How do I permanently size the view?

VC++ 2.0, Win95/NT

I am writing an app that requires me to have the make the view window a
certain size (350x250 pixels). The frame window should not be able to be
sized. I know how to do this by changing the CREATERSTRUCT structure in
CFrameWnd::PreCreateWnd(). But how do I get the view to be a fixed size
since I do have a status bar also?

Thanks,

There is an easy way to do that.
You'll have to derive you view from CScrollView.
In your view's OnInitialUpdate, make the following calls :
	GetParentFrame()->RecalcLayout();
	ResizeParentToFit(FALSE);

You may trap the display/hide command for the status bar and/or toolbars to 
recalc layout and resize as needed.

Hi,

The following calls should make the Frame be the same size as the view.  The
view may also be a CFormView which itself is derived from CScrollView.  Use
CFormView if you need a dialog based view application.  

	GetParentFrame()->RecalcLayout();
	ResizeParentToFit(FALSE);

Be warned that setting the ResizeParentToFit(FALSE) parameter to FALSE tells
it to resize your frame window in any case, smaller or larger.  If you
create a window larger than your screen you may have a little trouble
closing it down without the mouse.  Test it through the debugger just in case.

However, this will not bind the Frame to any particular size.  You will
still be allowed to resize the main frame unless you turn the max box and
maximize menu items off.  This may be done by setting the frames
CREATESTRUCT through an override on the CFrameWnd PreCreateWindow method as
follows.

// TMT - Override
BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)
{
  // TODO: Modify the Window class or styles here by modifying
  //  the CREATESTRUCT cs
  // only minimize with no maximize menu item - set styles as needed 
  cs.style = WS_OVERLAPPED | WS_SYSMENU | WS_MINIMIZEBOX | WS_BORDER;
  return CFrameWnd::PreCreateWindow(cs);
}

Of course you can do this through the AppWizard if you choose the advanced
options and set your main window styles there.

In order for the above to work you must make the view have a size of 350x250
and not the frame.  You can change the size of a view through a call to
MoveWindow() in MFC applications.

void MoveWindow( int x, int y, int nWidth, int nHeight, BOOL bRepaint = TRUE );
void MoveWindow( LPCRECT lpRect, BOOL bRepaint = TRUE );

You must take care of all the conversions to make this device independant.

Hope this helps.

use the getminmaxinfo of the MdiChildWnd
which is the frame of your view
