AW: How do you handle the poor performance of LC 7?

[Tiemo Hollmann TB]

Hi Richard,

the scenario is a field to enter a search term. With each entered character
(keyUp) or each backspace (rawKeyUp) correcting the search term I call the
following selecting routine to get a "live selection" of my 20,000 record
list of words. In LC 6 I can enter the chars as fast as I want and this
handler is always "on time" to show me the result list. In LC 7.0.5 it
swallows the entered chars, can't catch up until it stucks completely. I am
not talking of a slow down of 10 or 50%. I am talking about a slow down of
some x100%, which makes the complete handling unacceptable. Maybe my code
isn't very professional, so feel free to show up better style. I have send
Hanson my original real live stack.
Tiemo

Here is the relevant piece of code:

   repeat for each key tKey in garrVideos -- alle Begriffe und Sätze
durchgehen
      if gAktRubrik <> 99 and gAktRubrik is not item 2 of garrVideos[tKey]
then next repeat -- falsche Rubrik
      if tBegriffFlag is not item 6 of garrVideos[tKey] then next repeat --
falsche Kategorie Begriffe
      if gMenuAktuell is "Bearbeiten" and tKey is in tLernlistenInhalt then
next repeat -- Begriff schon in Lernliste
      if tSuchbegriff is empty then -- kein Suchbegriff, Begriff/Satz
übernehmen
         put tKey & cr after tListe
      else -- nach Suchbegriff selektieren
         if tSuchenBeliebig is true then -- an beliebiger Stelle im Wort
suchen
            if tKey contains tSuchbegriff then -- Wort/Satz enthält
Suchbegriff
               put tKey & cr after tListe
            end if
         else -- Suchbegriff nur am Anfang des Wortes
            if tKey begins with tSuchbegriff then -- Wort/Satz beginnt mit
Suchbegriff
               put tKey & cr after tListe
            end if
         end if
      end if
   end repeat   
   if tListe is not empty then delete last char of tListe   -- letzten CR
löschen
   put xSortListe(tListe) into fld "Liste" -- Text ins Anzeigefeld kopieren

Can you post the code for that loop, and tell us a bit about the data it
works on?
