Query: Horrible book

I have to agree with the rest of the reviews. The circuits may be simple but the code for talking to them is written in VB 4.0. The problem with this is that it makes it very difficult to talk to the serial and parallel ports because they included two dll's (which contain all the manditory code to talk to the ports) when they should have just included the code for them inside the main module of the program (at least then we may have been able to see how in the heck the programs talk to the ports.) Windows 95 and above versions talk differently to the serial and parallel ports than what the software included with the projects does. You may build some neat circuits, but don't expect to be able to control them from the included software. I have had to rewrite each and every individual program in Visual C++. I am a computer science major and this was even difficult for me. I don't recommend this book at all!
