However, why bother with visual components that are 'not-so-input-friendly when everything we want is just one Edit box to type the date into.
In this article you will find one great function designed to make date processing a bit faster.
Understanding Recursive Functions
Recursion is a general method of solving problems by reducing them to simpler problems of a similar type. A recursive subroutine constantly calls itself, each time in a simpler situation, until it gets to the trivial case, at which point it stops. Learn how to write recursive functions in Delphi.
How to Convert Numbers (Currency) to Words
A sample code to convert (depending on the real type used) positive and negative real values up to 1.00E18 to the English words. The return value can represent either currency or numerals. For example 1234.567 will be returned as either "one thousand, two hundred and thirty four dollars and fifty six cents". Full Delphi source code included.
How to Create a Stub Program to support Self-Extracting Archives
