Create a modeless dialog box as child window
Code Sample for this one is Interface.zip
To create the modeless dialog as sibling, follow this
link.
Follow these steps:
- Create a new dialog resource and use the Class Wizard for making a
new CDialog based class for it; lets call it CDropDialog
- In your CFormView-derived class, add a (private) member variable of
type CDropDialog* as a container for the modeless dialog object, lets
call it m_pModeless. In the constructor of your view, make sure you
initialize m_pModeless to NULL
- In your appropriate message handler, lets call it OnModeless,
do the following:
void CInterfaceView::OnModeless()
{
// Display the modal dialog box
if (!m_pModeless)
m_pModeless = new CDropDialog;
if (!::IsWindow(m_pModeless->GetSafeHwnd()))
m_pModeless->Create(IDD_DIALOG1, this);
m_pModeless->ShowWindow(SW_SHOW);
}
In the destructor of the parent window, proof if the dialog has been
closed and release the memory:
CInterfaceView::~CInterfaceView()
{
if (m_pModeless)
{
if (::IsWindow(m_pModeless->GetSafeHwnd()))
m_pModeless->EndDialog(IDCANCEL);
delete m_pModeless;
}
}
