c#.netでタイマー付きのWindowsサービスを作成しました。Visual Studioでプロジェクトをデバッグ/ビルドしている間は正常に動作しますが、インストール後に操作は実行されません。
この背後にある理由は何でしょうか?
コード:
public partial class Service1 : ServiceBase
{
FileStream fs;
StreamWriter m_streamWriter;
Timer tm = new Timer();
public Service1()
{
InitializeComponent();
this.ServiceName = "timerservice";
tm.Interval = 2000;
tm.Tick += new EventHandler(PerformOperations);
tm.Start();
fs = new FileStream(@"c:\mcWindowsService.txt", FileMode.OpenOrCreate, FileAccess.Write);
m_streamWriter = new StreamWriter(fs);
m_streamWriter.BaseStream.Seek(0, SeekOrigin.End);
}
private void PerformOperations(object sener, EventArgs e)
{
//StreamWriter swr = new StreamWriter("c:\\test_from_database.txt",true);
try
{
OdbcConnection con = new OdbcConnection("DSN=liquor_data");
OdbcDataAdapter adp = new OdbcDataAdapter("", con);
DataSet ds = new DataSet();
string sql = "select * from item_group";
adp.SelectCommand.CommandText = sql;
adp.Fill(ds, "item_group");
foreach (DataRow dr in ds.Tables["item_group"].Rows)
{
// swr.Write(dr["group_name"].ToString() + "\t\t" + DateTime.Now.TimeOfDay.ToString() + "\n");
//Console.WriteLine(dr["group_name"].ToString() + "\t\t" + DateTime.Now.TimeOfDay.ToString() + "\n");
m_streamWriter.WriteLine(dr["group_name"].ToString() + "\t\t" + DateTime.Now.TimeOfDay.ToString() + "\n");
}
m_streamWriter.Flush();
}
catch (Exception ex)
{
// swr.Write("Error :"+ ex.Message + "\t\t" + DateTime.Now.TimeOfDay.ToString() + "\n"); }
}
}
}
