Message: <blockquote data-quote="Andy Nguyen" data-source="post: 12188" data-attributes="member: 1">I wrote my first window service in C# today. It's so cool.There are plenty of guide online but most are confusing, outdated so it feels great when it's finally working.The window service will run in the background. I need to write this so it will copy all the tools code I wrote in my C:\ and put them into a network drive. It will do it once a day when I leave work. You never know what will happen with your code, machine, etc so having latest code will come back and save my life sometimes.Some of the problem is .NET don't have a copy directory method. It only has copy file so I have to add a copy directory recursively class. I also have to add a timer and set it to start the service every 24 hours. It will copy and overwrite all my code to a shared drive. It will also write to a log file with timestamp when it start/stop.Apparently, I can write some code so it can call Winrar program, zip it to a zip file and dump that file instead of copy the whole dir. I'll do it tomorrow.Having a window service is so great. I can add many tasks to it so it can update the database, save the code, email me if there is any error. Once I set this up, I don't have to remember anymore. This will come in handy in the future when we need to run something overnight.I love C# ![code]using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.IO;using System.IO.Compression;using System.Diagnostics;using System.ServiceProcess;using System.Text;using System.Threading;//window servicenamespace wsAndy{public partial class wsSaveProject : ServiceBase{private Timer stateTimer;private TimerCallback timerDelegate;public wsSaveProject(){InitializeComponent();}protected override void OnStart(string[] args){//TODO: Add code here to start your service.timerDelegate = new TimerCallback(OnTick);stateTimer = new Timer(timerDelegate, null, 0, 86400000); // 1000ms = 1 secs}protected override void OnStop(){// TODO: Add code here to perform any tear-down necessary to stop your service.stateTimer.Dispose();FileStream fs = new FileStream(@"\\Backup\wsBackupCodeLog.txt",FileMode.OpenOrCreate, FileAccess.Write);StreamWriter m_streamWriter = new StreamWriter(fs);m_streamWriter.BaseStream.Seek(0, SeekOrigin.End);m_streamWriter.WriteLine("Windows service wsSP stopped at \n" + DateTime.Now.ToString());m_streamWriter.Flush();m_streamWriter.Close();}private void OnTick(object stateObject){// Don't let service crashtry{// Do your stuff hereDirectoryInfo src2005 = new DirectoryInfo(@"c:\Documents and Settings\My Documents\Visual Studio 2005");DirectoryInfo dsn2005 = new DirectoryInfo(@"\\backups\VS2005");FileStream fs = new FileStream(@"\\backups\wsBackupCodeLog.txt",FileMode.OpenOrCreate, FileAccess.Write);StreamWriter m_streamWriter = new StreamWriter(fs);m_streamWriter.BaseStream.Seek(0, SeekOrigin.End);m_streamWriter.WriteLine("VS2005/8 last copied at \n" + DateTime.Now.ToString());m_streamWriter.Flush();m_streamWriter.Close();copyDirectory(src2005, dsn2005, true);}catch (Exception ex){try{this.EventLog.WriteEntry(ex.Message, EventLogEntryType.Error);}catch (Exception exx){//Bad luck, handle it differently or rethrow original exception}}}public static void copyDirectory(DirectoryInfo srcPath, DirectoryInfo destPath, bool recursive){if (!destPath.Exists)destPath.Create();// copy filesforeach (FileInfo fi in srcPath.GetFiles()){fi.CopyTo(Path.Combine(destPath.FullName, fi.Name), true);}// copy directoriesif (recursive){foreach (DirectoryInfo di in srcPath.GetDirectories()){copyDirectory(di, new DirectoryInfo(Path.Combine(destPath.FullName, di.Name)), recursive);}}}}}[/code]</blockquote>
