Does anyone know how to create a MainFrame window without a close box? I
have a SDI application that I would like to close via a dialog box that is
always resident, not the close box of the MainFrame. I would like to keep
the menu and tool bar attached though.

Thanks,
Ron

Hi,

To disable the Close Button on your SDI system menu, you need to add the
following code in one of your frame function:

CMenu *pSysMenu = GetSystemMenu(FALSE);
ASSERT(pSysMenu != NULL);
VERIFY(pSysMenu->RemoveMenu(SC_CLOSE, MF_BYCOMMAND));                
SendMessage(WM_NCLBUTTONDOWN, HTCAPTION, 0L);

Thanks Freist, that disabled the close button. Do you know of a way to
remove the icon as well?

Thanks,
Ron.

Hi,

By design, the Windows allows you to remove the Maximize & Miminize buttons
from the caption bar. The Windows also allows you to remove "all the
buttons"
on the caption bar by removing the WS_SYSMENU style from the
CREATESTRUCT.style. But it does not let you remove just the Close button.  
Disable the Close button is a proper method.

Thanks,
Freist
