  1. Start Microsoft Visual Studio .NET 2002 or Visual Studio .NET 2003. On the File menu, click New and then click Project. Select Windows Application from the Visual Basic Projects types. Form1 is created by default.
  2. Add a reference to the Microsoft PowerPoint Object Library and the Microsoft Graph Object Library. To do this, follow these steps:
    1. On the Project menu, click Add Reference.
    2. On the COM tab, locate the
      Microsoft PowerPoint Object Library, and then click
      Select. Also locate the Microsoft Graph Object Library, and then click Select.

      Note: Microsoft Office 2003 and later versions of Microsoft Office includes Primary Interop Assemblies (PIAs). Microsoft Office XP does not include PIAs, but they may be downloaded.

    3. Click OK in the Add References dialog box to accept your selections.
  3. On the View menu, select
    Toolbox to display the Toolbox and add a button to Form1.
  4. Double-click Button1. The code window for the form appears.
  5. In the code window, locate the following code
        Private Sub Button1_Click(ByVal sender As System.Object, _
    ByVal e As System.EventArgs) Handles Button1.Click

    End Sub
    Replace with the following code:
        Private Sub Button1_Click(ByVal sender As System.Object, _
    ByVal e As System.EventArgs) Handles Button1.Click

    Const sTemplate = _
    "C:\Program Files\Microsoft Office\Templates\Presentation Designs\Blends.pot"
    Const sPic = "C:\WINNT\Soap Bubbles.bmp"

    'Start Powerpoint and make its window visible but minimized.
    oApp = New PowerPoint.Application()
    oApp.Visible = True
    oApp.WindowState = PowerPoint.PpWindowState.ppWindowMinimized

    'Create a new presentation based on the specified template.
    oPres = oApp.Presentations.Open(sTemplate, , , True)

    'Build Slide #1:
    'Add text to the slide, change the font and insert/position a
    'picture on the first slide.
    oSlide = oPres.Slides.Add(1, PowerPoint.PpSlideLayout.ppLayoutTitleOnly)
    With oSlide.Shapes.Item(1).TextFrame.TextRange

    End With
    oSlide.Shapes.AddPicture(sPic, False, True, 150, 150, 500, 350)
    oSlide = Nothing

    'Build Slide #2:
    'Add text to the slide title, format the text. Also add a chart to the
    'slide and change the chart type to a 3D pie chart.
    oSlide = oPres.Slides.Add(2, PowerPoint.PpSlideLayout.ppLayoutTitleOnly)
    With oSlide.Shapes.Item(1).TextFrame.TextRange
    .Text = "My Chart"

    .Font.Size = 48
    End With
    Dim oChart As Graph.Chart
    oChart = oSlide.Shapes.AddOLEObject(150, 150, 480, 320, _

    Dim oShape As PowerPoint.Shape
    oShape = oSlide.Shapes.AddTextEffect(Office.MsoPresetTextEffect.msoTextEffect27, _
    "The End", "Impact", 96, False, False, 230, 200)
    oShape.Shadow.ForeColor.SchemeColor = PowerPoint.PpColorSchemeIndex.ppForeground
    oShape.Shadow.Visible = True
    oShape.Shadow.OffsetX = 3
    oShape.Shadow.OffsetY = 3
    oShape = Nothing
    oSlide = Nothing

    'Modify the slide show transition settings for all 3 slides in
    'the presentation.
    Dim SlideIdx(3) As Integer
    SlideIdx(0) = 1
    SlideIdx(1) = 2
    SlideIdx(2) = 3
    With oPres.Slides.Range(SlideIdx).SlideShowTransition
    .AdvanceOnTime = True
    .AdvanceTime = 3
    .EntryEffect = PowerPoint.PpEntryEffect.ppEffectBoxOut
    End With
    Dim oSettings As PowerPoint.SlideShowSettings
    oSettings = oPres.SlideShowSettings
    oSettings.StartingSlide = 1
    oSettings.EndingSlide = 3

    'Prevent Office Assistant from displaying alert messages.
    bAssistantOn = oApp.Assistant.On
    oApp.Assistant.On = False

    'Run the slide show and wait for the slide show to end.
    oSettings.Run()
    Do While oApp.SlideShowWindows.Count >= 1
    System.Windows.Forms.Application.DoEvents()
    Loop
    oSettings = Nothing

    'Reenable Office Assisant, if it was on.
    If bAssistantOn Then
    oApp.Assistant.On = True
    oApp.Assistant.Visible = False
    End If

    'Close the presentation without saving changes and quit PowerPoint.
    oPres.Saved = True
    oPres.Close()
    oPres = Nothing
    oApp.Quit()
    oApp = Nothing
    GC.Collect()
    End Sub
    Note In this code, the sTemplate and sPic constants represent the full path and filename to a PowerPoint template and a picture, respectively. Modify these paths as needed to use a template or picture that is installed on your system.
  6. Add the following code to the top of Form1.vb:
    Imports Office = Microsoft.Office.Core
    Imports Graph = Microsoft.Office.Interop.Graph
    Imports PowerPoint = Microsoft.Office.Interop.PowerPoint
  7. Press F5 to build and then run the program.
  8. Click Button1 on the form to create and then show a PowerPoint presentation.
