I just wrote an app to test this, I didn't need any fudge factor.

Here my code:
int CAutoSizeSplitterView::GetHeight()
{
   CRect Rect;
   m_List.GetWindowRect(&Rect);
   ScreenToClient(&Rect);
   return Rect.bottom;
}

//code to resize top pane:

   CAutoSizeSplitterView *pView = (CAutoSizeSplitterView
*)m_wndSplitter.GetPane(0,0);
   if (pView)
   {
      int Height = pView->GetHeight();
      m_wndSplitter.SetRowInfo(0,Height,Height);
   }

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.
