thanks for your reply, sven... you've been a big help with your
responses to my questions...
in answer to your question, yes... the collections are storing pointers
to the records and the records are also pointers to the data (i
think!)... i'm using this line to replace the data in the collection
with the new data if they are not already the same...
PSCRec(aSatCatColl^.At(idx))^.satname^ := asatname;
the data is changing but i'm suspecting that i need to be doing
something more because with the above line in place, i'm getting a lot
of errors like the following... i suspect the problem is that the data
being replaced is a different length that the replacement data?? if i
comment out the above line, my program runs with no errors at all...
What is satname? A pointer to a ShortString or a pointer to a
AnsiString? Did some other part of your code catch (and cache ^^) a
reference to that string?
Regards,
Sven
