Thread: Get a pointer to a 3rd level child window

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

Neat function. Do you know if there is an order in which it goes through the windows and if there is a way that I could pinpoint one child window in particular. Thanks

Pinpointing one child window in particular would require at least one other unique piece of information about that child. For example, if you know the id you could retrieve it with CWnd::GetDlgCtrlID (or ::GetDlgCtrlID) based on the child window handle sent to your EnumChildProc and look for a match.

The questions and answers you're asking and receiving in this thread seem very similar to what you asked and the answers you got here. Given that similarity, I think you should try some of this out and see whether the information meets your needs.

Thanks for the answer. Yes the answers are similar. I'll try it out.
