Example on Windows Service

Hi Friends,in this post i would like to explain windows service for displaying message box for every 3 seconds.

Step 1:

* Open windows service project with projectName WinService1
* Goto ToolBox-->General-->Right Click-->Select choose items-->Select Timer(Systems.Timers)
* Project-->AddReference-->System.Windows.Forms(Message Box is a part of above reference).
* Place a Timer(System.Timers) with interval-3000 & enabled-false.

Code:

{//timer1_Elapsed event.
System.Windows.Forms.MessageBox.Show("This message from Windows Service.");
}

Code for OnStart() event
{
timer1.Enabled=true;
}

Code for OnStop() event
{
timer1.Enabled=false;
}





Step 2:

* Open service1.cs[design]
Right Click
Add installer(Select).
Then 2 controls will be added to the form.
1)ServiceProcessInstaller-->Choose properties-->Account=LocalSystem.
2)ServiceInstaller-->Properties-->ServiceName=MessageBoxDisplay

* Build the project(Build-->Select Build solution)

Note:
* WinService1.exe is created under:
D:\WinService1\bin\debug folder with a service name called as "MessageBoxDisplay"

Step 3:

* open .Net Command prompt.
Start-->Programs-->MSVisualStudio2005-->VSTools-->.Net Command Prompt.
>installutil -i D:\WinService1\bin\debug\WinService1.exe (press enter)
>....
>....
>....
>transaction install has completed.

Step 4:

* Open service(Start-->run-->services.msc)
* MessageBoxDisplay-->RightClick-->Properties-->Logon-->Check "interact with desktop" checkBox-->OK
(Only service contains MessageBox otherwise above step is not required).
* MessageBoxDisplay-->rightClick-->Start.

Then service will be started & MessageBox with message(This message from Windows Service.) will be displayed for every 3 seconds.


Thank You...

Displaying Festival Names on Calendar control in ASP.Net

Hi Friends,In this article i would like to explain how to display Festival Names on Calender control in ASP.Net.

* For this i took 1 Calendar control on to the page.

* I created a table with name(Holidays) in SQL Server 2005 & fields are HolidayName,HolidayDate.

* Please find the below table once :

* Then find the code for Calender_DayRender event : 
Source Code : 

Default.aspx.cs :

using System;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using System.Data.SqlClient;
public partial class _Default : System.Web.UI.Page
{
SqlConnection con;
protected void Page_Load(object sender, EventArgs e)
{
 con = new SqlConnection(ConfigurationManager.ConnectionStrings["DotnetGuruConnectionString"].ConnectionString);
}
protected void Calendar1_DayRender(object sender, DayRenderEventArgs e)
{
 CalendarDay day = (CalendarDay)e.Day;
 SqlCommand cmd = new SqlCommand("select HolidayName,HolidayDate from Holidays", con);
 con.Open();
 SqlDataReader dr = cmd.ExecuteReader();

 while (dr.Read())
 {
     if (day.Date.ToString() == dr["HolidayDate"].ToString())
     {
         TableCell cell = (TableCell)e.Cell;
         string s1 = dr["HolidayName"].ToString();
         if (s1 != null)
         {
             cell.BackColor = System.Drawing.Color.LightGray;
             cell.Controls.Add(new LiteralControl("
" + s1));
         }

     }

 }
 con.Close();
}
}

Design View : 

Default.aspx :
using System;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using System.Data.SqlClient;
public partial class _Default : System.Web.UI.Page
{
SqlConnection con;
protected void Page_Load(object sender, EventArgs e)
{
 con = new SqlConnection(ConfigurationManager.ConnectionStrings["DotnetGuruConnectionString"].ConnectionString);
}
protected void Calendar1_DayRender(object sender, DayRenderEventArgs e)
{
 CalendarDay day = (CalendarDay)e.Day;
 SqlCommand cmd = new SqlCommand("select HolidayName,HolidayDate from Holidays", con);
 con.Open();
 SqlDataReader dr = cmd.ExecuteReader();

 while (dr.Read())
 {
     if (day.Date.ToString() == dr["HolidayDate"].ToString())
     {
         TableCell cell = (TableCell)e.Cell;
         string s1 = dr["HolidayName"].ToString();
         if (s1 != null)
         {
             cell.BackColor = System.Drawing.Color.LightGray;
             cell.Controls.Add(new LiteralControl("
" + s1));
         }

     }

 }
 con.Close();
}
}

* Then finally Build(F6) your application & run the application by pressing(F5) button.

* Your out put will looks like as below : Thank You...
