Urgent Help : What is the best control ???

[serge calderara]

Dear all,

I have an application which is collecting dynamic incoming data and store
them in a list.
I need to dispaly this incoming list with 2 important recommandation :

1- if the incoming item is already present in the control list, I should
not display it
2- if an item is not anymore present i shoulds eb able to remove opnly that
item

For the time beeing I have used a Lisview control. The easiest way to handle
this is to clear all the time the content of the list when new range of data
need to be filled up. This works well but the problem with this si that if
the incoming frenquency data is high, then my list will blink all the time
due to the refresh.

I was wondering which control should I used to handle the addition of only
non existing data and remove of only non existing data without having this
refreshing stuff.

I was thinkinbg also by using a dataset object and datagrid, but this will
not avoid me this problem, if dataset content change, I will need to make a
refresh of the datgrid to show the new values.

To summarize the whole thing what is the best way to collect a frequency
incoming data (like TCP chanel data) and disply them to user by beeing able
to update only data that have change and not doing continuous refreshing
which ia bad for the eyes after a while

thanks for your help
