（注意：已经略去无关代码）

初始化：

CoInitialize(NULL);
 _ConnectionPtr pConn(__uuidof(Connection));
 //_RecordsetPtr pRst(__uuidof(Recordset));
 pConn->ConnectionString="Provider=SQLOLEDB.1;Password=xxx;Persist Security Info=True; User ID=sa;Initial Catalog=ArticleCollection";
 pConn->Open("","","",adConnectUnspecified);

调用

 _variant_t RecordsAffected;

pConn->Execute(sqlInsert,&RecordsAffected,-1);
  释放：

pConn->Close();
 pConn->Release();
 CoUninitialize();

异常出现在文件 comip.h中红色位置的函数体内

private:
    // The Interface.
    //
    Interface* m_pInterface;

    // Releases only if the interface is not null.
    // The interface is not set to NULL.
    //
    void _Release() throw()
    {
        if (m_pInterface != NULL) {
            m_pInterface->Release();
        }
    }
