Data Source with real time data

hi 

im writing first windows forms app quite while , lot rusty.

im reading realtime data usb device , want display on form. 

the data has number of properties. 

e.g.

car

--speed

--revs

--stopped

i have datasource class reads , sets properties of object.

the front end control needs read data, but, data realtime then, speed, revs or other propery change @ time. e.g. read speed, time read revs, speed may out of date.

i have timestamp seems in efficient check each time. 

so thinking either latch datasource class somehow, or have event fired when data changes has arguments of set values. 

or other technique

any suggestions?

you should explore ajax, or caching (event notification), or sql server notification techniques (sql 2005 only) should able refresh ui based on updates in end.
check both on search engines.
