建立 Microsoft PowerPoint 的自動化用戶端
啟動 Microsoft Visual Studio .NET 2002 或 Visual Studio .NET 2003。 在 [檔案] 功能表上,按一下 [新增],然後按一下 [專案]。 從 Visual Basic 專案類型中選取 [Windows 應用程式]。 根據預設,會建立 Form1。
新增 Microsoft PowerPoint 物件程式庫和 Microsoft Graph 物件程式庫的參考。 如果要執行這項操作,請依照下列步驟執行:
- 按一下 [專案] 功能表上的 [加入參考]。
- 在 [ COM] 索引卷 標上,找出 [Microsoft PowerPoint 物件程式庫],然後按一下 [ 選取]。 另請找出 Microsoft Graph 物件程式庫,然後按一下 [ 選取]。
注意 Microsoft Office 2003 和更新版本的 Microsoft Office 包含主要 Interop 元件 (PIA) 。 Microsoft Office XP 不包含 PIA,但可能會下載。
按一下 [新增參考] 對話方塊中的 [確定] 以接受您的選擇。
在 [ 檢視] 功能表上,選取 [ 工具箱 ] 以顯示 [工具箱],並將按鈕新增至 Form1。
按兩下 Button1。 表單的程式碼視窗隨即出現。
在程式碼視窗中,找出下列程式碼
Private Sub Button1_Click(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles Button1.Click End Sub
將 取代為下列程式碼:
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" Dim oApp As PowerPoint.Application Dim oPres As PowerPoint.Presentation Dim oSlide As PowerPoint.Slide Dim bAssistantOn As Boolean '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 .Text = "My Sample Presentation" .Font.Name = "Comic Sans MS" .Font.Size = 48 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.Name = "Comic Sans MS" .Font.Size = 48 End With Dim oChart As Graph.Chart oChart = oSlide.Shapes.AddOLEObject(150, 150, 480, 320, _ "MSGraph.Chart.8").OLEFormat.Object oChart.ChartType = Graph.XlChartType.xl3DPie oChart = Nothing oSlide = Nothing 'Build Slide #3: 'Add a text effect to the slide and apply shadows to the text effect. oSlide = oPres.Slides.Add(3, PowerPoint.PpSlideLayout.ppLayoutBlank) oSlide.FollowMasterBackground = False 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
注意 在此程式碼中,sTemplate 和 sPic 常數分別代表 PowerPoint 範本和圖片的完整路徑和檔案名。 視需要修改這些路徑,以使用安裝在系統上的範本或圖片。
將下列程式碼新增至 Form1.vb 的頂端:
Imports Office = Microsoft.Office.Core Imports Graph = Microsoft.Office.Interop.Graph Imports PowerPoint = Microsoft.Office.Interop.PowerPoint
按 F5 建置,然後執行程式。
按一下表單上的 Button1 以建立 PowerPoint 簡報,然後顯示 PowerPoint 簡報。
