.

You can either go for close all browsers before starting your test case execution by killing the ie process from task manager.
foreach (Process process in Process.GetProcessesByName("iexplore"))
{
process.Kill();
}

Selenium IEDriver- Regarding PATH variable

I am working on creating a regression test suite using Selenium for IE Browser. I am using the IEDriver exe from Selenium website. As per instructions from Selenium,
"The Internet Explorer Driver Server
This is required if you want to make use of the latest and greatest features of the WebDriver InternetExplorerDriver. Please make sure that this is available on your $PATH (or %PATH% on Windows) in order for the IE Driver to work as expected."
Approach 1
I tried to setup PATH variable via batch file as follows
setlocal
set varC=%CD%\ChromeDriver
set varI=%CD%\IEDriver
set PATH=%PATH%;%varC%;%varI%
However i still face issues with IEDriver not working properly.
Approach 2
When i set PATH variable via "Advanced System Settings", everything seems to be working fine. Can someone confirm if this setting can't be done via batch file or if i am performing some wrong operation?
Here is how I am initializing driver
[OneTimeSetUp]
public void SetupTestFixture()
{
switch (ConfigPara.TestBrowser.ToLower())
{
case "ie":
Utility.KillProcess("iexplore");
DesiredCapabilities caps = DesiredCapabilities.InternetExplorer();
caps.SetCapability("ignoreZoomSetting", true);
caps.SetCapability("nativeEvents", false);
caps.SetCapability("allow-blocked-content", true);
caps.SetCapability("disable-popup-blocking", true);
caps.SetCapability("allowBlockedContent", true);
aOptIE = new OpenQA.Selenium.IE.InternetExplorerOptions();
aOptIE.InitialBrowserUrl = ConfigurationManager.AppSettings.Get("baseURL");
aOptIE.EnablePersistentHover = false;
aOptIE.RequireWindowFocus = true;
aOptIE.IntroduceInstabilityByIgnoringProtectedModeSettings = true;
System.Environment.SetEnvironmentVariable("webdriver.ie.driver", ConfigPara.IEDriverDirectory.FullName +"\\IEDriverServer.exe");
Utility.Instance.driver = new InternetExplorerDriver(ConfigPara.IEDriverDirectory.FullName, aOptIE);
break;
}
Utility.Instance.driver.Manage().Timeouts().ImplicitlyWait(TimeSpan.FromSeconds(7));
baseURL = ConfigPara.BaseURL;
Utility.Instance.wait = new OpenQA.Selenium.Support.UI.WebDriverWait(Utility.Instance.driver, TimeSpan.FromSeconds(30));
//utility = new Utility(driver);
}
[OneTimeTearDown]
public void SetupTestTeardown()
{
try
{
Utility.Instance.driver.Quit();
Utility.Instance.driver.Dispose();
}
catch (Exception)
{
// Ignore errors if unable to close the browser
}
Assert.AreEqual("", verificationErrors.ToString());
}

Hi actually you have to set the path of the IE driver that you downloaded form here http://docs.seleniumhq.org/download/
please do it like below
System.setProperty("webdriver.ie.driver","pathofIEdriver\\IEDriverServer.exe");
WebDriver driver = new InternetExplorerDriver();

User below code for C# webdriver:
System.Environment.SetEnvironmentVariable("webdriver.ie.driver", "Path\IEDriverServer.exe");

You can use webdriver manager class to handle it.
WebDriverManager.iedriver().setup();
Added in your maven pom file :
<dependency>
<groupId>io.github.bonigarcia</groupId>
<artifactId>webdrivermanager</artifactId>
<version>3.8.1</version>
</dependency>
You can also use Webdrivermanage dependency for Gradle. This will automatically maintain IE driver exe file.

How to launch a Google Chrome Tab with specific URL using C#

Is there a way I can launch a tab (not a new Window) in Google Chrome with a specific URL loaded into it from a custom app? My application is coded in C# (.NET 4 Full).
I'm performing some actions via SOAP from C# and once successfully completed, I want the user to be presented with the end results via the browser.
This whole setup is for our internal network and not for public consumption - hence, I can afford to target a specific browser only. I am targetting Chrome only, for various reasons.

As a simplification to chrfin's response, since Chrome should be on the run path if installed, you could just call:
Process.Start("chrome.exe", "http://www.YourUrl.com");
This seem to work as expected for me, opening a new tab if Chrome is already open.

// open in default browser
Process.Start("http://www.stackoverflow.net");
// open in Internet Explorer
Process.Start("iexplore", #"http://www.stackoverflow.net/");
// open in Firefox
Process.Start("firefox", #"http://www.stackoverflow.net/");
// open in Google Chrome
Process.Start("chrome", #"http://www.stackoverflow.net/");
For .Net core 3.0 I had to use
Process process = new Process();
process.StartInfo.UseShellExecute = true;
process.StartInfo.FileName = "chrome";
process.StartInfo.Arguments = #"http://www.stackoverflow.net/";
process.Start();

UPDATE: Please see Dylan's or d.c's anwer for a little easier (and more stable) solution, which does not rely on Chrome beeing installed in LocalAppData!
Even if I agree with Daniel Hilgarth to open a new tab in chrome you just need to execute chrome.exe with your URL as the argument:
Process.Start(#"%AppData%\..\Local\Google\Chrome\Application\chrome.exe",
"http:\\www.YourUrl.com");

If the user doesn't have Chrome, it will throw an exception like this:
//chrome.exe http://xxx.xxx.xxx --incognito
//chrome.exe http://xxx.xxx.xxx -incognito
//chrome.exe --incognito http://xxx.xxx.xxx
//chrome.exe -incognito http://xxx.xxx.xxx
private static void Chrome(string link)
{
string url = "";
if (!string.IsNullOrEmpty(link)) //if empty just run the browser
{
if (link.Contains('.')) //check if it's an url or a google search
{
url = link;
}
else
{
url = "https://www.google.com/search?q=" + link.Replace(" ", "+");
}
}
try
{
Process.Start("chrome.exe", url + " --incognito");
}
catch (System.ComponentModel.Win32Exception e)
{
MessageBox.Show("Unable to find Google Chrome...",
"chrome.exe not found!", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
