how can i show a numerical output in gui

i am using the following gui code

function guitrial
voltageH = uicontrol('Style', 'PushButton', 'String', 'Voltage', ...
                   'Position', [10, 200, 100, 24], ...
                   'Callback', {@dataaq});
ValueH = uicontrol('Style', 'edit', 'String', '0', ...
                   'Position', [10, 150, 100, 24]);

here the callback function gives a numerical result (that i put in a variable) but it is shown in the command window.how can i get the result in the static box? it will be very helpful if you give me the code or example.thanks

Give this a try:

function guitrial
S.voltageH = uicontrol('Style', 'PushButton',...
                       'String', 'Voltage', ...
                       'Position', [10, 200, 100, 24], ...
                       'Callback', {@dataaq});
S.ValueH = uicontrol('Style', 'edit', 'String', '0', ...
                     'Position', [10, 150, 100, 24]);
guidata(gcf,S)               

function [] = dataaq(varargin)

D = randi(10);  % Say your program returns this.
S = guidata(gcbf);
set(S.ValueH,'string',num2str(D));
