I did not tried it at the time of my post, since I had the worry that
it's a sort of "poprietary" code that is not included in full source
license from Jason Wharton (...The source code for these components is
being released for demonstration, testing and evaluation purposes only
at this stage...).
Anyway, experimenting with TEditEnh I've found that:
a) there is no a drop down calculator (of course! :))
b) no currency conversion (I need it for Euro transition stuff)
But it gives me 90% of the functionality I need, so it would be a very
good starting point for a less general, more specific and somewhat
enhanced specialized currency control.

Using the IB_Query property editor, I can find the "Edit mask"
property, but not the "Mask mode"... any suggestion?

Thanks for the suggestion :) I will wait for your answer regarding
reusing YOUR code and your source license, since it would be better
for the IBO community having a common base tree wherever possible.
Have a look to my message about decimal separator, please, since it's
a real need for many internationa users. I'm sure you will fix
it. Thanks
