Having said that, this reviewer started writing ObjectARX applications within the first 2-3 weeks of reading the book. The author provides sound basics and good examples. It covers many topics within the ObjectARX environment but does not go into great detail on any particular one. The book assumes that the reader will use the on-line reference to find out the nitty-gritty on a particular item. Admittedly, this reviewer found himself after the first month of programming relying primarily on the on-line reference provided with ObjectARX, rather than the book. Still, the book gets you pointed in the right direction. The biggest complaint this reviewer had, if he had to name one, is the index. It is quite lacking.
Private Sub Command1_Click() MsgBox "Hello World!" End Sub
you have instead two(!) pages of code to even register the Hello World application in the proper ObjectARX (class-based) method. Add to that the fact the the ObjectARX model uses a mind-boggling array of macros, includes, etc, and you will quickly feel out of your depth.
There are VERY good reasons to do ObjectARX programming, most of which have to do with the ability to add your own custom classes to the AutoCAD object model, and creating your own entity types from scratch. If you don't need to do that yet, go get a beginning VC++/MFC book and study that. Meantime, VBA is extremely fast for all but the most demanding applications, and is worth very careful study.
I would also add: AutoCAD has some of the BEST documentation in the world. If you have already downloaded the ObjectARX SDK (which I assume since you are perusing a book about it), don't overlook the excellent documentation in PDF format. Not many people know about it, but it is there if you look.
