I've never tried to do what you're trying to do, but perhaps you are
confusing dialog based units (coordinates) with screen units and they are
slightly different. This article talks about it a bit:

I'm sort of grabbing at straws trying to give you something that might give
you an "aha" moment. Feel free to banter back if you need to brainstorm.
I'm sure others here will chime in as well.

Hi,

I'm getting the position of a list control in a CFormView. Then in my
CView class, I'm adjusting a splitter bar so that everything above
that control is visible. But for some reason, I have to multiply my
answer by a "fudge factor" of 1.35 to get it to work correctly.

I am not very experienced with coordinates in Windows but I do know
about the GetMapMode function call which might have affected the units
I'm getting back.

Here's the code that gets the control position -

DDX_Control(pDX, IDC_LIST_STATISTICS, m_List);
...

// CStatisticsView inherits from CFormView
void CStatisticsView::CalcSizes()
{
RECT rectList;
RECT rectDlg;
m_List.GetWindowRect(&rectList);
GetWindowRect(&rectDlg);
//GetParent()->ScreenToClient(&rectList); These two lines didn't
alter the result.
//GetParent()->ScreenToClient(&rectDlg);
m_iTableStartPos = rectList.top - rectDlg.top;
...

Then there's code like this to position the splitter -

m_wndSplitter2.SetRowInfo(0, rc.Height() - iHeight, 0);
m_wndSplitter2.SetRowInfo(1, iHeight, 0);

iHeight is just m_iTableStartPos.

I realise I might not have given enough info but I'm not sure what is
relevant here. Any tips?

Thanks.

Peter.
