Default CH 14 Pages 749-753 Compile Errors


Hi. My issues starts on page 749, Coding the OnMouseMove() Handler and ends on 753, Dealing With WM_LBUTTONUP Messages. When I compile, I get 9 errors:

4 say that m_Color and m_Element are undeclared identifiers. These errors are in the function header for GetElementType() and GetElementColor() in the SketcherView.h file. Both these function header are in the Operations section under public as the book says to do.

// Operations

    unsigned int GetElementType()
    {return m_Element;}
    COLORREF GetElementColor()
    {return m_Color;}

The others say that GetElementType() and GetElementColor() are not members of the CSkethcherDoc.

// Now Select the Element Using the Type Stored in the Document

    case RECTANGLE:
        return new CRectangle(m_FirstPoint, m_SecondPoint, pDoc->GetElementColor());

    case CIRCLE:
        return new CCircle(m_FirstPoint, m_SecondPoint, pDoc->GetElementColor());

    case CURVE:
        return new CCurve(pDoc->GetElementColor());

    case LINE:
        return new CLine(m_FirstPoint, m_SecondPoint, pDoc->GetElementColor());

        AfxMessageBox(_T("Bad Element Code"), MB_OK);

    return NULL;

Hopefully, I have not done something stupid. Any help would be appreciated. Thanks in advance.
