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

  • What do the constructor definitions in the class hierarchy look like? This error can be caused by an incorrect base initialization in an initializer list. – James McNellis Apr 13 '11 at 12:23
  • Or, more likely, you are using MFC and have mixed up debug and non-debug settings. – James McNellis Apr 13 '11 at 12:26
  • @James McNellis- Constructor definition.. public: CodeListSqlGenerator(IIntelligentCodeListUpgraderParameter *i_intelligent_codelist_upgrader_parameter); } – Greenhorn Apr 13 '11 at 12:32
  • @James McNellis - Yes I'm using MFC, can you brief me little more on debug and non-debug settings what I need to change – Greenhorn Apr 13 '11 at 12:36
  • I cannot, but there are other people who can. I just vaguely remember having had this issue before once; what I did to resolve it I do not remember. – James McNellis Apr 13 '11 at 14:50

    Possibly something about a DEBUG_NEW macro interfering with every other definition of new. – Bo Persson Apr 13 '11 at 19:57

    Do you still get the same error if you write `#undef new` right before the line of code which is causing the error? – Adam Rosenfield Apr 14 '11 at 04:06
  • @AAdam Rosenfield and Bo Persso - No Im no longer getting the error, when #undef new thanks for the suggestion – Greenhorn Apr 14 '11 at 05:00

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.

  • I'm not trying to create ICodeListSqlGenerator object, ICodeListSqlGenerator *i_codelist_sql_generator = new CodeListSqlGenerator(i_intelligent_codelist_upgrader_parameter); Creates reference of CodeListSqlGenerator object – Greenhorn Apr 14 '11 at 05:23
  • Umm... you do realize it actually creates the object and returns a pointer to the new object, right? – Carlos Daniel Gadea Omelchenko Apr 14 '11 at 05:59
  • Yes, an object reference rite ICodeListSqlGenerator is an Interface so I won't be able to create it object – Greenhorn Apr 14 '11 at 06:08
