:
you have a form
get the text box value into a string
call string.TrimEnd
if string.length > 0 then
you have an inputted string
else
no inputted string
end if

I would strongly suggest you limit the length of the text box
and add some code to determine if the inputted string is valid
e.g. STATE: MARYLAND vs. MD vs. MARY

If textbox.Text = string.empty then
'Nothing Entered
else
'Something entered.
endif
