Stopwatch in a web application

General
1

Hi, guys,

I have a web app with a built-in stopwatch timer.

First, there are the following global variables that I’ve created in a module (all Integers):

  1. StartTime
  2. FinishTime
  3. SpentTime
  4. SpentTimeMin
  5. SpentTimeSec

The stopwatch is designed to stop at 10 min.

There is the following code in the button that starts the stopwatch.


StartTime=Microseconds/1000000
FinishTime=StartTime + 600
Timer1.Mode=2

Pressing that button starts the timer with the following code


Dim CurrentTime as Integer
Dim Seconds as String

CurrentTime=Microseconds/1000000

SpentTime=CurrentTime - StartTime
SpentTimeMin=SpentTime/60
SpentTimeSec=SpentTime - SpentTimeMin*60

if SpentTimeSec<10 then
  SpSec="0" + str(SpentTimeSec)
else
  SpSec=str(SpentTimeSec)
end

if RemainingTime<=0 then
   me.mode=0
end if

if TextArea1.Enabled=False and StartTime=0 then
  Label3.Text="00:00"
else
  if SpentTimeMin<10 then
    Label3.text= "0"+ str(SpentTimeMin) + ":" + str(SpSec)
  else
    Label3.text= str(SpentTimeMin) + ":" + str(SpSec)
  end
end

Label3 is the GUI element that displays the elapsed time.

Everything works well except for one thing - if I run this app in two different browser windows, the app in the second window resets the timer in the first window.

My uneducated guess is that this happens because the code is executed on the server side. Am I mistaken?

What is the best way to fix it so that these stop watches do not reset each other when the app is used by multiple users?

Thank you in advance.

The global variables should be attached to the session object and not a module, otherwise they are not separate as far as i can tell.

Thank you, Paul. I will try it out.
