Description

Random number sequences generated in Delphi using the native Random function leave much to be desired. By default the same number sequence is produced each time the parent application is run. Matters can be improved to a certain extent by seeding the random number generator using the system clock by calling the Randomize function.

However, this does not change the fact that the algorithm used is quite simplistic. Algorithms of greater complexity that claim to yield more random sequences abound. However, it is not really necessary to code such an algorithm. Windows comes with an intrinsic random number generator in the form of the CoCreateGUID function. We demonstrate how it can be used with a minimum of coding to create a truly robust sequence of pseudo-random numbers.
