我调用雷组件进行下载！怎么监测它是否完成！有个GetTaskInfo()应该写到监测函数里！但不知怎么写监测模块？在哪调用？
void CMp3TideDlg::OnBnClickedButton4()
{//单击下载
HRESULT hRes = ::CoInitialize(NULL);
IAgent *pAgent = NULL;
hRes = CoCreateInstance(__uuidof(Agent), NULL, CLSCTX_INPROC_SERVER, __uuidof(IAgent), (void**)&pAgent);
pAgent->AddTask(_T("http:://*****"),
_T(""),
_T(""), _T(""), _T(""),
1, 0, -1);
}
}
pAgent->CommitTasks();
}
最好写段代码参考

检测模块用try来写，用catch捕获相应的错误。再用throw抛出错误
try {
// code that could throw an exception
}
[ catch (exception-declaration) {
// code that executes when exception-declaration is thrown
// in the try block
}
[catch (exception-declaration) {
// code that handles another exception type
} ] . . . ]
// The following syntax shows a throw expression:
throw [expression]
