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.

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
