And I am using this query in ms access 2013
create table pkd(EID int,First_Name char(10),Last_Name char(10),Picture image ).
So question is that when i insert the image it will inserted but when i retrieve its says record not found.
using System.Data.OleDb;
using System.IO;
namespace WindowsFormsApplication6
{
public partial class Form1 : Form
{
OleDbConnection cn = new OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=G:\\Msaccess.accdb");
OleDbCommand command;
string imgLoc = "";
public Form1()
{
InitializeComponent();
}
private void button3_Click(object sender, EventArgs e)
{
try
{
OpenFileDialog dlg = new OpenFileDialog();
dlg.Filter = "jpeg|*.jpg|bmp|*.bmp|all files|*.*";
dlg.Title = "Select Employee Picture";
if (dlg.ShowDialog() == DialogResult.OK)
{
imgLoc = dlg.FileName.ToString();
pictureBox1.ImageLocation = imgLoc;
}
}
catch (Exception)
{
MessageBox.Show("Please enter the valid image.");
}
}
private void button2_Click(object sender, EventArgs e)
{
try
{
byte[] img = null;
FileStream fs = new FileStream(imgLoc, FileMode.Open, FileAccess.Read);
BinaryReader br = new BinaryReader(fs);
img = br.ReadBytes((int)fs.Length);
string sql = "INSERT INTO pkd(EID,FIRST_NAME,LAST_NAME,PICTURE)VALUES('" + textBox1.Text + "','" + textBox2.Text + "','" + textBox3.Text + "',@img)"; // string values
if (cn.State != ConnectionState.Open)
cn.Open();
command = new OleDbCommand(sql, cn);
command.Parameters.Add(new OleDbParameter("@img", img));
command.ExecuteNonQuery();
cn.Close();
MessageBox.Show("Record(s) Saved.");
}
catch (Exception)
{
cn.Close();
MessageBox.Show("Insertion Failed");
}
}
private void button1_Click(object sender, EventArgs e)
{
try
{
string sql = "SELECT FIRST_NAME,LAST_NAME,PICTURE FROM pkd WHERE EId='" + textBox1.Text + "'";
cn.Open();
command = new OleDbCommand(sql, cn);
OleDbDataReader reader = command.ExecuteReader();
reader.Read();
if (reader.HasRows)
{
textBox2.Text = reader[0].ToString();
textBox3.Text = reader[1].ToString();
byte[] img = (byte[])(reader[2]);
if (img == null)
pictureBox1.Image = null;
else
{
MemoryStream ms = new MemoryStream(img);
pictureBox1.Image = Image.FromStream(ms);
MessageBox.Show("Search SuccessFul.");
}
}
else
{
MessageBox.Show("Id Doesnot exists");
}
cn.Close();
}
catch (Exception)
{
cn.Close();
MessageBox.Show("Id Does not Exists.");
}
}
}
}

string sql = "SELECT FIRST_NAME,LAST_NAME,PICTURE FROM pkd WHERE EId=" + textBox1.Text;

Yeah it is inserting in database but when i retrieve its shows id doesn't exits.

Although EID is an int column, you're enclosing it in single quotes.
Generally, when you use parameters with Access, instead of the name (@img here) you'd just use a question mark, ?, in the command.
So are you sure that the record is being correctly inserted in the Access table?
