calling function

[June Lee]

how can I call the put_ConnectionString correctly?

when I do the following I got compile error
BSTR bstr = "aaa";
hr.put_ConnectionString(bstr);

HRESULT CEPGLibApp::LoadXMLData(LPCTSTR tszXMLFileName)
{
HRESULT hr = S_OK;

CComPtr<ISQLXMLBulkLoadpIXMLBulkLoad;
hr = CoCreateInstance(CLSID_SQLXMLBulkLoad3, NULL,
CLSCTX_INPROC_SERVER, IID_ISQLXMLBulkLoad, (void **)&pIXMLBulkLoad);

if (SUCCEEDED(hr)) {
BSTR bstr = "aaa";
hr.put_ConnectionString(bstr);
}

if (SUCCEEDED(hr)) {
}

if (SUCCEEDED(hr)) {
}

return hr;
}
