what do i have this error message

[paskal]

I try to crate a class, CComponentObject with the CObject as the base class. Somehow, it generates 125 errors. It seems that the class CcomponentObject is undefined.

The following is header file.

#ifndef _COMPONENTOBJ_H_
#define _COMPONENTOBJ_H_

class COpAmpCView;
class COpAmpCDoc;

class CComponentObj : public CObject
{
protected:
DECLARE_SERIAL(CComponentObj);
CComponentObj();

//Constructors
public:
CComponentObj( const CRect& position);

//Attributes
CRect m_position;
COpAmpCDoc* m_pDocument;

//Operations
virtual void Draw(CDC* pDC);
virtual void MoveTo(const CRect& position, COpAmpCView* pView = NULL);
virtual CComponentObj* Clone( COpAmpCDoc* pDoc = NULL);
virtual void Remove();
void Invalidate();

//Implementation
public:
virtual ~CComponentObj();
virtual void Serialize(CArchive& ar);
#ifdef _DEBUG
void AssertValid();
#endif

// implementation data
protected:
BOOL m_bPen;
LOGPEN m_logpen;

};

the following is .cpp file.

#include "stdafx.h"
#include "OpAmpCDoc.h"
#include "OpAmpCView.h"
#include "ComponentObj.h"
#include "DrawComponent.h"
#include "CntrItem.h"

as I see forgot to put

#endif



to the end of the header file
