It still get the error. Could this possible mean that the error info built by the server is in an invalid format or something like that? I have not faith that I got that part right either.

I have a simple server that creates and sets error object, and a client on another end to retrieve the error object. It always runs successfully. All are written in ATL. In the server, create and set an error object like below: ICreateErrorInfo* pcei; HRESULT hr; hr = CreateErrorInfo(&pcei); In the client side, retrieve the erro object: HRESULT hr; hr = ::CoCreateInstance(CLSID_ErrTest, NULL, CLSCTX_ALL, IID_IErrTest, hr = pErrTest->CallException(); // An exception is generated in the server. if (FAILED(hr)) if (SUCCEEDED(hr)) I never run into the similar problem before.
