    Exclamation Re: regarding CObject and CTypedPtrArray

    Well the problem is that am unable to declare a array as

    CTypedPtrArray<CCmdTarget, CBus*>m_array;

    also am unable to declare a class using class wizard having CObject as its base class the dropdown does not contain CObject as one of its options.....

    1. Please show the exact error messages.
    2. Read MSDN about CTypedPtrArray and its using (particularly, Requirements section)

    Re: regarding CObject and CTypedPtrArray

    Yes, I can do it (add MFC class derived from CObject) using class wizard in VS 2008.
    In VC++6.0 CObject dos not appear in a list of MFC classes available for deriving. However, you could create a new class as a *generic* class and set CObject as a base class.

    if(bCheckBusVer==1)
    {
    if(pDoc->AddBus(p.x-3,p.y-5*s,p.x+3,p.y+5*s,atol(m_BusNo),0,m_BusType,m_Volts,m_LoadAngle,m_BusName))
    {
    int index = pDoc->GetNumBus();
    pDoc->GetBus(--index)->Bus_Draw(pDC);
    }
    else
    {
    bCheckBusOpt=FALSE;
    ReleaseCapture();
    return;
    }
    }
    if(bCheckBusHor==1)
    {
    if(pDoc->AddBus(p.x-5*s,p.y-3,p.x+5*s,p.y+3,atol(m_BusNo),1,m_BusType,m_Volts,m_LoadAngle,m_BusName))
    {
    int index = pDoc->GetNumBus();
    pDoc->GetBus(--index)->Bus_Draw(pDC);
    }
    else
    {
    bCheckBusOpt=FALSE;
    ReleaseCapture();
    return;
    }

    and bus_draw(pDC) as
    char temp[10];
    ltoa(m_BusNo,temp,10);
    if(m_bOrien)
    pDC->TextOut(m_x2+2,m_y2+4,temp);
    else
    pDC->TextOut(m_x1-2,m_y1,temp);
    COLORREF color=pDC->GetBkColor();
    pDC->FillSolidRect(m_x1,m_y1,m_x2,m_y2,RGB(0,0,255));
    pDC->SetBkColor(color);

    the problem is when i run the code and enter the same set of values for size different size of rectangles are made...... ..plzz help me out am gettin sick of this....
