Using WebView2 browser when a user clicks a link that opens another program, this prompt shows up every time.
Is there a way to suppress this in WebView2?
You can use the NavigationStarting event to cancel navigations to URIs that start with the URI schemes you care about and then do whatever you like with that URI. For example, call ShellExecuteExW, or Windows.System.Launcher.LaunchUriAsync with the URI so that the OS opens the URI.
As Yu Zhou notes this is dangerous if its arbitrary websites opening arbitrary applications as in the case of a web browser. If you're going to skip this security prompt you should ensure that you own the web content or trust the web content in the WebView2 to not be malicious. If you are showing arbitrary URIs or user submitted web content you should not skip the prompt.
I can understand that you want to bypass the prompt, but it's by design and we can't change it. It is designed for security. This prompt is the only thing standing between every arbitrary site on the Internet (loaded inside your browser’s sandbox) and a full-trust application on your computer (running outside of the browser’s sandbox).
The only thing we can do to reduce the pain is to check the "Always allow..." checkbox, so that the prompt won't show at the next time.

I have an app that tests web page layouts in different browsers without requiring the user to download a new browser to their local. Every time when a user opens a new browser to test a page, I want this browser to open in a sandbox to limit the browser's actions in case of coming across any malware or dangerous sites.
How can I do that?
Note: The app is in C#.
You may also want to determine if this will be an acceptable workflow since each launched sandbox will only have the default browser by default. Additional browsers may have to be manually installed, even scripted, but will take time and slow down testing.
Configuring your sandbox:
You may be able to devise a workaround based on creating a .wsb file and populating it with a startup script. Your app can create this file programmatically with parameters and launch it.
https://www.windowscentral.com/how-configure-windows-sandbox-windows-10
Based on that you would probably have something like the following:
<Configuration>
<VGpu>Default</VGpu>
<Networking>Default</Networking>
<MappedFolders>
<MappedFolder>
<HostFolder>C:\FolderThatContainsBrowserInstaller\</HostFolder>
<ReadOnly>false</ReadOnly>
</MappedFolder>
</MappedFolders>
<LogonCommand>
<Command>Powershell.exe -ExecutionPolicy Unrestricted C:\users\WDAGUtilityAccount\Desktop\FolderThatContainsBrowserInstaller\ScriptThatInstallsBrowserAndLaunchesURL.ps1</Command>
</LogonCommand>
</Configuration>

You will have to decide what the ScriptThatInstallsBrowserAndLaunchesURL.ps1 actually does, but installing browser to test, then launching it with URL sounds like a fairly simple task.
I have a selenium automated task setup to login to a website to retrieve some information. It's very basic in the automation. Just logging in and clicking two links. I am running into an issue that is proving to be a problem.
The site in question uses the Authentication Required popup which is not a javascript popup but rather the regular windows auth popup. From what I have read this isn't handled out of the box with selenium.
I am using the "http://Username:Password#url.com" to get to the site but every now and then the site itself has issues on their end where it will prompt me again from username/password randomly. Sometimes I have to enter the username/password twice in a row when navigating there by hand.
Since my task just loops continuously for a few hours picking up the needed info I figured I would just use WebDriverWait to verify an element is present on the page. If the authentication popup appears, the element isn't present. No need to care about this run, so just start over.
The problem I am having is that when the Authentication popup is displayed and I hit my timeout limit I want to close the driver/browser window so that I can start the task over again. However, driver.Close() and driver.Quit() are not doing anything. The browser remains open and the unloaded page is still there with the login popup.
Is there anyway I can force close this? Switch focus to the browser window then force close?
The Alert Method, authenticateUsing() lets you skip the Http Basic Authentication box. The below code was tested on Google Chrome in java.
Alert alert = driver.switchTo().alert();
alert.authenticateUsing(new UserAndPassword(Username, Password));
In case it doesn't work and you might want to try this:

I am trying to automate testing for a site that uses an iFrame(?) sort of punch-out which links to another website's catalogue to make purchases. The process is the user will login and be able to select a set of catalogues to connect to. Upon clicking a catalogue set they will be prompted w/ this security dialog:
and once they click 'Show all content' they are prompted w/ this:
This will take them to the actual catalogue site where they can place orders. Is there any way to interact w/ these prompts?
Try AutoIT, It can click on the screen using windows ids

It'll create an exe and just call the exe whenever you like.
Selenium Webdriver is not able to interact with native browser popups. It does with JavaScript alerts and dialogs but that's not what you are trying to do.
The common solution to working with dialogs (file uploads, login dialogs) is to circumvent them by sending the file data or login info to the HTTP request.
See this question or this question for examples of these two scenarios. In your case you can't do that.
You could use another product (something other than Selenium) or change the IE configuration or the setup/environment of the tests so you are not prompted by these security alerts.
For example, for your first alert: "Only secure content is displayed", you can disable it by going in the IE options, security, Custom Level and then disabling Display non secure items.
I'm using WPF and C#.
I want to be able to launch a browser window, most likely IE, and provide known credentials so that the Windows-based application can handle the transition from itself to an outside browser without having the user enter his/her credentials again.
I do know how to launch the browser:
System.Diagnostics.Process.Start(url);
My main question is, how can I attach authentication to that? Perhaps by adding headers to it somehow?
Lastly, I don't really want to use the new WebBrowser control inside of WPF due to it's current problems with displaying with a transparent window.
1) You have to know how to "log in".
To do this login manually in the web application and trace the http traffic with http debugger like Fiddler. Pay attention what kind of http requests are sent, what names have the parameters, etc.
Once you know what sequence of http requests has to be send to log in you has to do this with the browser.
2) Implement log in automatically
2.1) If by any chance log in happens via http GET - just append the right query string to the url and start the browser. This could happen only if you control the web application and build in this mechanism, other wise log in is almost always implemented as POST with https.
2.2) If you have to do POST request you have several options:
2.2.1) You could provide local html document, that contains javascript and make ajax call to the login form from the javascript. To pass the parameters you could use get parameters.
2.2.2) If nothing else works you will have to use the browser via COM (WebBrowser control)
It's going to depend on how the web site handles user authentication. If you own the website, you can create a url that will log the user in with the information you provide.
Nick,
The authentication will be handled in different ways: -
Proxy Authentication is handled by Windows manually.
Forms Based authentication is handled by cookies, so the user needs to have the cookies present.
Windows NTML might be in the 'keychain' on the Operating system (Remember this password).
Cheers,
Phil.
I have a simple Tray icon program that opens a site using
System.Diagnostics.Process.Start("URL")
And it works fine independently, however when a service loads it, it gives a file not found exception when trying to open the URL, and after testing it can open normal extensions, e.g .txt (The service has desktop interaction enabled).
If you Process.Start a URL, it is loading a browser app, which isn't (for Vista/etc) going to display for a service (for the same reasons as your last question).
If you want the app to interact with the user/desktop, it shouldn't be a service - it should simply run when the user logs in. Note that any child-process that your service spawns will also be in the service's session.
If you just want to get data (through code) from the site, use WebClient etc.
