NOTE: To use this technique, you must have both PowerPoint and Access installed on your computer. You also need to create a PowerPoint presentation (.ppt). In steps 7 and 9, replace the following file name with the name and path of your file:
C:\Program Files\Microsoft Office\Office\Pptexample.ppt
The following example creates a form with an unbound object frame
control and five command buttons for linking to a PowerPoint
presentation (.ppt) and for moving through its slides.
To display Microsoft PowerPoint slides on a form, follow these steps:
-
In a new Access database, create a new form in Design view.
- Add the following five controls to the form:
Command button
-------------------------
Name: insertShow
Caption: Get Presentation
Enabled: Yes
Command button
-------------------------
Name: frstSlide
Caption: First Slide
Enabled: No
Command button
-------------------------
Name: nextSlide
Caption: Next Slide
Enabled: No
Command button
-------------------------
Name: previousSlide
Caption: Previous Slide
Enabled: No
Command button
-------------------------
Name: lastSlide
Caption: Last Slide
Enabled: No
- Add an unbound object frame control to the form. In the Insert Object box, click the Create New button, select Bitmap Image as the Object Type, and then click OK. Note that the object frame appears as a blank space on the form.
- Display the property sheet for the unbound object frame, and then set its properties as follows:
Unbound Object Frame
--------------------
Name: pptFrame
SizeMode: Zoom
Enabled: Yes
Locked: No
- On the View menu, click Code to open the form module.
- Add the following code to the General Declarations section:
' Initialize variables.
Const firstSlide = 1
Dim arrSlideID() As Long
Dim pptobj As Object
Dim slideindex As Long, slidecount As Long
Sub ErrHandler()
Dim strError As String
Dim errObj As Error
strError = " "
If DBEngine.Errors.Count > 0 Then
For Each errObj In DBEngine.Errors
strError = strError & Format$(errObj.Number)
strError = strError & " : " & errObj.Description
strError = strError & " (" & errObj.Source & ") . "
strError = strError & Chr$(13) & Chr$(10)
Next
MsgBox strError
Else
MsgBox "Error: " & Err & " " & Error
End If
End Sub
- In the Object list click Form and click Load in the Procedure list, and then add the following code:
NOTE: Replace the file name "C:\Program Files\Microsoft Office\Office\Pptexample.ppt"
with the name and path of your Power Point Presentation file.
Private Sub Form_Load()
On Error GoTo Form_Load_Error
Dim i As Integer
Dim holder As Long, present As Object
' Start Powerpoint and open an existing presentation.
holder = Shell("c:\Program Files\Microsoft Office\Office\Powerpnt.exe")
Set pptobj = CreateObject("PowerPoint.Application")
Set present = pptobj.Presentations.Open _
("c:\Program Files\Microsoft Office\Office\Pptexample.ppt")
' Determine the number of slides in the presentation.
slideCount = present.Slides.Count
' Fill an array with all Slide IDs.
ReDim arrSlideID(1 To slideCount)
For i = 1 To slideCount
arrSlideID(i) = present.Slides(i).SlideID
Next i
' Close the presentation.
pptobj.Presentations _
("c:\Program Files\Microsoft Office\Office\Pptexample.ppt").Close
Set present = Nothing
Exit Sub
Form_Load_Error:
ErrHandler
Exit Sub
End Sub
-
Click Form in the Object list and click Unload in the Proc list, and then add the following code:
Private Sub Form_Unload(Cancel As Integer)
On Error GoTo Form_Unload_Error
' Close Powerpoint.
pptobj.Quit
Exit Sub
Form_Unload_Error:
ErrHandler
Exit Sub
End Sub
- Click insertShow in the Object list and click Click in the Proc list, and then add the following code.
NOTE: Replace the file name "C:\Program Files\Microsoft Office\Office\Pptexample.ppt"
with the name and path of your PowerPoint Presentation file.
Private Sub insertShow_Click()

slideindex = FIRSTSLIDE
frstSlide.setfocus
insertShow.enabled=false
Exit sub
insertShow_Click_Error:
ErrHandler
Exit Sub
End Sub
- Click frstSlide in the Object list and click Click in the Proc list, and then add the following code:
Private Sub frstSlide_Click()
On Error GoTo frstSlide_Click_Error
' Set SourceItem property to first slide and create a link.
With pptFrame
.SourceItem = arrSlideID(FIRSTSLIDE)
.Action = acOLECreateLink
End With
slideindex = FIRSTSLIDE
Exit Sub
frstSlide_Click_Error:
ErrHandler
Exit Sub
End Sub
- Click nextSlide in the Object list and click Click in the Proc list, and then add the following code:
Private Sub nextSlide_Click()
On Error GoTo nextSlide_Click_Error
' Determine if current slide is last slide.
If slideindex < slidecount Then
slideindex = slideindex + 1
' Set SourceItem property to next slide and create a link.
With pptFrame

.Action = acOLECreateLink
End With
Else
MsgBox "This is the last slide."
End If
Exit Sub
nextSlide_Click_Error:
ErrHandler
Exit Sub
End Sub
- Click previousSlide in the Object list and click Click in the Proc list, and then add the following code:
Private Sub previousSlide_Click()
On Error GoTo previousSlide_Click_Error
' Determine if current slide is first slide.
If slideindex > FIRSTSLIDE Then
slideindex = slideindex - 1
' Set SourceItem property to previous slide and create a link.
With pptFrame
.SourceItem = arrSlideID(slideindex)
.Action = acOLECreateLink
End With
Else
MsgBox "This is the first slide."
End If
Exit Sub
previousSlide_Click_Error:
ErrHandler
Exit Sub
End Sub
- Click lastSlide in the Object list and click Click in the Proc list, and then add the following code:
Private Sub lastSlide_Click()
On Error GoTo lastSlide_Click_Error
' Set SourceItem property to previous slide and create a link.
With pptFrame

.Action = acOLECreateLink
End With
slideindex = slidecount
Exit Sub
lastSlide_Click_Error:

End Sub
-
Close and save the form module.
-
Switch the form to Form view, and then click the insertShow ("Get Presentation") button.
