cam on ban nha, minh lam duoc roi.
mình cũng sắp hoàn tất, nhưng 1 vấn đề mình ko biết làm đó là nút( Chấm Công), mình ko biết làm sao, xin các bạn chỉ giúp mình nha, mail minh là: nhattrung21@yahoo.com
function varargout = trunglam(varargin)
% TRUNGLAM M-file for trunglam.fig
% TRUNGLAM, by itself, creates a new TRUNGLAM or raises the existing
% singleton*.
%
% H = TRUNGLAM returns the handle to a new TRUNGLAM or the handle to
% the existing singleton*.
%
% TRUNGLAM(‘CALLBACK’,hObject,eventData,handles,…) calls the local
% function named CALLBACK in TRUNGLAM.M with the given input arguments.
%
% TRUNGLAM(‘Property’,'Value’,…) creates a new TRUNGLAM or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before trunglam_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to trunglam_OpeningFcn via varargin.

% *See GUI Options on GUIDE’s Tools menu. Choose “GUI allows only one
% instance to run (singleton)”.
