Hi Nacho,

If you check the Object Browser you'll discover that CDbl is not a
property or method of a class, so you can't run it using CallByName. I'm not
clear why you would want to do so anyway, since CDbl is a global function
that can be used directly from anywhere in a VBA program.

Hello,

This is something that I should have known in the VB basics, but I didn't
and also it's not very Excel specific, but beacuse I am doing it in the
Excel context I guess it's relevant here.

I have the following call:

SomeFunction = CallByName(VBA, "CDbl", VbMethod, inputValue)

The problem is that I don't know the object in which the CDbl is defined.
Using VBA returns compiler error. I need to use this because "CDbl" will
be
parameterized.

Thanks for you time,
Nacho
