Overview

WinUtil is a sophisticated Windows utility application built entirely in PowerShell, demonstrating an innovative approach to creating professional desktop applications using native Windows technologies. The application showcases advanced PowerShell scripting combined with WPF (Windows Presentation Foundation) to deliver a modern, responsive GUI experience.

Core Technologies

Primary Framework Stack

Technology	Purpose	Implementation
PowerShell	Core application logic and scripting	Single `.ps1` file containing all functionality
WPF (Windows Presentation Foundation)	GUI framework	Native Windows desktop application framework
XAML	UI definition and layout	Declarative markup for user interface design
Windows Forms	Dialog components	File/folder browser dialogs
.NET Framework	Runtime environment	Leverages .NET assemblies through PowerShell

Assembly Loading

# Core WPF Framework
Add-Type -AssemblyName PresentationFramework

# Additional dialog components  
Add-Type -AssemblyName System.Windows.Forms

GUI Framework Architecture

XAML-Based User Interface

The application uses a sophisticated XAML definition embedded as a PowerShell here-string:

$inputXML = @'
<Window x:Class="WinUtility.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        WindowStartupLocation="CenterScreen"
        UseLayoutRounding="True"
        WindowStyle="None"
        Width="Auto"
        Height="Auto"
        MinWidth="800"
        MinHeight="600"
        Title="WinUtil">
    <WindowChrome.WindowChrome>
        <WindowChrome CaptionHeight="0" CornerRadius="10"/>
    </WindowChrome.WindowChrome>
    <!-- Extensive XAML definition continues... -->
'@

Runtime XAML Processing

# Parse and load XAML at runtime
[xml]$XAML = $inputXML
$reader = (New-Object System.Xml.XmlNodeReader $xaml)
$sync["Form"] = [Windows.Markup.XamlReader]::Load($reader)

# Bind named controls to PowerShell variables
$xaml.SelectNodes("//*[@Name]") | ForEach-Object {
    $sync["$($psitem.Name)"] = $sync["Form"].FindName($psitem.Name)
}

Advanced Features

🧵 Multi-Threading Architecture

# Runspace pool for background operations
$maxthreads = [int]$env:NUMBER_OF_PROCESSORS
$InitialSessionState = [System.Management.Automation.Runspaces.InitialSessionState]::CreateDefault()

# Create runspace pool
$sync.runspace = [runspacefactory]::CreateRunspacePool(
    1,                      # Minimum thread count
    $maxthreads,            # Maximum thread count  
    $InitialSessionState,   # Initial session state
    $Host                   # Machine to create runspaces on
)

# Execute background tasks
function Invoke-WPFRunspace {
    $script:powershell = [powershell]::Create()
    $script:powershell.AddScript($ScriptBlock)
    $script:powershell.RunspacePool = $sync.runspace
    $script:handle = $script:powershell.BeginInvoke()
}

🎨 Dynamic Theme System

# Theme switching functionality
function Set-WinutilTheme {
    param([string]$currentTheme)
    
    function Set-ThemeResourceProperty {
        param($Name, $Value, $Type)
        
        switch ($Type) {
            "ColorBrush" { 
                $sync.Form.Resources[$Name] = [Windows.Media.BrushConverter]::new().ConvertFromString($Value)
            }
            "Color" {
                $sync.Form.Resources[$Name] = [Windows.Media.ColorConverter]::new().ConvertFromString($Value)  
            }
            # Additional type handlers...
        }
    }
}

# Automatic system theme detection
$sync.Form.Add_Loaded({
    $interopHelper = New-Object System.Windows.Interop.WindowInteropHelper $sync.Form
    $hwndSource = [System.Windows.Interop.HwndSource]::FromHwnd($interopHelper.Handle)
    $hwndSource.AddHook({
        # Listen for Windows theme change events
        # Update application theme accordingly
    })
})

🎯 Event-Driven Architecture

# Automatic event binding for UI controls
$sync.keys | ForEach-Object {
    if($sync.$psitem) {
        if($($sync["$psitem"].GetType().Name) -eq "Button") {
            $sync["$psitem"].Add_Click({
                [System.Object]$Sender = $args[0]
                Invoke-WPFButton $Sender.name
            })
        }
    }
}
