System.Runtime.InteropServices.COMException (0x00000446): Abort Received - source = 0, reason=0
在 System.RuntimeType.ForwardCallToInvokeMember(String memberName, BindingFlags flags, Object target, Int32[] aWrapperTypes, MessageData& msgData)
在 DicomObjects.DicomPrintClass.PrintImage(DicomImage Image, Boolean Raw, Boolean UseLabels)

1个回答

System.Runtime.InteropServices.COMException,说明你的控件没有正确注册,或者你的控件是32bir的,而你的.net程序是64bit的。
你可以让你的程序强制以32bit运行:

求各位大神给点意见!
本人是2012应届毕业生,网络工程专业,个人比较喜欢编程。但学校里貌似没见到网络方面的公司来招生(也许我不知道或还没来),目前看中个培训机构 教得是J2EE+3G,但是我自学的是C#(小打小闹,学得基本都是基础,做得软件等项目全是书籍来得),Java学校也有教过(jsp什么的),但我的java成绩也就是应付应付期末考试而已,我担心我去培训机构学J2EE+3G会跟不上进度或者学起来消化不了。rn 目前我考虑的是:rn 1。去培训机构学习j2EE+3G 并在他们公司实现rn 2.暂时不去培训,先把学校要考的证考了,并等待学校的安排。rn 3.还在想……rn 在此请各位路过的朋友给点意见。rnPS:大学3年多 个人感觉自己什么都不会,就会点基础 说说专业术语忽悠忽悠不懂得人O(∩_∩)O! rn 培训机构是中软国际卓越培训中心rn 语文比较差,可能有些没说清,请大家见谅。

关于网络协议的问题。。。求大神。。。
看到一本书上说:现代因特网广泛使用的数据链路层协议不使用确认和重传机制,即不要求数据链路层向上提供可靠传输服务。如果在数据链路层传输数据时出错了,出错处理由上层协议完成。这样可以提高通信效率。rnrnrn我不明白为什么这样可以提高通信效率?rnrn我认为,不管出错处理是交给那一层协议,出错处理这项工作的工作量应该没有减少(都要确认,重传),既然这样,效率怎么会提高呢?。。。。。rnrn求大神。。。。。谢谢
