WinForm中的简单打印
最近工作很是郁闷,有做WEB又要改桌面程序,要求之前基于DevExpress报表打印改成 DataGridView呈现数据 ,配置30分钟提醒用户打印,我发现我是越来越懒了,主要是情绪不好,什么问题 第一反应肯定谷歌之然后自己封装下,无暇思考,万能的谷歌啊

调用即可

private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e) { string[] foot = { }; Printer p = new Printer(this.dgvWarehouseView, printDocument1, foot); p.Print(e.Graphics); } if (DialogResult.OK == MessageBox.Show("请确认需要打印吗?", "提示", MessageBoxButtons.OKCancel, MessageBoxIcon.Information)) { if (this.printDialog1.ShowDialog() == DialogResult.OK) { this.printDocument1.Print(); } }
订阅提醒打印事件,时间我用Web的缓存做了
public delegate void SettingTimeNotifyDelegateHandler(string time); public event SettingTimeNotifyDelegateHandler EventSettingTimeNotifyDelegateHandler; if (!string.IsNullOrEmpty(this.numTime.Value.ToString())) { if (EventSettingTimeNotifyDelegateHandler != null) { EventSettingTimeNotifyDelegateHandler(this.numTime.Value.ToString()); this.Close(); } } SetTime st = new SetTime(); st.EventSettingTimeNotifyDelegateHandler += (time) => { _time = Convert.ToInt32(time) * 60; CacheHelper.SetCacheData("SetTimeNoify", "SetTimeNoify", _time); //this.axWindowsMediaPlayer1.URL = Application.StartupPath + "\\流水.wav"; //this.axWindowsMediaPlayer1.Ctlcontrols.play(); }; st.ShowDialog(); if (!CacheHelper.IsCacheExist("SetTimeNoify")) { CacheHelper.SetCacheData("SetTimeNoify", "SetTimeNoify", _time); this.axWindowsMediaPlayer1.URL = Application.StartupPath + "\\流水.wav"; this.axWindowsMediaPlayer1.Ctlcontrols.play(); //if (MessageBox.Show("系统提醒您打印数据?", "提醒", MessageBoxButtons.OKCancel, MessageBoxIcon.Information) == DialogResult.OK) //{ // this.axWindowsMediaPlayer1.Ctlcontrols.stop(); //} }
