1_Algorithm Example Edition
no vote
A few of well known algorithms are implmented here. A procedure (call) consists of the name of a procedure (with or without qualifiers), followed by a parameter list (if required). Functions return a value where procedures must not! Most functions and procedures require parameters of specific types. As we already know a type is just a name for a kind of data and parameters must have the types of a language or self defined ones. To make a computer do anything, you have to write a computer program . To write a computer program, you have to tell the computer, step by step, exactly what you want it to do. The computer then "executes" the program, following each step mechanically, to accomplish the end goal.

2_Graphics Example Edition
no vote
Here we show some graphic examples with objects: A Class is a blueprint or prototype from which individual objects are created (later on we create an object). Methods appear in a class declaration as function or procedure headings, with no body. Defining declarations for each method occur elsewhere in the program.

3_Games Example Edition
no vote
We found several game concepts in the way of script: there are 7 examples of this. The tutorial will introduce you to a simple game called arcade like famous bang. The first popular "arcade game" is the early game midway in amusement park, such as shooting range, ball tossing game, the earliest coin machine, such as those claiming to tell a person a person's fortune or playing music. Today's games have become so complex that they require a lot of developers, graphic artists, testers and overhead to develop. In addition, the improvement of multi-user function. In terms of their complexity and cost millions of euros, their competitors develop and sell large commercial enterprise applications. So the rest of this embodiment provides technical details about the game in a common way in development.

4_Multimedia Example Edition
no vote
We show some multimedia concepts like mp3 or video player: Today we spend time in programming forms on an application. TApplication, TScreen, and TForm are the classes that form (yes I mean form) the backbone of your applications by controlling the behaviour of a project. The TApplication class forms the foundation of an application by providing properties and methods that encapsulate the behaviour of a standard script or program. TScreen is used at runtime to keep track of forms and data modules that have been loaded as well as maintaining system-specific information such as screen resolution, cursors and available display fonts. Instances (objects) of the TForm class are the building blocks of your application's graphical user interface (GUI).

5_Internet Example Edition
no vote
We show you the basic concepts of Internet and HTTP / HTML: this example and tutor 5 lessons will introduce you to Internet and print socket and Library in a separate way. So, what is print socket and telnetcpsocketserver TTSS? Indy.Sockets VCL supports client, server, TCP, UDP, raw socket, and more than 100 higher level protocols, such as SMTP, POP3, FTP, HTTP and an open source socket library. Indy.Sockets Written in Delphi, but can be used for C, C + +, Delphi any. Net language, and Kylix (CLX). In our example, we show two examples of HTTP (and the third one in our own service). Let's start with HTTP and TCP. TCP / IP stands for transmission control protocol and internet protocol. TCP / IP protocol can mean many things, but in most cases, it refers to the network protocol itself.

6_Communication Edition
no vote
Serial communication is based on a protocol and the standard RS 232. A protocol is one or a few sets of hardware and software rules agreed to by all communication parties for exchanging data correctly and efficiently. RS-232C, EIA RS-232, or simply RS-232, refers to the same standard defined by the Electronic Industries Association in 1969 for serial communication. We will concentrate on creating a serial call of a component using a class TSerial from a component which calls the winapi dll library. But, first of all I'll explain you what "blocking clock" and "nonblocking signal" calls are. In fact there are 2 programming models used in communication driven applications:

7_Geographical Example Edition
no vote
Today we run through GEO Maps coding. To find a street nowadays is easy; open a browser and search for. One of the questions that comes up when encoding those coordinates is how they can be useful in a script with for example in maXbox: OpenMapX('cathedral cologne'); OpenMapX('50.94134 6.95813'); //string! With a GPS or navigation: The Global Positioning System (GPS) is a spacebased satellite navigation system that provides location and time information in all weather conditions. But you need a map to visualize.

8_Operating Example Edition
no vote
Today we spend another time in programming with your operating system (called OS) and the API. An API (Application Programming Interface) is the port to the library of your system. Most of the VCL is designed for working with the Windows API or the CLib of Linux. This is handled in a way analogous to the way a call to a DLL (dynamic link librarie) works: The VCL1 is a managed API that calls into the Win API, marshalling between the managed structures on the VCL side and the unmanaged types and operations that the Win API uses.

9_Database Example Edition
no vote
This lesson will introduce you to SQL (Structured Query Language) and a database connection. The term "inquiry" refers to searching, questioning, or finding or researching. When you query a database, you are searching for information in the database. The query component encapsulates an SQL statement that is used in client applications to retrieve, insert, update, and delete data tables from one or more databases. The query component can use a remote database server (client / server) and many other database drivers. Most of the time, you use queries to select the data a user should see in the application, when you use the table component, just as you do. Query, however, you can also update, insert and delete display operations and retrieved records. When you use queries to perform insert, update, and delete operations, queries usually do not return records for viewing.

10_Science Example Edition
no vote
We show some topics in research and development: A parameter is a numeric measurement that describes some property of the population for example mean or max height of a random sample from a population. In this large field we deal with some basics today called probability. Probability is the study of chance or the likelihood of an event happening. Directly or indirectly, probability plays a role in all activities. For example, we may say that it will probably possible to unlock the lock because most of the combinations are too easy. Zufall ist nur der Ausdruck unserer Unfaehigkeit, den Dingen auf den Grund zu kommen A. Einstein (Ein grosser Skeptiker in Sachen Zufall) Random numbers should not be generated with a method chosen at random Donald E. Knuth
