Creating an SDI app without a menu bar...

Is is possible to create an SDI application without a menu bar but with
a tool bar? I tried simply deleting the MENU resource
that was generated by the AppWizard, yet i kept the toolbar resource.
However, running the application causes the following error.
"Failed to create empty document."
What i'm trying to do is create an SDI application with a PropertySheet
in the View and provide only a tool bar and status bar.
any suggestions?
thanks, mark.

Override your mainframe window's PreCreateWindow() function and specify
a zero menu handle:
BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)
{
cs.hMenu = NULL;
return CFrameWnd::PreCreateWindow(CREATESTRUCT& cs);
}

How to Create MFC Applications That Do Not Have a Menu Bar
Article ID: Q131368
Revision Date: 17-JAN-1996
The information in this article applies to:
- The Microsoft Foundation Classes (MFC) included with:
- Microsoft Visual C++ for Windows, versions 1.5, 1.51, 1.52
- Microsoft Visual C++ 32-bit Edition, versions 1.0, 2.0, 2.1, and 4.0
SUMMARY
For most Windows-based applications, a menu bar is a part of the user interface.
The menu bar provides a functionality summary for the person using the program.
However, it is not
required that every Windows-based application must contain a menu bar. This
article describes how to create an MFC application that does not have a menu
bar.
For Windows-based applications generated by AppWizard, the IDR_MAINFRAME menu
resource is the standard menu resource for both SDI and MDI applications. It is
the only menu
resource for an SDI application. MDI applications contain additional menus for
each type of MDI child window they support. Those menu resources are usually
named IDR_xxxTYPE, where
xxx is related to the name of the corresponding document type. Thus, creating an
application with no menus is not as easy for an MDI application as for an SDI
application. You basically
have to modify all functions related to loading and switching menus.
MORE INFORMATION
Steps to Create SDI Application That Has No Menu Bar
1. Generate an SDI application with AppWizard. Do not delete the
IDR_MAINFRAME menu resource. If you have an application that was not
generated with AppWizard, do not delete the corresponding main menu
resource. Leaving the menu resource is required to avoid assertion
failures in the MFC code.
2. To prevent the main application window from having a menu bar, delete
the already loaded menu, and set the hMenu field of the CREATESTRUCT
structure to NULL in the CFrameWnd::PreCreateWindow() function:
BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)
{
if(cs.hMenu!=NULL)
{
::DestroyMenu(cs.hMenu); // delete menu if loaded
cs.hMenu = NULL; // no menu for this window
}
return CFrameWnd::PreCreateWindow(cs);
}
Steps to Create MDI Application That Has No Menu Bar
1. Generate an MDI application with AppWizard. Do not delete the
IDR_MAINFRAME menu resource. If you have an application that was not
generated with AppWizard, do not delete the corresponding main menu
resource. Leaving the menu resource is required to avoid assertion
failures in the MFC code.
2. Delete menu resources associated with MDI child windows (IDR_xxxTYPE).
They are not used. By deleting them, you avoid a resource (memory) leak.
3. Override the PreCreateWindow() function for the CMainFrame class:
BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)
{
if(cs.hMenu!=NULL)
{
::DestroyMenu(cs.hMenu); // delete menu if loaded
cs.hMenu = NULL; // no menu for this window
}
return CMDIFrameWnd::PreCreateWindow(cs);
}
4. Modify the code responsible for switching menus by overriding
the LoadFrame() and OnCreateClient() methods of CMainFrame. This
is necessary because MFC has already loaded and switched menus
automatically. The following shows what must be done:
// Overridden method declarations for CMainFrame
BOOL LoadFrame( UINT nIDResource,
DWORD dwDefaultStyle = WS_OVERLAPPEDWINDOW | FWS_ADDTOTITLE,
CWnd* pParentWnd = NULL, CCreateContext* pContext = NULL );
BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs,
CCreateContext* /*pContext*/);
// Overridden method declarations for CMainFrame
BOOL CMainFrame::LoadFrame(UINT nIDResource, DWORD dwDefaultStyle,
CWnd* pParentWnd, CCreateContext* pContext)
{
return CFrameWnd::LoadFrame(nIDResource,dwDefaultStyle,
pParentWnd,pContext);
}
BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs,
CCreateContext* /*pContext*/)
{
return CreateClient(lpcs,NULL);
}

Is is possible to create an SDI application without a menu bar but with

that was generated by the AppWizard, yet i kept the toolbar resource.
However, running the application causes the following error.
"Failed to create empty document."

any suggestions?
