I would like to display a From(eg. frmDisplay) while a MDI Form
is alreay running.
The frmDisplay form need to be activated in one of the Command
button in the MDI Form.

I tried the following but in the Click event button in the
MDI form, with error "Object is required"
Load frmDisplay
frmDisplay.Show

The frmDisplay actually display "In Processing..." message while
the MDI Form is doing some processing task. Any other better suggestions?
