MODELESS KB interface

[Borje Hagsten]

I'm not sure, maybe it has to be done in WM_KEYDOWN, but what
about setting tMsg.WParam to zero, like:

  SELECT CASE tMsg.WParam
    CASE 48 TO 57
      'Process the numeric keys
    CASE 13
      'Process the ENTER Key
    CASE ELSE
      tMsg.WParam = 0
  END SELECT

I'm using Semen Matusovski's MODELESS dialog idea to trap
keyboard events. It works well for all the additional functions
I wanted to inplement, but it odesn't seem to allow the ability
to throw away keystrokes.

I can get the desired action with COMBOBOX's either with
%CBS_DROPDOWN or %CBS_DROPDOWNLIST styles. With the former I
also get the number keys being pressed appearing in the list
box. But alphabet (and all others) appear too and I want to
throw them away. Only numerics and ENTER are allowed. With a
%CBS_DROPDOWNLIST stype All works but you don't get the
intermediate keys appearing in the box.

What I'd like to do is throw away the mesaages for all other
keys. Would anyone have an opinion on things to try to
infrom GetMessage that sometimes we don't want the message to
be processed (e.g. FUNCTION=%TRUE in a CallBack Function).
