Windows Printing with C++Builder using VCL and FMX

Do you need to add printer support to your C++ applications using the Visual Component Library (VCL) or FireMonkey (FMX) GUI ? In this blog post I'll show you how to build Windows applications that support printing image bitmaps using the VCL and FMX frameworks. One of my favorite C++Builder RTL features is that both … Continue reading Windows Printing with C++Builder using VCL and FMX

Using the Eigen C++ Template Library with C++Builder and VCL

It's been almost 50 years since I took a Linear Algebra and Matrices course as one of my Computer Science electives at Cal Poly San Luis Obispo, CA. The textbook for the course was "Mathematics Of Matrices: First Book Of Matrix Theory And Linear Algebra" by Philip J Davis. While I have used arrays and … Continue reading Using the Eigen C++ Template Library with C++Builder and VCL

Two VCL Example Applications that Use C++Builder and the C++ Boost Libraries

Boost is a set of open source C++ libraries that build on the ISO C++ programming language. In some cases, the Boost library functionality has become part of recent ISO C++ standards. RAD Studio allows you to install a subset of Boost that has been fully tested and preconfigured specifically for C++Builder. Use the GetIt … Continue reading Two VCL Example Applications that Use C++Builder and the C++ Boost Libraries

Building a C++Builder RSS Feeds VCL Application with XMLDocument, NetHTTPClient, NetHTTPRequest and WebBrowser Components

I have many favorite prebuilt components that are included with C++Builder 10.4 Sydney. In this blog post I'll show you how to create an RSS Feeds VCL (you can also use the same approach for a FireMonkey FMX) application using the XMLDocument, NetHTTPClient, NetHTTPRequest and WebBrowser components. Start by creating a C++Builder VCL application. Set … Continue reading Building a C++Builder RSS Feeds VCL Application with XMLDocument, NetHTTPClient, NetHTTPRequest and WebBrowser Components

Using C++Builder to list all available VCL styles in a ComboBox and apply a selected style using the ComboBoxChange event

Back in June a developer asked a C++Builder question on StackOverflow. The question was "How can I list all the available VCL styles in a combo box and in the ComboBoxChange event, apply that style in C++ Builder?" I answered the question and gave the example code. One of my favorite RTL features for the … Continue reading Using C++Builder to list all available VCL styles in a ComboBox and apply a selected style using the ComboBoxChange event

Multithreaded Sorting with C++Builder and the Parallel Programming Library (PPL)

The Parallel Programming Library (PPL) is one of my favorite features in C++Builder runtime library. PPL allows developers to create tasks that run in parallel to take advantage of multi-core processors. Using the PPL, you can: 1) speed up loops with a Parallel For, 2) run multiple tasks in parallel using TTask, and 3) use … Continue reading Multithreaded Sorting with C++Builder and the Parallel Programming Library (PPL)
