ExecuteReader Error A Parameter Is Missing [Paremeter Ordinal = 1]

Hello and thanks in advance.

This error was received executing a SqlCeCommand method of ExecuteReader();

I have only found 3 hits in Google about this error and the time it was asked in a MS forum it was not answered. I need an answer, please.

bombar...see code below


SqlCeDataAdapter adp = null;

adp = new SqlCeDataAdapter();

SqlCeCommand cmd;

cmd = _Con.CreateCommand();

cmd.CommandType = CommandType.Text;

cmd.CommandText = "insert into InventoryCounts(DateTime,WarehouseID,PartID,LotID,UserName,Count) VALUES(?,?,?,?,?,?)";

adp.InsertCommand = cmd;

cmd = _Con.CreateCommand();

cmd.Parameters.Clear();

SqlCeParameter p1 = cmd.Parameters.Add("DateTime",SqlDbType.DateTime);

SqlCeParameter p2 = cmd.Parameters.Add("WarehouseID",SqlDbType.NChar,20);

SqlCeParameter p3 = cmd.Parameters.Add("PartID", SqlDbType.NChar,20);

SqlCeParameter p4 = cmd.Parameters.Add("LotID", SqlDbType.NChar,20);

SqlCeParameter p5 = cmd.Parameters.Add("UserName", SqlDbType.NChar,20);

SqlCeParameter p6 = cmd.Parameters.Add("Count", SqlDbType.Int);

p1.Value = Convert.ToString(DateTime.Now);

p2.Value = "Warehouse1";

p3.Value = txtBPartIDShow.Text;

p4.Value = txtBLotIDEntry.Text;

p5.Value = "JHB";

p6.Value = Convert.ToInt32(txtBCountEntry.Text);



cmd = _Con.CreateCommand();

cmd.CommandType = CommandType.Text;

cmd.CommandText = "insert into InventoryCounts(DateTime,WarehouseID,PartID,LotID,UserName,Count) VALUES(?,?,?,?,?,?)";

cmd.Prepare();

cmd.ExecuteReader();
