Welcome!

Welcome to the web site of Andreas Rozek. After a long period of inactivity the author has now finally begun to continuously reconstruct his web appearance. Currently, the list of (new or modified) topics is still quite short, but this will hopefully change in the near future...

Overview

The following topics are currently available - just click on an article of your choice:

	ExpressionParser - evaluating numerical expressions with ActionScript 3 Since version 3, ActionScript definitely lacks any kind of "eval" function. If you used this function to analyse and evaluate numerical expressions before, you may benefit from the author's "ExpressionParser", a small class which provides just this functionality.
	ExpressionParser - evaluating numerical expressions with RunRev Occasionally, it is necessary to analyse and evaluate numerical expressions at run-time. The author's "ExpressionParser" is a small and simple "Library Stack" for Runtime Revolution, which provides an (extensible) "sandbox" for that purpose.
	FileInfo - an "External" for Runtime Revolution In order to determine the properties of a single file using Runtime Revolution, it is first necessary to determine the properties of all files in the containing folder and then to filter out the actually desired information. The author's "External" for Windows, Linux and MacOS X offers a more efficient approach!
	PreloaderDisplay - a Preloader Display for Flex Applications Because of their size Flex applications usually take some time to load and initialize. A small preloader display (which may be easily embedded into your own Flex projects) provides valuable feedback for the user during this loading phase.
	FTIStrap - a fully functioning 3D Printer built using fischertechnik 3D Printers are machines which automatically construct real-world objects based on (virtual) computer models. Follow the link to see how you can build such a (rapid prototyping) device yourself!
	VBA for Excel - Presentations and Exercises (in german only) At the beginning of every semester break, the author usually gives the course "VBA for Excel" (with exercises) at the Hochschule für Technik in Stuttgart. Following the actual course, you may still access the accompanying material (i.e., the presentations and the exercises) if you click on the link.
