Gytis - rather than attaching a zip file, which many of may be reluctant to open, please attach the m and fig files instead.

You can do

get(findobj('tag','objTagName'),'String')
or 
get(hObject,'String')

where objTagName is the tag you assigned to the uicontrol('Style','edit',...) and hObject is the handle if it was saved.

but i need this get value from database, i try but not working for me, maybe i do somthing wrong?

[mbonus]

setappdata(0,'VarName',VarName)
getappdata(0,'VarName')

Just make sure that you save it to the root directory (0), that way it can be accessed regardless of whether the GUI has been closed

[Gytis Raudonius]

maybe you can explain more how it should be work

function pushbutton1_Callback(hObject, eventdata, handles)
conn = database('baze', 'root', 'root', 'Vendor', 'MYSQL', 'Server', 'localhost', 'PortNumber', 3306);
a = get(handles.edit8,'String');
%b = get(handles.edit9,'String');
if iscell(a) && numel(a) == 1
    a = a{1};
end
if ~ischar(a) || isempty(a);
    error('A valid string must be supplied!');
end
sqlquery = ['select vardas, pavarde, laipsnis, pareigos, telefonas, marke, numeris, tarnyba from info '...
       'where numeris = ' '''' a ''''];
curs = exec(conn, sqlquery);
curs = fetch(curs);
getappdata(handles.edit9,'vardas');
curs.data
close(curs)
close(conn)
