how to get string for empty Edit Text in Matlab GUI ?

Hi,
I inserted an Edit Text in a Matlab GUI, and I would like to perform some actions when nothing is in the Edit Text (Edit Text empty). I have the following:
extractPass=get(handles.inputPassword_txt,'string');
The problem is that, when the Edit Text is empty, isempty(extractPass)= 0. I was expecting isempty(extractPass)=1 when the Edit Text is empty.
What do I need to write to know when the Edit Text is empty ?
Thanks.

With R2012a I fail to reproduce your problem. Try
class( extractPass )
double( extractPass )
to find out what get returns

You have a < 2x1 cell> array of strings (or something else). Try this
extractPass{1}
extractPass{2}
whos extractPass
for ii = 1 : numel( extractPass )
class( extractPass{ii} )
isempty( extractPass{ii} )
end
or use the variable editor to find out what is in the cells.
Do you have a squeezed scroll bar to the right end of the edit box?
