检查扫描实施，扫描仪 [英] Cheque Scanning Implementation,Scanner

问题描述

有没有人在Windows应用程序中实施Magtek Excella设备dll？



我试图使用MTMICRProcessCheck（）方法一次处理n次检查。



在我的安装选项中，我将DocFeed保持为AUTOFEED仍需要两次检查处理而不是n次检查。

我的结果是我得到的XML字符串只有第一次扫描检查的信息。



如果有人实现了同样的，善意的帮助！

解决方案

这是我的代码，供参考

Hi,

Have anyone worked in implementation of Magtek Excella device dll in Windows application ?

I am trying to Process n number of cheques at a time using MTMICRProcessCheck() Method.

In my Setup options i have kept DocFeed as AUTOFEED still it takes two cheques for processing and not n number of cheques.
As my result i get a XML string having info for 1st scanned cheque only.

If someone has implemented the same,kindly help !

Here is my code,For reference
