how to update a table in c# using oledb parameters?
- by sameer
I am having a table which has three fields, namely LM_code,M_Name,Desc. LC_code is a autogenerated string Id, keeping this i am updating M_Name and Desc. I used normal update command, the value is passing in runtime but the fields are not getting updated. I hope using oledb parameters the fileds can be updated. 
Any help will be appreciated...
Here is my code. 
public void Modify()
        {
            String query = "Update Master_Accounts set (M_Name='" + M_Name + "',Desc='" + Desc + "') where LM_code='" + LM_code + "'";
            DataManager.RunExecuteNonQuery(ConnectionString.Constr, query);
        }
In DataManager Class i am executing the query string.
public static void RunExecuteNonQuery(string Constr, string query)
        {
        OleDbConnection myConnection = new OleDbConnection(Constr);
        try
        {
            myConnection.Open();
            OleDbCommand myCommand = new OleDbCommand(query, myConnection);
            myCommand.ExecuteNonQuery();
        }
        catch (Exception ex)
        {
            string Message = ex.Message;
            throw ex;
        }
        finally
        {
            if (myConnection.State == ConnectionState.Open)
                myConnection.Close();
        }
    }
private void toolstModify_Click_1(object sender, EventArgs e)
        {
            txtamcode.Enabled = true;
            jewellery.LM_code = txtamcode.Text;
            jewellery.M_Name = txtaccname.Text;
            jewellery.Desc = txtdesc.Text;
            jewellery.Modify();
            MessageBox.Show("Data Updated Succesfully");
    }
