This chapter reviews:

1. All spaces have properties, methods, and events

2. The format of the properties and methods of the access space are: space name, a dot number, properties and methods, provide parameters when needed

3. When the program runs, the interaction between the user and the interface triggers events

4. Show user forms with Show method

5. Use the Initialize event to set values and add controls before the window is displayed

The 11th Chapter MicroStation object Model--object

Provides the object model of the library, the Object Browser in VBA is most helpful, and VBA also includes other tools that can help you develop, such as adding monitoring and automatic list features

The 12th Chapter MicroStation Object Model--Enumeration enumeration

Advantages of enumerations: it is easier to see the results of the required parameters when parsing the code.

Enumeration member names often begin with an enumeration name or an abbreviated version of an enumeration name. For example, MSDDESIGNFILEFORMATDWG is the beginning of the enumeration name "Msddesignfileformat".

All enumerations in MicroStation begin with the specified three-character "MSD", and all members begin with "MSD"

14th Chapter MicroStation Object Model--event

Objects have methods, properties, and events.

15th. Adding content to a document

Use a colon (:) put two lines of code on one line. Placing the same vertex assignment on one line also increases the readability of the Code
