The master-slave composite structure (Master/detail) is based on "one-to-many" relationships, providing detailed information in a database table that accesses related records through foreign keywords from another database table. Based on the master-slave composite structure, we can browse the data in one table and give all the record information related to the record in another table. Borland C++builder pro
How do I install a component that I made in BCB 6 or using C + + Builder 2007? I think in the old version of BCB 6 It was clear how to install a component that was built by Component->new Component, and usually if we didn't add a new Package project and add the components ourselves, BCB 6 would preset a set of DCLUSR.BPK for you Install your component, of course you can add a new Package project to join your component, when the component compile finis

I. Definition
Builder mode: separates the construction of a complex object from its representation, so that different representations can be created during the same build process.
Explanation: In the builder mode, you only need to specify the types to be constructed to obtain them, but you do not need

I am not planning to jump into too many details of the design model, because I have already explained a lot of articles and books in detail. So I want to tell you why and when you should consider using the design pattern
Builder mode: The internal representation of a product can be separated from the production process, allowing a construction process to produce a product object with different internal representationsBuilding the UML class diagram of the modal:Class Diagram Relationship Description:Builder role: An abstract interface is given to standardize the construction of each component of the Product object. Typically, this interface is independent of the applic

Problem:
If we want to write a builder class, we can write as follows:
Class Person
{
Public:
Void BuildHead ();
Void BuildBody ();
Void BuildArmLetf ();
Void BuildArmRight ();
Void BuildLegLeft ();
Void BuildLegRight ();
};
But what should we do when we want to build a thin, fat, and tall person?
Of course, we will think of defining the class of the builder above as an abstract class, and then defining t
Builder Pattern)
Once you hear this name, you may guess one or two points. A builder simply understands that it is something to create. It is just something that the builder model creates, not something that is more complex than a hacker. It is like building a house. You need to build a foundation, build a wall, fill cement, seal the top, and tile the last wall.
1. definition of builders (builder, or generator) mode(1) Separating a complex object construct from its representation so that the same build process can create different representations.① the above mentioned " build " refers to the construction process of the algorithm (that is, the construction sequence, in the Director class), " representation " refers to the specific details of the generated parts (or called implementation, In the
Builder Builder Mode (Create-mode)The origin of builder modeSuppose you create a house facility in the game, the building is made up of several parts, and the parts are richly varied.If you use the most intuitive design method, the changes in each part of the House will lead to the re-revision of the building.Motive (motivation)In the software system, sometimes f
However, you must have a UML to make it clear. Generally, I only remember UML diagrams. Some patterns have their own fixed implementations.Code(Only part of this interface), especially in C #, the user is even treated as a client without exposing its internal implementation. Only encapsulated mode interfaces are published. So I will record some fixed implementation methods. There are also applicable scenarios (see more examples), advantages and disadvantages. Finally, the comparison between the
Flash Professional cs5 provides the workflow between flash pro and flash Builder 4.
The workflow used by the producer includes:
In flash Builder 4, compile, remove, or issue the program in the Flash pro cs5.
You can use Flash Professional to activate the event 3.0 in Flash Builder 4.

Design Mode (5) creator mode (Builder)I. Schema Definition
Builder Pattern: separates the construction of a complex object from its representation, so that different representations can be created during the same construction process.
The builder mode is used to create a complex object step by step. It allows users to build complex objects by specifying the types
