Get a pointer to a 3rd level child window

[axr0284]

Hi,
I am trying to get a pointer to a child window that is down 3 level from the main window.
The only thing I can start with is AfxGetApp()->m_pMainWnd. This gets me a Cwnd * to the main window. From there on, I have to find a way to get to a certain child window. Can anybody let me know if they are aware of a way to do such a thing. I am using MFC dialogs. Thanks

Do you know the Resource ID of the Window ? If so, there are a few easy ways you can use to retrieve the CWnd*, otherwise if its a dynamically created CWnd, you will need to store a CWnd* to it ahead of time.
