The information in this article applies to:
- Microsoft Excel for Windows 95, version 7.0
- Microsoft PowerPoint for Windows 95, version 7.0
SUMMARY
In Microsoft Excel, you can programmatically control Microsoft PowerPoint,
with a Visual Basic for Applications macro that uses OLE automation. To use
the properties and methods in the object library provided by PowerPoint,
you will need to create an object variable using the CreateObject function.
Also, if you are planning to use the built-in constants provided by the
object library, you will need to make a reference to the library.
MORE INFORMATION
The following example creates a presentation, adds graphics and text, and
then runs the slide show.
Microsoft provides examples of Visual Basic for applications procedures for

and Microsoft does not guarantee that it can be used in all situations.
Microsoft does not support modifications of this procedure to suit customer
requirements for a particular purpose.
To run the following macro you will need to perform the following steps:
- Open a new workbook and type the following macro code in a new module
sheet:
Sub PowerPointOLEAutomation()
Dim PPT As Object
Dim Pres As PowerPoint.Presentation
Dim Slide1 As PowerPoint.Slide
Dim Slide2 As PowerPoint.Slide
Dim Slide3 As PowerPoint.Slide
Dim Slide4 As PowerPoint.Slide
Dim i as integer
'creates the PowerPoint Object
Set PPT = CreateObject("powerpoint.application.7")
PPT.AppWindow.Visible = True 'Makes PowerPoint visible
Set Pres = PPT.Presentations.Add 'Adds a blank presentation
'adds a blank slide
Set Slide1 = Pres.Slides.Add(1, ppLayoutBlank)
Set Slide2 = Pres.Slides.Add(2, ppLayoutBlank)
Set Slide3 = Pres.Slides.Add(3, ppLayoutBlank)
Set Slide4 = Pres.Slides.Add(4, ppLayoutBlank)
'you can use universal naming convention (UNC) to point to network share
'adds a graphic image to the slide
'these need to be on a separate line
Slide1.Background.Fill.PresetShaded ppPresetShadeEarlySunset, 1, 1
Slide2.Background.Fill.PresetShaded ppPresetShadeDaybreak, 1, 1
Slide3.Background.Fill.PresetShaded ppPresetShadeMahogany, 1, 1
Slide4.Background.Fill.PresetShaded ppPresetShadeNightfall, 1, 1
For i = 1 To 4 'starts a FOR loop
With Pres.Slides(i)
.Objects.AddTextFrame 5000, 0, 5000 'adds a text frame
Select Case i
Case 1
'enters text into the text frame
.Objects(1).Text = "Today is " & _
Format(Date, "mm/dd/yy")
Case 2
.Objects(1).Text = "This Is Just A Test"
Case 3
.Objects(1).Text = "Please Do Not Be Alarmed"
Case 4
.Objects(1).Text = "Everything Is OK"
End Select
'sets characteristics for the font
With .Objects(1).Text.Font
'screen measurements are done in Twips,
'multiply by 20 to get normal pixel size
.Size = 50 * 20
.Bold = ppTrue
.Shadow = ppTrue
End With
'center aligns the text
.Objects(1).Text.ParaFormat.Alignment = ppAlignCenter
End With
Next i
'copies a chart
ThisWorkbook.Worksheets(1).DrawingObjects("Chart 1").CopyPicture
PPT.ActiveWindow.View.Paste 'pastes the chart
'runs a Slide Show presentation
Pres.SlideShow.Run (ppSlideShowFullScreen)
'clears the object variable
Set PPT = Nothing 'This does not close the application
End Sub
- Create a reference to the PowerPoint object library by activating the
module sheet that contains the macro. Click References on the Tools menu
and select the PowerPoint 7.0 Object Library check box, then click OK.
- In Sheet1 of the workbook that contains the macro code, type the
following:
A1: 1
A2: 2
A3: 3
- Create any type of embedded chart on Sheet1 using the range of A1:A3 as
the source data.
- Run the macro
