Hi

does any use the bVirtualColumn subclass bCheckColumn

i have set one up - based using a bDBServer
the server is using record filters .... an array of record numbers -
in this case excluded.

When i use the CheckAll nethod, it selects ALL records irrespective of
the filter, and even the scope ?

Or am i doing something wrong ... or is this ludicrously complex ? and
i had better just run thru the all the records ...

Richard,

the implementation of the method bCheckColumn:CheckAll() is very simple and not the best. The method
check all records from 1 to LastRec. I will check whether I can optimize the method so that filters,
scopes and so on are recognized.

Joachim Bieler

Thansk for your suggestion.

In fact I now don't need it because I have to check some other stuff
in related tables - and as I always use "lookups" rather than having a
relation set - I have to parse the whole table [scoped and filtered]
anyway, and the table is ALREADY filtered using bDBServer excluded
records !

Anyway, what I have is working very fast - and that is all that
matters !

Out of interest are there any realistic limits on the exclude and
include size of arrays ? [what you did using blocks of records to cut
doiwn the array size is very good idea]. indeed are there any limits
on bArrayServer ?

regards

Memory limitations come to mind, outside of that only your imagination<bg>

Richard,

If you think about it, you can answer your own question.

What absolute limits does VO place on arrays? This is not a bBrowser
question and I am certain you know the answer. I am sure you have used
arrays. N'est-ce pas?

What practical limits? Well isn't that going to be a measure of
performance? How fast is the CPU, how much dynamic RAM did you allocate?
Remember that bBrowser is written in VO so there will always be
performance limitations based on language. You are going to have to
experiment because what suits me and my processor may not suit you and
yours.

Geoff
