                        sqlConnection2.Close();


                        SqlConnection NewConn = new SqlConnection();
                        NewConn.ConnectionString=BizLog.Conn.ConnString();

                        NewConn.Close();

                        IDbCommand cmd1 = this.sqlConnection1.CreateCommand();
                        IDbCommand cmd2 = this.sqlConnection2.CreateCommand();

                        cmd1.CommandText = "SELECT * FROM Products";
                        cmd2.CommandText = "Select * From VIEW1";

                        IDbCommand CmdGetTotalByCode=NewConn.CreateCommand();
                        IDbCommand CmdgetHatByCode = NewConn.CreateCommand();


                        CmdGetTotalByCode.CommandText="SELECT SUM(Kamot) AS ParitTotal FROM Actions WHERE (CodeParit = @CA)";
                        SqlParameter parm = new SqlParameter("@CA",SqlDbType.VarChar,50,"CodeParit");
                        parm.Direction=ParameterDirection.Input;
                        CmdGetTotalByCode.Parameters.Add(parm);


                        CmdgetHatByCode.CommandText="SELECT ProMinimom FROM View1 WHERE (ProKey = @CA)";
                        SqlParameter parm1 = new SqlParameter("@CA",SqlDbType.VarChar,50,"ParitNum");
                        parm1.Direction=ParameterDirection.Input;
                        CmdgetHatByCode.Parameters.Add(parm1);

                        sqlConnection1.Open();
                        sqlConnection2.Open();
                        IDataReader reader = cmd1.ExecuteReader();
                        IDataReader reader1 = cmd2.ExecuteReader();

                        while (reader.Read())
                        {
                              string ProKey = reader["ProKey"].ToString();
                              while(reader1.Read())
                              {
                                    string Pkey=reader1["ProKey"].ToString();
                                    if (ProKey.ToString()==Pkey.ToString())
                                    {
                                          string Degem=reader["ProKey"].ToString();

                                          parm.Value=Degem.ToString();
                                          parm1.Value=Degem.ToString();

                                          NewConn.Open();
                                          int t=Int32.Parse(CmdGetTotalByCode.ExecuteScalar().ToString());
                                          int h=Int32.Parse(CmdgetHatByCode.ExecuteScalar().ToString());
                                          NewConn.Close();
                                          if (h>t)
                                          {


                                                listBox1.Items.Add("ProKey" + Degem.ToString() + " " + "U need to order moreי");


                                          }
                                    }
                              }

                        }
                        reader.Close();
                        reader1.Close();

                        sqlConnection1.Close();
                        sqlConnection2.Close();

but its dosent work well

Agarici

you should make the sql server return only what you need. that is a table that has only products for each you need to make an alert.

you can do this by a simple select like this (i dont know the exact structure of you database so names are more like a guess):

select Products.*
from Products inner join ActionTable
on Products.ID == ActionTable.ProductID
where Products.MinStock < ActionTable.ProductQuantity

then parse the returned DataTable and do your alert thing
