Resize CSplitterWnd panes

Environment: VC++ 4.0; Win 95

I have nested splitter windows created from  a child frame window using
CreateStatic in OnCreateClient function of the child frame class (as appears
in the following code fragment), my problem that I can't initialize the size 
of the splitters i.e the size of the created panes. the first pane in the
sequence i.e splitter1(0,0) takes the whole window always, and the only way
to show the other panes is manually, isn't there any hint that solve the this
problem.
I've tried the following:
- Initialize the pane size by passing the size parameters to the CreateView
function (they are nPaneX,nPaneY in the example bellow)and it didn't work
- Use explicit call to SetRowInfo and SetColumnInfoin respond to
ActivateFrame (and in other places) and yet it didn't work
- I've tried to use the normal MoveWindow for resizeing and it didn't work
too.

please advice !!!!

BOOL CChildFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext*
pContext)
{
	-----
	-----
	-----
	m_wndSplitter.CreateStatic( this, 2, 1,	WS_CHILD | WS_VISIBLE | WS_BORDER,
								AFX_IDW_PANE_FIRST);
	// add the second splitter pane - which is a nested splitter with 2 cols
	if (!m_wndSplitter2.CreateStatic(
		&m_wndSplitter,     
		1, 2,               // the new splitter is 2 columns , 1 row
		WS_CHILD | WS_VISIBLE | WS_BORDER, 
		m_wndSplitter.IdFromRowCol(0, 0)
			// new splitter is in the first row, 1st column of first splitter
	   ))

	//----------------------------

	if(!m_wndSplitter3.CreateStatic(

		m_wndSplitter2.IdFromRowCol(0, 0)
			// new splitter is in the first row, 1st column of first splitter

use the member function SetRowInfo & SetColumnInfo while you are still in
your OnCreateClient member function. It will work I bet ya!

G'day!

Consider something like

void CFredSplitView::OnInitialUpdate()
{
    CSize doc = GetDocument()->GetDocSize();
    int mode  = GetDocument()->GetDocMapMode();
    SetScrollSizes(mode,doc);
    GetParentFrame()->RecalcLayout();
    ResizeParentToFit();
    CScrollView::OnInitialUpdate();

    //decide where to scroll:
     

    SetScrollRange(SB_HORZ,0,doc.cx,/*REDRAW=*/FALSE);
    SetScrollRange(SB_VERT,0,doc.cy,/*REDRAW=*/FALSE);
    ScrollToPosition(CPoint(ptScroll->x,ptScroll->y));
	
    SCROLLINFO si;			
    si.cbSize=sizeof(SCROLLINFO);

    GetScrollInfo(SB_HORZ, (LPSCROLLINFO) &si);
    si.nMax=m_totalDev.cx;//a protected member of the Base
    SetScrollInfo(SB_HORZ, (LPSCROLLINFO) &si);
    GetScrollInfo(SB_VERT, (LPSCROLLINFO) &si);
    si.nMax=m_totalDev.cy;
    SetScrollInfo(SB_VERT, (LPSCROLLINFO) &si);
}

As I've hacked this out of several methods and jammed it into 1,
I'd be suprised if it works "as is".

Good luck!

   Try this man ...
   Mine is a splitter like the following
  |                          | 
  |         1                |
  |__________________________|
  |           |              |
  |     2     |     3        | 
  |           |              |

   m_wndSplitter.SetRowInfo(0, m_iSplitRowSize, 10);
   m_wndSplitter2.SetColumnInfo(0, m_iSplitColumnSize, 10);
   m_wndSplitter.RecalcLayout();
   m_wndSplitter2.RecalcLayout();

  This code will resize all 3 splitter panes. Try it.

I've already used them and it didn't work, the problem it ignores every
thing, and gives the first pane in the nested panes the whole size of the
child window. Here is the code I'm using:

	SetActiveView(((CMyView1 *) m_wndSplitter.GetPane(1,0)));
	m_wndSplitter.SetRowInfo(1,paneY1,0);
	m_wndSplitter.SetColumnInfo(0,paneX1,0);
	m_wndSplitter.RecalcLayout( );
  
	SetActiveView(((CMyView2 *) m_wndSplitter2.GetPane(0,1)));
	m_wndSplitter2.SetRowInfo(0,paneY2,0);
	m_wndSplitter2.SetColumnInfo(1,paneX2,0);
	m_wndSplitter2.RecalcLayout( );
  
	SetActiveView(((CMyView3 *) m_wndSplitter3.GetPane(1,0)));
	m_wndSplitter3.SetRowInfo(1,paneY3,0);
	m_wndSplitter3.SetColumnInfo(0,paneX3,0);
	m_wndSplitter3.RecalcLayout( );

	SetActiveView(((CMyView4 *) m_wndSplitter3.GetPane(0,0)));
	m_wndSplitter3.SetRowInfo(0,paneY3,0);
	m_wndSplitter3.SetColumnInfo(0,paneX3,0);
	m_wndSplitter3.RecalcLayout( );
