hi, I now writing a activeX control and want to define some constant which is able to use by the program which include this dll. e.g. I may define a constant pi=3.1416 and name this dll to Math.dll. Then I new a project and add it to reference, I could able to use the constant pi.

I have new a module and add a public constant, but this don't work, so what should I do?

Thank!
