PPT97: Cannot Embed MIDI Files into a Presentation (250385)

SUMMARY

When you insert a MIDI (.mid) file into a PowerPoint presentation, the file is not embedded into the file structure. Instead an "implied link" is created to the location of the MIDI file.

If the MIDI file is in the same directory as the presentation, the link is stored using only the file name. When PowerPoint loads the file, it searches the same directory where the presentation is located. If the MIDI file is located in another directory, then a fully qualified file path will be created to link to the file.

MORE INFORMATION

You cannot edit the link to the MIDI file through the Links dialog box. You can only modify it with a Visual Basic for Applications (VBA) macro.

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. The following code sample requires that you select the MIDI file before you run the macro. You will be prompted with a dialog box that has the current path for the MIDI file. Just type the path to the new location, and press OK.

Sub MIDIpath()
   On Error GoTo ErrorHandler ' Enable error-handling routine.
   Dim strCurrentLocation As String
   Dim strNewLocation As String
   
   ' This requires that you have selected a MIDI file 
   ' before running this macro
   With ActiveWindow.Selection.ShapeRange
   
      ' Save the current settings for the file's location
      strCurrentLocation = .LinkFormat.SourceFullName
      
      ' Get the new location for the file.
      strNewLocation = InputBox("Enter in new MIDI File Location", _ 
      Default:=strCurrentLocation)
      
      ' If the strNewLocation is not empty, then assign
      ' it to SourceFullName.
      ' NOTE: This does not check to see if the file is
      ' actually in the location specified.
      If strNewLocation <> "" Then 
         .LinkFormat.SourceFullName = strNewLocation
      End If
   End With
Exit Sub ' Exit the subroutine to avoid the error handler.

ErrorHandler: ' Error-handling routine.
   ' Let the user know that no MIDI file was selected.
   MsgBox "No MIDI file has been selected." & vbNewLine & _
   "Please select a MIDI file icon and run this macro again."
End Sub
