Differentiate real time data
-
Hi friends i have a simple problem. I have time information (Count Down Time) comming from the socket every one second. I want to take a difference of the current value from the previous value of seconds. eg if current value of second is 10 and previous was 9 then i want to subtract 10-9. How can i do it programatically. Please suggest. Thank u all in advance.

Hi,
Keep a copy of the last value received, subtract the new and store it in place of the last one.
There isn't much more than that
Hope it helps

If you are using static variables for that you are probably doing it wrong.
You don't need them for this kind of problem

Hi SGaist i have implemented using static variable only and it is working also.
I am putting the last value in a static variable every time after taking the difference of current and last value. I have implemented it using timer. On every timeout of timer i read the current value and put the current value into ststic variable lastvalue. In this way my code was solving my purpose.If u can suggets a better and accurate solution you are most welcome and plz explain how to do that??

I didn't say it would not work, but you are using the wrong tool.
A class member is better suited for that
