| The CronJob component is the thread-based alarm implementation for Delphi/BCB which acts like cronjob utility in Unix. The component produces periodical OnAlert events by schedule specified in CRON format (actually it uses extended CRON format with new "seconds" field, to let the event to be triggered even every second). To specify the moments when the component should trigger the OnAlert event, the component uses the CRON format (all who worked in Unix must be aware about this utility, this is daemon of scheduled, periodically executed tasks). The authors of CronJob component has very liked an idea of describing the periodical events of any complexity, tiered to astronomical time, in simple text string. We have used slightly modified CRON format, added seconds field and altered the rules of describing the lists of numbers. The package includes 2 bonus components: * AccurateTimer -- thread-based timer which periodically triggers the OnTimer events by specified Interval, but unlike standard TTimer, which based on Win32API and thus loses timer messages on high application overload, this timer runs in the separate thread and accurately triggers each OnTimer event at right time. It also allows to specify the Interval with higher precision (less than 55msec, limited in Win9x) and does not dependent to the system-wide limitations.) * AwayTimer -- monitors user activity and increase its time counter when keyboard and mouse are inactive (user distracted from PC or goes away). Also it triggers special event when system is about to start the screensaver, or after some defined period of user inactivity. Added: 7-06-2004/20-12-2004 | Version: 1.2.1 | Downloads: 88/87/0

| The TKAParser component is an expression parser, calculator and spread sheet engine. It can (1) Evaluate mathematical and string expressions that contain numbers, predefined variables and formulas. A mathematical expression may have any commonly used math functions. A string expression may have any commonly used string function. (2) Transparently track formula / variable dependencies. Consequently, the parser needs to re-evaluates a formula only when the value of a dependent variable changes, a feature that enables it to perform hundreds of complex expression evaluations every second. A caching mechanism further optimizes expression evaluation making the parser#well# Kick Ass! · Work with any number of user defined functions. (3) Gracefully handle undefined variables by assigning default user defined value Added: 26-03-2000 | Version: 1.02 | Downloads: 1937/1937/0

| The unit STATIS offers some of the most fundamental procedures of mathematical statistics. Along with the Gamma and the Beta function, all major types of distributions are implemented (normal, t, F, and chi-square distribution). registration fee US$ 12, sources for US$ 80 Added: 13-09-1998 | Version: 1.0 | Downloads: 2234/2234/0
