Sample Visual Basic Procedure
Sub InsertMultipleSlides

' Used for error trapping. On Error Resume Next Err.Clear

' Change this value to the maximum number of slides you want to     ' create. Const MAX_SLIDES As Long = 250

' Change this to the auto layout you want to use. This value can be     ' any PpSlideLayout constant. Const DEFAULT_AUTO_LAYOUT As Long = ppLayoutText

' Dimension the variables. Dim lLastSlide, i As Long Dim lToCreate, lResult As Long Dim Continue As Boolean Dim strInputPrompt, strResult, strPlural As String

' Initialize the message for the input box. strInputPrompt = "Enter the number of slides you want to create. "

' Loop until valid input. Do

' Ask how many slides do you want to create. strResult = InputBox(strInputPrompt)

' Check for valid input. If strResult = "" Then

' If NULL string returned, stop the macro. End End If

' Convert string to integer. lToCreate = CLng(strResult)

' Check for a type mismatch. If Err.Number <> 0 Then

' Reset the err object. Err.Clear

' Repeat the loop. Continue = False End If

' Check for valid entry. If lToCreate <= MAX_SLIDES And lToCreate > 0 Then Continue = True Else Continue = False End If

' Change the message of input box if invalid entry is made. If Continue = False Then strInputPrompt = "Invalid entry, please enter a value " _ & "between 1 and " & MAX_SLIDES & "." & Chr(13) _ & Chr(13) & strInputPrompt End If

Loop Until Continue = True

' See whether slides or slide is needed in the MsgBox. If lToCreate = 1 Then strPlural = "slide" Else strPlural = "slides" End If

' Ask for confirmation. lResult = MsgBox("Are you sure you want to create " & lToCreate _      & " new " & strPlural & ", at the end of the presentation, using " _         & "the Bulleted List auto layout?", vbYesNo + vbQuestion)

' Find out what the user selected in the message box. If lResult = vbNo Then 'Stop the Macro. End End If

' Get the number of slides in the active presentation. lLastSlide = ActivePresentation.Slides.Count

' Create the new slides. For i = 1 To lToCreate lLastSlide = lLastSlide + 1 ActivePresentation.Slides.Add lLastSlide, DEFAULT_AUTO_LAYOUT

' Find out whether error occurred when creating the new slides. If Err.Number <> 0 Then MsgBox "Unable to add new slides to the presentation. " _ , vbCritical, "Error When Adding New Slides"

' Stop the macro. End End If

Next i

' Display closing message. MsgBox "Successfully added " & lToCreate & " " & strPlural & _ " to the active presentation.", vbInformation, "Macro Done"

End Sub
