18.4.4..ScrollBar Properties............................................................................

There are two forms of the scroll bars. The horizontal scroll bar allows the user to scroll

in the left and right directions. The vertical scroll bar allows scrolling up and down.

Visual C++ allows you to visual select the desired one and add to it a host. If you are

programmaticall creating the control, you can add the SBS_HORZ style to get horizontal

scroll bar. This is also the default, meaning that it you do not specify the orientation, the

scroll bar would be horizontal. If you want a vertical scroll bar instead, add the

SBS_VERT style:

BOOL CScrollingDlg::OnInitDialog()

{

CDialog::OnInitDialog();

// TODO: Add extra initialization here

Scroller->Create(WS_CHILD | WS_VISIBLE | SBS_VERT,

CRect(200, 15, 320, 148), this, 0x16);

return TRUE; // return TRUE unless you set the focus to a control

// EXCEPTION: OCX Property Pages should return FALSE
