function Invoke-CallbackMenu { <# .SYNOPSIS Calls a GUI window to pick the contexts for a specific server. .DESCRIPTION Calls a GUI window to pick the contexts for a specific server. This is used when invoking Set-AdmfContext with the (hidden) -Callback parameter. It is designed to be triggered automatically when trying to manage a forest / domain that has not yet had its context defined. Note: This makes it critical to define a context first when doing unattended automation. .PARAMETER Server The server / domain being connected to. Used for documentation purposes, as well as to potentially determine initial checkbox state. .PARAMETER Credential The credentials to use for this operation. .EXAMPLE PS C:\> Invoke-CallbackMenu -Server contoso.com Shows the context selection menu for the domain contoso.com #> [Diagnostics.CodeAnalysis.SuppressMessageAttribute("PSUseShouldProcessForStateChangingFunctions", "")] [CmdletBinding()] param ( [Parameter(Mandatory = $true)] [string] $Server, [pscredential] $Credential ) begin { #region Utility Functions function New-CheckBox { [CmdletBinding()] param ( $ContextObject, $Parent ) $column = $Parent.Controls.Count % 2 $row = [math]::Truncate(($Parent.Controls.Count / 2)) $checkbox = [System.Windows.Forms.CheckBox]::new() $checkbox.Width = 200 $checkbox.Height = 20 $checkbox.AutoSize = $false $checkbox.Location = [System.Drawing.Point]::new((210 * $column + 15), (25 * $row + 15)) $checkbox.Text = $ContextObject.Name $checkbox.Font = 'Microsoft Sans Serif,10' $null = $Parent.Controls.Add($checkbox) $tooltip = [System.Windows.Forms.ToolTip]::new() $tooltip.ToolTipTitle = $ContextObject.Name $tooltipText = $ContextObject.Description if ($ContextObject.Prerequisites.Count -gt 0) { $tooltipText += "`nPrerequisites: $($ContextObject.Prerequisites -join ', ')" } if ($ContextObject.MutuallyExclusive.Count -gt 0) { $tooltipText += "`nMutually exclusive with: $($ContextObject.MutuallyExclusive -join ', ')" } $tooltip.SetToolTip($checkbox, $tooltipText) $checkbox.Add_CheckedChanged({ Update-Checkbox }) $checkbox } function Update-Checkbox { [CmdletBinding()] param () # Exemption: Accessing superscope variables directly.
