1. Introduction

This is our first individual assignment for Programming unit this semester. This assignment was given in December 2013, and submission date is on 10th February 2014.
In this assignment, we were asked to create and design a Photo Viewer application. This application should be able to allow the users to browse through pre-loaded images. Programming will be done using Visual Basic.NET 2008 software.
At the end of the assignment, we should be able to produce documentation on Photo Viewer application.

Here is the coding listing for Form 1:

Public Class Form1 Dim filename As String Dim strdirectory As String = "\VB\Photo Viewer\"

Dim opentext As StreamWriter If File.Exists(strdirectory & "photos.txt") Then opentext = File.AppendText(strdirectory & "photos.txt") Else opentext = File.CreateText(strdirectory & "photos.txt") End If

opentext.WriteLine(txtimgno.Text) opentext.WriteLine(txtcaption.Text) opentext.WriteLine(txtdate.Text) opentext.WriteLine(rtbDescription.Text) opentext.WriteLine() opentext.Close() pbxPhoto.Image.Save(strdirectory & "images\" & txtimgno.Text & ".jpg") MsgBox("Image saved!", MsgBoxStyle.Information) gbxDetails.Enabled = False btnSAVE.Enabled = False btnCancel.Enabled = False gbxDetails.Enabled = False btnADD.Enabled = True btnVIEW.Enabled = True btnExit.Enabled = True
