用 VBA 实现在 PPT 最下边加个进度条,方便查看进行到总长度的多少,
抓住了听讲人的心理:“啥时候才能讲完啊?”
进度条只能体现已播放的幻灯片张数,不能用于计时。
打开 PPT,按 Alt+F8 新建个宏,随便取个宏名,不用改宏作用区域,
点“创建”,删除模块里的内容,把代码复制过去。
(按 Alt+F11 之后插入模块也可以)
进度条宏的作者是水木社区的dukenuke。
Sub ProgressBar() ' by dukenuke@newsmth.net ' Sun Jul 11 00:06:13 2010 Dim mySlides As Slides Dim pageBar As ShapeRange Dim pageSHower As Shape Dim pageWidth, pageHeight, pageStep Set mySlides = Application.ActivePresentation.Slides pageWidth = Application.ActivePresentation.SlideMaster.Width pageHeight = Application.ActivePresentation.SlideMaster.Height pageStep = pageWidth / mySlides.Count On Error Resume Next For i = 2 To mySlides.Count Set pageBar = mySlides.Item(i).Shapes.Range(Array()) Set pageBar = _ mySlides.Item(i).Shapes.Range(Array("RectanglePageNum")) If IsNull(pageBar) Or pageBar.Count = 0 Then GoTo newBar Set pageSHower = pageBar.Item(1) GoTo nextPage newBar: Set pageSHower = mySlides.Item(i).Shapes.AddShape( _ msoShapeRectangle, 0, _ pageHeight - 3, i * pageStep, 3) pageSHower.Name = "RectanglePageNum" nextPage: pageSHower.Fill.ForeColor.RGB = RGB(179, 162, 199) pageSHower.Line.Visible = msoFalse pageSHower.Width = i * pageStep pageSHower.Top = pageHeight - 3 pageSHower.Left = 0 pageSHower.Height = 3 Next End Sub
颜色尺寸可以更改,现在的高度是3,在页面最下方,颜色是淡紫色。
PowerPoint 2007/2010 需要另存为带宏的演示文稿,还可以把宏按钮添加
到快速访问工具栏。
开始讲 PPT 前先运行宏(按 Alt+F8 或用快速访问工具栏),运行一次即可,
播放幻灯片时就会自动加上进度条,只有第一页不加,会自动根据当前页
面数刷新进度。
注:增减幻灯片(总页数改变)后要重新运行一次宏。
2010-9-12,对宏进行更新:
Sub ProgressBar() ' bydukenuke@newsmth.net ' Sun Jul 11 00:06:13 2010 ' ' Update by oicu#lsxk.org ' 2010/9/12 20:44 ' 对首页以及隐藏幻灯片进行处理 Dim mySlides As Slides Dim pageBar As ShapeRange Dim pageSHower As Shape Dim pageWidth, pageHeight, pageStep Dim MyArray() As Variant '增加一个数组以便统计隐藏的幻灯片 Dim i, j, k j = 0 k = 0 Set mySlides = Application.ActivePresentation.Slides pageWidth = Application.ActivePresentation.SlideMaster.Width pageHeight = Application.ActivePresentation.SlideMaster.Height ' pageStep = pageWidth / mySlides.Count ReDim MyArray(mySlides.Count, 0) For i = 1 To mySlides.Count'统计隐藏的幻灯片数 If mySlides.Item(i).SlideShowTransition.Hidden = True Then j = j + 1 MyArray(i, 0) = 1 Else MyArray(i, 0) = 0 End If Next '除去首页和隐藏的幻灯片后计算进度条长度增量 If mySlides.Count - 1 - j > 0 Then pageStep = pageWidth / (mySlides.Count - 1 - j) Else pageStep = 0 End If On Error Resume Next For i = 1 To mySlides.Count ' 改为从1开始 k = k + MyArray(i, 0) ' 计算当前隐藏的幻灯片数 Set pageBar = mySlides.Item(i).Shapes.Range(Array()) Set pageBar = _ mySlides.Item(i).Shapes.Range(Array("RectanglePageNum")) If IsNull(pageBar) Or pageBar.Count = 0 Then GoTo newBar Set pageSHower = pageBar.Item(1) GoTo nextPage newBar: Set pageSHower = mySlides.Item(i).Shapes.AddShape( _ msoShapeRectangle, 0, _ pageHeight - 3, i * pageStep, 3) pageSHower.Name = "RectanglePageNum" nextPage: pageSHower.Fill.ForeColor.RGB = RGB(179, 162, 199) pageSHower.Line.Visible = msoFalse ' pageSHower.Width = i * pageStep ' 计算进度条长度时除去首页和隐藏的幻灯片 pageSHower.Width = (i - 1 - k) * pageStep pageSHower.Top = pageHeight - 3 pageSHower.Left = 0 pageSHower.Height = 3 ' 删除首页和隐藏的幻灯片的进度条 If i = 1 Or MyArray(i, 0) = 1 Then pageSHower.Delete Next End Sub
WPS演示安装了vba之后同样可以使用宏制作进度条,不过要修改几个地方才能使用。
Sub ProgressBar() ' by oicu#lsxk.org ' 2010/9/18 22:48 ' For WPS 演示 Dim mySlides As Slides ' Dim pageBar As ShapeRange Dim pageSHower As Shape Dim pageWidth, pageHeight, pageStep Dim MyArray() As Variant '增加一个数组以便统计隐藏的幻灯片 Dim i, j, k j = 0 k = 0 Set mySlides = Application.ActivePresentation.Slides ' pageWidth = Application.ActivePresentation.SlideMaster.Width ' pageHeight = Application.ActivePresentation.SlideMaster.Height ' WPS演示不能取得母板的长宽,改成PageSetup pageWidth = Application.ActivePresentation.PageSetup.SlideWidth pageHeight = Application.ActivePresentation.PageSetup.SlideHeight ReDim MyArray(mySlides.Count, 0) For i = 1 To mySlides.Count ' 统计隐藏的幻灯片数 If mySlides.Item(i).SlideShowTransition.Hidden = True Then j = j + 1 MyArray(i, 0) = 1 Else MyArray(i, 0) = 0 End If Next ' 除去首页和隐藏的幻灯片后计算进度条长度增量 If mySlides.Count - 1 - j > 0 Then pageStep = pageWidth / (mySlides.Count - 1 - j) Else pageStep = 0 End If On Error Resume Next For i = 1 To mySlides.Count ' 改为从1开始 k = k + MyArray(i, 0) ' 计算当前隐藏的幻灯片数 ' WPS演示会自动增加数字在RectanglePageNum名称后面, ' 无法用下面的方法清除原有的进度条!只能循环删除。 For j = 1 To mySlides.Item(i).Shapes.Count If VBA.Left(mySlides.Item(i).Shapes(j).Name, 16) = _ "RectanglePageNum" Then mySlides.Item(i).Shapes(j).Delete Next ' Set pageBar = mySlides.Item(i).Shapes.Range(Array()) ' Set pageBar = _ mySlides.Item(i).Shapes.Range(Array("RectanglePageNum")) ' If IsNull(pageBar) Or pageBar.Count = 0 Then GoTo newBar ' Set pageSHower = pageBar.Item(1) ' GoTo nextPage newBar: ' mso改为kso Set pageSHower = mySlides.Item(i).Shapes.AddShape( _ ksoShapeRectangle, 0, _ pageHeight - 3, i * pageStep, 3) pageSHower.Name = "RectanglePageNum" nextPage: pageSHower.Fill.ForeColor.RGB = RGB(179, 162, 199) pageSHower.Line.Visible = ksoFalse ' mso改为kso ' 计算进度条长度时除去首页和隐藏的幻灯片 pageSHower.Width = (i - 1 - k) * pageStep pageSHower.Top = pageHeight - 3 pageSHower.Left = 0 pageSHower.Height = 3 ' 删除首页和隐藏的幻灯片的进度条 If i = 1 Or MyArray(i, 0) = 1 Then pageSHower.Delete Next End Sub
