Can I auto re-size a CSplitter on creation for various

I have a MDI three view CSplitter project:
_____________________ ____________
| | |
| View1 | View 2 |
| | |
| |____________|
| | |
| | View3 |
|_____________________|____________|
I can create the views, then when the program starts my left view is
much larger on my 640/480 mode than when I use the same program on a higher
resolution. The views are: view1 is a CScrollView, the view2 is a
CFormView, and the View3 is a CView. I create the view's with the following
code:
******************************************************
BOOL CChildFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext*
pContext)
{
if(!m_wndSplitter.CreateStatic(this, 1, 2))
return FALSE;
if(!m_wndSplitter.CreateView(0,0, RUNTIME_CLASS(CBaseBall1View
), CSize(600, 50), pContext))
return FALSE;
if(!m_wndSplitter2.CreateStatic(&m_wndSplitter, 2, 1,
WS_CHILD | WS_VISIBLE | WS_BORDER,
m_wndSplitter.IdFromRowCol(0, 1) ))
return FALSE;
int cyText = max(lpcs->cy -210, 350);
if(!m_wndSplitter2.CreateView(0,0,
RUNTIME_CLASS(ShowGameNumber), CSize(0, cyText), pContext))
return FALSE;
if(!m_wndSplitter2.CreateView(1,0,
RUNTIME_CLASS(GraphView), CSize(0,220), pContext))
return FALSE;
return TRUE;
}
******************************************************
Is there a way of telling the size of the MDI Child Frame before I call
"CreateView()" so I can use relative coordinates to set my view's sizes?
Thanks,

Look in the LPCREATESTRUCT?

Thanks Roy,
I used your example but changed it a bit(due to my not wanting
exactly an even split), and had an NON_EXPECTED result. I show what I did
below your included text. I am wondering if you or someone can explain
what is going on.
I have a theory, but I am not sure.

Now what I wanted was not an even split view, I wanted the view
to be about 14/18ths the horrizontal distance when I created the split on the
vertical. I was finally able to get the desired split using basically a 1:1
ratio(I kept increasing the ratio until I sized it like I wanted). I thought
this 1:1 ratio would fill up my client area totally?? I am now
"guessing" that when inside OnCreateClient(......) the sizing takes place
"before" my view is actually shown, which is later shown *maximized*
insided the frame.
I also found that when I did a File/New menu command to create a new
window, I had a different split ratio, than the first view created. All new
documents opened would had that same size, not the size of the first one
created. So I used the following code, to basically get what I wanted(it
seems to work). I now get the same size split(basically) on the first
document opened as I do on all following new windows. Can someone explain
what is exactly going on here, and also might I handle the sizing in a
better or different place.
BOOL CChildFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext*
pContext)
{
CRect clientArea;
GetClientRect(&clientArea);
CSize splitView;
CMainFrame* pFrame = (CMainFrame*)AfxGetApp()->m_pMainWnd;
// Added this flag to allow the sizing to know the first time
//created
if(pFrame->FirstFrame == TRUE)
{
splitView = CSize((int)((clientArea.right/18.000)*18.000),
clientArea.bottom);
pFrame->FirstFrame = FALSE; //would not work for my desired
14/18ths size wanted
}
else
{
splitView = CSize((int)((clientArea.right/18.000)*14.000),
clientArea.bottom);
}
if(!m_wndSplitter.CreateStatic(this, 1, 2))
return FALSE;
if(!m_wndSplitter.CreateView(0,0,
RUNTIME_CLASS(CBaseBall1View),
splitView, pContext))
return FALSE;
if(!m_wndSplitter2.CreateStatic(&m_wndSplitter, 2, 1,
WS_CHILD | WS_VISIBLE | WS_BORDER,
m_wndSplitter.IdFromRowCol(0, 1) ))
return FALSE;
int cyText = max(lpcs->cy -210, 350);
if(!m_wndSplitter2.CreateView(0,0,
RUNTIME_CLASS(ShowGameNumber), CSize(0, cyText),
pContext))
return FALSE;
if(!m_wndSplitter2.CreateView(1,0,
RUNTIME_CLASS(GraphView), CSize(0,220), pContext))
return FALSE;
return TRUE;
}
