Error while Image loading from database

Question

I'am using generic handler for loading Image from data bases. Its work fine when when I hardcode the ImageID in QureyString when call Handler. But it's giving errors of different type when I dynamically pass value to qurey string(from datatable).
"There is already an open DataReader associated with this Command which must be closed first." 
OR
"There is already an open DataReader associated with this Command which must be closed first."
here is a code of Handler
public void ProcessRequest(HttpContext context)
Int64 id = Convert.ToInt64(HttpContext.Current.Request.QueryString["adid"]);
// dt = obj_dalayer.GetRecpDetailsByID(id);
dt=GetRecpDetailsByID(id);
if (dt.Rows.Count > 0)
//context.Response.ContentType = "image/jpeg";
context.Response.BinaryWrite((byte[])dt.Rows[0][2]);
public DataTable GetRecpDetailsByID(Int64 reid)
try
obj_DB.Open();
obj_sqlcmd = new SqlCommand("GetRecpDetailsByID", obj_DB.GetDBConnection());
obj_sqlcmd.CommandType = CommandType.StoredProcedure;
obj_sqlcmd.Parameters.Add(new SqlParameter("@rid", reid));
obj_sqlda = new SqlDataAdapter();
obj_dt = new DataTable();
obj_sqlda.SelectCommand = obj_sqlcmd;
obj_sqlda.Fill(obj_dt);
return obj_dt;
finally
obj_DB.Close();
And here is a HTML and ServerSide code on ASPX page of call handler.
<img id="img2" alt="Image" runat="server" src='<%#"~/ImageReqHandler.ashx?adid="+Eval("ReID")%>' width="179" height="148" /
I'm using Eval("ReID") to get ID of Image from datatable.

Ayez,
This is the VB forum, try it in the C# form.

However, there they will probably tell you that although your problem is C#, it is ASP.Net some programmers become scared if it is Web you know.
