faq how to solve this error

[fcvcnet]

Hi,
I write a class
class CSegment
{
public:
CSegment(void);
public:
~CSegment(void);
public:
CArray< CList< CPoint, CPoint& >, CList< CPoint, CPoint& >& > m_curve;
CArray< int, int& > m_superindex;
CArray< bool, bool& > m_direction;

};

and in CmaxregionborderView I add a member variable
class CmaxregionborderView : public CView
{
....
public:
CmaxregionborderDoc* GetDocument() const;

public:
CArray< CList< CSegment, CSegment& >, CList< CSegment, CSegment& >& >
m_bordersegmentlist;
....
};

when compile I got error as list below ,how to solve these error? Thanks a
lot.

Hi,
I write a class
class CSegment
{
public:
CSegment(void);

Never write function(void) in C++.

public:
~CSegment(void);
public:
CArray< CList< CPoint, CPoint& >, CList< CPoint, CPoint& >& > m_curve;

This looks horribly like widows code, so you'd better post to windows
development group

Your error is happening in a Microsoft header file, in a Microsoft-specific class.

See the welcome message posted twice per week in comp.lang.c++ under the subject "Welcome to comp.lang.c++! Read this first." or available at
http://www.slack.net/~shiva/welcome.txt

yes, I use vs2005 on windows xp.

Never write function(void) in C++.

I use class wizard in vs2005 to write this class. The code is generate by
vs2005.

Yes , it is windows code, but I think it have some relation with c++ .
Do I have to ask in widows group?
what ever thanks you Ian Collins.

 

[fcvcnet]

Ok, thanks you all.
Now I go to the windows group mfc.

Hint,

Try looking up CObject in the VC8 docs. This error is covered there.

"Compiler Errors when Implementing a CObject-Derived Class "

I didn't realise it was that bad!

Yes, the problem is somewhere in the bowels of a windows header.

Never write function(void) in C++.

there is no reason not to do this

Nor is there one to do it.

Thank you . I have see it.
