Delphi examples for Windows 7. Review of the free version of Delphi. Installing the help system
It is one of the most successful products in the line of integrated processing environments from Borland (started with the Borland Delphi product and the latest at the moment 10.1 Berlin). The program is intended primarily for developing applications in a client-server architecture. The main modules produced by Delphi 7 are .exe and .dll. The visual design environment of the program takes on many routine functions for preparing the application. This speeds up the application creation time and improves its quality. The Borland C++ Builder product has many similar parameters, but instead of Pascal it uses the C++ language.
Advantages and Disadvantages of Delphi
Application development time is significantly lower than when working in similar programs;
+ high productivity in a compact volume;
+ the created application has minimal requirements for PC resources;
+ the ability to expand the program’s potential through built-in modules;
+ as well as the ability to create such modules in the Delphi environment itself;
+ harmonious hierarchy of objects;
- large size of some final applications and programs;
- inability to use other standard UI;
- lack of flexibility and originality: any program made in Delphi can be understood to be made in Delphi.
Key Features
- creation of applications and application programs in Delphi language;
- launching and debugging programs in Delphi;
- creation of cross-platform Rave Reports;
- work in the ModelMaker modeling environment;
- WEB application development;
- editing, debugging and launching WEB applications;
- visualization, integration and reengineering;
- built-in manuals for basic functions;
- the ability to use ready-made design templates;
- using .exe and .dll modules.
So now you have a problem if you write a library that will be used by both old-school code written with wchar_t defined as an alias for unsigned short and new-school code written with wchar_t as a separate internal type. What data type do you need to use for string parameters?
This is a translation of The sad history of Unicode printf-style format specifiers in Visual C++.
Windows implemented Unicode earlier than most other operating systems. As a result, Windows solutions to many problems differ from those made by those who waited until the dust settled¹. The most prominent example of this is Windows' use of UCS-2 as its Unicode encoding. It was then the encoding recommended by the Unicode Consortium because Unicode 1.0 only supported 65"536 characters². The Unicode Consortium changed its mind five years later, but by then it was too late for Windows, which had already released Win32s, Windows NT 3.1, Windows NT 3.5 , Windows NT 3.51 and Windows 95 - all of which used UCS-2³.
But today we'll talk about printf style format strings.
This is the translation of If FlushInstructionCache doesn’t do anything, why do you have to call it, revisited .
You are expected to call the FlushInstructionCache function when you generate or modify executable code at run-time - so that the processor, when executing your generated/modified code, reads the instructions you wrote, rather than old instructions that may remain in the processor's instruction cache.
Previously we learned that . This is because a simple function call was enough to clear the command cache.
But in Windows NT, the FlushInstructionCache function does the real work because it needs to notify all other processors to flush their caches.
However, if you look at Windows 10, you will find that the FlushInstructionCache function looks like the Windows 95 version: she doesn't do anything.
What's the matter?
Today I decided to add another section to the blog, called “Programming”. It’s just that sometimes you have to delve into this area, figure it out, study and program at least a little. And sometimes information appears that needs to be saved in order to be quickly found when needed. In this section I will write about different programming languages, but mainly, I think, the Delphi language will be used. Why? I just like him!
The first article will discuss the question of how to install a component on Delphi 7. Read on!
Sometimes a situation arises when there are not enough standard components of the environment, despite the fact that there are a huge number of them, to implement certain functions of the program you are writing and therefore you have to install add-ons (components) or write them yourself. But why reinvent the wheel, because there are already ready-made solutions. However, I didn’t immediately find any instructions for installing components on Delphi 7 (Delphi 7). There were only fragments of proposals and assumptions. Therefore, I decided to write everything down point by point, for myself and for you.
Installing the component on Delphi 7 step by step:
1. Launch Delphi 7.
2. In the menu, select “Component”, then “Install Component...”. The window shown in the figure below will open.
3. In the window that opens, opposite the “Unit file name:” field, click on the “Browse...” button and specify the path to the *.pas file of the component, click “Open”, and “OK” in the initial window.
A window with approximately the following content should open (picture below).
Click the “Yes” button to compile. After compilation, the window can be closed.
Congratulations, the component is installed!
All that remains is to register it and indicate the location, and this is done as follows:
4. Go to the menu, select “Tools” and select “Environment Options...”. In the window that opens, go to the “Library” tab; the window view is shown in the picture below.
5. Click on the “…” button opposite the first line where it says: “Library path:”, a window will open, the view of which is presented below.
6. In the window that opens, click on the “…” button, it’s the only one there, it can’t be confused with anything :). In the window that appears, select the folder in which the component is located and click “OK”. Then click the “Add” button, which has become active. Close open windows using the “OK” button.
Ready! The installation process of the component on Delphi 7 is complete! You can use it to the fullest!
Good luck with the installation! If you have any questions, write, I will try to answer them!
For those who have always dreamed of creating their own program, we recommend learning the C++ language. To program you need not only knowledge, but also a programming environment. You can download Delphi 7 for Windows 10. Delphi 7 is one of the most popular utilities for Windows, with which you can create your own application of any complexity. The seventh version of Delphi is the most popular, as there are thousands of manuals and instructions for it, as well as Delphi 7 in Russian, which is especially important for beginners.
Delphi 7 is the ideal programming environment for Windows 10
You can not only download programs, but also create your own. Of course, without knowledge of programming this will not work, but you can download Delphi 7 and start learning based on this software editor. Code in Delphi 7 is highlighted, which is very convenient. There is also a huge knowledge base that is at your complete disposal. This knowledge base is a great help for those just starting out in programming. Pros of the latest version of Delphi 7:- Software environment for developing applications of any complexity;
- Java support;
To deploy the development environment, the above programs are sufficient. Delphi 7 runs on Windows 10 32 bit and 64 bit. Development can be carried out either on a classic computer or on a laptop or tablet. The program is completely undemanding to your device. You will be able to compile various programs without overloading your device. This is another plus of the latest version of Delphi for Windows 10.
Delphi 7 is a free development environment. You can download Delphi 7 for free and also find thousands of instructions on how to program for free. The program itself contains only a brief reference on programming; it will definitely not be enough if you do not have the knowledge. But those who are just starting out will benefit from both code highlighting and a large selection of ready-made libraries that can be used in developing their own applications. This is a serious product, so don't be surprised by the size of the installation file that is distributed via
