SUMMARY
This article provides two sample Microsoft Visual Basic for Applications macros (Sub procedures) that create a backup of the current presentation in Microsoft PowerPoint. The first sample macro generates a backup using a random file name. The second sample macro prompts the user for a file name. Both samples save the file with a .bak extension in the program folder.

This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements.

Sample 1: Saves Backup with Random File Name
Sub Backup Dim lngNumber As Long Dim strString As String Dim strFile As String Dim strFileName As String Dim strPath As String

' Generates random number. lngNumber = Int(Rnd * 100000) ' Converts number to a string. strString = Str(lngNumber) ' Removes blank space from first of number. strFile = Mid(strString, 2, 5) ' Adds first two letters and extension to file name. strFileName = "Bk" & strFile & ".bak" ' Determines path where PowerPoint is stored. strPath = Application.Path ' Saves file with random name and .bak extension. ActivePresentation.SaveAs FileName:=strPath & "\" & strFileName End Sub

Sample 2: Prompts User for File Name for Backup
Sub Backup Dim strFile As String Dim strFileName As String Dim strPath As String

' Prompts for file name. strFile = InputBox("Please enter a file name." & chr(13) _                        & "Spaces may not work correctly.") ' Adds extension to file name. strFileName = strFile & ".bak" ' Determines path where PowerPoint is stored. strPath = Application.Path ' Saves file with the name you input and .bak extension. ActivePresentation.SaveAs FileName:=strPath & "\" & strFileName End Sub
