Are you using some sort of entity framework ? If not, then I'd expect to read a table from the DB, iterate over it, and create a list of the type of object.

No... I am not... I want to create a collection as I already define an entity for single record, and need to know how to do it... Thank you...

This is very difficult. It requires many years of experience.
Only a c# veteran is capable of performing this feat.
Good luck.

Thanks for reply

It's not your ability to program or the fact that the question may be stupid. The problem is your ability to communicate a complete idea so someone can figure out exactly what you're talking about.

It sounds like you need to write a report. I'd suggest that you read up on this using Google.

Printing on-screen and sending to the printer are very similar. You need to use the System.Drawing namespace, in particular the Graphics class. Then hook a PrintDocument's main event (can't remember the name) and paint onto the page. Don't forget to take the page settings into account.

hello;
I have a problem using console application.I mostly use Windows application. I m using C# 2005 and Sql server2005 as part of my project.I am using 3layered architecture i have method in Business class:
public static int DataSelectionForAutoGeneratedMsg(string strTableName, out List<string> strContactNos)
Because i have to check that if a customer has his reservation booked for next day then he should be reminded for that.For that our service (which i m intended to built using console app) keep checking in the reservation table having columns(cust_id,reservation_date,service_name) .
then if the result of the query is correct i.e if it returns datatable then it has to send sms to that customer.Below is the code but i have not included the coding for sending sms here.Instead of that i have just used the Console.Writeline statement so that atlaest this par works
also i have not included the coding of internal class ConnectionString
Hope the information will be enough for u to understand
Code:
using System;
using System.Collections.Generic;
using System.Text;
using System.Data;
using System.Collections;
using System.Data.SqlClient;
using HRCF.BL;// adding Business logic
using HRCF.DB;//adding database
using System.ComponentModel;
namespace ConsoleApp_service
{
public class services
{
//private CHRCFDB m_objCHRCFDB = null;
public services()
{
//m_objCHRCFDB = new CHRCFDB();
}
static void Main(string[] args)
{
Console.WriteLine("Reading this line");
//dont kno wheather th efollowing line of code is correct or not.It gives no error but no output as well!!
string result = Checkingreservation("reservation", out dtTableRecords_out);
}
public static string CheckingReservation(string strTableName, out DataTable dtTableRecords_out)
{
string strQueryString = "";
SqlCommand objSqlCommand = null;
SqlConnection objSqlConnection = null;
DataSet objDataSet = null;
SqlDataAdapter objDataAdapter = null;
// checking from the current date
string ritenow = Convert.ToString(System.DateTime.Now);
try
{
objDataSet = new DataSet();
objDataAdapter = new SqlDataAdapter();
objSqlConnection = new SqlConnection(ConnectionString.GetSQLConnectionString());
strQueryString = "select cust_id,ser_name from reservation where date = " + ritenow;
objSqlCommand = new SqlCommand(strQueryString, objSqlConnection);
objDataAdapter.SelectCommand = objSqlCommand;
objSqlConnection.Open();
objDataSet.Clear();
objDataAdapter.Fill(objDataSet);
objSqlConnection.Close();
dtTableRecords_out = objDataSet.Tables[0];
if (dtTableRecords_out != null)
{
Console.WriteLine("Service is reserved for today");
}
else
{
Console.WriteLine("No reservation for today");
}
}
finally
{
if (objSqlConnection.State == ConnectionState.Open)
{
objSqlConnection.Close();
}
}
return strQueryString;
}
}
}
I am unable to find any error.When i debug it then nothing happens no black window instead of it an empty form appears.

Hi,
Did you set the output type in project properties to Console Application? It's useful to have Console.Readline() as the final statement in the main method to prevent the window closing before you have read the contents.

First of all make sure that you have created project by selecting proper project type and secondly put Console.Read(); statement at very end of your main method to put a pasue in execution.

Hi ,
I created a JOB Scheduling for Automatic DB backup in SQL server Agent using Microsoft.Sqlserver.Smo.
I followed all the step mentioned in msdn for creating job programmatically.
I used C# code for this.
Here are the step I used.
Create JOB object , Create Job Step then Job Scheduler.
Job is created everything is created successfully but when I see this job in Job Activity monitor it's next run date is coming null and Runnable option is coming No.Because of this my scheduler is not executing.
If I create a job manually through wizard the next date is populating and runnable is yes ad it is working fine. I did comparasion both of the jobs but didn't get any difference.
Can any one please help me to figure out this as I waste complete one day for this
Thanks in Advance
