function Show-LoadingSplash { <# .SYNOPSIS Displays a responsive loading splash screen with progress tracking. .DESCRIPTION Creates a non-blocking loading splash screen that runs in a separate runspace. Provides smooth progress animation and status updates without freezing the UI. .PARAMETER Message Initial status message to display. Default: "Initializing..." .PARAMETER Title Window title text. Default: "PIM Activation" .OUTPUTS PSCustomObject with UpdateStatus() and Close() methods for controlling the splash screen. .EXAMPLE $splash = Show-LoadingSplash -Message "Loading configuration..." $splash.UpdateStatus("Processing items...", 50) $splash.Close() #> [CmdletBinding()] param( [string]$Message = "Initializing...", [string]$Title = "PIM Activation" ) # Synchronized hashtable for cross-runspace communication $syncHash = [hashtable]::Synchronized(@{ Message = $Message Progress = 0 TargetProgress = 0 ShouldClose = $false Form = $null StatusLabel = $null ProgressBar = $null IsDisposed = $false }) # Create STA runspace for the UI $runspace = [runspacefactory]::CreateRunspace() $runspace.ApartmentState = "STA" $runspace.ThreadOptions = "ReuseThread" $runspace.Open() $runspace.SessionStateProxy.SetVariable("syncHash", $syncHash) # Create PowerShell instance $powershell = [powershell]::Create() $powershell.Runspace = $runspace # UI creation script [void]$powershell.AddScript({ Add-Type -AssemblyName System.Windows.Forms Add-Type -AssemblyName System.Drawing # Main form $form = New-Object System.Windows.Forms.Form -Property @{ Text = "PIM Activation" Size = [System.Drawing.Size]::new(400, 150) StartPosition = 'CenterScreen' FormBorderStyle = 'FixedDialog' BackColor = [System.Drawing.Color]::White TopMost = $true ShowInTaskbar = $false MaximizeBox = $false MinimizeBox = $false } # Status label $statusLabel = New-Object System.Windows.Forms.Label -Property @{ Text = $syncHash.Message Font = [System.Drawing.Font]::new("Segoe UI", 10) Location = [System.Drawing.Point]::new(10, 20) Size = [System.Drawing.Size]::new(380, 30) TextAlign = 'MiddleCenter' ForeColor = [System.Drawing.Color]::FromArgb(32, 31, 30) Anchor = [System.Windows.Forms.AnchorStyles]::Top -bor [System.Windows.Forms.AnchorStyles]::Left -bor [System.Windows.Forms.AnchorStyles]::Right } $form.Controls.Add($statusLabel) # Progress bar $progressBar = New-Object System.Windows.Forms.ProgressBar -Property @{ Location = [System.Drawing.Point]::new(20, 60) Size = [System.Drawing.Size]::new(340, 30) Style = [System.Windows.Forms.ProgressBarStyle]::Continuous Minimum = 0 Maximum = 100 Value = 0 ForeColor = [System.Drawing.Color]::FromArgb(0, 103, 184) BackColor = [System.Drawing.Color]::FromArgb(242, 242, 242) Anchor = [System.Windows.Forms.AnchorStyles]::Top -bor [System.Windows.Forms.AnchorStyles]::Left -bor [System.Windows.Forms.AnchorStyles]::Right } $form.Controls.Add($progressBar) # Store UI references $syncHash.Form = $form $syncHash.StatusLabel = $statusLabel $syncHash.ProgressBar = $progressBar $form.Add_FormClosed({ $syncHash.IsDisposed = $true }) # Update timer for smooth animations $timer = New-Object System.Windows.Forms.Timer $timer.Interval = 20 $timer.Add_Tick({ # Update status text if ($syncHash.StatusLabel.Text -ne $syncHash.Message) { $syncHash.StatusLabel.Text = $syncHash.Message } # Animate progress bar $currentValue = $syncHash.ProgressBar.Value $targetValue = [Math]::Min($syncHash.TargetProgress, 100) if ($currentValue -ne $targetValue) { $diff = $targetValue -
