Make a hidden window the main window of your app, not the dialog:

CYourApp::InitInstance()
{
    ...
   CMainWnd *pMainWnd = new CMainWnd;
   if ( !pMainWnd->Init() )
      return FALSE;

    m_pMainWnd = pMainWnd;

    return TRUE;
}

where

//// [mainwnd.h]

class CMainWnd : public CFrameWnd
{
public:
 CMainWnd();
 BOOL Init();

protected:
 virtual ~CMainWnd();

 // Overrides
 // ClassWizard generated virtual function overrides
 //{{AFX_VIRTUAL(CMainWnd)
protected:
 //}}AFX_VIRTUAL

 // Generated message map functions
protected:
 //{{AFX_MSG(CMainWnd)
 afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);
 //}}AFX_MSG
 DECLARE_MESSAGE_MAP()
}

//// [mainwnd.cpp]

CMainWnd::CMainWnd()
{
}

CMainWnd::~CMainWnd()
{
}

BOOL CMainWnd::Init()
{
    CRect rcWnd (0, 0, 1, 1); // can be anything because window is hidden
    if (!CreateEx (0, AfxRegisterWndClass(0), NULL, WS_POPUP, rcWnd, NULL,
0))
        return FALSE;

 return TRUE;
}

BEGIN_MESSAGE_MAP(CMainWnd, CFrameWnd)
 //{{AFX_MSG_MAP(CMainWnd)
 ON_WM_CREATE()
 //}}AFX_MSG_MAP
END_MESSAGE_MAP()

// CMainWnd message handlers

int CMainWnd::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
 if (CFrameWnd::OnCreate(lpCreateStruct) == -1)
  return -1;

 return 0;
}

But, how does the user make your dialog visible? In my programs,
CMainWnd::OnCreate() creates a tray icon. When the user double-clicks the
icon, CMainWnd gets a message, then shows the modal dialog. You could adapt
this to have CMainWnd show your dialog under applicable circumstances.
