Hello C++ Developers,
We have new C++ posts with examples that can be used in your Windows applications. These examples are specifically for C++ Builder. The same commands exist for the Delphi programming language. While the examples are focused on Windows applications, some of these examples can be used in your Mobile application. These can be used in modern applications and help to extend your C++ knowledge. You can also use them in your console VCL or FMX applications.
C++ Builder has a lot of specific methods in its SysUtils library that are included in VCL and FMX libraries. Some of these are grouped together as Path Manipulation Routines that allow users to edit, extract, get and set drive name, directory name, file name, and file extensions. These methods are combined in Vcl.FileCtrl, System.IOUtils, System.SysUtils libraries. They’re all easy to use and make it simple to get or set file path strings from Windows. These can be used with other component properties like the FileName property of OpenDialog, SaveDialog components. We can also check drives, files, or directories to see if they exist or not on a given path. We can include and exclude path delimiters on Windows, we can create random file names GUID file names. We can include and exclude path delimiter characters safely from the path strings.
There is an OnIdle method to define the idle loop of the application. ProcessMessages and HandleMessage methods are useful to process and handle messages of the application.

Here are our favorite educational C++ posts of this week
These are the posts below that you can find all the answers of the listed questions,
We keep adding new topics about C++ in general and specific topics for C++ Builder, Dev-C++, and for the other C++ compilers. Please keep following our LearnCPlusPlus.org website which focuses entirely on educating C++ developers – whether they are just starting out or wish to learn some skills. Feel free to comment and share with your colleagues, students, members – C++ is great all-purpose language.
C++ Builder is the easiest and fastest C and C++ IDE for building simple or professional applications on the Windows, MacOS, iOS & Android operating systems. It is also easy for beginners to learn with its wide range of samples, tutorials, help files, and LSP support for code. RAD Studio’s C++ Builder version comes with the award-winning VCL framework for high-performance native Windows apps and the powerful FireMonkey (FMX) framework for cross-platform UIs.
There is a free C++ Builder Community Edition for students, beginners, and startups; it can be downloaded from here. For professional developers, there are Professional, Architect, or Enterprise versions of C++ Builder and there is a trial version you can download from here.
