Introduction to the Lazarus IDE - visual progr. environment

After watching the video and reading the PDF file, students will understand what types of forms there are in Lazarus IDE and how to work with them.

I had originally divided the video into four parts, but here I saw that only one video could be uploaded, so I had to either merge my four video files into one - which is not a good idea!

The other option was to make four separate lectures, which is also not a very good idea!

And so I settled on the option of making 3 lectures on this topic, and in the second part I merged the videos from lessons 1 and 2 into one file.

The video files are as follows Forms in Lazarus IDE:

1. Part I - In the first part I show the most important properties of forms in Lazarus IDE.

2. Part II - Lesson 1 - Theoretical part + Lesson 2 - Practical part - in them I show theoretically and practically a real program made with Lazarus IDE.

3. Part III - In the third part I explain about the types of forms and the transparency property of the form in Lazarus IDE. Here we also have a practical project - to point 5 in the PDF file of this lecture.

   
   

I will not give separate exercises here - it is enough to read the material carefully and do everything described in the lesson yourself!

Here I have combined two video lessons into one lecture, because they are for the same part. In lesson 1 we talk more about the theoretical part, and lesson two is more of a practical part. In these lessons I show theoretically and practically a real program made with Lazarus IDE.

Here I will not give separate exercises either - it is enough to read the material carefully and do everything described in the lesson yourself!

This is an introductory lecture that briefly explains which databases can be worked with in Lazarus IDE, with an emphasis on free databases. It also covers the main components for working with databases in Lazarus IDE.

The material is entirely theoretical.

This is a lecture explaining which components are needed and used when working with the free (embedded) SQLite DBMS in Lazarus IDE.

The material is entirely theoretical.

In this lecture and in this tutorial we will look at Example 1 of working with the SQLite DBMS in Lazarus IDE - When we create an empty database ourselves.

This is an almost entirely practical example and lesson.

Here I will not give separate exercises either - it is enough to read the material carefully and do everything described in the lesson yourself! (If you have a lot of difficulty - you can look at the solution in the finished example.)

In this lecture and in this tutorial we will look at Example 2 of working with the SQLite DBMS in Lazarus IDE - When  we will create a pre-empty DB with SQLliteStudio.

In this lesson we do not have a practical example applied because we are working with an external program.

Here I will not give separate exercises either - it is enough to read the material carefully and do everything described in the lesson yourself! (If you have a lot of difficulty - you can look at the solution in the finished example.)

In this lecture and in this tutorial we will look at Example 3 of working with the SQLite DBMS in Lazarus IDE - When we will pre-create a database with records.

This is an almost entirely practical example and lesson.

Here I will not give separate exercises either - it is enough to read the material carefully and do everything described in the lesson yourself! (If you have a lot of difficulty - you can look at the solution in the finished example.)

In this lecture and in this tutorial we will look at Example 4 of working with the SQLite DBMS in Lazarus IDE - When we will find out which database we are currently working with.

This is an almost entirely practical example and lesson.

Here I will not give separate exercises either - it is enough to read the material carefully and do everything described in the lesson yourself! (If you have a lot of difficulty - you can look at the solution in the finished example.)

In this lecture and in this tutorial we will look at Example 5 for working with SQLite DBMS in Lazarus IDE – When we will use the universal component for working with databases - TDBNavigator!

This is an almost entirely practical example and lesson.

Here I will not give separate exercises either - it is enough to read the material carefully and do everything described in the lesson yourself! (If you have a lot of difficulty - you can look at the solution in the finished example.)

In this lecture and in this lesson we will look at Example 6 for working with SQLite DBMS in Lazarus IDE – When we will make a simple program we will use the universal component for working with databases - TDBf together with this component from the previous lesson - TDBNavigator!

This is an almost entirely practical example and lesson.

Here I will not give separate exercises either - it is enough to read the material carefully and do everything described in the lesson yourself! (If you have a lot of difficulty - you can look at the solution in the finished example.)

In this lecture and in this lesson we will look at Example 7 for working with SQLite DBMS in Lazarus IDE – In this example, we will remove the TDBNavigator and use buttons, text and other fields, and another form instead. By placing four more buttons on our form with titles: Add, Delete, Edit, and Refresh. And we will enter data and work with it through these buttons.

This is an almost entirely practical example and lesson.

Here I will not give separate exercises either - it is enough to read the material carefully and do everything described in the lesson yourself! (If you have a lot of difficulty - you can look at the solution in the finished example.)

In this lecture and in this lesson we will look at Example 7 for working with SQLite DBMS in Lazarus IDE – In this example, we will convert the previous example to a Telephone directory program, using almost the same buttons, text fields, and other fields, with some modifications and replacements. We will use the Add, Delete, Edit, and Refresh buttons. And we will enter data and work with it using these buttons and another form.

This is an almost entirely practical example and lesson.

Here I will not give separate exercises either - it is enough to read the material carefully and do everything described in the lesson yourself! (If you have a lot of difficulty - you can look at the solution in the finished example.)

This topic Example 9 for the real and complex program Library with SQLite DBMS in Lazarus IDE – I have divided it into two lectures and two lessons respectively.

In this lecture you will see how we will create such a program by converting the previous example of a phone book, into a Library by working with a menu. We will use buttons only in the additional forms through which we will enter the data.

Here I will not give separate exercises either - it is enough to read the material carefully and do everything described in the lesson yourself! (If you have a lot of difficulty - you can look at the solution in the finished example.)

This topic Example 9 for the real and complex program Library with SQLite DBMS in Lazarus IDE – I have divided it into two lectures and two lessons respectively.

Here I will not give separate exercises either - it is enough to read the material carefully and do everything described in the lesson yourself! (If you have a lot of difficulty - you can look at the solution in the finished example.)

In this lecture we will look at the same program from Example 9 for the real and complex program library with SQLite DBMS in Lazarus IDE .

But here you will see how we will create such a program for the MySQL server database, by adapting and converting the previous Example 9 into the program library with SQLite.

For the example to work for you - you need to install the MySQL database and create the tables in it. This is explained how to do it in the PDF file attached to the lecture here.

Here I will not give separate exercises either - it is enough to read the material carefully and do everything described in the lesson yourself! (If you have a lot of difficulty - you can look at the solution in the finished example.)

That was all, dear students and trainees. I sincerely hope that this course of mine, based on my book of the same name Introduction to Lazarus IDE, was useful to you and that I managed to teach and introduce you to the basic principles of working with Lazarus IDE! And that, if not completely, then at least partially, you have already mastered these principles.

Of course, you should also keep in mind that this course is just the beginning for you. If you really want to advance in this area yourself, you will have to read and experiment a lot more. In addition, you will have to learn new things. Because the course is only an introduction and far from covering all the possibilities that you are likely to use at a later stage of your work. And its goal is to give you the foundation, and to teach you, and to put in you a good start for work. And then you will be able to build on it much easier.

I can also say that this will not be all from me (life and health be with you). I plan to upload another course here - on Creating a Website from Scratch, based on my other book. I also intend to work and continue to develop these topics with new lessons, courses, books.

For news and other questions about the book, you can write to me on my website, where there is also an electronic version of the book, as well as articles about Lazarus IDE, HTML, CSS, and many other interesting things.

Best regards!
