I'm initializing my Chromium Browser like this:
CefSettings settings = new CefSettings();
settings.CommandLineArgsDisabled = false;
settings.CefCommandLineArgs.Clear();
settings.CefCommandLineArgs.Add("enable-3d-apis", "1");
settings.CefCommandLineArgs.Add("enable-webgl-draft-extensions", "1");
settings.CefCommandLineArgs.Add("enable-gpu", "1");
settings.CefCommandLineArgs.Add("enable-webgl", "1");
Cef.Initialize(settings);
var chromeBrowser = new ChromiumWebBrowser();
chromeBrowser.Address = "http://get.webgl.org/";
targetGrid.Children.Add(chromeBrowser);
So I try a lot of commands found here but to no avail. It does load the website and it says "my browser does support webgl but it isn't enabled." I should see a cube rotating by the way which I don't see. I looked for some SO threads regarding this, one of them complaining about the speed and I copied the initialization from there (only that command line args), still no luck. I also tried turning off the disabling commands before adding these like
settings.CefCommandLineArgs.Add("disable-webgl", "0");
without success. Could someone tell me how to initialize CefSharp 55's webgl properly?
The WPF one has many issues and I ended up using WinFormsHost to host the control in WPF. Only then I have full touch support and GPU acceleration.
Here is how I did it.
private CefSharp.WinForms.ChromiumWebBrowser wb_Main;
public MainWindow()
{
var cs = new CefSharp.CefSettings();
cs.UserAgent = "Mozilla/5.0 (Windows NT 10.0; WOW64; rv:51.0) Gecko/20100101 Firefox/51.0";
CefSharp.Cef.Initialize(cs);
InitializeComponent();
CefSharp.Cef.GetGlobalCookieManager().SetStoragePath(Directory.GetCurrentDirectory(), true);
wb_Main = new ChromiumWebBrowser("about:blank");
wfh_Main.Child = wb_Main; //WinformsHost control
}

I am attempting to load a chrome browser with selenium using my existing account and settings from my profile.
I can get this working using ChromeOptions to set the userdatadir and profile directory. This loads the browser with my profile like i want, but the browser then hangs for 60 seconds and times out without advancing through any more of the automation.
If I don't use the user data dir and profile settings, it works fine but doesn't use my profile.
The reading I've done points to not being able to have more than one browser open at a time with the same profile so I made sure nothing was open while I ran the program. It still hangs for 60 seconds even without another browser open.
m_Options = new ChromeOptions();
m_Options.AddArgument("--user-data-dir=C:/Users/Me/AppData/Local/Google/Chrome/User Data");
m_Options.AddArgument("--profile-directory=Default");
m_Options.AddArgument("--disable-extensions");
m_Driver = new ChromeDriver(#"pathtoexe", m_Options);
m_Driver.Navigate().GoToUrl("somesite");
It always hangs on the GoToUrl. I'm not sure what else to try.
As per your code trials you were trying to load the Default Chrome Profile which will be against all the best practices as the Default Chrome Profile may contain either of the following:
Extensions
Bookmarks
Browsing History
etc
So the Default Chrome Profile may not be in compliance with you Test Specification and may raise exception while loading. Hence you should always use a customized Chrome Profile as below.
To create and open a new Chrome Profile you need to follow the following steps :
Open Chrome browser, click on the Side Menu and click on Settings on which the url chrome://settings/ opens up.
In People section, click on Manage other people on which a popup comes up.
Click on ADD PERSON, provide the person name, select an icon, keep the item Create a desktop shortcut for this user checked and click on ADD button.
Your new profile gets created.
Snapshot of a new profile SeLeNiUm
Now a desktop icon will be created as SeLeNiUm - Chrome
From the properties of the desktop icon SeLeNiUm - Chrome get the name of the profile directory. e.g. --profile-directory="Profile 2"
Get the absolute path of the profile-directory in your system as follows :
C:\\Users\\Thranor\\AppData\\Local\\Google\\Chrome\\User Data\\Profile 2
Now pass the value of profile-directory through an instance of ChromeOptions with AddArgument method along with key user-data-dir as follows :
m_Options = new ChromeOptions();
m_Options.AddArgument("--user-data-dir=C:/Users/Me/AppData/Local/Google/Chrome/User Data/Profile 2");
m_Options.AddArgument("--disable-extensions");
m_Driver = new ChromeDriver(#"pathtoexe", m_Options);
m_Driver.Navigate().GoToUrl("somesite");
Execute your Test
Observe Chrome gets initialized with the Chrome Profile as SeLeNiUm
If you want to run Chrome using your default profile (cause you need a extension), you need to run your script using another browser, like Microsoft Edge or Microsoft IE and your code will lunch a Chrome instance.

i guys, in my enviroment with chrome 63 and selenum for control, i have find same problem (60 second on wait for open webpage).
To fix i have find a way by setting a default webpage in chrome ./[user-data-dir]/[Profile]/Preferences file, this is a json data need to insert in "Preferences" file for obtain result
...
"session":{
"restore_on_startup":4,
"startup_urls":[
"http://localhost/test1"
]
}
...
For set "Preferences" from selenium i have use this sample code
ChromeOptions chromeOptions = new ChromeOptions();
//set my user data dir
chromeOptions.addArguments("--user-data-dir=/usr/chromeDataDir/");
//start create data structure to for insert json in "Preferences" file
Map<String, Object> prefs = new HashMap<String, Object>();
prefs.put("session.restore_on_startup", 4);
List<String> urlList = new ArrayList<String>();
urlList.add("http://localhost/test1");
prefs.put("session.startup_urls", urlList);
//set in chromeOptions data structure
chromeOptions.setExperimentalOption("prefs", prefs);
//start chrome
ChromeDriver chromeDriver = new ChromeDriver(chromeOptions);
//this get command for open web page, response instant
chromeDriver.get("http://localhost/test2")

I'm using VS 2017 and coding in C#. I installed the 4 Vlc libraries to play videos in a Windows Form Application. I put a Vlc control in the form. And then, in the code, I wrote:
vlcControl1.SetMedia(curFolder + #"\media\1.mp4");
vlcControl1.Play();
When I run it, I get a "VlcLibDirectory not found". What I need to do? I see that I can set that directory through visual controls, in the VlcControl1 properties, but what is that folder?
I'm sorry this is late...
You got the first part, getting the packages in Visual Studio, now you need the libraries for it.
Download this: https://github.com/ZeBobo5/Vlc.DotNet/tree/master
Put the lib directory somewhere the application can find it, and set that VlcLibDirectory equal to a new DirectoryInfo(path to dir).
I did it like this:
var libDirectory = new DirectoryInfo(Path.Combine(".", "libvlc", IntPtr.Size == 4 ? "x86" : "x64"));
vlcControl1 = new Vlc.DotNet.Forms.VlcControl();
vlcControl1.VlcLibDirectory = libDirectory;
The library that it needs to be loaded is libvlc.dll that is found in the folder where is installed the VLC software.
I visited practically every Google result page for this, almost lost hope, but this worked for me in the end:
1) Created an object in my FormsApp file:
VlcControl vlcControl1 = new VlcControl();
2) Instantiated it in the constructor:
VlcControl vlcControl1 = new VlcControl();
3) In my FormsApp_Load() added the following lines:
vlcControl1.BeginInit();
vlcControl1.VlcLibDirectory = new DirectoryInfo(_exeFolder + #"\libvlc\win-x86"); //Make sure your dir is correct
vlcControl1.VlcMediaplayerOptions = new[] { "-vv"}; //not sure what this does
vlcControl1.EndInit();
YourControlContainer.Controls.Add(vlcControl1); //Add the control to your container
vlcControl1.Dock = DockStyle.Fill; //Optional
this.vlcControl1.Click += new EventHandler(vlcControl1_Click); //Optional - added a click event .Play()
Hope this helps someone.
I've also experienced this problem.
I just look into the properties of the VlcControl on the Form and change the VlcLibDirectory item under the Media Player category by browsing to the directory which the "libvlc.dll" located.
(in my application C:\Users\MCOT\source\repos\WindowsApp3\packages\VideoLAN.LibVLC.Windows.3.0.6\build\x86)
#Thanin's answer is what I needed, ... here is a code snippet to where the library should be installed.
//InitializeComponent();
using (RegistryKey rk = Registry.LocalMachine.OpenSubKey(
"SOFTWARE\\VideoLAN\\VLC",
RegistryKeyPermissionCheck.ReadSubTree,
RegistryRights.QueryValues))
{
_Vlc.SourceProvider.CreatePlayer(
new DirectoryInfo(rk.GetValue("InstallDir") as string),
new string[] { });
}
I have been trying to find this somewhere in the documentation, but can't seem to find anything relevant - could anybody share how to disable the logs created by a Selenium Grid node, in the file phantomjsdriver.log, (or if not, only write at a given level, e.g ERROR or WARN)?
I've come across an issue recently where WebDriver will run fine for a while using PhantomJS remotely via Selenium Grid, but after some time there seems to be a bug which causes a StackOverflowException to be thrown when trying to interact with driver instances - which I think I've tracked down to the size of the phantomjsdriver.log file where the Grid Node runs. This happens when the log file is around 600MB in size. Obviously this causes my nodes to become unusable after some time.
Right now, I am creating my PhantomJS remote WebDriver in the following way:
public static IWebDriver CreatePhantomGridDriver(string hubAddress)
{
if (hubAddress == null)
{
throw new ArgumentException(nameof(hubAddress));
}
PhantomJSOptions opts = new PhantomJSOptions();
opts.AddAdditionalCapability("phantomjs.page.settings.userAgent", "Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.65 Safari/537.36");
RemoteWebDriver driver = new RemoteWebDriver(new Uri(hubAddress), opts.ToCapabilities());
driver.Manage().Timeouts().SetPageLoadTimeout(new TimeSpan(0, 1, 0));
driver.Manage().Timeouts().ImplicitlyWait(new TimeSpan(0, 0, 1));
return driver;
}
I am using selenium-server-standalone-2.52.0 for my Grid, and it has 2 nodes registered, each exposing 8 PhantomJS drivers: java -jar selenium-server-standalone-2.52.0.jar -role node -hub http://MySeleniumGridHubServer:4444/grid/register -port 5556 -browser browserName=phantomjs,version=1.9.8.0,platform=ANY,maxInstances=8 -timeout 60 -maxSession 100
If there is some way that I can disable the phantomjsdriver.log file at the time that I start the node via command line, that would be ideal!
Additionally, there seem to be a number of features exposed by PhantomJSOptions and the PhantomJSDriverService classes, but they don't seem to be able to be used together to create a driver instance, and both expose a different set of properties!
Thanks
Could anyone tell me how to create a link from a LinkLabel in Visual Studio?
Say I'm trying to make the program pull up a browser window to www.google.com (in their default browser). How would I do that? I got the following from some example code I found:
HttpWebRequest head_request = (HttpWebRequest)WebRequest.Create("http://www.google.com");
head_request.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:6.0a2) Gecko/20110613 Firefox/6.0a2";
HttpWebResponse response = (HttpWebResponse)head_request.GetResponse();
But what I have doesn't do anything. If anything, it makes my browser go into a state of unresponsiveness.
I have
using System.Net;
using System.IO;
up top. Is that right? Thanks in advance!
What you can do like something below:
ProcessStartInfo sInfo = new ProcessStartInfo("http://mysite.com/");
Process.Start(sInfo);
An article about it: http://support.microsoft.com/kb/320478
Attach it to a link:
protected void hyperlink_Click(object sender, EventArgs e)
{
ProcessStartInfo sInfo = new ProcessStartInfo("http://mysite.com/");
Process.Start(sInfo);
}
Note: If you can't see it, then you should declare using System.Diagnostics; namespace.
The code below will open google.com in the default browser. You can call this code from anywhere. The click event of a button would be a good place to test it out!
Process.Start("http://google.com/");
