Perhaps someone on the net has a solution or suggestion for the
following problem:

I am trying to set up WinWord-like combo boxes (with CBS_DROPDOWN
| CBS_HASSTRINGS) to allow users to select fonts and sizes from
the list part of the combo, or type them into the edit part.

All is well, except that I want the return key to work the same
way it does in WinWord, namely, it puts the current selection
into the associated edit box, and undrops (hides) the list.  In
my application, typing return when the combo box has focus only
causes a system beep--no notification message or anything.  Of
course, when the combo box has focus the main window proc
receives no keyboard messages, so there's nothing to intercept at
that point.  Moreover, the Guide to Programming explicitly warns
against subclassing predefined window classes (i.e. combo boxes),
so messages can't be intercepted there either.

Obviously since WinWord does it, it could be done, although I
expect WinWord was written with the 2.0 API, so the authors
probably used separate list box and edit box controls.  One
solution might be to use SetWindowsHook, but even if I could get
that to work, it seems like overkill for such a simple problem.

Thank you in advance for your help,

Eric Smith
