Re: Modeless property sheet getting destroyed

I am trying to create a modeless property sheet and use it as the main
window
but the sheet gets closed as soon as it opens(displayed for less than a
second).
here is the code:

BOOL CMyApp::InitInstance()
{
PropertyPage* page = new PropertyPage;
CPropertySheet* sheet = new CPropertySheet;
sheet->AddPage(page);
sheet->Create();
sheet->ShowWindow(SW_SHOWDEFAULT);
m_pMainWnd = &PropSheet;
   return FALSE;
}

where PropertyPage is a CPropertyPage derived class.
