Dear All,

I have a table named images in SQL Server 2008 and it contains two columns imageid and image.

Now I am able to insert images in to image column using file uploader controller and image which i have converted to binary form for storing.

Now I want to display the images in a image box correspondence with the image id.

I used TextBox for receiving the id and a button to execute the command for displaying. I am using asp.net as front end.

C#

public void ShowImage()
{
    SqlConnection con = new SqlConnection();
    con.ConnectionString = System.Configuration.ConfigurationManager.AppSettings["anu"].ToString();
    SqlCommand cmd = new SqlCommand();
    cmd.CommandText = "Select ID,Image from Images where ID=" + txtid.Text;
    cmd.CommandType = System.Data.CommandType.Text;
    cmd.Connection = con;   
    
    con.Open();
    SqlDataReader dreader = cmd.ExecuteReader();
    dreader.Read();
    Context.Response.BinaryWrite((byte[])dreader["image"]);
    dreader.Close();
    con.Close();
}

This code is working fine, but it displaying the picture in a different page but I need to display the picture in the image box which I have added.

If anyone who know the answer, please help me.

Regards,

img.ashx:

C#

public class img : IHttpHandler
{
    public bool IsReusable
    {
        get
        {
            return false;
        }
    }

    public void ProcessRequest(HttpContext context)
    {
        context.Response.ContentType = "image/png";
        Image i = null;

        //Load image here

        var ms = new MemoryStream();

        i.Save(ms, ImageFormat.Png);
        var msToArray = ms.ToArray();
        context.Response.BinaryWrite(msToArray);

       // 1 year cache
       // TimeSpan refresh = new TimeSpan(365, 0, 0, 15, 0);
       // context.Response.Cache.SetExpires(DateTime.Now.Add(refresh));
       // context.Response.Cache.SetMaxAge(refresh);
       // context.Response.Cache.SetCacheability(HttpCacheability.Public);
       // context.Response.CacheControl = HttpCacheability.Public.ToString();
       // context.Response.Cache.SetValidUntilExpires(true);
    }
