In the Object Oriented terminology, we will talk about abstraction and encapsulation in the context of Visual Basic. The concepts may be useful to many coders, but I have presented the content with beginners in mind. We start with creating a class in Visual Studio and then write some code while discussing various concepts like classes and objects, access types (public, private and friend), properties (and paramterized properties), methods, events, instantiation, enumerations and so on.

Probably, you simply replace the battery with a new one. Is it? Now, what do you think, you know everything about the battery and the torch? I mean their architecture, functionality, etc.? If, by any chance, you know then does everybody who replaces the battery know about the details of the battery and the device? Obviously not.

We may say that ‘Active-X’ means ‘COM enabled software components’. So, Active-X Data Objects are the components based on COM specification, meant for providing Data Access Capabilities to the client.

Microsoft has developed ADO so that the client languages which cannot call low level API’s, such as OLEDB, can use them for database operations. So ADO is a component that encapsulates OLEDB API. As this component is based on COM, VB, VC++, Scripting Languages, etc. can [...]]]> http://coder000.com/com-in-visual-basic-with-ado-an-introduction/feed/ 2
