Modernizing Delphi Development with DevExpress VCL 19.1.2 and DxAutoInstaller

If you are a Delphi or C++Builder developer using RAD Studio, you know that keeping your component library up to date is crucial for building modern Windows applications. DevExpress VCL 19.1.2 remains a landmark release for those looking to balance performance with cutting-edge UI features. When paired with DxAutoInstaller 2.2.2, the setup process becomes significantly more efficient. What’s New in DevExpress VCL 19.1.2?

The 19.1 series introduced several transformative features that modernized the look and feel of VCL applications:

Office 2019 Style: The Ribbon Control shipped with a style that replicates the latest Microsoft Office aesthetics, including new tab animations and IDE templates for quick project starts.

Right-to-Left (RTL) Support: Major components, including the Pivot Grid, Vertical Grid, and Wizard Control, received full RTL language support, making it easier to localize apps for global markets.

Excel-Inspired Filtering: New filter dropdowns for the Data Grid, TreeList, and Vertical Grid provide a two-tab interface—one for value selection and another for building complex expressions. DevExpress VCL 19.1.2 Full Source with DxAutoInstaller 2.2.2

Performance Boosts: SVG rendering became twice as fast as previous versions, and the Ribbon/Toolbar UI responsiveness increased by up to three times.

Enhanced Flow Charting: Added 30+ new shapes and support for the layered (Sugiyama) algorithm, which automatically minimizes connector crossings for cleaner diagrams. Why Use DxAutoInstaller 2.2.2?

Installing a full-source version of DevExpress can be time-consuming, as it requires manual compilation and registration of dozens of packages. DxAutoInstaller is a community-favored tool designed to automate this entire workflow.

One-Click Setup: It automatically detects your installed RAD Studio versions (like Delphi 10.3 Rio) and handles the compilation of the full source code into the necessary BPL and DCP files.

Component Selection: Users can choose exactly which libraries to install, reducing IDE clutter. Modernizing Delphi Development with DevExpress VCL 19

Reliability: Version 2.2.2 brought stability improvements for newer Delphi versions and ensured that registry paths were correctly updated to avoid "Package Not Found" errors upon launching the IDE. Installation Quick Guide To set up your environment:

Extract the Source: Place your DevExpress VCL 19.1.2 source files in a permanent directory (e.g., C:\DevExpress).

Run as Admin: Launch DxAutoInstaller.exe with administrator privileges. Configure: Select your Delphi version and the target path.

Install: Click the install button and wait for the "Successful" message. You will then find over 230+ components ready in your Tool Palette.

By leveraging the full source version, you gain the ultimate flexibility to debug or even extend the components to fit your specific enterprise needs. VCL UI Components for Delphi & C++Builder - DevExpress How DxAutoInstaller Works It is a standalone executable

How DxAutoInstaller Works

It is a standalone executable that scans your system for registered Delphi/C++Builder versions (from Delphi 5 up to 10.4 Sydney, depending on version). It then:

  1. Maps the source directory.
  2. Sorts package compilation dependencies (Runtime before Design-time).
  3. Invokes the command-line compiler (DCC32.exe) sequentially.
  4. Adds the source paths to the IDE's global library path.
  5. Installs the design-time packages into the IDE component palette.

Step 1: Extract Source Code

Create a clean folder, e.g., C:\DevExpress\19.1.2\FullSource. Extract all source subfolders (ExpressCore Library, ExpressDataGrid, ExpressLibrary, etc.) into this directory.

Part 2: DxAutoInstaller 2.2.2 – The Silent Deployment Tool

Issue 1: Compilation Error – "F2051 Unit dxCore was compiled with a different version"

Cause: Leftover DCUs from previous DevExpress installations.
Solution: Delete all *.dcu, *.dcp, *.bpl from your DevExpress source folder. Use the "Clean" button in DxAutoInstaller.

Key Considerations

DevExpress VCL 19.1.2 is a legitimate commercial product from Developer Express Inc., offering native Delphi/C++Builder components. The "Full Source" version requires a valid source code license. DxAutoInstaller is a third-party tool (not officially by DevExpress) sometimes used to automate installation of source versions.

⚠️ Important note: I cannot promote or facilitate software piracy. If you already own a valid source code license for DevExpress VCL 19.1.2, here are legitimate features you could document:

7.3 Moving to a Newer Version

If your budget allows, consider upgrading to DevExpress VCL 23.2 or 24.1. New features include:

  • Direct2D rendering for high-performance grids.
  • Vector skins (SVG-based).
  • Windows 11 context menus and rounded corners.
  • Better high-DPI per-monitor support.

However, be prepared for breaking changes that require code migration.

Phase 1: Preparation

  1. Extract the source: Do not extract to C:\Program Files (Windows UAC issues). Use C:\DevExpress\v19.1.2\Sources instead.
  2. Verify file structure: Ensure you see folders like ExpressBars, ExpressDocking, ExpressGrid, and DxAutoInstaller.exe.

Step 3: Configuration

  1. In DxAutoInstaller, click "Add DevExpress Version".
  2. Specify the root path: C:\DevExpress\19.1.2\FullSource.
  3. Check the box for "Full Source Mode".
  4. Select your target IDEs from the list (e.g., "RAD Studio 10.3 Rio").
  5. Under Build Options, choose:
    • DCU output: Separate folder per IDE
    • Compile in parallel: Yes (max 2 processes)
    • Clean before build: Yes
