But Sun Microsystem came up with a fantastic language called Java. This language was becoming too famous and popular since its birth and by 90's its JAVA, JAVA and only JAVA everywhere. Microsoft who was struggling with the PC market at that time want's to capture the opportunity and Microsoft was building everything like the OS  and Office and Java was taking the credit of so called windows application so then MICROSOFT plans to launch its own language.

An application that provides sending fax from faxmodem, connected to the computer, will be explained in the following post.  We can use Telephony Application Programming Interface (TAPI) and the Fax Service Extended Component Object Model (COM) API to send fax. The fax service is a Telephony Application Programming Interface (TAPI)-compliant system service that allows users on a network to send and receive faxes from their desktop applications. The service is available on computers that are running Windows 2000 and later. The fax service provides the following features: Transmitting faxes Receiving faxes Flexible routing of inbound faxes Outbound routing Outgoing fax priorities Archiving sent and received faxes Server and device configuration management Client use of server devices for sending and receiving faxes Event logging Activity logging Delivery receipts Security permissions The following Microsoft Visual Basic code example sends a fax. Note that...

What is OOP? Object oriented programming is a type of programming paradigm based around programming classes and instances of classes called objects. These can be objects that appear on the screen (e.g., pictures, textboxes, etc.) or are part of the programming (e.g. actors, connections, particles, etc.) What is an Object? An object is merely a collection of related information and functionality. An object can be something that has a corresponding real-world manifestation (such as an employee object), something that has some virtual meaning (such as a window on the screen), or just some convenient abstraction within a program (a list of work to be done, for example). An object is composed of the data that describes the object and the operations that can be performed on the object. Information stored in an employee object, for example, might be various identification information (name, address), work information (job title, salary), and so on. The operations performed might include...

Three Tier Architecture: Very Easy to understand, the three tier are: 1. Presentation layer 2. Business Layer 3. Database Layer Simple Example: Lets take example of a Songs and Artist. 1. DataAccess Layer Below is a class of Data Access Layer, that has some dummy/fudge data, we only write DataBase calling method in DataAccessLayer. using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace DataBaseLayer {     public class DataAccessLayer     {         string [] ArtistName = { "Akon" , "Shakira" , "Michael_Jackson" };         string [] Shakira = { "Waka Waka" , "Addicted to you" , "Beautiful Liar" };         string [] Akon = { "Chammak Challo" , "Lonely" , "Dont Matter" };         string [] Michael_Jackson = { "Beat It" , "Danger...

Create Statement The CREATE statement is used to create a new table with no record. Let's create the table office . The records in the office table will contain a technical id, the name of the office, a description, the number of available places, the availability and the date for the next office security control: Query : CREATE TABLE office ( id_office INTEGER PRIMARY KEY NOT NULL , name VARCHAR ( 20 ) NOT NULL , description VARCHAR ( 255 ) , place_number INTEGER NOT NULL , available SMALLINT NOT NULL DEFAULT 1 , next_inspection DATE NOT NULL ) ; The table after the statement : office id_office INTEGER name VARCHAR(20) description VARCHAR(255) place_number INTEGER available SMALLINT next_inspection DATE  ALTER statement  The ALTER statement is used to modify a table. It can be used on a table with records in it.
