named "test.ppt" is open. In your code, replace this file name with the name of
your presentation.

Sample Visual Basic Procedures
------------------------------

     Sub Driver()

        Dim IsOpen As Boolean

        ' Check to see whether test.ppt is open.
        IsOpen = IsPresentationOpen("test.ppt")

        ' Process the return value from IsPresentationOpen.
        If IsOpen = True Then
           MsgBox "The presentation is open.", vbInformation
        Else
           MsgBox "The Presentation is not open.", vbInformation
        End If

     End Sub

     ' Function Name: IsPresentationOpen()
     ' Arguments:     A string that represents the name of the presentation.
     '                The string can include the full path or just the
     '                presentation name.
     ' Returns:       True if the presentation is open
     '                False if the presentation is not open

     Function IsPresentationOpen(strPresName As String) As Boolean

        ' An object reference to a presentation.
        Dim oPresObject As Presentation

        Dim boolIsFullPath As Boolean

        ' Check to see whether the full path was passed.
        If (InStr(1, strPresName, ":\")) = 0 Then
           boolIsFullPath = False
        Else
           boolIsFullPath = True
        End If

        ' Loop through the open presentations.
        For Each oPresObject In PowerPoint.Presentations

           If boolIsFullPath = True Then

              ' Check for a match.
              If (StrComp(oPresObject.FullName, _
                       strPresName, _
                       vbTextCompare) = 0) Then

                 IsPresentationOpen = True
                 Exit Function
              End If

           Else

              ' Check for a match.
              If (StrComp(oPresObject.Name, _
                       strPresName, _
                       vbTextCompare) = 0) Then
                 IsPresentationOpen = True
                 Exit Function
              End If

           End If

        Next oPresObject

        ' No match found.
        IsPresentationOpen = False

     End Function
