Target your own devices and platforms with Extensibility API

Full Convert is the easiest way to copy your data from one database to another - and blazingly fast. Databases can be messy. We support all popular and even ancient databases of any size with all complexity hidden away so you can get the job done now. Full Convert will quickly and easily copy your data from source to the target database. It will create all the tables, copy all of your data, then create indexes and foreign keys.

A Bluetooth Low Energy component library providing straightforward access to BLE operations. The IPWorks BLE components provide simple service discovery and access to BLE-enabled devices. IPWorks BLE includes a set of powerful components for integrating Bluetooth Low Energy communications capabilities into web, desktop, and mobile applications. The BLEClient component provides a simple but flexible BLE GATT client implementation, making it easy to work with the services, characteristics, and descriptors exposed by BLE GATT servers on BLE devices.

StyleControls is a stable, powerful package (more than 100 components), which uses Classic drawing, system Themes, GDI+ and VCL Styles. This package contains the unique solutions to extend standard VCL controls and also has many unique, advanced controls to create modern applications (UWP design). Also with this package you can really improve applying and using of VCL Styles in your application.

The new Next Generation (NG) Control Suite supplements the LMD line of products for Embarcadero Delphi/C++Builder. While LMD VCL products still (now and in the future) support legacy IDEs (Delphi/C++Builder 6 and higher), NG components make use of new IDE and language features of most recent IDE releases (Delphi/C++Builder 2009 and above). This approach allows us to neglect compatibility issues (e.g. Unicode and Generics support) and to use ideas which are not possible with older IDEs. Besides that NG Controls are designed to be lightweight and task-focused. They do not represent a complete framework like the LMD VCL platform and can be used at the same time with LMD VCL controls, the VCL or any other 3rd Party toolbox.

TdxServerModeCustomDataSource class support UniDAC. It is sufficient to override some of TdxServerModeCustomDataSource methods to implement this functionality. Attached is a .pas file that shows how it can be done. Just add this unit to the uses section of your project and write the code similar.

SpreadsheetGear for .NET Standard enables developers for iOS, Android, Linux, macOS and UWP to easily take advantage of scalable Excel Reporting, comprehensive Excel compatible charting APIs, the fastest and most complete Excel compatible calculations and more using a single assembly which implements the same API employed by thousands of Windows developers for more than a decade.
