I use registry to find things. Stealth auto-detects RTB and Blockland at the first start. Check the newsletter for more information on Stealth IMMC. The web-browser was not hard to make, but IMMC was not easy.
Registry? I've tried accessing the Registry before to save settings instead of just .dat files, and failed. I will have to check for another way. But for now the Blockland folder is located manually.
Also, about newsletters I have tried. Its possible, but there is a problem with downloading files, so I am having in my "WIP" or "Abandoned" project folder that I keep for later use.
Honestly though(sorry for the double posts), the Web Browser is the simplest feature Stealth offers. IMMC was hard because some things require an SQL Query to get information. I had to do that without lagging Stealth at all.
Web browser is pretty much a drag and drop with the fewest of code. IE and Firefox might have 500 > lines code as far as I know (Depending what language its built on)
