当我使用Crystal Reports从Vb.Net打印时，文档状态正在等待...... [英] When I Print From Vb.Net Using Crystal Reports, Document Status Is Pending ...

问题描述

您好，

我在使用CrystalReports从VB.NET打印时遇到问题，我直接打印到打印机，我的代码是：

Hello,
I have a problem in printing from VB.NET using CrystalReports, i print directly to the printer, my code is:

Dim crtableLogoninfos As New TableLogOnInfos
 Dim crtableLogoninfo As New TableLogOnInfo
 Dim crConnectionInfo As New ConnectionInfo
 Dim CrTables As Tables
 With crConnectionInfo
     .ServerName = myCon.ServerName
     .DatabaseName = myCon.DBName
     .UserID = "sa"
     .Password = ""
 End With
 Dim iRpt As New rptBarcode
 iRpt.Load()
 Dim CrTable As Table
 CrTables = iRpt.Database.Tables
 For Each CrTable In CrTables
     crtableLogoninfo = CrTable.LogOnInfo
     crtableLogoninfo.ConnectionInfo = crConnectionInfo
     CrTable.ApplyLogOnInfo(crtableLogoninfo)
 Next
 iRpt.Refresh()
 Dim iPrd As New System.Drawing.Printing.PrintDocument
 iRpt.PrintOptions.PrinterName = iPrd.PrinterSettings.PrinterName
 iRpt.PrintToPrinter(1, False, 0, 0)
 iRpt.Dispose()
 iRpt.Close()

但是当我运行此代码时，打印机文档将进入打印队列，其状态为待定但未实际打印。请注意，我尝试从word，excel和打印机等其他软件进行打印。

我的代码是真的吗？什么是可能的问题。

But when i run this code the printer document go to the printing queue and its status is Pending but not physically printed. Note that i tried to print from other softwares like word, excel and the printer works properly.
Is my code true? And what is the possible problem.

推荐答案

看起来报表查看器没有将ENDDOCPRINT发送到打印假脱机程序 - 但是根据文档 [ ^ ]您的参数是正确的。



然而，我会在Dispose（）之前移动Close（）

It looks like the report viewer is not sending the ENDDOCPRINT to the print spooler - but according to the documentation [^] your parameters are correct.

I would, however, move Close() before Dispose()
