向下投票最爱





我正在使用visual studio 2012.我正在尝试通过桌面与生物识别考勤设备进行交互通过IP地址申请。我将必要的dll和ocx文件添加到项目的参考文件夹中。我很容易创建'SB100PCLib'的对象，但是当我尝试执行它的函数时，我得到了这个运行时错误



灾难性故障（HRESULT异常：0x8000FFFF） （E_UNEXPECTED））



由于我是第三方dll的新手，是否有任何额外的步骤要执行？如何摆脱错误？

I am using visual studio 2012. I am trying to interact with a biometric attendance device through a desktop application via ip address. I added the necessary dll and ocx files to the reference folder of the project. I created the object of 'SB100PCLib' quite easily, but when I try to execute its functions, I get this run time error

Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED))

As I am quite new dealing with third party dll, is there any extra step to perform? How to get rid of the error?
