如果打印不成功，则在c＃中回滚 [英] Rollback in c# if printing not successful

问题描述

大家好



在我的应用程序中，我将文本文件数据打印到打印机。

之后我发送了打印行的事务ID返回服务器，将其更新为打印。



请告诉我如何回滚打印的事务没有发生。 />
例如有时它会像纸张一样进入内部，但它会在没有打印任何内容的情况下返回，它也会用来更新数据库。



请帮我解决这个问题。

Hi all

In my application i am printing a text file data to a printer.
and after that i am sending the transaction id's of the printed lines back to the server to update them as printed.

Please tell me how to rollback the transactions of the printing didn't happens.
e.g. sometime it happens like the paper will go inside but it comes back without printing anything and it use to update the database also.

Please help me how to do this.

推荐答案

在despool期间Win32假脱机程序更新打印机和打印作业的状态打印作业。在所有其他时间，当该打印机没有解析并且没有报告状态信息时，打印机被认为是准备好并且空闲。



您可以获得打印机的状态，并根据该状态回滚您的交易，您可以提交交易。

Hi,

The status of printers and print jobs are updated by the Win32 Spooler during the despool of a print job. At all other times, when that printer is not despooling and reports no state information, the printer is considered to be ready and idle.

You get the status of the printer and on the basis of which you can rollback your transaction else, you can commit your transaction.
