Define constant

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!

Add a new Basic Module file and just declare as

VB Code:

Public Const pi As Double = 3.1416

or you can declare under the UserControl source file :)
regards,

Thank Chris, but if I use public constant, it constant will only available within the class. I have got the solution from the other, I should use "Public Enum". but anyway, thank for your help!
