function pushbutton​1_Callback​(hObject, eventdata, handles)

 function pushbutton1_Callback(hObject, eventdata, handles)
handles.metricdata.a=1;
function pushbutton2_Callback(hObject, eventdata, handles)
b=handles.metricdata.a;
if(b~=1)
   msgbox('ok');
end
if(b==1)
   msgbox('false');
end

in above code, if i don't press pushbutton1 and i press pushbutton2 then message 'ok' should display and if i press pushbutton1 and i press pushbutton2 then message 'false' should display.

In function pushbutton1_Callback you should update your handles

handles.metricdata.a=1;
guidata(hObject,handles)

[vipul utsav]

it is right for pushbutton1 pressed,and 'false' display but wrong for pushbutton1 is not pressed and nothing display in place of 'ok'

[Azzi Abdelmalek]

You did not Answer my question, have you updated your handles with guidata, also, have you initialized handles.metricdata.a in your opening function?

[vipul utsav]

yes,i update data using guidata. and i initialize 'handles.metricdata.a=0'

but problem is there is that every times 'b' become '1',but i want b is different for pushbutton1 is pressed and not pressed

[Azzi Abdelmalek]

In your yourfilename_OpeningFcn

handles.metricdata.a=0;
guidata(hObject,handles)

In

function pushbutton1_Callback(hObject, eventdata, handles)
handles.metricdata.a=1;
guidata(hObject,handles)

In

function pushbutton2_Callback(hObject, eventdata, handles)
b=handles.metricdata.a;
if(b~=1)
 msgbox('ok');
end
if(b==1)
 msgbox('false');
end
