hashmap dict enum在VBA中的不同点

在解决一个两组数据的匹配的问题的时候，想到在算法图解中介绍的hashmap的算法，如果将这两组数据都作为数组来处理，其效率应该不会比hashmap的映射来的更快，从O(n)变为O(1)的问题

然后想到了dict的方法，但VBA也支持enum，想要知道两种方法那种效率更高。

PPT中对象的层次关系

application-presentations-slides-shapes

Shapes-ShapeRange-Shape

• Shapes collection to creae shapes and when you want to iterate all the shapes on a slide
• you use the Shape object when you want to modify a single shape
• you use the ShapeRange collection when you want to modify shapes the same way you can work with multiple selected shapes in the user interface.

Shape-table-cell

table 隶属于 Shape

'create table in shapes
ActivePresentation.Slide(2).Shapes _
  .AddTable NumRows:=3, NumColumns:=4, Left:=10, _
  Top:=10, Width:=288, Height:=288

'Useing HasTable to test whether a shape is tabel

'Table 的rows属性可以进行Cells遍历
shape(i).Table.rows(j).cells

MsoShapeType Enumeration

这里列举了所有的shape的类型，通过shape.type获得类型具体如下表

获取地址

application.path 获得应用软件的地址，特别的在PPT中为PowerPoint应用的地址
C:\Program Files (x86)\Microsoft Office\Office15
presentation.path 获得ppt文档的地址
D:\file1\file2\target_file

Save\SaveAs\SaveCopyAs的区别

Save在当前文件目录下保存
SaveAs在当前目录下或目标目录下保存文件，运行的文件保存后名字自动变更为目标文件名（含地址）
SaveCopyAs必须带参数，保存后，当前的运行的文件不会替换为保存的目标文件，相当于该保存是作为对当前文件的备份

Collection object的区别

Collection 也是一个对象（Object）
Link1

Collection 与Dictionary的区别

Link
Dictionary的效率比Collection的效率更高

DocumentWindow

Slides(?)的参数

在slides的collection中，其参数如果使用数字1,2,3,4,ect. 代表PPT中幻灯片的显示位置
如果使用"slide名"则根据slide.Name属性来调用该Slide
link1

Slide

.Hyperlinks属性

Returns a Hyperlinks collection that represents all the hyperlinks on the specified slide. Read-only.

.Master属性

Returns a Master object that represents the slide master. Read-only.

.SlideId属性

Returns a unique ID number for the specified slide. Read-only.

using the FindBySlideID method with the slide's ID number can be a more reliable way to return a specific Slide object from a Slides collection than using the Item method with the slide's index number.

.SlideId /.SlideIndex /.SlideNumber的区别

???疑问点

• 从外部黏贴的机制
• 在ppt内部复制黏贴的注意点
