LSP hover text markdown links from C# not working

I'm working on a VSCode extension with an LSP (implemented in C#/Omnisharp). I've implemented my language hover provider in the LSP and it's working fine. However, I want to add a clickable [vscode] command link to the hover. I've done this before using markdown in extension Typescript code like [Label](command:some-command), but it's not working from the LSP C# code. From there it just displays flat text as Label, but not as a clickable URI link. If the Uri is a regular https link it works, but not if it's a vscode Uri. Anyone know the magic to enable vscode command links in markdown from LSP C# code?

You need to set the markdown content isTrusted flag to get links to work. For a language extension server you need edit the LanguageClientOptions in the client's typescript file.
let clientOptions: LanguageClientOptions = {
markdown: {
isTrusted: true,
},
}
let client = new LanguageClient('myClient', 'My Client', serverOptions, clientOptions);

How to get Selenium to operate two browser windows using only one driver selenium (using c# and chromedriver)?

I am attempting to control two browser windows via selenium using c# and a single chromedriver. The reason being that I need to share session details accross browser windows.
The code that I have tried and failed with is below;
var options = new ChromeOptions();
options.AddArguments("chrome.switches", "--disable-extensions --disable-extensions-file-access-check --disable-extensions-http-throttling --disable-infobars --enable-automation ");
options.AddUserProfilePreference("credentials_enable_service", false);
options.AddUserProfilePreference("profile.password_manager_enabled", false);
options.PageLoadStrategy = PageLoadStrategy.Default;
ChromeDriverService service = ChromeDriverService.CreateDefaultService();
service.HideCommandPromptWindow = true;
var Driver = new ChromeDriver(service, options);
//THIS WILL OPEN A NEW WINDOW. BUT BECAUSE IT IS A NEW DRIVER DOES NOT WORK FOR SHARING SESSION DETAILS.
//var TestDriver = new ChromeDriver(service, options);
//TestDriver.Manage().Window.Maximize();
//THIS JUST OPENS UP A NEW TAB. NOT A NEW WINDOW (IT WOULD SEEM MOST DOCUMENTATION SUGGESTS THAT IT SHOULD)
IJavaScriptExecutor jscript = Driver as IJavaScriptExecutor;
jscript.ExecuteScript("window.open();", "google.com.au");
//TRY USING THE SEND KEYS TECHNIQUE. NOTHING HAPPENS
var test = Driver.FindElement(By.TagName("html"));
test.SendKeys(Keys.Control + "n");
test.SendKeys(Keys.Control + "t");
//TRY AGAIN USING THE SEND KEYS TECHNIQUE USING A DIFFERENT TAG. NOTHING HAPPENS
var blah = Driver.FindElements(By.TagName("body"));
blah[0].SendKeys(Keys.Control + "t");
//TRY USING ACTIONS. NOTHING HAPPENS
Actions action = new Actions(Driver);
action.SendKeys(OpenQA.Selenium.Keys.Control + "n");
action.Build().Perform();
I may resort to AutoIt to open a browser if I have to, but one more dependency is not what I need. Documentation everywhere around the web seems to suggest than all the options I tried above should work...I suspect it may be a chromedriver issue of some kind.
Any ideas on how to achieve my goal would be greatly appreciated
UPDATE.
Arnons answer below lead me to the solution. If you are in a similar situation the best thing to do is just open up the browser console (from developers tools) and experiment with javascript until you get what you want. Then just execute that. In the end executing the following code has worked for me.
IJavaScriptExecutor jscript = Driver as IJavaScriptExecutor;
jscript.ExecuteScript("window.open('https://www.bing.com.au','_blank','toolbar = 0, location = 0, menubar = 0')");
The other alternative was to use Autoit, which I also got working, much easier than I did figuring out the javascript. But one less dependency is best :)
UPDATE2.
Further complications arise with trying to control the window as an independent browser window. I believe any new window created from a parent window, has the same process id (at least my testing has indicated so), and for all intense and purpose is treated as a tab in the selinium driver. I therefore conclude that certain things are just not possible (for example relocating the child browser window on the screen).

Your first attempt using ExecuteJavaScript was very close, but In order for it to open a new window instead of new tab, you should add the following arguments: `"_blank", "toolbar=0,location=0,menubar=0" to it.
See this question for more details.

I should have read the question better, here is my solution. Ended up using this for selecting windows that popped up after clicking a button but should work with swapping between windows.
//---- Setup Handles ----
//Create a Handle to come back to window 1
string currentHandle = driver.CurrentWindowHandle;
//Creates a target handle for window 2
string popupWindowHandle = wait.Until<string>((d) =>
{
string foundHandle = null;
// Subtract out the list of known handles. In the case of a single
// popup, the newHandles list will only have one value.
List<string> newHandles = driver.WindowHandles.Except(originalHandles).ToList();
if (newHandles.Count > 0)
{
foundHandle = newHandles[0];
}
return foundHandle;
});
//Now you can use these next 2 lines to continuously swap
//Swaps to window 2
driver.SwitchTo().Window(popupWindowHandle);
// Do stuff here in second window
//Swap back to window 1
driver.SwitchTo().Window(currentHandle);
// Do stuff here in first window

You need to explicitly tell Selenium which tab you wish to interact with, which in this case would be;
driver.SwitchTo().Window(driver.WindowHandles.Last());

TestStack/White API

I'm trying to automate an application using TestStack/White API (Which is based on Microsoft's UI Automation library).
The problem is the following:
At a certain point of automation, I have to deal with an "Dialog" window, which looks to be a separate process, if i look at "Windows Task Manager". But no matter how i try to access the "Dialog Window" (Class, ID, Text, ControlType, etc.) I'm not able to access it.
You can find the UISpy image and code below...
Using UISpy - Dialog Information
using (var DISCLAIMER_App = Application.Attach(#"PathToExecutable"))
using (var DISCLAIMER_Window = DISCLAIMER_App.GetWindow(SearchCriteria.ByClassName("#32770"), InitializeOption.NoCache))
{
var IAccept_button = DISCLAIMER_Window.Get<Button>(SearchCriteria.ByText("I accept"));
IAccept_button.Click();
}
# I've tried also Application.Launch, Application.AttachOrLaunch.
# I also looked to be sure that the Dialog window is a separated process and doesn't belong to any parent window.
Any suggestions?

Found the Solution, had to use "ProcessStartInfo()" and pass the return data to "Application.AttachOrLaunch()":
var psi = new ProcessStartInfo(#"PathToExecutable");
using (var DISCLAIMER_App = Application.AttachOrLaunch(psi))

Cannot add icon in shell extension with C#

I've found a very nice tutorial and i am trying to understand something that is not in this tutorial (because the tut itself works fine)
http://www.codeproject.com/Articles/9163/File-Rating-a-practical-example-of-shell-extension
When you look at applications like WinRar, TortoiseSVN, Antivirus-apps and many more, there is an icon next to the Shell Extension Item.
I would like to know how this is done. (Programmatically with C#)
Adding a separator works, adding a submenu works and click+action also works, but i'm struggling with the icon. This cannot be so hard. Can somebody help me?
And please don't say that Microsoft doesn't longer support this in .NET 4.0, because it is not guaranteed and therefore they don't supply samplecode. If all those other apps can do it, then it is possible.
Please supply me some sample code, some tutorials or maybe even a working piece of code.

Please have a look at the following article, it uses .NET 4.0 it to create Windows Shell Extensions using the SharpShell nuget package.
NET Shell Extensions - Shell Context Menus
Using this library, you can set the image directly while creating the contextmenustrip as shown below
protected override ContextMenuStrip CreateMenu()
{
// Create the menu strip.
var menu = new ContextMenuStrip();
// Create a 'count lines' item.
var itemCountLines = new ToolStripMenuItem
{
Text = "Count Lines...",
Image = Properties.Resources.CountLines
};
// When we click, we'll count the lines.
itemCountLines.Click += (sender, args) => CountLines();
// Add the item to the context menu.
menu.Items.Add(itemCountLines);
// Return the menu.
return menu;
}

You only have to add to the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Classes*\shellex\ContextMenuHandlers
and here is the code:
string TimeStamp = DateTime.Now.ToString("dd-MM-yyyy");
string key = "HKEY_LOCAL_MACHINE\\SOFTWARE\\Classes\\*\\shellex\\ContextMenuHandlers\\Winrar";
string valueName = "MyWinrar";
Microsoft.Win32.Registry.SetValue(key, valueName, HERE WHAT YOU WANT TO START, Microsoft.Win32.RegistryValueKind.String);
i hope it works for you!

All the apps you listed use COM and unmanaged code to create overlay icon handlers. There is even a special project TortoiseOverlays that provides a common library for drawing icons for TortoiceCSV, TortoiseSVN and TortoiseGIT. You can take a look at it's source code to find out how it is done. If you want to draw similar icons, you should probably just reuse it.
Using .Net for this type of extensions is not recommended, because when multiple extensions, built against different .Net versions would attempt to load in explorer process, they will crash the explorer.

C# - What is the Select Source dialog as it applies to the GetDevice method?

I am trying to use a method that is described like this:
public Device GetDevice(string productName)
The productName is the name of the device as it appears in the Select Source dialog.
What is the Select Source dialog that's being referred to?

As this link mentions (look for the "Showing the “Select Source” dialog" heading), this is a dialog that allows users to select an ISIS device. It's part of the DotImage framework, called with ShowSelectSource and is used like this:
IsisDevice dev = null;
if (this.acquisition.ShowSelectSource(this)) dev = this.acquisition.Devices.Default;
I would guess that this works similarly to a FolderBrowserDialog. The user selects the device of his choosing and you can then use his selection to retrieve the Device itself with GetDevice.

I had to use Google to find out which library you are using.
Anyway: open the atalasoft documentation, once there, click search, and search for 'select AND source AND dialog'. Click the secondd hit '2: Getting Started with DotTwain' and read 'Showing the "Select Source" dialog'
