Re: ActiveX event and DoModal

// XP TESTDlg.h : header file
//

#pragma once
#include "chessactivectrl1.h"
#include "PromotionDlg.h"

#define _UDM_TEST WM_USER + 100

// CXPTESTDlg dialog
class CXPTESTDlg : public CDialog
{
// Construction
public:
CXPTESTDlg(CWnd* pParent = NULL); // standard constructor

// Dialog Data
enum { IDD = IDD_XPTEST_DIALOG };

protected:
virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV support

// Implementation
protected:
HICON m_hIcon;

// Generated message map functions
virtual BOOL OnInitDialog();
afx_msg void OnSysCommand(UINT nID, LPARAM lParam);
afx_msg void OnPaint();
afx_msg HCURSOR OnQueryDragIcon();
DECLARE_MESSAGE_MAP()
public:
CChessactivectrl1 o_ChessActive;
DECLARE_EVENTSINK_MAP()
void OnPromotion();
CPromotionDlg o_PromotionDlg;
afx_msg void OnBnClickedButton1();
LRESULT OnTest(WPARAM wParam, LPARAM lParam);
};

4) if i click the break button after the debug assertion failed box it
jumps to file:
f:\dd\vctools\vc7libs\ship\atlmfc\src\mfc\dlgcore.cpp (line 492)

HWND CDialog::PreModal()
{
// cannot call DoModal on a dialog already constructed as modeless
ASSERT(m_hWnd == NULL);

// allow OLE servers to disable themselves
CWinApp* pApp = AfxGetApp();
if (pApp != NULL)
pApp->EnableModeless(FALSE);

// find parent HWND
HWND hWnd = CWnd::GetSafeOwner_(m_pParentWnd->GetSafeHwnd(),
&m_hWndTop);

// hook for creation of dialog
AfxHookWindowCreate(this);

// return window to use as parent for dialog
return hWnd;
}

the first ASSERT() failes.

5) i also tried :

void CXPTESTDlg::OnPromotion()
{
// TODO: Add your message handler code here

CDialog o_Test;

o_Test.Create (IDD_PROMOTION);

// This call causes a debug assertion failed
o_Test.DoModal();
}

Why isn't this:

void CXPTESTDlg::OnPromotion()
{
   o_PromotionDlg.DoModal();
}

?
