Yeah I think you missed an email. I dont have a clue how to do this was what
I posted.

Since IBX doesnt do this I wanted to get something out to the customers asap
so I thought I could swap to IBX but this causes other problems with filters
and stuff. Basically I'd have to sit down and learn the difference between
IBX and IBO, something I havent got the time to do. Plus in all other
respects im more than happy with IBO and I'm told when I start our third
system which is a complicated read/write updating client management system,
I know IBO will be the one to use. I want to be consistant.

I agree, I just havent done this, because I'm not sure how.

ok I'll try that and post it here.

I totally agree, I've played around with IBX and I definately prefer IBO. I
think my problem is whilst I can write reasonably good apps in delphi given
a little help, the complicated stuff I leave to component builders, like
yourself. I just buy this stuff and plug it in, read the help files and
expect it to work. I realise it isnt always that straight forward, but
basically, I always thought Delphi was a product that because of the VCL/RAD
nature of the product meant that it was relatively simple to develop quite
complicated programs with minimal technical knowledge. And if you dont know
how to do something, you buy a comp that does.

btw sorry for posting that .txt file I thought 29k would be ok.
BTW you say you cant see this newsgroup in a thread. I use the outlook
express newsreader and it threads everthing correctly if thats any help.

Many thanks,
