Re: Access user input from command line

A rookie question here...

I am trying to create a GUI with an edit box for user input
and a push button which the user will press to "submit"
their input (I call the program "enter"). I then want to
manipulate this data through the command prompt (or another
m file).

I am unable to call the input (called "str" in the code
below) in the command prompt or through other m files (I get
the error: ??? Undefined function or variable 'str'.). My
code is below (the input is declared near the bottom of the
program):


function varargout = enter(varargin)

% ENTER M-file for enter.fig
% ENTER, by itself, creates a new ENTER or raises the
existing
% singleton*.
%
% H = ENTER returns the handle to a new ENTER or the
handle to
% the existing singleton*.
%
% ENTER('CALLBACK',hObject,eventData,handles,...) calls
the local
% function named CALLBACK in ENTER.M with the given
input arguments.
%
% ENTER('Property','Value',...) creates a new ENTER or
raises the
% existing singleton*. Starting from the left,
property value pairs are
% applied to the GUI before enter_OpeningFunction gets
called. An
% unrecognized property name or invalid value makes
property application
% stop. All inputs are passed to enter_OpeningFcn via
varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI
allows only one
% instance to run (singleton)".
%
% See also: GUIDE, GUIDATA, GUIHANDLES

I know, its pretty pathetic...can anyone help?


Hai,
If u want to access the string from command prompt use
evalin command. If u want to access it from the another GUI
or m_file use the command findobj.

one more method is to make the string global variable and
call it from anywhere in m_file or from any file in the
current working directory.
