I am writing an application that uses mdi child windows as data entry
forms - that is to say each of my data entry windows are derived from
CMDIChildWnd.
I want to be able to catch the enter and tab presses so that i can
move the focus to the next window in my group.

I can see two ways to do this:
1.) subclass CEdit, CComboBox, CDateTimeCtrl and catch the WM_KEYDOWN
messages.  I am trying this at the moment:
void CMjlEdit::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags)
{
// TODO: Add your message handler code here and/or call default
GetParent()->SendMessage(MY_MSG_ENTERPRESSED, 0, (LPARAM)this);
CEdit::OnKeyDown(nChar, nRepCnt, nFlags);

What is the best way to do what i want?  Is there another way?

Thanks

Do you want to switch between the different MDI child windows on
Tab/Enter, or just do the normal dialog operation of moving to the
next control in the same MDI child window?

If you want to stay in the same child window, then can't you make use
of CFormView, or use IsDialogMessage (which is what does the normal
Tab operations for dialogs)?

If that doesn't fit, probably the best catch-all place is in your MDI
child window's PreTranslateMessage - you should be able to catch the
WM_KEYDOWN messages there and switch the child window activation
without having to sub-class each control window.
