CScrollView scrollbar visible?

I'm using a CScrollView and would like to know if the horizontal and vertical scrollbars are currently visible. Anyone know how to do this?

Hmm, you could try

DWORD dwStyle = GetWindowLong ( pScrollView->m_hWnd, GWL_STYLE);

if ( dwStyle | WS_HSCROLL) {

 // has horiz. bar
}

if ( dwStyle | WS_VSCROLL) {

 // has vert. bar
}

SCROLLINFO info;
info.cbSize = sizeof(SCROLLINFO);
info.fMask = SIF_TRACKPOS;

if ( ::GetScrollInfo(m_hWnd, SB_HORZ, &info) )
{
     // scrollbar there
}
else
{
     // no scrollbar available
}

GOOD LUCK

roshmon and jkr,

Here's more specifics on what I'm trying to do. I'm diplaying a bitmap image(CScrollView) in an MDI child window. I would like to constrain the user from sizing the CMDIChildWnd beyond the edge of the displayed bitmap. To do this I'm using the OnGetMinMaxInfo handler in the CMDIChildWnd.  The problem is when the scrollbars are displayed the constrained size must be increased otherwise the scroll bars will obscure the edges of the view. I've tried both of the previous comments and style is always reported as true even if the bars are not displayed.

Regards,
zeekial
