function varargout = lbox2(varargin) % LBOX2 Application M-file for lbox2.fig % LBOX2, by itself, creates a new LBOX2 or raises the existing % singleton*. % % H = LBOX2 returns the handle to a new LBOX2 or the handle to % the existing singleton*. % % LBOX2('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in LBOX2.M with the given input arguments. % % LBOX2('Property','Value',...) creates a new LBOX2 or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before lbox2_OpeningFunction gets called. An % unrecognized property name or invalid value makes property application % stop.

@Arun: It is not useful to post a pile of unformatted code. In opposite it makes reading this thread harder such that this reduces the chance to get a helpful answer. Therefore it is recommended to post a minimal code snippet only, which reproduces the mentioned problem.

The explanation "I am unable" does not allow for an efficient answer, because we have to guess too much what's actually happening when your program runs.
