PurePowerShell post – GUI Pause to give user choice to continue or abort a PowerShell script execution

<# Put the below between the #BEGIN PAUSE DEFINITION# and #END PAUSE DEFINITION# tags at the beginning of your script, and whenever you need a pause, just type the "GUIPAUSE" word to call the function when you need to give user the choice to continue or abort a script execution

If you ever need to customize the pause window, use the following format:

  GUIPAUSE -Message "MyMessage" -Title "MyTitle"

 -------------------------- EXAMPLE 1 --------------------------

 GUIPAUSE

 => launches the Pause window with "OK" and "Cancel" to continue or abort the script

  -------------------------- EXAMPLE 2 --------------------------

  GUIPAUSE -Message "I Love PowerShell ..." -Title "Another Title"

  => same as above with custom message and box title

 #>

######BEGIN PAUSE DEFINITION######

Function GUIPAUSE ($Message = "Click OK to continue or CANCEL to exit script", $Title = "Continue or Cancel") {

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

    $MsgBox = [System.Windows.Forms.MessageBox]

    $Decision = $MsgBox::Show($Message,$Title,"OkCancel", "Information")

    If ($Decision -eq "Cancel") {exit}

}

######END PAUSE DEFINITION######
