File Selection Input Window

Sometimes in my scripting ways I need to solicit a location from a user with for reading or writing data. Below is a simple function I have used when I need a user to select a Comma Separated Values file. It creates a simple dialogue box showing .CSV files in a particular location. It will either return the selected file name or an error. It is a simple starting point that can be expanded upon as needed.

Function Select-FileWindow

{

      param(

      [string]$Title = "Select CSV",

      [string]$Directory = "C:",

      [string]$Filter = "CSV Files (*.csv)|*.csv"

      )

     

      [System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms") | Out-Null

      $objForm = New-Object System.Windows.Forms.OpenFileDialog

      $objForm.InitialDirectory = $Directory

      $objForm.Filter = $Filter

      $objForm.Title = $Title

      $objForm.ShowHelp = $true

      $Show = $objForm.ShowDialog()

      If ($Show -eq "OK")

      {

            Return $objForm.FileName

      }

      Else

      {

            Write-Error "Operation cancelled by user."

      }

}
