How can I check the amount of time taken by a procedure. I look for a timer which could count the time during procedure execution. Maybe somebody have an assembler code to system timer interrupt, cause it could solve this problem.

using the formatdatetime() procedure at the start and end of the procedure can give you the elapsed time.

uses DateUtils,


procedure MyCode(sender: TObject);
var X,Y: TTime; Z: Integer;
begin
 x := Time;


 your code here



 y := Time;
 a := SecondsBetween(x,y);
 Label1.Caption := IntToStr(a) + ' Seconds elapsed.';
end;
 

Note: There is also a MilliSecondsBetween, used the same way;


Good Luck

Oops.

Forget the FormatDateTime reference in the previous comment.

Crap  :)

Change Z: Integer to A: Integer;
in the var line.  

I need more sleep.

not a good choice,
gettickcount is much more correct,
because it has not so an overhead as the time-function
