I have a CMDIFrameWndEx which I am handling OnCloseMiniFrame.

What I am doing now is doing:

CBasePane* pPane = dynamic_cast<CBasePane*>(pWnd->GetPane());
while(pPane != NULL)
{
pWnd->RemovePane(pPane);
pPane->DestroyWindow();
pPane = dynamic_cast<CBasePane*>(pWnd->GetPane());
}

to destroy all the panes within it when closed. I am dynamically
creating these panes. I want these panes gone when the Miniframe is
closed. This seems to work but I am worried this is not the proper way
to do it since GetPane() returns a CWnd* instead, thats why I am doing
the dynamic_cast. Is there a better way to iterate through all the
panes to destroy them?

Thanks.

It really doesn't make a difference what GetPane returns, it is still a
pointer to your object that inherits from CWnd in one way or another. That
is what dynamic_cast is for.

So what you are doing works fine.

Are you deleting the object somewhere? I don't see a call to delete.

It is deleting that is done in OnNcDestroy. I was just wondering if
there was a better way to iterate through the panes.
