Run-Time Check Failure #0 - The value of ESP was not properly saved across a function call.

调用IIS管理组件时编写了下面一段代码，调用函数时提示错误：Run-Time Check Failure #0 - The value of ESP was not properly saved across a function call.  This is usually a result of calling a function declared with one calling convention with a function pointer declared with a different calling convention.

 1 std::wcout.imbue(std::locale("chs"));
 2 ::CoInitialize(NULL);
 3 
 4 CLSID clsid;
 5 HRESULT hr = ::CLSIDFromProgID(PROGID_WRITABLEADMINMANAGER, &clsid);
 6 
 7 CComPtr pAdminMgr;
 8 hr = ::CoCreateInstance(clsid, NULL, CLSCTX_LOCAL_SERVER, IID_IDispatch, reinterpret_cast(&pAdminMgr));
 9 
10 CComVariant vtServerPath(XLOG_CFGSECTION_SERVER_XPATH);
11 CComVariant vtAppHost(CFG_PATH_APPHOST);
12 CComVariant vtServerConfigSection;
13 
14 hr = pAdminMgr.PutPropertyByName(_T("CommitPath"), &vtAppHost);

国外论坛不少人也提过这个问题将Calling Convention由原来的__cdecl (/Gd)修改为__stdcall (/Gz)，其实是因为IUnknown被转换为IDispatch的问题。
