[询问] C#.net中的TAPI3 [英] [ask] TAPI3 in C#.net

问题描述

我尝试使用TAPI3接口开发应用程序，但是在c#.net中运行C ++代码时遇到了一些问题:

I try to develop application using TAPI3 interface, but I got some problem when run C++ code in c#.net:

ITStreamControl * pStreamControl;
HRESULT hr = pBasicCall->QueryInterface(
        IID_ITStreamControl,
        (void **) &pStreamControl
        );

I used this : 
ITStreamControl pstream_control;
                                    
pstream_control=(ITStreamControl) call_control;

但我收到此消息指定的演员表无效".
