I create a Winform application, when i use webbrowser.
My problem, when i navigate to the site, the reCAPTCHA doesn't show. I got an error message my webbrowser doesn't support, i should update.
If i know right, the winform webbrowser work from IE what we have got in our computer.
My computer has got IE 11. I tried check this website with my IE, and ther the reCAPTCHA working perfectly.
How can i solved this problem? I want show the reCAPTCHA in my build in webbrowser in my winform.
The version of the WebBrowser is the problem:
The only thing that you need to do is to set the version of the browser in the key registry:
Something like this will do the job:
var appName = System.IO.Path.GetFileName(System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName);
Microsoft.Win32.Registry.SetValue(#"HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION",
appName, 11000, Microsoft.Win32.RegistryValueKind.DWord);
//where: 11000 is currently the last version of iExplorer
Please note that 11000 is the value that worked(for me). If you use 10000 or lower it is not going to work.

I run multiple (2) IE web-drivers together.(for user side and admin side tests)
When the InternetExplorer WebDriver click on link/button that opens an modal popup, login page are opened on new window (abnormal).
When the ie webdriver popup the window , I can see for a fraction of a second the correct address the browser should load (in URL line) , but immediatly it changed to the login url, and required enter username and password.
I found the same problem in this link,
I made the solution there, but I still have not solved the problem, and I get an entry window instead of the expected window.
see this screenshot
My IE version is 11.
My Selenium.WebDriver is 3.141.0.0
My ie webdriver is IEDriverServer_x64_3.141.5
My InternetExplorerOptions:
private static InternetExplorerOptions ieOptions = new InternetExplorerOptions
{
EnsureCleanSession = true ,
EnableNativeEvents = true ,
RequireWindowFocus = true ,
EnablePersistentHover = true ,
ForceCreateProcessApi = true ,
BrowserCommandLineArguments = "-framemerging -private"
};
I added the registry keys:
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Internet Explorer\Main\FrameMerging\(DWORD)00000000
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Internet Explorer\Main\TabProcGrowth\(DWORD)00000000
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BFCACHE\iexplorer.exe\(DWORD)00000000
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BFCACHE\iexplorer.exe\(DWORD)00000000
Edited:
By the Deepak-MSFT references, I understand that the issue caused by more than one IE web-driver instances.
I tried to kill the IE driver also by adding the ConfirmCleanSession = trueoption to the code, and also manually by running of the following statements from the command line (before running the test);
taskkill / F / IM iexplore.exe / T
taskkill / F / IM IEDriverServer.exe / T
But it did not help once I set 2 IE web-drivers to work together.
(When I tried to run the test only on one driver - it worked great!)
I would appreciate help in solving the problem!
This issue is due to a quirk of IE itself and how the driver creates the popup window for the browser.
The workaround is to ensure there are no iexplore.exe processes running when you start the session with the driver.

My Solution:
Split the test case into two tests:
First Test -
Use the IE web-driver for the first site (in my case - the admin side), and parallel use another web-driver (which does not cause problems like Chrome web-driver) for the second site (in my case - the admin side)
And a second test-
Use the other web-driver above for the first site, and parallel use the IE web-driver for the second site.
So I covered the tests in IE for the two sites.
I am trying to access a webpage (that is not under my control) namely allscripts sandbox via a WebBrowser control. My computer's internet explorer is correctly set up for said webpage (Added in Trusted Sites, Allowed and installed all active-x addons, running in compatibility mode, etc).
The webbrowser control displays the following error:
This webpage wants to run 'Some ActiveX control' which isn't compatible with Internet Explorer's enhanced security features. If you trust this site you can disable Enchanced Protected Mode for this site and allow the control to run.
I have not enabled (to the best of my knowledge) the enhanced protected mode.
Also trying to ignore the errors and continue with log-in displays a Message
The Centricity's container for .NET-based pages failed to initialize. Make sure your .NET environment is configured to grant Full Trust to this Website.
The above was also an error on the default IE until i run the command %WINDIR%\Microsoft.NET\Framework\v2.0.50727\caspol -q -m -cg Trusted_Zone FullTrust.
I have tried various registry keys but none seemed to work.
I have also tried implementing a custom IInternetSecurityManager that Maps all urls to zone Trusted and returns URLPOLICY_ALLOW on all ProcessUrlAction calls.
Any suggestion would be appreciated.
The problem could be that webbrowser uses by default an old version of the IE. Take a look at Use latest version of Internet Explorer in the webbrowser control
The webbrowser control is ie11 wrapped with a com wrapper that throttles back ie11 to ie7 mode. There's not a lot else going on there that I can imagine would cause your issue.
Since this page works for you when you run ie11 externally then the most likely explanation seems to be your attempt to force the control into ie11 mode is the problem.
I suggest you try Mentor's code here:
Set WPF webbrowser control to use IE10 mode
Which will automate adding the name of the running program to the registry.
var pricipal = new System.Security.Principal.WindowsPrincipal(
System.Security.Principal.WindowsIdentity.GetCurrent());
if(pricipal.IsInRole(System.Security.Principal.WindowsBuiltInRole.Administrator)) {
RegistryKey registrybrowser = Registry.LocalMachine.OpenSubKey
(#"Software\\Microsoft\\Internet Explorer\\Main\\FeatureControl\\FEATURE_BROWSER_EMULATION", true);
string myProgramName = Path.GetFileName(System.Reflection.Assembly.GetExecutingAssembly().Location);
var currentValue = registrybrowser.GetValue(myProgramName);
if (currentValue == null || (int)currentValue != 0x00002af9)
registrybrowser.SetValue(myProgramName, 0x00002af9, RegistryValueKind.DWord);
}
else
this.Title += " ( Первый раз запускать с правами админа )";
The WebBrowser control shipped with .NET 4.7 is throwing lots of JavaScript errors. For example, we tried with www.yahoo.com and we get multiple JavaScript errors. One such example is shown below:
If we browse the same link in internet explorer 11, we are not getting any error and browsing session goes smooth. Note that we already set Browser Emulation registry setting for IE 11. Used the Link to Set IE 11 Emulation. The Registry Key for the Emulation is:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION
(For 64 bit machine)
Re-production steps
Create a Visual C# Windows Forms Application
Place Web-Browser Control and a Command Button in the Form
Add the Following code in the command button Handler:
private void button1_Click(object sender, EventArgs e)
{
webBrowser1.Navigate("http://www.yahoo.com");
}
That is all. Once we click the command button, we have to respond to multiple JavaScript errors. How do we resolve this issue?
Note that we already have Browser Emulation for IE is set to 11 (in Registry). We do not want to suppress the Error, as we lose the service provided by the JavaScript. For example, click the “Cricket” button in the very top of the Yahoo page:
I am using Selenium in C# on Windows 10. The site under test should challenge with a Windows Security login box in IE, which it does. But the login box appears to block the call.
var home = "https://site.under.test.com/";
driver = new InternetExplorerDriver(AppDomain.CurrentDomain.BaseDirectory);
driver.Url = home;
driver.Manage().Window.Maximize();
driver.Navigate().GoToUrl(home + "secure/");
//code to handle login box goes here, never gets executed unless the dialog box
//is manually addressed or something times out in GoToURL(),
//and then the dialog box doesn't work.
The login box appears:
Click here for screenie of the login box
But the execution is stalled on the GoToUrl() call:
Click here for screenie of execution
Doesn't matter what code I place after this to handle the popup, execution is blocked until something times out inside GoToUrl().
Is this expected behavior? How does one get around it?
Clarification: The problem is not how to enter data into the popup. It is about the code execution not advancing to the point where I can enter data into the popup without intervention or timeout.
This works on Win8.1, but not on Win10
The Webdriver no longer officially supports Basic Authentication. It has been removed from the Java code and the .Net version works accidentally. From my experience you can expect it to work (for now) on Win7-8.1, but not on Win10
This from Selenium support:
The support of authentication dialogs was removed from the java bindings with this commit.
I am surprised, they are still present in the c# binding, because there is no support for basic authentication in the webdriver specification.
Not sure if you found the answer yet but here is what I found so far.
.GoToUrl waits for the page to load and since the page has not loaded yet, it waits and waits and throws exception.
You can enter the url usign Javascript. Below for is .Net code for it
string script = "window.location = \'" + url + "\'";
((IJavaScriptExecutor)driver).ExecuteScript(script);
You have to manage your own wait after using the above code.
And Selenium still doesnt work with the Windows Security dialog that you see after this (Or, I havent found any info anywhere that shows how to make Selenium work with this dialog)
The best solution I have found so far is to use AutoIT, and use TAB commands within AutoIT to enter username, move to password adn enter password and then do tab tab until you get to submit button and then click on this location. Please comment here if you have found any better solution than this until now
When I access the page with the browser (ie9), the browser is rendering ok.
When I use the WebBrowser control I have JavaScript errors.
I know I can suppress the scripts errors, but I want them to run correctly, because they affect the rendering and the functionality of the page.
How can I solve this problem ? Can I integrate IE9 directly in the Windows Form and use similar methods like with the WebBrowser control (navigate,get id, invoke click) ?
Thanks.
What I would do is assign an object to webbrowser.ObjectForScripting and then inject a javascript function that assigns windown.onerror to a wrapper that calls the external script in the host app. Like:
window.onerror = function(message, url, lineNumber)
{
window.external.errorHandler(message, url, lineNumber);
}
Refere to:

If you have IE9 installed, the WebBrowser will still use IE7 mode unless you override this behaviour with a registry setting - as described in this StackOverflow answer. This is the most likely cause of the JavaScript errors you're getting in the WebBrowser (because you're not seeing the same errors in IE9).
You can make the registry setting using the following c# code (which sets IE10 mode if Windows 8 is detected) and changing app-name.exe to match your own application. You should add an error handler for the case where there are insufficient privileges (admin privileges are required to write to this registry key).
string installkey = #"SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION";
string entryLabel = "app-name.exe";
System.OperatingSystem osInfo = System.Environment.OSVersion;
string version = osInfo.Version.Major.ToString() + '.' + osInfo.Version.Minor.ToString();
uint editFlag = (uint)((version == "6.2") ? 0x2710 : 0x2328); // 6.2 = Windows 8 and therefore IE10
RegistryKey existingSubKey = Registry.LocalMachine.OpenSubKey(installkey, false); // readonly key
if (existingSubKey.GetValue(entryLabel) == null)
{
existingSubKey = Registry.LocalMachine.OpenSubKey(installkey, true); // writable key
existingSubKey.SetValue(entryLabel, unchecked((int)editFlag), RegistryValueKind.DWord);
}
You can use the following code line to get rid of those types of errors:
webBrowser1.ScriptErrorsSuppressed = true;
It will prevent getting JavaScript errors.
So i know the post is old, but it was a recent problem for me and i had to do some serious digging and thinking outside the box.
basically like most replies here - you cannot alter the webbrowser control to use the most recent IE engine. mine uses IE7 by default, i have seen some replies that basically changes/ adds stuff to registry, am always not comfy when it comes to the registry, a cleaner way to address this issue would be to append code on your website that forces it to use the most current IE engine on any pc and works like a charm.
if you have access to the web.config file of the page you intend to browse, simple append:
<system.webServer>
<httpProtocol>
<customHeaders>
<clear />
<add name="X-UA-Compatible" value="IE=edge" />
</customHeaders>
</httpProtocol>
</system.webServer>
and your site would force webbrowser control to run the most current IE engine on your computer. Other options are found here:
https://www.leapinggorilla.com/Blog/Read/1016/ie-ate-my-css---disabling-compatability-mode
I should state that this would only work if you have access to the page / web.config of the website/ application you are trying to access- which was my case.
THe WebBrowser control uses IE7. So if there is a problem then your script does not work for IE7 and you will have to fix that.
You cannot integrate IE9 as it depends on it being installed on the computer and not everyone has IE9 installed.
As a help to whoever else may have this problem, I tried all these things and nothing worked for me. Here's what does work. I am not sure exactly what causes this error, but apparently when you just press "F5" in VS to debug your app, it runs YourProject.vshost.exe as the process name. If you run the same app from the command line, it will show up as YourProject.exe, and the javascript errors vanish. I think IE sees the app running visa via VSHOST and decides this is fishy and disables javascript from loading correctly.
So... go into your project setting for your executable.
Select "Debug" options.
Select "Start External Program".
Browse to and select Debug\YourProgram.exe (NOT YourProgram.vshost.exe).
Save, recompile, and hit F5.
Everything should work as per usual now, and Visual Studio even attaches to the process for you automatically.
Enjoy!
