Use of new operator -compiled error C2661: 'CObject::operator new' : no overloaded function takes 4 arguments (Multiple Inheritance)

I have the below class in header file

class CodeListSqlGenerator : public ICodeListSqlGenerator,public CDialog


{
    ........
public:
CodeListSqlGenerator(IIntelligentCodeListUpgraderParameter *i_intelligent_codelist_upgrader_parameter);
}

When I use a new operator in .cpp file to create an object of type CodeListSqlGenerator

ICodeListSqlGenerator *CreateCodeListSqlGeneratorInterface(IIntelligentCodeListUpgraderParameter *i_intelligent_codelist_upgrader_parameter)
{
ICodeListSqlGenerator *i_codelist_sql_generator = new CodeListSqlGenerator(i_intelligent_codelist_upgrader_parameter);
return i_codelist_sql_generator;
}

I'm get getting the below when compiled error C2661: 'CObject::operator new' : no overloaded function takes 4 arguments How do I rectify this error? Thanks in advance -Athreya

DEBUG_NEW macro has to be change,. check whether you have included preprocessor #undef new, Try to write the #undef new before the new keyword

It looks like you are trying to create an ICodeListSqlGenerator object using the CodeListSqlGenerator constructor. This cannot be done, as ICodeListSqlGenerator already has its own constructor. However, a CodeListSqlGenerator object IS A ICodeListSqlGenerator, so you can create a CodeListSqlGenerator object and return the pointer to it as a ICodeListSqlGenerator pointer.
