Help about class and error: C3861

Can someone help me in this error?

in "cDef.h" :

#pragma once

class cDef 
{
public:

    static int STATE_LOGO;
    static int STATE_MENU;

    static int MESSAGE_ENTER;
    static int MESSAGE_UPDATE;
    static int MESSAGE_PAINT;
    static int MESSAGE_EXIT;
};

#include "cDef.h"

class MainGame;
class GameState;


class GameState

    int GAME_STATE_DEF;

    virtual void MessengeEnter(int message) = 0;
    virtual void MessengeUpdate(int message,int keys) = 0;

    }

    if(message == cDef.MESSAGE_PAINT)
    {
        MessagePaint(message,pDC);

Thanks in advance!

Here's what I used to hammer into my students who had to learn C++ coming from Java and always were confused about when to use ::, ., and ->:

• A::B means A is either a class or a namespace name.
• A.B means A is either an object or a reference to an object.
• A->B means A is either a pointer or an object of a type that has operator-> overloaded (a.k.a. "smart pointer")

If you know these, you can also apply them backwards, so that if you have an A and a B, you know what to put in between.

(I think these rules would have to be extended for C++11, but I'm not sure. If you know, feel free to add this.)

You access static variables by using the scope operator :: instead of the member access operator .

Example:

cDef::MESSAGE_ENTER

Also you should be initializing the members of cDef in your cpp file to some value. In this scenario an enum is probably better by the way.

This seems to be obvious once you see it - you declare the member function

virtual void MessengeEnter(int message) = 0;

but call

MessageEnter(message);

(notice the difference between Messenge and Message)
