Installation

dotnet package add Unfucked.Windows

using Unfucked;
using Unfucked.Windows;

Usage

Arguments

• Command line argument marshalling with correct escaping and quoting
  • String to array

    IEnumerable<string> argv = WindowsProcesses.CommandLineToEnumerable("arg1 arg2");
    

  • Array to string (in the Unfucked library, Unfucked.Windows is not required)

    string args = Process.CommandLineToString(["arg1", "'argument' \"2\""]);
    

• Get command line for processes not started by the current process, includes program filename
  • One big string

    string commandLine = process.CommandLine;
    // "C:\path\to\myprogram.exe --arg1 --arg2"
    

  • Split into tokens

    IEnumerable<string> commandLine = process.CommandLineSplit;
    // ["C:\path\to\myprogram.exe", "--arg1", "--arg2"]
    

Console

• Detach a console application from its console window if you want to prevent it from receiving Ctrl+C, because it's a child process of your console application, you're handling that signal in your parent process using Console.CancelKeyPress, and you don't want the console sidestepping your parent and killing your child.

  using Process child = Process.Start("child.exe", "args")!;
  child.DetachFromConsole();
  

Internationalization

• Get locale of the operating system, rather than the user

  CultureInfo machineCulture = Cultures.CurrentMachineCulture;
  

Processes

• Easier to get program's basename without memory leaks

  string? basename = SystemWindow.ForegroundWindow.ProcessExecutableBasename;
  

• Get parent process of a process

  using Process? parent = Process.GetCurrentProcess().Parent;
  parent = Process.GetParentProcess(childPid);
  

• Get descendant processes recursively of a process

  IEnumerable<Process> decendants = Process.GetCurrentProcess().Descendants;
  

• Suspend or resume a process

  using Process process = Process.GetProcessById(pid)
  bool isSuspended = process.Suspended;
  process.Suspended = true;
  process.Suspended = false;
  

• Detect if a process is elevated (running as administrator)

  bool isElevated = Process.GetCurrentProcess().IsProcessElevated();
  

• Get process command line, even for processes not started by this process

Security

• Determine if the user who ran a process is a member of the Administrators group, and if it's running elevated.

  WindowsIdentity.GetCurrent().AdministratorElevation
  

    ElevatedAdmin
    User is an administrator, and the process is running elevated
    UnelevatedAdmin
    User is an administrator, but the process is not running elevated
    NotAdmin
    User is not an administrator, and cannot run any processes elevated
  

Standby and screensaver

• Reliably detect when computer is entering and exiting standby

  using IStandbyListener standbyListener = new EventLogStandbyListener();
  standbyListener.StandingBy += (_,_) => Console.WriteLine("The computer is entering sleep mode");
  standbyListener.Resumed += (_,_) => Console.WriteLine("The computer woke up from sleep mode");
  

• Kill the running screensaver

  new ScreensaverKiller().KillScreensaver();
  

Storage

• Get a file's size on disk. This can be larger than the file's intrinsic size because of cluster size rounding up, or it can be smaller due to NTFS compression or sparse (e.g. partially downloaded) files.

  ulong sizeOnDiskBytes = new FileInfo("filename.txt").LengthOnDisk;
  

UI Automation

• Convert between Win32 window handles, UI Automation elements, and mwinapi window instances

  AutomationElement? automationElement = SystemWindow.ForegroundWindow.ToAutomationElement();
  SystemWindow foreground = foregroundUiaElementd.ToSystemWindow();
  IntPtr? foregroundHwnd = automationElement.ToHwnd();
  

• Easily get all children of a UI Automation element

  IEnumerable<AutomationElement> children = automationElement.Children();
  

• Create a UI Automation property AND or OR condition that doesn't crash if there is only one sub-condition

  IEnumerable<string> allowedNames = ["A"];
  automationElement.FindFirst(TreeScope.Children, UIAutomationExtensions.SingletonSafePropertyCondition(AutomationElement.NameProperty, false, allowedNames));
  

• Find a child or descendant UI Automation element and wait if it doesn't immediately exist, instead of returning null, to prevent UI rendering race conditions

  AutomationElement? a = automationElement.WaitForFirst(TreeScope.Children, new PropertyCondition(AutomationElement.NameProperty, "A"), TimeSpan.FromSeconds(30), cancellationToken);
