I'm trying to discover why windows beeps when I "tab" through fields. It does
not beep when I "arrow" throught fields and in my code there is no (apparent to
me) difference between tabbing and arrowing. Look at this code

procedure keyPressProcessA(integer self, integer processId, sequence arg)
   integer keyCode, shift

keyCode = arg[1] shift = arg[2]

if keyCode = tab then make tab same as arrows if shift = 0 then keyCode = downArrow else keyCode = upArrow end if end if

keyPressProcessB(self, processId, {keyCode,shift})

end procedure }}}

First off, it's not a problem with Win32lib.  Though v0.60.1 may have a 
function that delimits the beep noise.  The beep noise is to let ya 
know, that your doing something, that isn't supported for that control.  
If you was to put a Single Line Edit (EditText), type something in, then 
press enter, it'll beep at you, mainly because a Single Line Edit (SLE) 
doesn't allow returns by standard forming.  However, if you was to put 
in a onKeyPress event for the Edit Text, search for the Return Key 
(VK_ENTER or VK_RETURN one of the two), and use returnValue(-1), it'll 
prevent the beeping noise, and actually insert the Return into the SLE 
('\n'), though it will appear as a black box.  Hope this analogy helps 
out.  Cause I'm pretty sure, that it's just the tabbing effect that's 
not being supported by the windows control(s) in question.

No matter what you write in your code, it comes down to being logic, and 
only the computer doing as you instructed it to do in your code.

The code snip was nice.  But without the rest of the code I cant test it.
Mind posting a full short example including controls?  I am not currently
familiar with what your calling "arrowing".  I have always used tabs to
change focus.  Arrows for me dont work =) sooo, you are likely talking
about something else than I am thinking of.  I bet however you could
subclass the control to get what you want working.

[code snipped]

It is beeping because the TAB key is being processed by the Edit field's
default Microsoft process. Normally, win32lib traps the TAB key and tabs
around the display, but because you set tabcodes to zero, Win32lib
is passing the TAB press to the edit file.

I would recommend you do the following...

a) Create a new routine to JUST move the focus depending on the UP/DOWN
direction and the current focus.

b) Set a handler to trap w32HKeyPress and if you get a TAB key, call
returnValue(-1). And that's all that this handler does.

c) Set a handler to trap w32HKeyDown. Have this translate TAN keys into
UP or DOWN depending on the shift key. The if you have an UP or DOWN, call
the focus setting routine.

Here is some sample code:

include win32lib.ew

constant mainwin = create(Window, "main", 0, 0, 0, 200,200,0)
constant AA = create(EditText, "AA", mainwin, 10,  10, 150,20,0)
constant BB = create(EditText, "BB", mainwin, 10,  40, 150,20,0)
constant CC = create(EditText, "CC", mainwin, 10,  70, 150,20,0)
constant DD = create(EditText, "DD", mainwin, 10, 110, 150,20,0)

constant WhereTo = {AA,BB,CC,DD}
procedure MoveCursor(integer self, integer keyCode)
    integer shift

    shift = find(self, WhereTo)
    if keyCode = VK_DOWN then
        shift += 1
        if shift > length(WhereTo) then
            shift = 0
        end if

    elsif keyCode = VK_UP then
        shift -= 1
        if shift < 1 then
            shift = 0
        end if

    else
        shift = 0
    end if

    if shift > 0 then
        setFocus(WhereTo[shift])
    end if

end procedure

procedure keyPress(integer self, integer processId, sequence arg)
    VOID = self
    VOID = processId
    if arg[1] = VK_TAB then
        returnValue(-1)
    end if
end procedure

procedure keyDown(integer self, integer processId, sequence arg)
    integer keyCode, shift
    VOID = processId
    keyCode = arg[1]
    shift   = arg[2]

    if keyCode = VK_TAB then -- make tab same as arrows
       if and_bits(shift,ShiftMask) = 0 then
           keyCode = VK_DOWN
       else
           keyCode = VK_UP
       end if
    end if

    if keyCode = VK_UP or keyCode = VK_DOWN then
        MoveCursor(self, keyCode)
    end if
end procedure
setHandler(Screen, w32HKeyDown, routine_id("keyDown"))
setHandler(Screen, w32HKeyPress, routine_id("keyPress"))

VOID = setTabCodes(0)
WinMain({mainwin,AA}, Normal)

Well Derek, although it stopped the beeping tab key the shift tab still
beeps. How could I solve that?<br>

If you can beep in DOS without the speakers on, using this might work in
win32lib.

zBeep = registerw32Function(user32, "MessageBeep", {C_INT},C_INT)
..and just call the function to... beep.
..dunno if 'user32' has become 'w32w32w32w32user32'   :(
