The document describes adding controls to a progress dialog in MFC. It defines two control variables - a slider and progress bar, and initializes them in OnInitDialog to have a range of 0 to 100. It also includes an OnHScroll handler that updates the progress bar position to match the slider position on scroll events.

1. Progress

7. Add the following variables:
Ctrl ID Var name Category Var type
IDC_SLIDER m_ctrlSlider Control CSliderCtrl
IDC_PROGRESS1 m_ctrlProgress Control CProgressCtrl

8. • Initialize the vars in: CProgressDlg::OnInitDialog()
……………..
// TODO: Add extra initialization here
m_ctrlSlider.SetRange(0, 100);
m_ctrlSlider.SetTicFreq(10);
m_ctrlProgress.SetRange(0, 100);
return TRUE; // return TRUE unless you set the
//focus to a control
}

11. void CProgressDlg::OnHScroll(UINT nSBCode, UINT
nPos, CScrollBar* pScrollBar)
{
// TODO: Add your message handler code here
and/or call default
int CurPos = m_ctrlSlider.GetPos();
m_ctrlProgress.SetPos(CurPos);
CDialogEx::OnHScroll(nSBCode, nPos, pScrollBar);
}
