Can I have an input mask, that allows phone numbers of style
(999)000-0000 and also allow international numbers not of this style.
Yes and no. The InputMask is only a method for getting in the way of
users' keystrokes: it does not have any effect on the data themselves.
Therefore it would not be too hard to allow the user to manipulate the
control.
For example, use the DoubleClick event to set the InputMask to "", and
optionally change the BackgroundColor to something as a visible reminder.
Use the Form_OnCurrent or control LostFocus event to set the colour and
mask back to whatever you want.
For myself, though, I just hate IMs because they just annoy the user, and
don't protect the data. I blame Paradox...
