Example on Windows Service Wothout Setup

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...

What Is Delegate with a simple example

aIntroduction
This article is an attempt to explain a delegate with a simple example. Delegates are similar to function pointers in C++. For simple understanding delegates can be defiend as methods that are used to call other method. Only condition to call

another method from a delegate is that the signature of the calling methods and delegates should match.
Follw This Step
Delegates should have the same signature as the methods to be called by them.
i.e. Say that we are calling an addNumbers method which returns an integer by taking (int, int) as input. Then our

delegate also must have been declared with the same signature.
Delegate Declaration:
public delegate int simpleDelegate (int a, int b);

Method:
public int addNumber(int a, int b)
Step For Create And Cal A Delegate
--Create a delegate. A delegate can be created with the delegate keyword, followed by it's return type, then name of the

delegate with the input patameters.

public delegate int simpleDelegate (int a, int b);

--Define the methods which are having similar signature as the delegate.

public int mulNumber(int a, int b)
public int addNumber(int a, int b)

--Now we are all set to use the delegates. Just instatiate the class and call the methods using the delegates.
Code Use

class clsDelegate
{
public delegate int simpleDelegate (int a, int b);
public int addNumber(int a, int b)
{
return (a+b);
}
public int mulNumber(int a, int b)
{
return (a*b);
}
static void Main(string[] args)
{
clsDelegate RAPatel = new clsDelegate();
simpleDelegate addDelegate = new simpleDelegate(RAPatel.addNumber);
simpleDelegate mulDelegate = new simpleDelegate(RAPatel.mulNumber);
int addAns = addDelegate(10,12);
int mulAns = mulDelegate(10,10);
Console.WriteLine("Result by calling the addNum method using a delegate: {0}",addAns);
Console.WriteLine("Result by calling the mulNum method using a delegate: {0}",mulAns);
Console.Read();
}
}

     Lists are considered generics and constructed types. You need to use < and > in the List declaration.
     List <>  is Following Step
1)    Create Class for List

public class AddROSublet     {         string _Id;         string _FaultId;         string _VendorName;         string _VendorId;                      public string VendorName         {             get             {                 return _VendorName;             }             set             {                 _VendorName = value;                             }         }         public string VendorId         {             get             {                 return _VendorId;             }             set             {                 _VendorId = value;            }         }             }

2) Create object For List and Add Value in List

public List<Test> lParts = new List<Test>(); lParts.Add(new Test() {        Id = 1,     FId = “9999”,     Name =”Tejas”,     vId = 1003     }); lParts.Add(new Test() {        Id = “2”,     FId = “9999”,     Name =”Dhaval”,     vId = 1002     }); lParts.Add(new Test() {        Id = “3”,     FId = “9999”,     Name =”Amit”,     vId = 1001
