Hi,
I'm implementing a floating window that has a CEditView in it. My host
window is derived from CControlBar and I create a child CEditView() inside
of another child window.

Basically its like this:

CControlBar (dummy registered class DockHost)
CEditView child of CControlBar/DockHost window

I create the CEditView like this:

CWnd* pWnd = (CWnd*)pRuntimeClass->CreateObject();

pWnd->Create(NULL, NULL, ES_MULTILINE | ES_WANTRETURN | WS_CHILD |
WS_TABSTOP | WS_VISIBLE, CRect(0, 0, 0, 0), this, 0, &context);

pWnd->SendMessage(WM_INITIALUPDATE, 0, 0);

It shows up correctly and works fine unless I hit ESC while the CEditView
has the focus. Then it crashes in winocc.cpp in various places. It seems
somehow the CEditView got destroyed. I tracked it down to it seems like
something in user32.dll is sending me a WM_CLOSE.

Any ideas?

I'm not sure why pressing ESC is destroying the CEditView (although pressing
ESC does close a modal dialog). But I would think you could trap this in
the PreTranslateMessage() virtual function of the window containing the
CEditView.
