How to display image in PictureBox from database. I'm working .NET window application. I wrote code for this problem but I got error.
Please solve my problem or tell me other solution.

C#

        private void button4_Click(object sender, EventArgs e)
        {
            con.Open();
            cmd = new SqlCommand("select * from tblImage where ID=2", con);
            SqlDataReader dr = cmd.ExecuteReader();
            while (dr.Read())
            {
                byte[] b = new byte[0];
                b = (Byte[])(dr["ImgUrl"]);
                MemoryStream ms = new MemoryStream(b);
                pictureBox1.Image = Image.FromStream(ms);
                //pictureBox1.Image = Convert.ToSByte(dr["Url"].ToString());

}
            con.Close();
        }

Solution 1

The column name in your table seems to say "Hey I'm the url to an image that's why they called me ImgUrl". Looking at the code on the other hand seems to imply that the image itself is stored in the database and not some url to an image.

So what type is column ImgUrl?
And as Umair already said please post the error message in your question.

Regards,
Manfred

           string getpwd = textBox3.Text.ToString();
           string query2 = "select * from Table1 where Filename= '" + getpwd + "'";
           Console.Write(query2);
           OleDbCommand s = new OleDbCommand(query2, conn);
           OleDbDataReader bReader = s.ExecuteReader();
