CFileDialogImpl extends in Windows Mobile Message Problem

class CPictureOpenDlg : public CFileDialogImpl<CPictureOpenDlg>

{
public:
	
	CPictureOpenDlg( // Supports only FileOpen
		LPCTSTR lpszDefExt = NULL,
		LPCTSTR lpszFileName = NULL,
		DWORD dwFlags = OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,
		OFN_EXFLAG ExFlags = OFN_EXFLAG_THUMBNAILVIEW,
		OFN_SORTORDER dwSortOrder = OFN_SORTORDER_AUTO,		
		LPCTSTR lpszFilter = NULL,
		HWND hWndParent = NULL)
		: CFileDialogImpl<CPictureOpenDlg>(TRUE, lpszDefExt, lpszFileName, dwFlags, lpszFilter, hWndParent)
	{
		m_ofn.ExFlags = ExFlags;
		m_ofn.dwSortOrder = dwSortOrder;
	}

	BEGIN_MSG_MAP(CPictureOpenDlg)
		CHAIN_MSG_MAP(CFileDialogImpl<CPictureOpenDlg>)
	END_MSG_MAP()

	void OnInitDone(LPOFNOTIFY lpon)
	{
		MessageBox(L"OK");
	}
}

In Windows Mobile Programming, Does not run override function

Nerver show error and "OK" MessageBox!!

I thought Message not to send my class. so I modified "CFileDialogImpl" BUT NOT MESSAGE HAPPEN!!

template <class T>
class ATL_NO_VTABLE CFileDialogImpl : public ATL::CDialogImplBase
{
public:
..
..
..
// Message map and handlers
	BEGIN_MSG_MAP(CFileDialogImpl)
		MESSAGE_HANDLER(WM_NOTIFY, _OnNotify)
..
..
..
	LRESULT _OnNotify(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled) {
		MessageBox(L"Notify");
		return 1;
	}

Also Never show MessageBox..
