Tab Page containing current control

[Larry]

I pass a control to a subroutine for some validation. Depending on what the
subroutine finds, I want to modify the tab page on which the control resides
to have an asterisk next to the tab label.

Is there an easy way to find on which tab page, the current control is
located?

I know I can go through every control on every page, but that can take a
long time. I'm hoping there is another way to find the container for the
current control.

Any suggestions?
