MySQL Data Access Components (MyDAC) is a library of components that provides direct access to MySQL from Delphi, C++Builder, Lazarus (and Free Pascal) on Windows, Mac OS X, iOS, Android, Linux, and FreeBSD for both 32-bit and 64-bit platforms. Applications based on MyDAC can connect directly to MySQL server or work through the MySQL client library. MyDAC is designed to help programmers develop faster and cleaner MySQL database applications. MyDAC is a complete replacement for standard MySQL connectivity solutions and presents an efficient alternative to the Borland Database Engine (BDE) and standard dbExpress driver for access to MySQL.

ZylIdleTimer is a Delphi & C++Builder event driven component which lets you to take actions after a specified system-wide (related to the whole system) or application (related only to the application) idle time or to check the time interval of user inactivity.

In this interval any user action is missing on the computer, like pressing a key of the keyboard or moving the mouse or pressing a mouse button or rotating the scroll. Application Idle time is the time interval of user inactivity inside of one application. In this interval the user doesn't press a key of the keyboard or a mouse button inside of one window of the application.

ZylGSM is a Delphi & C++Builder component that communicates with a GSM modem or phone with integrated modem. This component works with AT (Hayes) compilant GSM modems connected to one of the serial ports. You can use it also with USB, IrDA and bluetooth devices, because these devices have a driver that redirects the input from the USB, IrDA or bluetooth port to a virtual serial port (you can check it in System/Device Manager/Modems).
