delphi courses. Learning the basics of programming in Delphi courses. What version of Delphi to install
Modern world programming does not stand still, or rather, he walks by leaps and bounds. Languages develop and improve, acquiring new features that seemed like science fiction in the past. But despite this, the principles remain the same. One of the most popular programming languages, Delphi, is a completely new stage in the life of another language, Pascal. And if the latter language works exclusively with MS-DOS, then Delphi is already designed for visual writing programs for the multitasking Windows system.
Delphi does not contain any abstruse constructions, too complex character sets. Even simpler options for learning programming with a simplified system are Pascal and BASIC. These two languages are kind of "progenitors" of modern programming languages. With their help, it is much easier to master the principles of writing programs. Delphi is already a more complicated version, which is still relevant today for many specialists. From students to system administrators, Delphi comes in handy in many situations.
Delphi allows you to write scripts for the Windows operating system, and with the addition of certain extensions, it is possible to create programs for Linux. The ability to install additional modules, the ease of customizing the interface to individual requirements, the simplicity of programming principles - all this makes the Delphi language popular and relevant today.
The tutor will teach Delphi quickly and efficiently
Delphi courses from the training center "PC Lesson" will allow you to study as efficiently as possible without spending too much time and effort! Our company works on the principle of individual selection of the program and the pace of training. When drawing up a lesson plan, we always take into account the client's ability to devote time to studying, initial training, which may not be at all, wishes regarding the timing of graduation.
To learn Delphi with our programming tutor does not require special training. You may not even be familiar with the basic principles of the Windows operating system - we will teach you how to use the computer and its capabilities from scratch. If you have an initial level in programming, this will greatly facilitate and speed up the task.
Offering our clients a wide range of training courses, we can guarantee an excellent result, your comfort during your studies, high-quality and solid knowledge and effective practice. We are waiting for your calls and are ready to start classes in the near future.
If you are interested in programming in the broadest sense of the word and you set yourself a large-scale task - to learn to program, then the most rational solution for you would be to start with Delphi courses at the Specialist Center.
The Delphi visual programming environment, or RAD (Rapid Application Development) Delphi, was developed on the basis of the Pascal language (Pascal), created specifically for education. This language provides deep detailing and a large "margin of safety" in protection against wrong steps.
On training coursesDelphi students will be able to learn how to develop projects in Delphi that demonstrate various aspects of programming in Delphi. The description of the stages of project development is accompanied by comments, as well as samples common mistakes and shortcomings that may arise in similar situations. Special attention in the process learningDelphi focuses on how to effectively use the main components of the VCL library and how to create a convenient and reliable interface. CoursesDelphi will be useful not only for novice programmers, but also for experienced developers.
In addition, on coursesDelphi the possibilities of the programming system are considered Delphi 2010, the language is described Delphi, the visual components of the system and methods for their creation are considered. Special attention in the process learningDelphi paid to the principles and practices of creating network applications for different architectures, developing programs that support the main protocols of the Internet, tools for organizing the effective work of programmers.

Where to begin?
Delphi, which is based on the Pascal language, is a great place to start learning how to program. Pascal itself is gradually becoming a thing of the past and less and less attention is being paid to it. This is understandable - applications for MS-DOS are written on it, and this single-tasking operating system everyone is trying to forget like a bad dream. To be more precise, the Delphi language is Pascal not in the form in which it is used to write MS-DOS applications, but in another modification - Object Pascal. In this language, programming is, as it were, "attached" to certain objects - both visual and non-visual, just in memory. Programming simple applications with interface command line(i.e. when lines of text are sequentially displayed on the screen and the user enters some data) it is also advised to start with Pascal. Also, many people start with QBasic, but this language is one of the most "ancient" and it has few possibilities. However, it is also suitable for understanding the general principles of programming. The fact is that in these languages there are no ingenious constructions and character sets - the written code is easy to read and understand. This cannot be said, for example, about C++. There are jokes on this topic - "what a programmer wrote in C ++ at night, he will not be able to read in the morning." Of course, this is not true, but the syntax of the C++ language is quite complicated. We will start learning Delphi almost from scratch. Pascal will be studied along the way.
Why Delphi?
Delphi is something different than Pascal, it is a completely different qualitative stage of the programming environment. With the help of Delphi, applications for the Windows operating system are created, but in addition, with the help of additional tools, you can write, for example, programs for Linux. The Delphi environment is easily extended by installing additional modules. The user interface is also highly customizable - everyone organizes their workspace the way they want.
Brief information about Delphi
Delphi is the result of the development of the Turbo Pascal language, which, in turn, developed from the Pascal language. Delphi had a huge impact on the concept of the C# language for the .NET platform. Many of its elements and conceptual solutions have been incorporated into C#. One of the reasons is the transfer of Anders Hejlsberg, one of the leading Delphi developers, from Borland Ltd. at Microsoft Corp.
Version 1 was intended for development under the 16-bit Win16 platform;
Versions from the second compile programs under the 32-bit Win32 platform;
Together with the 6th version of Delphi, the Kylix environment, compatible with it in terms of language and libraries, was released, designed to compile programs for the Linux operating system;
Version 8 is capable of generating bytecode exclusively for the .NET platform. This is the first environment focused on the development of multilingual applications (only for the .NET platform);
Later versions (indicated by release years rather than sequential numbers, as was the case before) can create both Win32 applications and bytecode for the .NET platform;
Delphi for .NET - Delphi development environment, as well as the Delphi (Object Pascal) language, focused on developing applications for .NET.
What do we need...
It is assumed that you are familiar with the general rules of work in Windows system and worked in any applications at least a primitive level like Notepad or Calculator. From software we need the Delphi environment itself. The installation process will not be described, as it is fairly standard. You will not find Delphi distribution kits on the site - any of the versions has a volume of at least 200-300 MB, and storing such files on the site is simply unprofitable. Also, Delphi is not officially free. Therefore, if you do not have a distribution kit yet, try to find it as soon as possible. You can buy it in the store, or take it from someone you know. Of the free analogues of Delphi, Lazarus can be noted, but in these articles we will talk about Delphi.
What version of Delphi should I install?
This is one of the most frequently asked questions. By and large, they are all very similar and in most cases the programs will work the same regardless of the version of Delphi in which they were created. However, I will still give you some advice. Do not install lower versions Delphi 5- they are very old and have significant discrepancies with the newer ones. The Delphi 5 environment contains all the basic features, but it lacks some of the handy things that came in later versions. The best option - Delphi 6 or Delphi 7. These versions are most popular among the "population". Delphi 6 is considered the most stable. Delphi 7 is not much different from Delphi 6, except perhaps for greater compatibility with Windows XP (meaning the compatibility of written applications). This does NOT mean that programs written in Delphi 6 will not work correctly in WinXP. Everything will be great. But Delphi 7 is still less stable than Delphi 6. Further versions - Delphi 8, Delphi 9 I don't recommend installing at all. These are the most unfortunate of all. Attempts were made to integrate tools for writing applications on .NET technologies, but in response, the environments themselves turned out to be rather unsuccessful ("buggy"). Next worth mentioning Delphi 2005 Enterprise Edition. This version also did not receive a particularly wide distribution, and most programmers simply "stepped over" it. Next in line - Borland Developer Studio 2006. Yes, this is already a whole software package, which includes, in addition to Delphi, other development tools. The environment is convenient, but very resource-intensive. On older computers with random access memory less than 1 GB, I do not recommend using it. Borland stopped at this and further production began to be carried out on behalf of codegear(and then - Embarcadero). Delphi 2007 included in RAD Studio 2007, differs little in features from BDS 2006, but it is very well optimized and suitable for use on low-powered machines, unlike its predecessor. Delphi 2009 is a new big step in the development of Delphi. In this version, full Unicode support appeared (everyone was waiting for this and it happened). Of course, along with new spaces for activity, this revealed new problems: some old programs, components and modules stopped working correctly. However, in most cases, all conflicts are resolved by editing a few lines. You shouldn't be afraid of this. If you are just starting your "journey", then there is no difference for you and therefore it is better to install more new version. All examples that will be given in these lessons work correctly in both old and new versions of Delphi. And finally, the latest version - Delphi 2010. I can't say much about her yet. Install it or not - decide for yourself. Perhaps it makes sense to get used to more proven versions for the time being.
Summing up, I advise you to choose from three options: Delphi 7, Delphi 2007 or Delphi 2009. Many people still work on the 7th version, arguing that there is nothing better than it in the world. But it is worth remembering that sooner or later everything old becomes obsolete to such an extent that it becomes unusable. Delphi 2007 is already closer to the present. Well, Delphi 2009 - if you don't want to lag behind the rest of the world. It's up to you, but I would choose the latter option.
