5.服务管理界面主要代码
1）初始化

private void FormMain_Load(object sender, EventArgs e) { try { m_Data = new DataSet(); m_SettingFile = System.AppDomain.CurrentDomain.SetupInformation.ApplicationBase + "TaskSettings.xml"; if (!File.Exists(m_SettingFile)) MakeTaskSettings(m_SettingFile); m_Data.ReadXml(m_SettingFile); if (m_Data == null || m_Data.Tables.Count < 1) { throw new Exception("No task settings found."); } this.dataGridView1.DataSource = m_Data; this.dataGridView1.DataMember = m_Data.Tables[0].TableName; if (m_Data.Tables[0].Rows.Count > 0) dataGridView1.CurrentCell = dataGridView1.Rows[0].Cells[0]; } catch (Exception ex) { MessageBox.Show(ex.Message); } try { m_Service = new ServiceController("DamsonwarePrintServiceZpl"); if (m_Service.Status.Equals(ServiceControllerStatus.Running)) { buttonStop.Enabled = true; buttonStart.Enabled = false; } else { buttonStop.Enabled = false; buttonStart.Enabled = true; } } catch(Exception ee) { buttonStart.Enabled = false; buttonStop.Enabled = false; MessageBox.Show("Checking Service status have error: " + ee.Message); } } |
2）保存代码

3)启动服务
