用水晶报表打印如何控制暂停和继续?

[yj01263431]

private void PrintOrders(string orderid) { DataTable dtPrint = bus.GetOrderDetailsInfo(orderid); dtPrint.TableName = "dtOrderDetailsInfo"; string pathRpt = Application.StartupPath.Replace("\\bin\\Debug", "") + @"\crGoodsReport.rpt"; ReportDocument repostDoc = new ReportDocument(); repostDoc.Load(pathRpt);// 加载打印模板文件 repostDoc.SetDataSource(dtPrint);// 设置数据源 repostDoc.PrintOptions.PrinterName = bus.GetAttrValueByUserName("选择打印机", Business.userName); // 设置打印机名称 repostDoc.PrintOptions.PaperSize = CrystalDecisions.Shared.PaperSize.Paper10x14;// 设置打印纸张样式 repostDoc.PrintOptions.PaperOrientation = CrystalDecisions.Shared.PaperOrientation.DefaultPaperOrientation;//纸张方向 repostDoc.PrintToPrinter(1, true, 1, 10); } repostDoc.PrintToPrinter(1, true, 1, 10); 执行这一句的时候就直接打印了，怎么暂停呢？ 用线程暂停好像控制不了吧

repostDoc.PrintToPrinter(1, true, 1, 10)

这行代码是发送请求给打印机，命令发送后打印与否和报表就没关系了。

问题是怎么控制暂停呢？

随便问一下 repostDoc.PrintToPrinter(1, true, 1, 2) 改为 repostDoc.PrintToPrinter(1, true, 1, 1) repostDoc.PrintToPrinter(1, true, 2, 2) 打印出来的效果是否一样？ 因为我还要加个进度条

这不是水晶报表能控制到的了吧

任务发送给打印机，暂停或者继续和水晶报表没神马关系

打印的时候如何获取打印Jobid 呢 ，就差这个了 有了JobID我就可以暂停了 public static bool PauseOrResumePrintJob(string printerName, int printJobID, string type) { bool isActionPerformed = false; string searchQuery = "SELECT * FROM Win32_PrintJob"; ManagementObjectSearcher searchPrintJobs = new ManagementObjectSearcher(searchQuery); ManagementObjectCollection prntJobCollection = searchPrintJobs.Get(); foreach (ManagementObject prntJob in prntJobCollection) { System.String jobName = prntJob.Properties["Name"].Value.ToString(); //Job name would be of the format [Printer name], [Job ID] char[] splitArr = new char[1]; splitArr[0] = Convert.ToChar(","); string prnterName = jobName.Split(splitArr)[0]; int prntJobID = Convert.ToInt32(jobName.Split(splitArr)[1]); string documentName = prntJob.Properties["Document"].Value.ToString(); if (String.Compare(prnterName, printerName, true) == 0) { if (prntJobID == printJobID) { if (type == "Pause") prntJob.InvokeMethod("Pause", null); else prntJob.InvokeMethod("Resume", null); isActionPerformed = true; break; } } } return isActionPerformed; }
