[Recommended] Use vs.net to quickly develop windows Services (c #)

In many applications, windows services are required to operate databases, such
(1) Some very slow database operations, don't want to do it all at once, and want to do it slowly through regular service, such as regular database backup.
(2) Use windows Service for Host in. net Remoting

With vs.net, we can establish its windows service in a few minutes, which is very simple.

The following are the steps
1. Create a project
2. Select a Windows service from the list of available project templates
3. The designer opens in design mode.
4. Drag a Timer object from the component table in the toolbox to the design surface (Note: Make sure that Timer is used from the component list rather than from the Windows form List)

-- Note:[Recommended] [blood lessons] C # Timer controls in windows service programs
5. Set the Timer attribute. The Interval attribute is 200 milliseconds (5 database operations are performed in 1 second)
6. Then fill in the function for this service
7. double-click the Timer to generate the event "private void timerreceivelapsed (object sender, System. timers. elapsedEventArgs e ){...} "method, and then write some database operation code in it, such

Code

SqlConnection conn = new SqlConnection ("server = Wagner. 0.0.1; database = test; uid = sa; pwd = 275280 ");
SqlCommand comm =-new SqlCommand ("insert into tb1 ('20140901', 11)", conn );
Conn. Open ();
Comm. ExecuteNonQuery ();
Conn. Close ();

 

 

Appendix: it can also be written in Notepad

Code

FileStream fs = new FileStream (@ "d: \ My Sample Service.txt", FileMode. OpenOrCreate, FileAccess. Write );
StreamWriter m_streamWriter = new StreamWriter (fs );
M_streamWriter.BaseStream.Seek (0, SeekOrigin. End );
M_streamWriter.WriteLine ("My Sample Service:" + DateTime. Now. ToString () + "\ n ");
M_streamWriter.Flush ();
M_streamWriter.Close ();
Fs. Close ();

 

8. Switch the service program to the design view.
9. Right-click the design view and select "add installer"
10. Switch to the design view of the newly added ProjectInstaller.
11. Set the attributes of the serviceInstaller1 component:
1) ServiceName = My Sample Service
2) StartType = Automatic startup)
12. Set the attribute Account = LocalSystem of the serviceProcessInstaller1 component.
13. when the service is running, the Timer control is enabled, that is, timer1.Start () is added to the OnStart event ();

Protected override void OnStart (string [] args)
{
Timer1.Start ();
}

 

14. Change the path to the bin \ Debug folder of your project (if you compile in Release mode, in the bin \ Release folder)
15. Execute the command "installutil.exe mywindowsservice.exe" to register this service so that it can create an appropriate registration item. (Installutil is in the Windows Folder \ Microsoft. NET \ framework \ v1.1.4322)

 

--Installation tips:The Installation File installutil.exe cute is stored in the directory of your mywindowsservice.exejust. You can use the mouse to place your mywindowsservice.exee.onto the "“mywindowsservice.exe" icon to quickly install the installation. You do not need to enter related commands in the command console.

16. Right-click "my computer" on the desktop and select "manage" to access the computer management console.
17. In the "services" section of "services and applications", you can find that your Windows services are included in the Service list.
18. Right-click your service and choose start to start your service.
Check if the database has five more records in one second.

Note that:
If you modify this service and the path remains unchanged, you do not need to register the service again,

If the plugin changes, uninstall the installutil.exe-u parameter and reinstall the service.

In addition, the Windows Service has no interface. Do not output some information in the controlled output mode. You can only add one EventLog and write logs through writeentry.

# A color on the second floor will be mad at my machine.
Recently, I don't know what's going on. When Account = LocalSystem, the service cannot be started. It can only be set to./administrator.
Then, an EventLog is added. It cannot be written through WriteEntry.
You cannot delete Messaging. MessageQueue...

Is it true that I want to reinstall the machine?

#218.108.1. * [unregistered users] Thank you very much. The problem is finally solved. However, after I created another Windows service program, I realized that these two services could not be stored in parallel. when there was a service in the service, the system then executed the command "installutil.exe", prompting that the specified service already exists. They generate different exe file names and paths ." Or change the service name ", which is the service name. Ask again

#60.208.111, building 20. * realism [unregistered user] I used C # To write a windows Service and called the method written in other DLL. The DLL was also written in C, the result is always an error when connecting to the database (but there is no problem when calling the WEB page). The database connection information is stored in the hash table as a global change, in addition, the classes for writing connection information are serialized and I am dizzy. I don't know why.
