Hello, >A few years back I was programming in MS Visual C++. I remember coming across an article on MSDN where MS said to stay away from inheriting more than 2 levels away from the superclass. example, >Superclass--->Inherited Class--->Inherited Class >They said there was a speed degradation if you tried to inherit anymore after that. I haven't looked into for awhile, have you heard anything similar about this? I've read an article from Codebook newsletter where the author (Charles Blankenship) told that he made tests on 10 level inherited objects against superclass level and didn't get any visible perfomance's degrade. I believe that it's truth (I didn't make my own tests yet)...
