Hello everyone,
Yet another library from early last year whilst I was trying to learn more about B4X libraries. This is not converted from an existing library, all methods were written from scratch. I created this library for myself, as I was creating a personal app and needed three or four of these functions. After finishing my personal project, I crazily decided to expand the functinality of the library.
This library provides a broad and practical collection of Win32 functionality for B4J developers who want deeper access to the Windows platform without writing native code. It is built on top of JNA and exposes a clean, consistent set of methods that cover window management, clipboard access, system information, power control, services, input simulation and more. The aim is to make common Windows tasks simple to call from B4J while keeping everything reliable and easy to integrate.
The library includes full support for working with windows, monitors and the desktop environment. You can retrieve titles, handles and class names, move and resize windows, control visibility and topmost state, and enumerate all visible windows. It also provides access to screen metrics, taskbar information and monitor layouts, which makes it useful for multi screen applications and layout aware tools (I believe).
Beyond window control, the library offers a wide range of system level features. These include clipboard text handling, registry access under HKCU, environment variables, file attributes, process information, system uptime, memory statistics and power management commands. There is also support for Windows services, allowing you to check for service existence and query service status directly from B4J.
The goal of this release is to give B4J developers a dependable and well structured way to interact with Windows at a low level while keeping the code readable and straightforward. You can focus on building your application rather than dealing with native API details.
Please note:
Some functions may trigger Windows security prompts or require elevated permissions depending on system configuration. This is normal behaviour for certain Win32 APIs.

Version: 1.0
The attached example will start notepad (in two different ways), cmd window, and the calculator.
Enjoy...
