  hi guys.. i need a big favour.
  im new to delphi..
  

  
  can any one of you tell me how do i setup a timer to show how long did it take to calculate the prime numbers??
  

  
  and whats the best way that i could develop a program that would be able to identify extrateristrial and non-extrateristrial...??
  

  
  thanks in advance

  i havent done any delphi for a while but couldnt you just tell the timer to add 1 on to a variable every second?
  

  
  something like....
  

  
  declare a variable...
  

  
  i :integer;
  

  
  

  
  then create a timer componant... and double click on it
  

  
  then add in this
  

  Code:

  i := i + 1;
  Label1.Caption := 'Seconds = ' + InttoStr(i);

  
  

  
  you could have a small sum to turn it into hours or whatever......
  

  
  hoper this helps

  well, it could run a bit slow but just set the timer interval to 1 instead of 1000
  

  
  then you would have milliseconds...

  Why don't you try to catch the time from the PC clock when you start and finish the calculations and obtain the difference between them?... Maybe this could help you:
