1. RichEdit and findText

Its late so I hope someone can supply the answer to my stupid question 
while I sleep!!
  I have a RichEdit in which I'm doing a findText. The findText works 
fine when searching for a single character, but fails to find it if I am
searching for more than one character..

i.e in the RichEdit I have "7028"

This works fine:-
  fnd = findText ( RE, "7", {0,-1}, findDown)
so does this
  fnd = findText ( RE, "0", {0,-1}, findDown)
but..
  fnd = findText ( RE, "7028", {0,-1}, findDown)
returns 0
 Adding the findWholeWord flag also makes no difference..

I'm sure I'm doing something wrong but I can't see what.. Help!

Pete

Will this be fixed in the next version?
(also, when do you think the next version
will be ready?)

 Sorry, that didn't help, below is a cut down example (I'm using XP home
 in case it makes any difference)

include win32lib.ew
without warning
with trace

integer res
object VOID
sequence test
test = "test 123456\nwsw 6543\nsd 567\nfe 989\nty 123456\nyh 780\nhu 613\n"

constant
Win = create( Window, "Serial Numbers", 0, Default, Default, 400, 320, 0 ),
SF = create( PushButton, "Search", Win, 140,250, 110, 30, 0),
RE = create( RichEdit, "", Win , 20, 20, 360, 200,ES_NOHIDESEL),

FindWin = create(Window, "Find", Win, 200, 300, 350, 110, {WS_DLGFRAME,
WS_SYSMENU, WS_MINIMIZEBOX} ),
FindButton = create(PushButton, "Find", FindWin, 230, 10, 100, 25, 0),
CancelButton = create(PushButton, "Cancel", FindWin, 230, 40, 100, 25, 0),
FindText = create(EditText, "", FindWin, 65, 20, 140, 25, 0),
FindPrompt = create(LText, "Find What:", FindWin, 10, 25, 55, 20, 0)

--============================================================
procedure FindButtononClick(integer self, integer event, sequence params)
sequence SearchText
integer Ffnd
SearchText = getText(FindText)
if length(SearchText) then
	Ffnd = findText( RE, SearchText, {0, -1}, findDown)
	if Ffnd != 0 then
		setSelection( RE, {Ffnd, Ffnd + 1} )
	else
		? Ffnd
	end if
end if

end procedure
setHandler( FindButton, w32HClick, routine_id("FindButtononClick"))

--===========================================================
procedure CancelButtononClick(integer self, integer event, sequence params)
closeWindow(FindWin)
end procedure
setHandler( CancelButton, w32HClick, routine_id("CancelButtononClick"))

--=============================================================
procedure Search(integer self, integer event, sequence params)
openWindow(FindWin, Modal)
end procedure
setHandler( SF, w32HClick, routine_id("Search"))

--=======================================================
procedure Run(integer self, integer event, sequence params)
