Can anyone post a working code example of a Windows Service? I tried using the code in the article and had to play with it a bit to get it to compile. I then added an installer project and eventually installed the service in Windows. My service starts then stops and I get the message that "your service started then stopped..."
Here is what I have:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Diagnostics;
using System.Linq;
using System.ServiceProcess;
using System.Text;
using System.Data.SqlClient;
using System.Xml;
using System.IO;
namespace svcbroker
{
public partial class Service1 : ServiceBase
{
private bool m_Terminate = false;
private string LogFolder = "c:\\svcbroker\\LogFolder\\";
private string ArchiveFolder = "c:\\svcbroker\\ArchiveFolder\\";
public Service1()
{
InitializeComponent();
}
protected override void OnStart(string[] args)
{
using (SqlConnection Conn = new SqlConnection("Data Source=(local);Initial Catalog=ServiceBroker;Integrated Security=SSPI"))
{
Conn.Open();
using (SqlCommand Cmd = Conn.CreateCommand())
{
Cmd.CommandText = "ProcessLogQueue";
Cmd.CommandType = System.Data.CommandType.StoredProcedure;
Cmd.CommandTimeout = 0; // no timeout
while (!this.m_Terminate) // looping until the service is stopped
{
string Response = Cmd.ExecuteScalar().ToString(); // execute the command
if (Response.Length > 0)
{
XmlDocument Doc = new XmlDocument();
Doc.LoadXml(Response);
XmlNode RootNode = Doc.SelectSingleNode("LOG");
XmlNode RowNode = RootNode.SelectSingleNode("Row");
string ProcessName = RowNode.SelectSingleNode("ProcessName").InnerText;
string MachineName = RowNode.SelectSingleNode("MachineName").InnerText;
string MachineFolder = Path.Combine(this.LogFolder, MachineName);
if (!Directory.Exists(MachineFolder))
{
try
{
Directory.CreateDirectory(MachineFolder);
}
catch (Exception Ex)
{
// log the failure to a logfile for the Windows Service
return;
}
}
// create the name of the log file
string FileName = Path.Combine(MachineFolder, ProcessName + ".log");
try
{
this.CheckLog(MachineName, FileName); // does the log file nee to be archived?
}
catch (Exception Ex)
{
// log the failure to a logfile for the Windows Service
return;
}
try
{
using (StreamWriter SW = new StreamWriter(FileName, true))
{
SW.WriteLine(string.Format("{0} {1}", RowNode.SelectSingleNode("LogTime").InnerText,
RowNode.SelectSingleNode("ProcessMessage").InnerText));
}
}
catch (SqlException Ex)
{
// log the failure to a logfile for the Windows Service and quit
}
catch (System.Threading.ThreadAbortException)
{
// we have been ordered to quit
}
catch (Exception Ex)
{
// log the failure to a logfile for the Windows Service and quit
}
}
}
}
}
}
private void CheckLog ( string MachineName, string FileName )
{
FileInfo FI = new FileInfo ( FileName );
if ( FI.Exists )
{
DateTime Today = Convert.ToDateTime ( DateTime.Now.ToShortDateString () );
if ( FI.LastWriteTime < Today )
{
string ArchiveFileName = Path.GetFileName ( FileName ).Replace ( ".log", FI.LastWriteTime.ToString ( "yyyyMMdd" ) + ".log" );
string MachineFolder = Path.Combine ( this.ArchiveFolder, MachineName );
if ( !Directory.Exists ( MachineFolder ) )
{
Directory.CreateDirectory ( MachineFolder );
}
FI.MoveTo ( Path.Combine ( MachineFolder, ArchiveFileName ) );
}
}
}
protected override void OnStop()
{
}
}
}
