You have used very sloppy language here. Do you mean "in the same place, in logical
coordinates relative to the list item" or "in the same place, in client coordinates"?
I assumed that you wanted in the "same place" in the client area, that is, independent of
scrolling, that button would always be, say, in the top left corner. If the button is
supposed to be part of a list entry, then your statement "when I scroll the view down, the
button will not be seen" suggests that your desire is that if you scroll, the button
logically scrolls with the element. If you meant to describe the *actual* behavior you
are seeing, you would have said "When I scroll down, the button disappears, although I
want it to remain visible at the point on the window where I created it". You are stating
things in a very confusing fashion because you are omitting describing the difference
between your intent and what you see in your implementation.
Note that if you want the button to simply stay in the same apparent physical position
within the window, another solution would be to add the WS_CLIPCHILDREN style to your
control. Unfortunately, due to some apparently sloppy thinking and misguided decisions,
they do not allow you an interface to set this style in the dialog editor (apparently
someone said "But who could need to set this style for a *control*?" so instead of just
making all the styles available, Those Who Know Better Than We Do What We Need have not
made it available in the properties list!). I don't know if this is a creation-only style
which cannot be changed or you can change it on-the-fly, so there are two possible
solutions:
(1) try doing a ModifyStyle call to set it, see if that works
(2) it it doesn't work, re-create the control with the style set
(2) is a bit clumsy, but looks something like
CRect r;
c_MyListCtrl.GetWindowRect(&r);
ScreenToClient(&r);
CListCtrl temp;
temp.Create(c_MyListCtrl.GetStyle() | WS_CLIPCHILDREN,
r,
this,
c_MyListCtrl.GetDlgCtrlId());
temp.SetWindowPos(&c_MyListCtrl, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE);
c_MyListCtrl.DestroyWindow();
c_MyListCtrl.Attach(temp.Detach());

Thanks for you answers.
But I have to describe my problem more precisely.
If I place the button at the top of the ListView at the beginning. When user
scroll the view down, the button will not be seen which what I mentioned that
the button should be at the same place as it is initialized. When user scroll
the view up to the top, the button should be seen again.This is the operation
I want to achieve.

But you may want to accomplish this by just putting a different toolbar
under the scroll bar (horizontally or vertically) like MS Office products
do. That may be easier than replacing the scroll bar.

I create a button in a ListView as followings:
// ********** code **************
void CThumbView::OnInitialUpdate()
{
CRect rect;
GetClientRect(&rect);
m_thumbSyncButton.Create( _T("Send"), WS_CHILD | WS_VISIBLE,
CRect(rect.left, rect.top, 50, 40), this, IDC_BUTTON2);
}
// ********** code **************
And I want the button always showed at the same place as it is initialized
even the user scroll down or up the client region of the ListView. I don't
want the button redraw when user scrolls the bar.
