I'm not knowledgeable enough to answer that. I believe the number of subclasses is unlimited, but don't quote me. I know that C# supports single class inheritance only - you can specify only one base class to inherit from. However, it does allow multiple interface inheritance. You just can't inherit from multiple base classes (you have to use an interface and dup all base classes). There was a discussion here on the UT about it. The biggest issue was that most see using multiple inheritence as bad design. I think if the business need warrants it, do it. I certainly don't want to open that can of worms again! :o)



>>There is no visual method of subclassing in C# (like the gui visual method of subclassing in vfp) - it can only be done by typing code.
