ZylTimer is a high resolution, long-term Delphi & C++Builder timer component which provides a higher precision than the standard Delphi / C++ Builder TTimer component. TTimer component which ships with Delphi & C++Builder uses the Windows Message Queue to generate the OnTimer event. Due to this approach it's impossible to get accurate timer intervals smaller than 15 milliseconds. ZylTimer is a thread based timer and due to this architecture provides a higher precision (1-2 milliseconds), which is inevitable in time critical applications. The standard TTimer component uses the SetTimer API function, so the interval is limited to 2147483647 milliseconds (about 25 days). ZylTimer is a thread based timer and the interval could be set even to hundred years if necessary. It is important to understand that the accuracy of timers is limited. Windows is not a real-time operating system (except Windows CE) and it is not reasonable to expect timers to handle exactly very small time intervals.

The must-have productivity tool for Visual Studio, ReSharper 5 provides solution-wide error highlighting on the fly, advanced code completion, superior unit testing tools, over 30 advanced code refactorings, multiple handy navigation and search utilities, single-click code formatting and cleanup, automatic code generation and templates, and a lot more productivity features for C#, VB.NET, ASP.NET, XML, and XAML. ReSharper fully integrates with Visual Studio to intelligently and powerfully extend the functionality that is native to Visual Studio.

Whenever a developer tries to use a component or a tool that renders text, then he/she has to deal with fonts. Whether the component is a GUI control such as a text label or a text box, or a non-GUI component that renders text on a printer canvas, it must be able to process fonts. Here, the choice of fonts that can be used with the component is limited to those that are installed on the system and also by the font types supported by the run-time environment (.NET and JRE). What if you wanted to use a font that is not installed or if you wanted to use a font type that is not supported by the run time?

HTML Viewer Components for Delphi, Lazarus and C++Builder

The HtmlViewer component set consists of the THtmlViewer, TFrameViewer,
and TFrameBrowser components. All three are HTML document display components:

CadoDraw is a system of Delphi components which is primarily programmed using settings in the Objekt Inspektor.

ZylIdleTimer is a Delphi & C++Builder 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. System Idle time is the time interval of full 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.

ZylGPSReceiver is an award-winning Delphi & C++Builder component collection that communicates with a GPS receiver (Global Positioning System).
It returns latitude, longitude, altitude, speed, heading and many other useful parameters of the current position and the parameters of the satellites in view. The component is extended to calculate distances and make conversions between different measurement units. This component works with any NMEA 0183 compilant GPS receiver connected to one of the serial ports. NMEA 0183 (or NMEA for short) is a combined electrical and data specification for communication between marine electronic devices such as echo sounder, sonars, Anemometer (winds speed and direction), gyrocompass, autopilot, GPS receivers and many other types of instruments. It has been defined by, and is controlled by, the US-based National Marine Electronics Association. 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/Ports). If your USB device is not provided with such a driver, then use a USB controller whose vendor provides a virtual serial port driver, such as FTDI or use a USB/RS-232 adapter. For Garmin receivers you have to install Spanner software.

AlphaControls - a set of common and some unique components that support skins (AlphaSkins), as well as having some additional features. All skin elements can have their own properties for advanced drawing the gradient, realistic framework, semi-transparent and blurry shadows. Graphics functions produce all the calculations and drawing in real-time. Added property BoundLabel for editing elements. Handled various mouse events, which gives some additional features components. Manager prompts controls the tips in the application and gives them a beautiful view with a lot of settings that can be changed by a special designer. Analogs of standard components provide all the functionality and add a lot of new solutions to improve software quality and their appearance.
