In C++ Builder, it is easy to draw images on Bitmaps by using Canvas property and methods to draw, Canvas can be used on both VCL and FMX applications. Canvas provides an abstract drawing space for objects that must render their own images. TCanvas provides properties, events, and methods that assist in creating an image by:
Specifying the type of brush, stroke, and font to use.Drawing and…

This post about listing String and displaying methods as fast as possible in Modern C++, in C++ Builder FireMonkey projects. In general if you have many String additions to you component, you must use BeginUpdate() and EndUpdate() methods of that Class member to do these…
The source code written in C++ must be compiled (i.e. translated to the machine code) by one or another compiler such as Embarcadero RAD Studio C++ compilers before in can be runned. In general, there are two types of the resulting machine code: library and main executable (hereinafter simply executable). This post will briefly cover the later of these two.
When an executable produced from a…
The posts General Loop Statements in Modern C++ and Range-for-statement in modern C++ cover ways to write explicit loops. But explicit loops can be tedious to write and, what is more important, – harder to read, because the resulting code requires to spend the extra…
This article is about to help you on implementing an Artificial Neural Network by using FANN Library developed by Steffen Nissen. It supportsmore than 20+ programming languages (http://leenissen.dk/fann/wp/language-bindings/) including Delphi and C++ Builder. You can…
Each loop statement in C++ has its loop body which is executed repeatedly until the loop condition expression that yields a loop condition becomes false (otherwise, the loop will run “forever”). The statement continue can be used to interrupt the current iteration and skip the rest of the loop body to immediately check the loop condition before continuing. A whole loop statement can be…
The C++ language provides the switch statement which can be used to replace the set of if statements (see If Statements in Modern C++). First of all, let’s define the enum type Traffic_light_color as follows:
enum class Traffic_light_color { red, yellow, green…
Delimiters (token term also used) are characters which separates strings between each of them. For example spaces, comas and other symbols can be used as a delimiter char to separate strings between them . Normaly in C++ strtok() were being used in C++, that is used with…
Bitmap is a standard for reading and writing pixels of images of applications on all platforms (Windows, MacOS, iOS, Android, Linux, …). A Bitmap includes bitmap information and full uncompressed image in pixels. Each pixel of this uncompressed image consists 4 color members called ARGB (Alpha Red Green Blue) and it can be set or shown as 0xAABBCCDD in hexadecimal format.
