标题: 用VB代码实现PPT课件的交互功能 [打印本页] 作者: etthink 时间: 2008-11-28 19:07 标题: 用VB代码实现PPT课件的交互功能 本文介绍如何使用 Microsoft Visual Basic 使 Microsoft PowerPoint 在 Microsoft Office2003、Microsoft Office XP Developer 和 Microsoft Office 2000 Developer中自动运行。
通过使用 PowerPoint 中的自动运行功能，您可以以编程方式打印、显示幻灯片及执行以交互式执行的大多数事情。按照以下步骤构建并运行一个 Visual Basic 自动运行示例：
创建一个新的标准 EXE 项目。Form1 是默认创建的窗体。
向默认的窗体添加一个 CommandButton。
从项目菜单上，单击引用，添加 Microsoft PowerPoint 8.0 对象库和 Microsoft Office 8.0 对象库。对于 Office 2000，类型库的版本是 9.0。对于 Office 2002，类型库的版本是 10.0。对于 Microsoft Office 2003，类型库的版本是 11.0。
将以下代码添加到您的窗体代码窗口中：
Private Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)
Private Sub Command1_Click()
' Start PowerPoint.
Dim ppApp As PowerPoint.Application
Set ppApp = CreateObject("Powerpoint.Application")
' Make it visible.
ppApp.Visible = True
' Add a new presentation.
Dim ppPres As PowerPoint.Presentation
Set ppPres = ppApp.Presentations.Add(msoTrue)
' Add a new slide.
Dim ppSlide1 As PowerPoint.Slide
Set ppSlide1 = ppPres.Slides.Add(1, ppLayoutText)
' Add some text.

ppSlide1.Shapes(2).TextFrame.TextRange.Text = "Automating Powerpoint is easy" & vbCr & "Using Visual Basic is fun!"
' Add another slide, with a chart.
Dim ppSlide2 As PowerPoint.Slide
Set ppSlide2 = ppPres.Slides.Add(2, ppLayoutTextAndChart)
' Add some text.
ppSlide2.Shapes(1).TextFrame.TextRange.Text = "Slide 2's topic"
ppSlide2.Shapes(2).TextFrame.TextRange.Text = "You can create and use charts in your Powerpoint slides!"
' Add a chart in the same location as the old one.

Dim ppSlide3 As PowerPoint.Slide
Set ppSlide3 = ppPres.Slides.Add(3, ppLayoutOrgchart)
' Add some text.
ppSlide3.Shapes(1).TextFrame.TextRange.Text = "The rest is only limited by your Imagination"

' Setup slide show properties.
With ppPres.Slides.Range.SlideShowTransition
.EntryEffect = ppEffectRandom
.AdvanceOnTime = msoTrue
.AdvanceTime = 5 ' 5 seconds per slide
End With
' Prepare and run the slide show.
With ppPres.SlideShowSettings

.RangeType = ppShowAll
.AdvanceMode = ppSlideShowUseSlideTimings
