About Visual Basic Language: –

Visual Basic was developed forms the BASIC programming language. In 1970’s Microsoft got its start by developing ROM based interpreted Basic for the early microprocessor based computer. In 1982, Microsoft QuickBasic revolutionized Basic and legitimized as a serious development language for MS-DOS environment. Later on, Microsoft Corporation created the enhanced version of BASIC called Visual Basic for Windows.

Visual Basic 6.0 allows creating Object Oriented Application. When Visual Basic originally developed, it allowed to the programmer to create programs using pre-defined objects, forms and controls. It uses some of the Windows 95 Controls. Visual Basic 6.0 can be used to develop both standalone systems and Client Server Based systems.

Visual Basic 6.0 comes in three categories

• Standard Edition
• Professional Edition
• Enterprise Edition

Visual Basic 6.0 profoundly concentrates on the Internet development features, ActiveX technology, enhanced controls, enhanced features of existing control, client/server, new language features development, data access, a few design enhancement etc.,

Native Code: –

A Visual Basic project is compiled to native code for faster execution. Profiles native code using new native code compiler option, and debug native code using the Visual C++ environment.

Features of existing controls can be combined, or new control can be created form the scratch. ActiveX controls created with Visual Basic have events, data binding

Support, licensing support, property pages, Internet features, and more.

The application Wizard is new and the Setup Wizard has been enhanced to enable creating a dependency file for a standard project. In the professional Edition, the ActiveX control Interface Wizard, ActiveX Document Migration Wizard, Data Form Wizard, and property page Wizard is new. The Setup Wizard has been enhanced to support distribution via the Internet. The installation of remote server components using Distributed COM (DCOM) and Remote Automation is an added feature. The ability to create dependency files for projects and components created with Visual Basic.

The new model allows to programmatically extending the development environment and control projects, events, code, and Visual elements.

Objects provided by the components can raise events that can be handled in other applications, or by our objects, using withEvents variables, Events provide a simple alternative to asynchronous callbacks.

DLL components marked for unattended execution can be used efficiently by multithreading applications such as Internet Browser.

This control provides HTTP and FTP support.

Multiple projects can be opened in the same instance of Visual Basic, with is useful for debugging ActiveX controls.

Create Active X Document: –

ActiveX document s can be created that boosts the Visual Basic application to the Internet Browser Windows. The data control, DAO or Microsoft Access, you can create that is virtually database independent, because jet automatically performs all syntax and data manipulation translations.

This feature allows us to access ODBC data sources throughout the RDO with DAO objects, by passing the Microsoft Jet Database Engine. We can also use ODBC Direct through the data Control, by binding controls to data and setting and ODBC Direct property.

Project, properties, Debugging, and Object Browser windows can be docked in the development environment and/or linked to each other. Toolbars can be docked, undocked, or linked to each other.

A technology that enables application to provide objects in a consistent way to other application, development tools and macro languages. Formerly known as OLE Automation.

Class: –

Class is the formal definition of an object. The class acts as template which an instance of an object is created at run time. The class defines the properties of the object and the methods used to control the object’s behavior. Class’s uses can typically be categorized as one of three general types. They are

• Creation of Business Objects

Ex: Employee object

• Encapsulation of programming functions

Ex: Encapsulate the code that opens a record set in a class module

Ex: Program Wizard

Polymorphism relates to the use of the same method name in various objects; for example, a print method for the printer, a form, or a picture box. While the name of the method is the same, the actual code for the method in each object can be different. However, because the code for the method is encapsulated in the object, each object knows how to perform the correct task when the method is called, this feature allows classes to support multiple interfaces. Users of components can early bind to these interfaces, regardless of the object that implements them.

The data about an object and the code used to manipulate the data are contained within the object itself. The data is stored as the properties of the object and the code as the methods of the object. This feature allows the object data and code to stand alone, independent of outside routines.

The Component Object Model (COM) is a specification. It specifies how to build components that can be dynamically interchanged. Com provides the standard that component and clients follow to ensure that can operate together. COM is Microsoft’s top-level, all encompassing binary and wire specification for the interoperation of one app with another, across multiple applications, machines, and hardware types. It provides the following features.

• Single programming model
• Binary compatibility
• Uniform data transfer
• Structured storage
• Component software, reusable functionality
• Macro programmability
• Programming language independent
• Distributed operation

• Binary Compatibility and Cross-platform Development
• Code Reusability
• Version Control

The first major advantage of component technology binary compatibility and cross-platforms. Since becoming an Industry-wide standard, COM-compliant client applications and servers are independent of the development language and operating system.

The second major advantage of component technology is an enhancement of DLL technology. COM components expose groups of methods, known as interfaces, through which clients interact with objects. Because these interfaces are documented, many clients for a variety of different purposes can reuse the code that creates those objects.

The last major advantage resolves issues related to version control. COM components are said to be self-versioning. This means that new functionality can be added to a component without affecting clients that already use the components. Functionality is not lost when components are upgraded it is always enhanced or added.

MS-ACCESS:

When we create a Microsoft Access database, we create one file that contains the data and table structures as well as the queries, forms, reports and other objects that make up the database.

Protecting information can be an important part of developing a Microsoft Access database. By securing your database, you can control what a user, is a group of users, can do with database objects. Microsoft Access security made up of several pieces that must be in place before security is complete. Security relies on a relationship between Microsoft Access stores account information with the work group and permissions assignment in the database (.mdb) file Microsoft Access Version 7 system database includes several internal security enhancements.

Encrypting a database makes it indecipherable by a utility program or word processor. Encrypting a database compacts the database file and makes it indecipherable by a utility program or word processor. Decrypting a database reverses it indecipherable in order to protect it from unauthorized viewing or use.
