typedef BYTE T;

Hi Michael,

the above row At[ ind3,ind2,ind1 ] always call the function get_At[ ind 1

].
According to the rules of C++ the above code is working as expected. C++
does have built-in support multi-dimensional arrays and thus a[e1, e2, e3]
is treated as a[(e1, e2, e3)], or once you apply the comma-expression rules
a[e3];

By the way, for Whidbey the compiler will be supporting multi-dimensional
CLR arrays and so with this release a[e1, e2, e3] will work the way the
user expects it to work.
Thanks!

Just to make sure we don't confuse readers:

is treated as a[(e1, e2, e3)], or once you apply the comma-expression
rules
a[e3]; Gary meant to say that C++ does __NOT__ have built in rectangular
multi-dimensional arrays.

And if anyone is less familiar with the comma operator, it evaluates all
arguments left to right and then returns the last one.

Thanks.

Hi, Michael:

Here is what I have found out from the book <<Essential Guide to Managed
Extenstions for C++>> by Siva Challa:

A good property behaves like a data member. But there is things that we can
do with a data member but not with a property.

"An array property declaration shall not overload an indexed property."
Otherwise, we will have ambiguity problem.

It looks from your code, you have overloaded the array property. I would
suggest you to avoid overloading here.

Thanks!

Sally Lou
