Forced function to always return an array. Filter is now a parameter that can be specified to control behavior. Changed InitialDirectory to default to $pwd and to give an alias of 'Path' which is commonly used parameter name. Also changed syntax to Add-Type -AssemblyName to conform with Powershell 2+ and to be more "Powershelly". #> #region parameter [CmdletBinding(ConfirmImpact='None')] Param( [parameter(Mandatory=$false)] [alias('Path')] [string] $InitialDirectory = "$pwd", #default [parameter(Mandatory=$false)] [alias('Overwrite')] [bool] $OverwritePrompt = $true, #default [parameter()] [string] $Filter = 'All files|*.*', #default [parameter()] [string] $Title, [parameter()] [switch] $AddExtension, [parameter()] [string] $DefaultExt ) #endregion parameter begin { } process { Add-Type -AssemblyName System.Windows.Forms $SaveFileDialog = New-Object -typename System.Windows.Forms.SaveFileDialog $SaveFileDialog.InitialDirectory = $InitialDirectory $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) } else { # nothing to return } } end { } } #end function Get-SaveFile |
