Can activex dlls be used in vb6 as i cant find out how to call them and use functions, i've got some basic code to test with.

The code in my activex dll(AdditionHelper.dll) in the(Addme.cls):
Code:
Public FirstNumber As Variant
Public SecondNumber As Variant

Function AdditionFunction(FirstNumber, SecondNumber)
    AdditionFunction = FirstNumber + SecondNumber
End Function
i'd like to know how to call this dll from my app to use the code

thanks in advance
