Heya all!
Okay, I wonder about this...
I have a search box, but after clearing the search listview and trying
the search again, it crashes. I got down exactly the line it crashes
at, however, I have absolutely no clue why it crashes since I
unfortunatly don't have the full version interpreter quite yet (I'm
working on it), so can someone tell me whats wrong?
Heres where to download the program:
http://oberon.spaceports.com/~lordlev/binaries/napsterparse.zip .
Unzip it into a directory, and run 'exw napsterparse'. Then after its
done loading, press Search. Afterwards, type a search string, like
'limp', and press 'Find Now'. You'll get the results. Then, press 'Find
now' again. It doesn't matter if you changed the string, nothing any
different happens. Now you'll get the trace window to come up, then,
press enter a couple times til you get to the 'getLVItemText' place.
The next keypress leads it to
text=peek_string(lvitem_data[item][2][subitem][1]). And then? It
crashes, and I don't know why, since I have the PD interpreter.
Now, can someone tell me how to fix this? :-\
TIA,

Hello,
Looking at the getLVItemText function I wonder why the id variable is
required since it's not used within the function. Perhaps that is what is
wrong? How does the function know which ListView's data it's supposed to
look at? It got me wondering.

Hi Vince,
I've enhanced this function in v0.56. It now looks like this ....
--------------------------
global function getLVItemText( integer id, integer item, integer subitem)
sequence text
--NEW! v0.56-- Added parameter validation.
text = ""
if item > 0 and item <= length(lvitem_data)
and subitem >= 0 and subitem <= length(lvitem_data[item][2])
and id = lvitem_owner[ item ]
then
-- NEW! v.056-- Subitem of 0 returns all strings.
if subitem = 0 then
for i = 1 to length(lvitem_data[item][2]) do
text = append(peek_string(lvitem_data[item][2][i][1]),
text)
end for
else
text = peek_string(lvitem_data[item][2][subitem][1])
end if
end if
return text
end function
