在修改PPT时，想修改一下字体格式，试了一下，Office没发现有直接修改的功能，如果手工修改，我的天！三百多页，卡得要死，只好用VBA宏实现了。代码如下：

Sub ChangeTextFont()
	Set pages = ActivePresentation.Slides.Range
	pageCount = pages.Count

	'第一页和最后一页跳过
	For i = 2 To pageCount - 1
		DoEvents
		ActiveWindow.View.GotoSlide Index:=i
		shapeCount = ActiveWindow.Selection.SlideRange.Shapes.Count

		For j = 1 To shapeCount
			ActiveWindow.Selection.SlideRange.Shapes(j).Select
			shapeType = ActiveWindow.Selection.SlideRange.Shapes(j).Type

			'1  - 自选图形
			'7  - 公式
			'13 - 图片
			'14 - 占位符
			'15 - 艺术字
			'17 - 文本框
			'19 - 表格
			'Debug.Print shapeType
			Select Case shapeType
			Case 1, 14, 17
				Set txtRange = ActiveWindow.Selection.ShapeRange.TextFrame.TextRange
				txtRange.Select

				If txtRange.Text <> "" Then
					'设置字体为宋体, 24号
					With txtRange.Font
						.Name = "宋体"
						.Size = 24
					End With

					'设置段落格式为1.3倍行距
					With txtRange.ParagraphFormat
						.SpaceWithin = 1.3
					End With
				End If
			Case 7, 13, 15
			Case 19
			End Select
		Next j
	Next i
End Sub

另外，推荐可以使用 PPT统一字体工具V3.00 http://blog.sina.com.cn/u/2135968783
