Resizing an OLE control

Hallo,
I have a tiny problem with my MDI application. At startup I can't get my OLE
control (derived from CWnd) fitting my CFormView (parent of the control)
client area.
Here is the OnSize overridden of my CFormView class:

void CMyFormView::OnSize(UINT nType, int cx, int cy) 
{
	CMyFormView::OnSize(nType, cx, cy);
	
	// TODO: Add your message handler code here

	CRect size;
	GetClientRect(&size);
	
	if(IsWindow(m_grid.m_hWnd)) m_grid.MoveWindow(&size);//m_grid is my OLE control
	
}

the first time the view is shown, it contains the control not fitting its
client area.
As soon as I resize the view everything works fine.


Any suggestion about?

Thanks.

What I did was:-
CRect size(0,0,cx,cy);
if (m_grid.GetSafeHandle()) m_grid.MoveWindows(size);

The code above performs flawlessly in my app.

 Hi! You are probably creating your control in the OnInitialUpdate(),
right?
During the creation of the MDI child there are two calls to OnSize()
member, 
both BEFORE OnInitialUpdate().
 Try to create your control in the OnCreate() right after the call to
the base class
OnCreate(). At least, I've tried this in my VC 4.0 and it works.

BTW, this is kind of new in VC++40. In VC 1.5 and 1.51 one of the
OnSize() calls 
occures AFTER OnInitialUpdate().

Try doing the size in your OnInitialUpdate.

Hallo,
I have a tiny problem with my MDI application. At startup I can't get 
my OLE
control (derived from CWnd) fitting my CFormView (parent of the 
control)
client area.
Here is the OnSize overridden of my CFormView class:

void CMyFormView::OnSize(UINT nType, int cx, int cy)
{
	CMyFormView::OnSize(nType, cx, cy);
	
	// TODO: Add your message handler code here

	CRect size;
	GetClientRect(&size);
	
	if(IsWindow(m_grid.m_hWnd)) m_grid.MoveWindow(&size);//m_grid is my 
OLE control
	
}

the first time the view is shown, it contains the control not fitting 
its
client area.
As soon as I resize the view everything works fine.


Any suggestion about?

Thanks.
