Simple Visitor Feedback Application

This application has designed for get feedback on “Dayata Kirula 2011 exhibition” in the BIIT stall.

This application has developed by using Microsoft Expression Blend and Windows Presentation Framework. To design the GUI in WPF it used XAML language. And all the feedback texts will save in the access database. Try to develop this application and it will useful someday.

this is the GUI before submit any feedback.

this is after comment.

Here is the code behind the GUI.I have used C# to code this project and you can use either C# or VB.Net to code this. You want to download and install .net framework 4 to run this application and you want visual studio 2010 to edit this project.

C# code…..

using System.Windows;
using System.Data.OleDb;namespace comment

public partial class MainWindow : Window
OleDbConnection conn = new OleDbConnection();
string [] fname = new string[5]; // decalre array for store first name
string[] comment = new string[5];// declare array forstore second name
int count = 0; // define and initialize the count variable

public MainWindow()


public void clear()
txtaddress.Text =””; // clear all the fields after insert data
txtcomment.Text = “”;
txtemail.Text = “”;
txtfname.Text = “”;
txtlname.Text = “”;
txttelephone.Text = “”;


private void submit_clicked(object sender, System.Windows.RoutedEventArgs e)
string query = “INSERT INTO usercomment(FName,LName,Address,Email,TP,Comment)
VALUES( ‘” + txtfname.Text + “‘,'” + txtlname.Text + “‘,'” + txtaddress.Text +
“‘,'” + txtemail.Text + “‘,'” + txttelephone.Text + “‘,'” + txtcomment.Text + “‘)”;

// sql statement to insert data from text boxes

connection con = new connection();// create new object
conn = con.mycon();// get the connection
OleDbCommand insrtcommand = new OleDbCommand(query, conn);

conn.Open();// open the connection

int countd = insrtcommand.ExecuteNonQuery();

if (count > 4)
// if the count value greater than 4 set value 0 to count variable
count = 0;

fname[count] = txtfname.Text; // getting data from user and store those data in a array
comment[count] = txtcomment.Text;

// display data in the right coloum labels

lblonename.Text = fname[0];
lbltwoname.Text = fname[1];
lblthreename.Text = fname[2];
lblfourname.Text = fname[3];
lblfivename.Text = fname[4];

lblonecomment.Text = comment[0];
lbltwocomment.Text = comment[1];
lblthreecomment.Text = comment[2];
lblfourcomment.Text = comment[3];
lblfivecomment.Text = comment[4];

count = count + 1; // increas the value by one


catch (OleDbException ex)

MessageBox.Show(ex.Message);// if the exception coccure handle it

conn.Close(); // close the connection

clear();// call the method

private void btnClose_Click(object sender, RoutedEventArgs e)

// close the window

private void btnMin_Click(object sender, RoutedEventArgs e)
this.WindowState = WindowState.Minimized;
// minimize the window
