Forced function to always return an array. Filter is now a parameter that can be specified to control behavior. Changed Path to default to $pwd and to give an alias of 'Path' which is commonly used parameter name. Also changed syntax to Add-Type -AssemblyName to conform with Powershell 2+ and to be more "Powershelly". # Source: https://gallery.technet.microsoft.com/ISE-Color-Theme-Cmdlets-24905f9e # get-help about_ISE-Color-Theme-Cmdlets for more information #> #region parameter [CmdletBinding(ConfirmImpact = 'None')] Param( [Alias('InitialDirectory')] [string] $Path = "$pwd", #default [Alias('Overwrite')] [bool] $OverwritePrompt = $true, #default [string] $Filter = 'All files|*.*', #default [string] $Title, [switch] $AddExtension, [string] $DefaultExt ) #endregion parameter begin { Write-Verbose -Message "Starting [$($MyInvocation.Mycommand)]" } process { Add-Type -AssemblyName System.Windows.Forms $SaveFileDialog = New-Object -TypeName System.Windows.Forms.SaveFileDialog $SaveFileDialog.InitialDirectory = $Path $SaveFileDialog.Filter = $Filter $SaveFileDialog.OverwritePrompt = $OverwritePrompt if ($Title) { $SaveFileDialog.Title = $Title } if ($DefaultExt) { $SaveFileDialog.DefaultExt = $DefaultExt } if ($AddExtension) { $SaveFileDialog.AddExtension = $true } $Result = $SaveFileDialog.ShowDialog() # needed to play around to force PowerShell to return an array. if ($Result -eq 'OK') { [array] $ReturnArray = $SaveFileDialog.FileName Write-Output -InputObject (, $ReturnArray) } } end { Write-Verbose -Message "Ending [$($MyInvocation.Mycommand)]" } } |
