Yes and No.
If the value is calculated in a query then I can't think of a way.
If the value is calculated in the control then you would need to write VBA
that would step through all the controls on forms and reports and look for an
equal sign at the beginning of the control source. Of course, you would need
to only check those controls (text boxes and comboboxes and ?) that do have a
control source property.
This would also miss those controls that were unbound (blank control source
property) and got values assigned via VBA code.
I don't have such code available.
