Dialog based tab control app.

Hi,

I want to use tabcontrol on my dialog application. Actually I am able to show the tab control on my dialog but to add the tab page to the control, i have to use coding like one that follows...

        m_pASStatistics.Create(CStatistics::IDD, &m_TabCtrl);
        m_TabCtrl.InsertItem(nTab, res_str, m_pASStatistics, 0);

So, what does CStatistics mean ? I know that its CDialog derived class but why is that needed ?

1. Does it mean that class will get events of that dialog ? like button click or combo selection change ?

2. what does m_pAsstatistics mean ? I saw that its CTabManagerPage derived class member variable but why has that to be created ? Which events will it get ?

Can anybody explain the significance of these two classes and its usage ?
